Sir. Was adding more motor. Will give more increase speeds? Example i used 80km ebike motor and i want to add more e bike 80km motor. And is that even possible? I hope i got cleared answer soon.
Yeaahh... 2WD is the ultimate in performance and efficiency, people would be surprised the amount of POWEER that two very little motors can produce when combined and overvolted. So far from experience, two wheel drive generates a lot less heat and much better acceleration. The UBCO 2WD farm bike got two big MAC motors, in this case there's enough power to lose front wheel traction in some occasions (uphill off-road specially). Surprisingly, that doesn't make you lose control at all but actually helps pointing the bike to the right direction in my opinion, I actually LOVED that feeling!! Despiting my ideas of fun 2WD it's recommended to have a bit more POWER at the rear wheel like 60% rear and 40% front (this can be done via programming)Some 2WD decrease front wheel power at higher speeds, some completely switch it off. Some people like the idea of having 2x throttles, one for the front and one for the rear.People have different opinions on what is best, everyone's ride is different, so there's no right or wrong here. *love the outdoor video idea.. audio was actually fantastic for a beach video!
Thanks :-) I was wondering whether it may cause any problems with motors during cruising if the power is not equalized on both wheels but yeah, there shouldn't be.
Hey man I am having trouble trying to accomplish two hub motor, so I got a rear 72v 12000hub motor on my e bike but i want to add a front hub motor maybe like 8000w hub motor and i at the moment I am using a 150a controller to a 48ah lithium Panasonic cell battery, if I add the extra front hub do I need a extra controller or battery or even the voltage analysts, since there are two different hub motor will they miss up my controller ?
I've been Trying to build and ebike for the longest time with NO luck, I'm Super Glad I came across your Channel! My next project I will be trying again Now!
Thank you so much for this video!!! I got me a 2nd motor and battery and was stressing on how and where I'd mount a second throttle and try to somehow link them together by mechanical means. I am SO glad you can simply combine the signal wires! :D THANK YOU!
I'm a big fan of electric bicycles. I bought one two months ago and I love it. But the reason I'm commenting is your location brings back great memories of my past. I've been there on that beach. I ate delicious Gyros wraps there and I went to the night club there near the circle end where you stood at the end of your video. By the way, I've been wondering about two motors for more torque and quicker acceleration. Nice video
Hi. Can you also provide information on how to setup both bafang mid drive and front geared hub with the same technique you have used on this video? Thanks in advance!
My question is why stop at two motors and add a midmount motor as well? Three! It would be like two people pedaling it, wouldn't it? ( And of course, a real high amp battery).
Heya Mike.. you can usially filter out the wind noise with what I call the "PB filter" (removes the explosive wind noise when saying P or B into an unprotected mike). Despite the name, it's pretty simple. You just select the part of the audio you wanna filter (you can use audacity. Free and open source) and set an equalizer effect in which you silence the lower frequencies. First 1-2 bars all the way down, the rest gradually go up in a sharp curve spanning no more than 1-3 bars. This filters out the bass. Disruptive wind noise is mostly bass
If I have two separate batteries for the two motors, would I need two throttles? Or could I just hook the throttle power wires to one controller and the signal wire to both controllers?
ebikes.ca carries a throttle splitter cable, or you can make one, just connect both controllers to the same throttle, the problem is not all are wired the same but you have 3 wires, one power, one ground and one signal, as long as you match those, your good to go. But I have seen some guys like to have a throttle on each side.
Yep. Copenhagen here. Almost no ebikes! On my commute through downtown I´ve rarely seen ebikes apart from the granny type or bewildered tourists on the overly expensive municipally sponsored clunky ebikes. It feels like my BBSHD 52V is VERY exotic in a place where almost 30% of commute trips are on a bike. I´ve NEVER through a ½ year of ebiking been overtaken by another bike (or moped for that matter). I should set up an advanced building shop for our type of ebiking, as it feels not much is going on in DK. Ponder ponder... - And thanks Mica for the heads-up on endless FB on the AliExpress sale 11/11 2016. It just came at the right moment :).
Thank you so much for making this video! I've been trying to plan out a Hybrid Moped project, just to boost its speed to work as a daily commuter without violating local laws. But, I failed Circuit Analysis in college soooo this electrical stuff was a bit beyond me 😅 You summed everything up great, though!
Good stuff Micah. As your video is a few years old now, has some of the parts needed become cheaper or more expensive as Ebikes have become more popular? I am a beginner here but I am down! Thanks
Wow I've never heard of having two motors for an ebike. I've been considering making my own frame from scratch with my powertig welder. It would be great if I could design it so the batteries are very low to keep the center of gravity down.
I want to create an ecycle from scratch. I figure I can cut the frame with my powerplasma cutter and tig weld everything with my everlast welder but I'm lacking some dimensions for the frame to mount the motors and batteries so that they are low to the ground.
Oh crap bro, I just found out that you live in Tel Aviv. Man, I pray that you, your people, and neighbors would live in peace and harmony so you could add prosperity to it and grow your business 🙏
Hi, I'm interested in a 2wd with only 1 controller system. I like your idea but, I would like less bulk. It's theoretically no. BUT it does work but I'm have some minor setbacks.
When the wind is destroying your audio, try dropping the bass using a (High Pass Filter in your equalizer) This will take out the lows and allow your voice to carry through the video. Or you can drop the EQ ~6Db+/- in the 60-120Hz range in the video editor (I assume it has that capability) Thanks for the diagram. neat setup!
Just caught up with your video today because of my interest in building my own ebike. I bought a Sondors Fold ebike last year and am hooked on commuting by ebike. I live in Chicago and we do have a change of seasons here. I'm of the opinion that a two motor bike is more practical plus I want more speed. I'm learning from you and hope to give you an update after completion of my own bike with a photo. Thanks fir your insight, your new friend, Alfredo.
Hi Micah. I wanted to ask. If you wanted to put a regenerative system in place, to recharge the battery and perhaps even have a fold out portable 100w solar panel to add more range and charge. Living in Israel you should be able to get a load of extra power. Is this possible to do. Is it feasible or not worth the extra cost.any advice on regenerating systems like the freewheeling types. Look forward to now going through your videos. Awesome 👏 🤙😎🤙
Best bet is to hook one brake lever up to each controller, so one brake lever cuts power to one controller, then connect the pedal assist to one controller normally while running a jumper from the signal wire of the pedal assist to the second controllers PAS sensor.
Just for curiosity, and for the long distances treckers, could you put a moter that just generates but not for drive on the front wheel to charge as they go or make a trailer with a generator on the wheel?
mike nice vid , still missing a few parts , how do you connect your pas sensor , and your display , or you dont need it ? my tought was when i use your setup , without cycle analist , i dont have , how does the controllerS know in which speed or pas lvl both wheels or both controllers are , since you only use power and throttle of 1 controller
grate video thanks for the insight. I have one question with you adding an extra motor how has your range been hindered have you done any test with just the one motor compered to both ?
What about using 2 battery packs and the BMS on each to control the max amps and everything? That's how I would do it since I want to draw low nominal voltage and amps from each individual cell anyway. Sure the controllers and thus the throttle might always be offering max power, but the battery won't be giving up too much at one time. Am I missing something obvious?
Nice way to get around the single motor rule. could you in theory also have several motors surrounding a central shaft like an old radial engine. 5 small motors producing a large combined power output.
This is fine in a straight line, but what about tight bends/corners? Is there any problem with the wheel speed difference? On the sand, the back wheel looked to be kicking out as it pushed against the front.
Hi, I have the Walmart eride 29. Is there an easy way to add a front hub motor w thumb control? Use existing magnet pedal sensor and maybe a water bottle battery? For occasional hill boost?
I had a thought...what about the pedal assist? How would that fare with the ebike as well? Would it have to be all 3 wires to one controller, then the other controller just gets the signal, or would it be the same?
Great Work...... You are really filling a fast growing need for eBike info. I remember a couple of years ago when it was very difficult to get info/parts and now we are on the cusp of an eRevolution, Thanks so much for being a facilitator. . . . . . . . //// ?(1) avail of eBike hubs for small wheels (16" & 20")? . . .We ride recumbents and I look forward to adding ePower in next year or so. ( BikeE , Vision R40, Velotechnik Grasshopper ) //// ?(2) Can you charge a lithium too often? or should you let them run down before charging?
I am wanting to do this to my ecotric sportcool fat tire bike you reviewed not to long ago. Would you be able to do a current video on making that bike dual motor?
May be a good upgrade for mine some day and would probably just put a switch in to turn on 2x2 mode when I need it. Some kind of cruse control would be nice too.
Thank you Micah so much for this. I found a kit on Aliexpress for a dual set up for front and rear 500 watt Bafang motors. There is only one controller at 48 volts and 500 watts. I am trying to find the specs for the controller. Can one controller do the job? Is two 500 watts motors through one controller like a 1000 watt motor? A lot of newbie questions. Is this the best place for the questions?
how do you over voltage your motors? also how would you support your bike to handle higher powers. I want to take 2 1000watt hub motors and have both hooked up and over voltage but I'm not sure how to go about it and how to beef up my bike to handle the high power and high torque. thank you for your videos and insite
This is exactly what I need... Dual motor set up. Is it possible to add a 48V 1000 watt front wheel hub motor 26" x 4.0 fat tire bike? As my current ebike is 48V 500 watt rear motor with PAS. I find it difficult going up hills in my neighborhood, as I haul my two children in a Thule Coaster XT. Now, is it possible to add a conversion kit to the front? Can the front wheel also be connected to PAS as the rear wheel is already set up. I guess, id have two displays on my handle bar. What if I don't connect PAS, and only use thumb throttle only when I need the extra help going up the hills. I currently use PAS 2, and sometimes 5. So I guess it be nice to have PAS set up on the front hub, but now how do I go about connecting it to a pre-existing ebike setup. Any thoughts or ideas or sources that would help me accomplish this goal would be much appreciated.
As of today March 2018 we have very few ebikes in Manchester UK. I did your test and 10 out of 10 were pedal bikes. And that was on a major road leading into the city centre.
Hi, You will get a 2WD controller 36V/48V both. This controller got two wire for motor, one is back and one is for front and remaining everything is same as your normal kit. Try it!
I would like to know if you have used your bike on steep off road trails? I have two Honda trail 110's I love them but they loose traction on steep hills here in Montana. Would a two wheel drive bike have the low range power like the Honda has but wheel the traction of two wheel drive?
New to everything involveing e bikes, and I was wondering what the cheapest way to get a lithium battery that could get me at least 15 mile range is? Should I make my own or buy one, if I should buy, where should I buy one? And if I build, what's the cheapest way to make a reliable and safe battery pack?
Its said that these electric motors will still get moisture inside and eventually rust up and cause motor to go bad, for the amount of time you've used your bike have you ever opened up your motors to check the conditions of internals, or have you did an internal water proofing method.
My plan is to add a 3000w front hub motor to my current 1500w rear hub setup. I'll be adding a second 60v battery for the new motor and connect throttle to both controllers. See any issues here?
Stick two pedal assist controlled hub motors on a mid mounted e bike for a stealth triple motor machine. So long as the hub motors are capable of freewheeling the operation of the original mid drive motor will be unchanged, but when you pedal the hub motors kick in for extra power and 2wd traction. You can cruise around on the mid drive motor using minimal battery and power up steep hills with all three motors.
I am wanting to use two front electric hubs to build a electric car for my grandson, and I plant to make it look like an old ford 1920 model “t” I could definitely use help in what would work best. I am building it so he can grow up with it. For now Dad could ride him around until my grandson can handle it in his future.
Could you please describe E-Bike Hub Sizes. What bike frames are suitable for say Bafon Hub motors? What Frame measurements do you need for 4 Inch Fat Tires? What E-Hubs are required for 4inch fat tires? What measurements do E-Hubs require? Do they come in different size widths?
What are your thoughts on the uni pack power batteries? I just bought a 52v 13ah and so far it's great. I've built my own a few times with your help. Just wondering if you could do a video with one of there Chinese cell batteries. Seems very well built, but I'm no expert.
Hi. I like tinkering with things and I was wondering if this wiring diagram works for a mid drive and a rear hub with each drive system having its own battery. Or what else is needed. If this is in your book. Which one should I purchase. Thank you!
hey mika great videos by the way u have a great sense to speak to every type of person okay here is my quick question im sure u stay busy i got this 2000 watt 60V/64V 27A-32A Dual-mode controller thats has an electric racing car painted in the front of the box with Chinese letters & english words STRONG POWER ontop but the controller only has 1 set of all 3 yellow motor phase wires instead of blue, yellow & green so can u help me out with this im trying to put this on my small e bike with 2 48 volt 500 watt motors and my battery is a 12 in parallel 14 in series to give me 60 volts but how do i wire the both motors to the same controllers hall sensors
hi nice video i have an hub motor and gearless motor one has 9pins and the other has 8pins can they both work if two speed controller are conneccted im not using waterproof connector i have brushless speed controller. one speed controller has 6 hall sensor and the other speed controller has 5 hall sensor pins so i was wondering can it work
What would you suggest for someone such as myself that has a recumbent with different sized wheels? I'm looking at possibly having a 250w on front 20", and a 500w on rear 26" (750w max here in Texas). Thinking have the 250w front on all the time, and just use the rear 500 for up hill boosts, or when I have a trailer to get a longer range on the battery. They would be on a cadence sensor instead of a throttle.
Hi, thank you. What are the issues of using hub motors of different power? Are there these issues even when limiting their speeds to the minimum of their maximum speeds? Thanks!
I was looking at those, (1000w per wheel), and it would be $400 plus bike and whatever battery you wanted to use). To me, that seems very cheap. Since I'm not worried about weight on an E-bike since its going to be heavy (this wouldn't be like me replacing everything with carbon fiber on my road bike), I could just get a gently used fat bike for $150 (my cousin has one of those, we've thoroughly abused it, and it looks and rides like new, I don't plan on doing ledge drops like I typically do). Seems like $550 plus some high powered LiPo batteries (to keep it moderately light weight) should be able to rip around and have fun!
@@jakegarrett8109 $199 48v 1000w front or rear. Slightly under size rim..still takes a 4" tire. Controllers are cheap- I upgraded 1 with pure sine which is about 25% better. $700 2 kits and a bike. $800 mid mount 48v 1000w.

Hello and thank you for your video. Can you use the rear motor with cycle analyst for pedal assist and front motor for throttle only, by using 2 throttles and one cycle analysis. I am in the market for ebike and would love to start with something different
Thanks for your videos. Can I hook up 2 front hub wheel to a recumbent tadpole trike with an existing bafang mid drive? Wondering if the 2 front wheel need to be calibrated to spin at the same speed? Or a quad with 4 hub motor or 2 hub and mid drive combo?
Micah great vid. Other than the traction improvement (2wd) is having 2 motors more greedy on the battery front even if you lowered the amps draw. So does this reduce the range? Even as you say each motor helps the other motor out. So my question is 1 larger motor or 2 smaller motors?
What's the battery voltage and also amphours like is it a 48v battery with 20amphours and do you.connect both controllers into that , as ya shown ?? And also are you getting less distance having both motors to one battery or is this because you went with a smaller watt battery for the wheels ?? If you go higher for wheels connect controllers to battery less distance etc etc And what's the average distance for this set up.you have awd both tires going qt once , like run time about 10 miles ?
Great information and thanks for sharing. The "all-wheel-drive" advantages are irrefutable - and must be GREAT FUN to ride! I can see where it would be very useful to have the option to readily switch/select either only FWD, or RWD, or AWD. Can you please show and explain how this could be readily optioned? With Thanks
hey nice videos, You inspired me to make my own diy eBike. As you mentioned in your video how often does the police stop an ebiker? I live in germany and we can only have 250w motor with out going into registration stuff.
I can only answer this question in terms of Israel, where I live. Here the police do operations about once or twice a year where they round up all the illegal ebikes they can find. So you're fine most days, but its a surprise when the next raid is. Having a giant black motor the size of a dinner plate is a dead giveaway for the police that your bike is illegal.
Wow. Where I live in the US, there are absolutely no restrictions on ebikes or bicycles. None. If it was originally manufactured as a bicycle, you can put a V8 on it, and you're fine, as long as you don't break any traffic laws. No registration, tags, insurance, etc on mopeds under 50cc either.
In Germany, the Netherlands and some other EU-countries there are more limitations: - throttle driven e-bikes are not considered bicycles - the motor may only support speeds up to 25 km/h +/- 10% - it should be peddle assist above 6 km/h So why overvolt your e-bike? If you go faster than 35 km/h police will certainly get suspicious. I would say it is only useful to overvolt if you carry a lot of weight and still want to ride around 27 km/h. Especially in Germany insurances can get nasty when you cause an accident with an illegal e-bike. They will claim you are not insured at all because you are technically riding a motorcycle which is not insured separately and you probably weren't wearing a helmet either.
Can you make a video on how much voltage depends on speed and what voltage motor to use 24 or 36 also if I choose to use 24V motor and 10.2 Ah battery how will the range and speed affected. Please answer my question.
So if I run 2 controllers without Cycle Analyst , do I need to use two display,s to power the controllers on and use PAS please explain a little more can I run lights and brake lever motor cut offs ?
I want to be able to sync the wheel speeds of a front hub motor and mid drive motor on one bike for all wheel drive. I know it can be done and I came to you because I know you can solve it. Bafang M620 for the mid drive and 250w or 350w Bafang front hub. Thanks so much!
I'm trying to setup my e bike to get to work but don't really want to use a lead acid battery. Would love to learn to build my own battery. The old batteries I have are lead acid but I'm not sure what to do.
Ok legal and traction issues, perfectly clear but what about power efficiency ? I assume 2 geared motors must must be less efficient than 1 power equivalent gearless motor . Do you know any serious comparison between gear and gearless hubs ? thanks! great channel
Now add a mid drive
Yeah, soon three motors ebikes...with torque vectoring etc...etc
Soon
👍
✌️
😇
Add a 4cycle go full hybrid
And a 80cc petrol engine make a hybrid
🤣
LoL
OR... you could go into the settings on a standard lcd controller and reduce the maximum current draw there! Much cheaper
@Myles Grant godamn scammer

How much average charge duration do you get with 2wd ebikes? Longer using 2 seperate battery packs or with one larger pack? Thanks.
I was actually thinking of building it with two throtles,each for an engine.
two 1000w motors.
What about hill or trail climbing with 2WD?
I was wondering how I could do this and you explained it well, and quickly. Thanks.
I've been Trying to build and ebike for the longest time with NO luck, I'm Super Glad I came across your Channel! My next project I will be trying again Now!
Micah how would one go about connecting the Pedal assist with the two motors? Can you splice them to each controller with no signal loss??

Hi Micah, great video. Could you please tell us how to include an LED or LCD display other than CA? At the very least a volt meter.
Does this setup include assisted-pedaling or it's just the throttle ?
What kind of controller or setup I'd need to recuperate energy, to charge batteries on downhills or stops?
When the wind is destroying your audio, try dropping the bass using a (High Pass Filter in your equalizer) This will take out the lows and allow your voice to carry through the video. Or you can drop the EQ ~6Db+/- in the 60-120Hz range in the video editor (I assume it has that capability) Thanks for the diagram. neat setup!
On this specific bike, what battery did you use and what is your range on it?
Very informative video. Can I add a front wheel motor to a bike with a centre drive 36 v motor?

This is great, thanks! What about connecting one set of brakes and one pedal-assist-sensor to 2 controllers? Thanks!
Best bet is to hook one brake lever up to each controller, so one brake lever cuts power to one controller, then connect the pedal assist to one controller normally while running a jumper from the signal wire of the pedal assist to the second controllers PAS sensor.
On your two-wheel drive bicycle could you use one bigger controller and then spliced the motors together?
You will be able to make a video where you show how to connect a standard ebike monitor to two controllers?
Just for curiosity, and for the long distances treckers, could you put a moter that just generates but not for drive on the front wheel to charge as they go or make a trailer with a generator on the wheel?
Can you route a PAS sensor to both (similar to the throttle setup) or can you only connect a PAS to one?
Do you have a test video on this, showing the performance in challenging terrain?
mike nice vid , still missing a few parts , how do you connect your pas sensor , and your display , or you dont need it ? my tought was when i use your setup , without cycle analist , i dont have , how does the controllerS know in which speed or pas lvl both wheels or both controllers are , since you only use power and throttle of 1 controller

That's how I would do it since I want to draw low nominal voltage and amps from each individual cell anyway. Sure the controllers and thus the throttle might always be offering max power, but the battery won't be giving up too much at one time. Am I missing something obvious?
I love the way you illustrate your process
Nice way to get around the single motor rule. could you in theory also have several motors surrounding a central shaft like an old radial engine. 5 small motors producing a large combined power output.
This is fine in a straight line, but what about tight bends/corners? Is there any problem with the wheel speed difference? On the sand, the back wheel looked to be kicking out as it pushed against the front.
Is there any way to use generators to keep.your battery topped up while riding so one could go further and fast at the same time
Can you use two different size batteries and connect them independantly each motor (so dual mottor) and use one throttle to control dual motor system.
Watch this video and you’ll find the answer for your question 🤦♂️🤣🤣
Hi, I have the Walmart eride 29. Is there an easy way to add a front hub motor w thumb control? Use existing magnet pedal sensor and maybe a water bottle battery? For occasional hill boost?
I had a thought...what about the pedal assist? How would that fare with the ebike as well? Would it have to be all 3 wires to one controller, then the other controller just gets the signal, or would it be the same?
Great Work...... You are really filling a fast growing need for eBike info. I remember a couple of years ago when it was very difficult to get info/parts and now we are on the cusp of an eRevolution, Thanks so much for being a facilitator. . . . . . . . //// ?(1) avail of eBike hubs for small wheels (16" & 20")? . . .We ride recumbents and I look forward to adding ePower in next year or so. ( BikeE , Vision R40, Velotechnik Grasshopper ) //// ?(2) Can you charge a lithium too often? or should you let them run down before charging?
can I hook up a second motor up to a single power source
Tthank you for your simple explanation of the two motor integration. Very well done.
Sounds good but would it be better with pedal assist motor on there as well
The Motors you use look great and very discrete what motors are they? What's the best setup to build a discrete ebike?
I am wanting to do this to my ecotric sportcool fat tire bike you reviewed not to long ago. Would you be able to do a current video on making that bike dual motor?
Great video....very informative....what battery would you use to power both motors? You said use a bigger battery but what exactly? Thank you.
May be a good upgrade for mine some day and would probably just put a switch in to turn on 2x2 mode when I need it. Some kind of cruse control would be nice too.
Thank you Micah so much for this. I found a kit on Aliexpress for a dual set up for front and rear 500 watt Bafang motors. There is only one controller at 48 volts and 500 watts. I am trying to find the specs for the controller. Can one controller do the job? Is two 500 watts motors through one controller like a 1000 watt motor? A lot of newbie questions. Is this the best place for the questions?
how do you over voltage your motors? also how would you support your bike to handle higher powers. I want to take 2 1000watt hub motors and have both hooked up and over voltage but I'm not sure how to go about it and how to beef up my bike to handle the high power and high torque. thank you for your videos and insite
This is exactly what I need... Dual motor set up. Is it possible to add a 48V 1000 watt front wheel hub motor 26" x 4.0 fat tire bike? As my current ebike is 48V 500 watt rear motor with PAS. I find it difficult going up hills in my neighborhood, as I haul my two children in a Thule Coaster XT. Now, is it possible to add a conversion kit to the front? Can the front wheel also be connected to PAS as the rear wheel is already set up. I guess, id have two displays on my handle bar. What if I don't connect PAS, and only use thumb throttle only when I need the extra help going up the hills. I currently use PAS 2, and sometimes 5. So I guess it be nice to have PAS set up on the front hub, but now how do I go about connecting it to a pre-existing ebike setup. Any thoughts or ideas or sources that would help me accomplish this goal would be much appreciated.
As of today March 2018 we have very few ebikes in Manchester UK. I did your test and 10 out of 10 were pedal bikes. And that was on a major road leading into the city centre.
Hi, You will get a 2WD controller 36V/48V both. This controller got two wire for motor, one is back and one is for front and remaining everything is same as your normal kit. Try it!
I would like to know if you have used your bike on steep off road trails? I have two Honda trail 110's I love them but they loose traction on steep hills here in Montana. Would a two wheel drive bike have the low range power like the Honda has but wheel the traction of two wheel drive?
New to everything involveing e bikes, and I was wondering what the cheapest way to get a lithium battery that could get me at least 15 mile range is? Should I make my own or buy one, if I should buy, where should I buy one? And if I build, what's the cheapest way to make a reliable and safe battery pack?
Nice demo. What motors are you using?
These are Q100h motors.
Its said that these electric motors will still get moisture inside and eventually rust up and cause motor to go bad, for the amount of time you've used your bike have you ever opened up your motors to check the conditions of internals, or have you did an internal water proofing method.
My plan is to add a 3000w front hub motor to my current 1500w rear hub setup. I'll be adding a second 60v battery for the new motor and connect throttle to both controllers. See any issues here?
Stick two pedal assist controlled hub motors on a mid mounted e bike for a stealth triple motor machine.
So long as the hub motors are capable of freewheeling the operation of the original mid drive motor will be unchanged, but when you pedal the hub motors kick in for extra power and 2wd traction.
You can cruise around on the mid drive motor using minimal battery and power up steep hills with all three motors.
I am wanting to use two front electric hubs to build a electric car for my grandson, and I plant to make it look like an old ford 1920 model “t” I could definitely use help in what would work best. I am building it so he can grow up with it. For now Dad could ride him around until my grandson can handle it in his future.
Could you please describe E-Bike Hub Sizes. What bike frames are suitable for say Bafon Hub motors? What Frame measurements do you need for 4 Inch Fat Tires? What E-Hubs are required for 4inch fat tires? What measurements do E-Hubs require? Do they come in different size widths?
What are your thoughts on the uni pack power batteries? I just bought a 52v 13ah and so far it's great. I've built my own a few times with your help. Just wondering if you could do a video with one of there Chinese cell batteries. Seems very well built, but I'm no expert.
Hi. I like tinkering with things and I was wondering if this wiring diagram works for a mid drive and a rear hub with each drive system having its own battery. Or what else is needed. If this is in your book. Which one should I purchase. Thank you!
Do you have an opinion about using a generator (towed?) to supply power (like Chevrolet has done) with a small battery?
hey mika great videos by the way u have a great sense to speak to every type of person okay here is my quick question im sure u stay busy i got this 2000 watt 60V/64V 27A-32A Dual-mode controller thats has an electric racing car painted in the front of the box with Chinese letters & english words STRONG POWER ontop but the controller only has 1 set of all 3 yellow motor phase wires instead of blue, yellow & green so can u help me out with this im trying to put this on my small e bike with 2 48 volt 500 watt motors and my battery is a 12 in parallel 14 in series to give me 60 volts but how do i wire the both motors to the same controllers hall sensors
You didn't talk about charging the 2 motors can you cover that can you charge with one battery charger for both or or do you need 2 chargers
Thanks for. The video
Would it work if your front wheel has a direct drive motor instead of the hub motor ?
hi nice video i have an hub motor and gearless motor one has 9pins and the other has 8pins can they both work if two speed controller are conneccted im not using waterproof connector i have brushless speed controller. one speed controller has 6 hall sensor and the other speed controller has 5 hall sensor pins so i was wondering can it work
Yep your wiring diagram does look much more simpler.
Someday I hope to build an e-bike, I'm glad I found your channel!
Martin Taylor are you serious its like so simple
I think I need to use different motors for front and rear. How much more complicated?
What would you suggest for someone such as myself that has a recumbent with different sized wheels? I'm looking at possibly having a 250w on front 20", and a 500w on rear 26" (750w max here in Texas). Thinking have the 250w front on all the time, and just use the rear 500 for up hill boosts, or when I have a trailer to get a longer range on the battery. They would be on a cadence sensor instead of a throttle.
I love your videos, especially this one. Is it possible to modify a bike like the rad mini or the igo fat folding to a 2 wheel drive?
Hi, thank you. What are the issues of using hub motors of different power? Are there these issues even when limiting their speeds to the minimum of their maximum speeds? Thanks!
My dream bike: 2x2 full suspension 1000w fat E bike ... snow, sand, mud, uphill, downhill... no matter what!
High Power Cycle in Cali
I was looking at those, (1000w per wheel), and it would be $400 plus bike and whatever battery you wanted to use). To me, that seems very cheap. Since I'm not worried about weight on an E-bike since its going to be heavy (this wouldn't be like me replacing everything with carbon fiber on my road bike), I could just get a gently used fat bike for $150 (my cousin has one of those, we've thoroughly abused it, and it looks and rides like new, I don't plan on doing ledge drops like I typically do). Seems like $550 plus some high powered LiPo batteries (to keep it moderately light weight) should be able to rip around and have fun!
I kit built, from ebay a 48v x2 1000w fat tire bike..No suspension(with 4 inch tires- not really needed). Its awesome :)
@@jakegarrett8109 $199 48v 1000w front or rear. Slightly under size rim..still takes a 4" tire. Controllers are cheap- I upgraded 1 with pure sine which is about 25% better. $700 2 kits and a bike. $800 mid mount 48v 1000w. Rear rack mounted 48v 1500w. $1500 for a really nice toy :) www.ebay.com/itm/26-IN-48-Volt-1000W-Electric-Bike-Motor-Fat-Tire-Kit-Front-Wheel-US-Stock/132961352932?hash=item1ef51d3ce4:g:h-kAAOSwiuRcbqM~:rk:13:pf:0
One kit had a right hand throttle grip, second kit I used a thumb throttle on the left side(turbo). :)
Hello and thank you for your video.
Can you use the rear motor with cycle analyst for pedal assist and front motor for throttle only, by using 2 throttles and one cycle analysis. I am in the market for ebike and would love to start with something different
Thanks for your videos. Can I hook up 2 front hub wheel to a recumbent tadpole trike with an existing bafang mid drive? Wondering if the 2 front wheel need to be calibrated to spin at the same speed? Or a quad with 4 hub motor or 2 hub and mid drive combo?
Thks...you a lot bout volts, etc...bout how is the speed and how long would the batteries last
And how much would that cost
how do you manage with waterproofing ? or don't you ride in the rain.
Micah great vid. Other than the traction improvement (2wd) is having 2 motors more greedy on the battery front even if you lowered the amps draw. So does this reduce the range? Even as you say each motor helps the other motor out. So my question is 1 larger motor or 2 smaller motors?
What's the battery voltage and also amphours like is it a 48v battery with 20amphours and do you.connect both controllers into that , as ya shown ??
And also are you getting less distance having both motors to one battery or is this because you went with a smaller watt battery for the wheels ?? If you go higher for wheels connect controllers to battery less distance etc etc
And what's the average distance for this set up.you have awd both tires going qt once , like run time about 10 miles ?
Great information and thanks for sharing. The "all-wheel-drive" advantages are irrefutable - and must be GREAT FUN to ride! I can see where it would be very useful to have the option to readily switch/select either only FWD, or RWD, or AWD. Can you please show and explain how this could be readily optioned? With Thanks
Would having 2 motors, eliminate the need for gears? I want a commuter style bike for hilly roads and am considering dual motors
What size battery are you using and how many miles do you get per charge. How long does it take to charge your setup?
Hi thanks for all the great & helpful info. Q: can one controller runs two motors? If no, is there a two-motor controller out there?
hey nice videos, You inspired me to make my own diy eBike. As you mentioned in your video how often does the police stop an ebiker? I live in germany and we can only have 250w motor with out going into registration stuff.
I can only answer this question in terms of Israel, where I live. Here the police do operations about once or twice a year where they round up all the illegal ebikes they can find. So you're fine most days, but its a surprise when the next raid is. Having a giant black motor the size of a dinner plate is a dead giveaway for the police that your bike is illegal.
Wow. Where I live in the US, there are absolutely no restrictions on ebikes or bicycles. None. If it was originally manufactured as a bicycle, you can put a V8 on it, and you're fine, as long as you don't break any traffic laws. No registration, tags, insurance, etc on mopeds under 50cc either.
Can you attach both motors into one controller? Just splice or make a adapter with 2 plugs.
If you live in germany, do not get any motor that isn't labeled 250W. Just overvolt them, and you will be good.
In Germany, the Netherlands and some other EU-countries there are more limitations:
- throttle driven e-bikes are not considered bicycles
- the motor may only support speeds up to 25 km/h +/- 10%
- it should be peddle assist above 6 km/h
So why overvolt your e-bike? If you go faster than 35 km/h police will certainly get suspicious. I would say it is only useful to overvolt if you carry a lot of weight and still want to ride around 27 km/h.
Especially in Germany insurances can get nasty when you cause an accident with an illegal e-bike. They will claim you are not insured at all because you are technically riding a motorcycle which is not insured separately and you probably weren't wearing a helmet either.
Luv your content. Is there any scenario you see a mid drive motor added?
Can you make a video on how much voltage depends on speed and what voltage motor to use 24 or 36 also if I choose to use 24V motor and 10.2 Ah battery how will the range and speed affected. Please answer my question.
So if I run 2 controllers without Cycle Analyst , do I need to use two display,s to power the controllers on and use PAS please explain a little more can I run lights and brake lever motor cut offs ?
I want to be able to sync the wheel speeds of a front hub motor and mid drive motor on one bike for all wheel drive. I know it can be done and I came to you because I know you can solve it. Bafang M620 for the mid drive and 250w or 350w Bafang front hub. Thanks so much!
Can you run a hub motor in the front and a mid-motor the same way
I have only seen 3 ebikes in Orlando, but were looking to change that
I'm trying to setup my e bike to get to work but don't really want to use a lead acid battery. Would love to learn to build my own battery. The old batteries I have are lead acid but I'm not sure what to do.
I wondered if such a thing was possible, not that I'm going to do it, for now I'm quite happy with just a normal 1kw rear hub motor setup.
Ok legal and traction issues, perfectly clear but what about power efficiency ? I assume 2 geared motors must must be less efficient than 1 power equivalent gearless motor . Do you know any serious comparison between gear and gearless hubs ? thanks! great channel
