Are you wondering what the best eBike motor / drive unit is? In this video we'll seek to answer your questions about what electric bike motor is better for your application.
Our full guide here: www.electricbikejournal.com/e...
From cost to performance, hub and mid drive motors offer many benefits for different types of electric bikes. Although we favor mid drive motors for their natural pedaling characteristics and performance benefits for more aggressive terrain, hub drive motors have proven time and time again to make for some of the most enjoyable urban and commuter electric bikes we've ridden.
Hub drive motors come in two different forms, Geared and Gearless (or Direct Drive). They are located within the wheel, the motor rotates around the axle to apply the electric power. Hub motors use a Cadence sensor (Speed sensor) to measure how fast the wheel is spinning when applying the electric assist. Direct Drive hub motors are extremely durable and are great for offering high RPM's for high speeds. These motors are often found on Class 2 and Class 3 electric bikes, most of which come with a throttle to allow for easy electric assist. Geared hub motors have a series of gears within the hub and lower the RPM's to apply more torque. Geared hub motors may not achieve the same high speed outputs of gearless hub motors, but offer more torque allowing for getting up to speed more efficiently and quickly.
Mid drive motors are located in the middle of the bike mounted directly to the frame. Mid drive motors have many internal gears allowing for higher outputs of torque. The higher torque of mid drive motors has made them the favored drive unit for electric mountain bikes. Mid drive motors use a torque sensor to measure the amount of torque the rider is applying through the pedals then apply the electric assist through the chain ring. Mid drive motors are extremely efficient compared to hub motors due to being able to use the bikes gears on the rear wheel.
Both systems offer different benefits to electric bikes and both have value for specific types of riding.

Great video! You have got to love the simplicity of the hub drive systems, but I love the performance of a mid drive. It's been a while since I've ridden a hub drive motor, how close do you think they are to a mid drive in terms of control and performance?
Thanks, I would say that Mid Drive's are the status quo for control and performance. Which is why we exclusively see them on eMTB's. That being said, there are tech innovations in the last few years that have made hub drive systems more competitive in regards to natural pedaling feel, control, performance...
I have been a motorcycle owner and rider for years. Now do to people simply not caring about turning in front of
you and showing they come 1st. I gave that up, my wife’s very happy. I wrote that about the MokWheel months
ago and actually purchased the Magicycle Deer full suspension. She a heavy girl but built beautiful and has a lot
of power. I went with the Hub motor because of my background on motorcycles and having a throttle. Plus living
in New England we have lots a large hills. Being able to hit the throttle instead of have to start peddling was the
game changer for me. It’s funny as I have been wondering if I should have gotten a bike with Torque/ midrive
or hub. Just a week or so ago I met a couple who both had very expensive Mid drives. Both tried my Magicycle
Deer and both wanted to trade right there. Both of there bikes were around $6,500. I could see why his wife maybe
she’s got knee problems . But him I guess it really depends on what kind of riding and where you ride. My wife’s
using a Lectric 2.0 I ordered the shock seat post and gel seat will she ride more then around our Dead End my guess
no. Me I’m always ready and watching TH-cam on the new E bikes. Would enjoy your feedback…
I ride about 80km a day to work and back with a co-worker and his hub motor. I have a mid drive and it's night and day. My setup is 750W and 52V on a hybrid urban commuter.
@@ToddEdmondsonhi. I don’t own a bike yet but am looking. In what way are they night and day please?
@@ToddEdmondsonin what way is it night and day? And is there any scenario where you’d say a hub drive e-bike is better than a mid drive one ?
I own both a 750 watt geared rear hub drive and a 1000 watt mid-drive. The hub drive is simple and fun, super accessible for anyone, particularly non-cyclists. I live in a hilly area and the hub drive has done just fine, even on hills as steep as 16%, though I have to pedal to help on the steeper hills. The mid-drive is just a beast, it can make the 16% grade hill feel like it’s flat, but it requires you to work the gears and know how to work them. If you are new to cycling or consider yourself a casual rider a hub drive is probably best. If you need high performance and do lots of hill climbing, which means you are also probably an experienced cyclist, the mid-drive is probably best. Hub drives are generally less expensive too.
What bike uses a 1000 watt mid drive? That must be a torque monster.
@@cadriver2570A lot of people who do ebikes conversions go for +1000W motors.
What percentage gear ratio is fitted to the hub drive? Isn't it much less than the gear ratio used for mid-drive? Isn't that why it's harder to climb the hill?
Don't compare 750w to 1000w
My 1000w mid chews chains and the 160NM torque snapped the propriatary motor mount. Much higher maintenance than the hub motors.
Finally an honest comparison without "those are bad" .
One perk of the regenerative braking that he failed to mention is that is saves a good amount on brake pads.
That is something to note for direct drive hub motors. That being said, most brands have moved towards Geared hub motors or mid drive systems.
Excellent, informative video. Subscribed!
Everyone's case is different. For me: urban/suburban environment, mix of flat/hills, high winds. urban food delivery and long distance commuting. both bikes are converted single-speeds, use shimano nexus 3 internal hubs for gears. I have bafang 48v geared front hub and a BBS02 middrive, both setup as throttle only. As others have said, the hub is more direct, simpler, probably better for newer riders. But I find the hub less efficient for longer commuting and more noisy. The mid drive, you need to work the gears (I use 3 speed internal hubs, so it's easy), but once you get used to it, I think the mid drive uses less energy per km, once you get up to the higher gear, your motor is working less to help propel you. May work the chain/cogs more, but stock chains/cogs are cheap, I also use a single speed chain, there are no actual cog changes, so it is just not a factor. For me, the mid-drive is superior, I would not have said that the first couple of weeks as I was transitioning from a hub, but after 6 months, I do not like the front-hub any more.
The video I've been waiting to see!
sensible info with no waffle , thanks .
Great explanation and overview, thanks!
Glad it was helpful!
Great video!
The advantage of a mid-mounted motor is that it makes better use of the ebike's sporty attributes, and has higher torque than a rear hub motor at the same power value, making it more suitable for putting on a mountain bike. But the price is high.
Rear motors have the advantage of strong power output, but at a cost-effective price. The disadvantage is that it doesn't have the perfect torque like a mid-mounted motor, and is more suitable for use in urban commuting, or ebikes that don't require as high a level of sporting attributes.
According to our experience in selling ebikes, more users choose rear hub motors, the main reason is that this type of ebike is cheaper, the repair and maintenance cost is relatively low, but the power performance is also enough to cope with the daily use, but also to meet the common off-road activities on the ebike power needs.
Obviously for professional cycling sports enthusiasts, a mid-mounted motor is the best choice. And for regular commuter use, or those who don't require much in the way of sporty performance, a rear hub motor is the cost-effective option.
Sabe dizer se é possivel instalar um acelerador em um motor MIDI DRIVE ????? obrigado
The cool thing about hub drive is having AWD! My Vamoose Super Mammoth 500w has AWD it's so nice to have on a E-Fatbike because I can go up Icey hills easier and through deep snow with ease though I did overheat my motor a few times but in -20 it doesn't take long to cool off.
I've also been through ravine paths at at 20km/hr which is thrilling!
So both are equally just as good
Good to know
I honestly never thought about that lol
2 things I must point out:
A direct-drive hub motor is harder to pedal without assist
Some mid-drives have cadence sensors, such as the Bafang BBS02
Thanks, Direct drives can be more difficult to pedal for sure. Overall bike weight and limited gears are a major component to that as well. Great notes about the Bafang, most mid drive motors have many sensors beyond the torque sensor, including a cadence sensor. And as of recent, we're starting to see a few hub drive ebikes with torque sensors.
Excellent review explaining the difference between HUB and MID type motors.
Thanks! 👍
Thank you for the info I better understand
Thanks for your explanation.
Great info. I am just learning and disabled i wondering if they make mid drive trikes
That was a helpful breakdown, thank you
A good tip if you have those juliet connectors to the hub motor is to coat the pins with some dielectric grease. The reason is the plug can get warm and as it cools can form moisture on the pins leading to corrosion and eventual failure.
Excellent video and decision made - mid-drive. Do you have any views on converting a full suspension mountain bike to a comfy road going eBike? I am riding a front hub converted track bike right now and it is pretty minimalist. Looking to create something more plush for my 20 mile commute and I don't want to go down the fat frame fat tyre route.
Hub drives can be a drag; the motor makes the back end heavy; if you have a hard tail; then the bike hurts if you go over a bump unexpectedly! ouch; get a shocked seat post at least! The newer mid-drive motors from Bafang have a motor cut-out switch for 2022-23 models that will cut out motor power during shifts (amazing) and it works great. I have a Accomile Cola Bear with a 750w motor and it has the cut-out; there are never any issues with power on the chain, and the chain does not fall off due to power on during shifting. This motor is inexpensive compared to all the other motors out there, and a better design too; better than Bosch now! Forget belts, and forget the issues usually associated with Mid-drives. My Cola Bear climbs hills like a Bear; very fast.
Extremely well balanced video.
Much appreciated!
Very informative and balanced comparison. Thank you.
Question: if I purchase an eBike with dual hub motors (ie. each 750W), could I simply purchase new higher wattage hubs (ie. each 1000W), or mix (front: 750W, rear: 1000W), and if so, would batteries remain the same, just expect less life if using higher wattage hub motors?
Few months ago i was looking for an ebike, thought to get slightly used gravel with Fazua mid drive system. Made some research and found out that it is next to impossible to get spare parts for that system, though looks nice, one of the lightest ebike systems.
So just got a regular acoustic gravel. for my needs it's pretty good and already had a pretty long trip 140km in one direction, its like 280km in a weekend....
Maybe someday I'll get something electric, but not today.
this whole comment was just for you to talk about how far you biked. nothing to do with the video or ebikes lol
It;s really hard to decide which one is right for me when my budget is keep going up the more I do research,,,
Most reviews and comparisons are made under bike's spec itself only w/ wide open area either on flat or hills.
However, including myself, those who live in heavy traffic city dealing w/ cars, signals and bunch people each block that requires stopping and starting on a frequent basis, HUB-motor might be more suited w/ throttle combo unless you want to stress yourself shifting gear constantly.
But then again there is IGH which I'm new about
Brother I have an e bike named as Raymon hardray 4.0. It has a yamaha mid drive motor and a yamaha display. I tried to increase the speed of the bike by putting magnet to pedals and removing sensor from its original place.. it worked perfectly but suddenly it stopped working completely. It gives very little peddle assist. Before I could go max 16miles but now the motor doesn’t support 5 miles.
The change in the display that appears after this problem is that the range shown on the display is blinking. It never blinked before. Please help me. I haven’t found any video to solve this problem. No one in my area is able to identify the problem
The problem is for every great downhill pass you make, that means you have an uphill climb ahead of you. Unless, you get to the top of something like Pikes Peak. Have someone drive you to the top, and have a blast going downhill afterward. But I sure wouldn't want to pedal to the top of Pikes Peak. lol
I have both and I prefer the mid drive of the two
Loved the video
Thanks for watching!
Today was the first day that I was on an Ebike.. I tested out 3 different mid drive motors.. All with the carbon gates belt and all with the Invideo (not sure how to spell it) CVT hub.. All 3 bikes were totally different.. It was nice that I could drive them without any pedal assist and today it was 95 degrees.. I kept all of them at the lowest pedal assist and it was a hilly area and they did ok.. I think my speed was about 10 mph.. When it comes to mid drives I think I do want a carbon gates belt drive...
I should probably test out some hub drives.. I probably don't need the carbon gates belt drive.. I have never been a huge fan of chains.. I don't think I ever broke one but I have got them caught in my jeans and also have had them come off a lot of times.. That and I have had it where they don't go into gear.. Also, not a fan of the grease getting over everything..
Belt drive & hub gears are the way to go with mid drive motors, far less maintenance, mess, etc. Not cheap tho.
Bom dia... é possivel instalar um acelerador no sistema MID-DRIVE ?????
Im building a ebike for my wife and the platform is an existing mt bike that we have had for years. I had my mind set on getting the mid drive motor until i found out it doesnt have the throttle feature. Is there a mid drive motor that have throttle so my wife doesnt have to pedal at times ? :))
I think the best option is both, if I had the capital I would start building them that seems to be the logical answer
With the mid drive bikes do you have to be always pedalling to make the motor work?
I got a mid drive to fit this weekend, I'll be mostly using it for the roads to work and back, shopping, errands etc on a MTB with some flat gravel trails occasionally. One thing that's just hit me is that all the fast food delivery guys around here use hub motors. Wondering if I made the right choice now?
They use the hub motors because they're cheaper, because the companies don't pay them very well. They also use cheap ass batteries & chargers, which end up causing fires like as what happened in New York.
I am considering buying either a hub drive or mid drive motor to recover from injury but I live in a hilly area. I am looking at the Orbea D30 with the X35 hub motor or the specialized sl comp carbon with the Sl1.1 mid drive motor. I am 110kg and recently had a new knee and ankle fusion so would like to know which would get me up the hills easier until I get fitter. The hills I used to ride before my op were up to 20% on a typical 50 mile ride. I have heard that the hub drive will give up on you on steep hills as your effort slows but the mid drive will keep delivering is that true?
Both of those bikes are really great choices. As far as “giving up” goes a mid drive doesn’t show favor on flat or hills. It outputs power based off your input. Most hub motors will output based off the input of speed or throttle, but can’t tell the difference of hills vs flat and that’s where many will give up so to speak, with more resistance on the motor for climbing they have less sensors to compute the changes and output more power. That being said there are many high watt output hub motors that you can flick a throttle and it’ll power you up hills but that is a different cycling experience.
Thank you so much for getting back to me. It makes sense to me now about which to buy for recovery. I dont need a powerful embt just a road bike that will help up the hills round here. I dont want a motor to take over and I have enough power to keep up with a group but at 63 I am suffering up the hills more and more especially after my surgery. I have a good input so am going to test ride some mid drive motors of around 40NM or so. I think the SL 1.1 is 35NM so should give me just enough to get up most hills round here. I cant get out of the pedals so I have to rely on seated spinning until I am more flexible and things settle down abit more. I may not be able to as my ankle fusion is very restrictive and only flexes about 10% of what is used to but now I am pain free so we shall see. Thanks again. very much appreciated.@@ElectricBikeJournal
Im looking for more of an urban solution so I feel like hub drive might be more fitting however my area does have quite a fair bit of hills. Do you think a good hub drive system could still do fine up hill?
Rear hub drive bikes are fantastic solutions especially for urban use. When referring to mid drives being better for hills, the context is more relevant for mountain biking and dramatic elevation changes on rough terrain. We’ve ridden many hub system bikes that are great in hilly cities. A higher nM torque output of the motor will provide more consistent power for those hills, equally a geared bike as opposed to a single speed. We’d encourage going to your local bike shop to take a test ride on as many different bikes as you can. That’s ultimately the best way to find the right recipe you need.
I want to know the names of the fastest e-bikes with mid hub motors and with the most towing capacity and trike with rear hub motors??
Do either or both offer throttle only?
I need one
I have a question please.
Suppose if you were trying to decide on couriering. Such as delivering food or medicine in an urban setting. Which motor system do you prefer?
Thank you very much.
Ultimately both platforms will deliver the same result. We'd suggest searching for the style of bike you want (cargo, commuter, etc.) and lock in your price point. If hub drives are what is showing up, we'd encourage looking for one with a torque sensor as it will have a more natural pedaling feel.
Check out our review of the Ride1Up Roadster, its a great value, super lightweight, and could make a great courier rig with a rack.
@@ElectricBikeJournal thank you.
What Im curious about whether I chose a mid drive or a hub setup. What happens if the battery is dead or if their is a mechanical issue with the motor except the chain breaking. Am I still able to pedal?
With a dead battery both styles you’d be able to pedal around.
So... will a 500W hub motor w 60nm torque get up a hill faster and/or easier than say a 250 Watt Brose mid mount motor w 90nm torque?
If your after a very mantinence free engine the hub gear less hub is the one, personally never found geard engines to be any more or less efficient than a hub drive
The easiest way to compare is a hubdrive = automatic and middrive = stickshift, they both have their pros and cons.
❤thanks
You are welcome
Hub is cheaper but it's low torque mid drive are higher performance with higher torque it's good for hills so i prefer mid drive something from 750 watt with 48v and 17 to 20 A withh 200mm breaks
Would a mid drive urban bike be better for a hilly commuter route as opposed to a hub drive? Roughly 6 miles each way.
Exclusively speaking towards your commute, there great options available for both motor systems. Again if it is solely to be used as a commuter, consider things like: what accessories the bike comes with (fenders, lights, etc.), how much does the bike weigh (if you have to take it up and down any stairs), does it have storage options (rack or mounts to add one), and what is your max budget? Best of luck, let us know what you decide.
That sounds similar to my commute & mid drive definitely the best option for hills (I have a Bosch performance line 65nm which breezes up any hill). However mid drive means you don't have the option of using a throttle & is more expensive. Also, I live in the UK where throttles are illegal unless registered as a motor bike & occasionally the police round up & confiscate unregistered ebikes, so that another factor in my choice.
can one do a triple motor setup with 2x hub and 1x mid? What problems could one expect?
lift off
Bafang BBSHD Mid-Drive I will Never Ride another E-Bike in my LIFE for I Love my Bafang BBSHD Mid-Drive
I own both. I like the mid drive for hills and hub drives with torque sensor for level ground riding. If the hub drive chain breaks you still have the throttle as a back up. With a mid drive no such choice exists.
Alan,
Which bikes do you have. I only have experience with the Lectric 2.0 I think the MokWheel Crosia
is going to fit the bill. For going down to the barn for the horses and scooting around Bethany
Ct.
I was thinking of converting a BMX bike into an ebike would a mid or hub drive be better for BMX conversion
You should be carrying a few spare links. You can fix a chain in 5 minutes if you have the tool and you know what you’re doing.
and also how often does your chain break?
The midwives has more possibilities to fail, more hardware internally, plus all the pieces in the drive train, which has added stress due to the motor. Chains can be stressed more but derailures can get bent or broken. The hub motor has points of fail, but not as many and it doesn't add stress to the drive train. I do own both, plus a front drive I put on a recumbent.
What would be the advantages and/or disadvantages of a front hub motor with rear hub gears and a carbon belt?
I'm very interested in this config, but not a lot of manufacturers using it... 🤔
With just a front hub it becomes a throttle only( technically a motor bike) vs. a pedal assisted bicycle. Throttle only are not allowed on many (majority?) of bike paths. Also you would have less traction going uphill as the majority of the weight shifts to the rear wheel.
Not exactly. You can have Pedal Assist Sensors mounted to the crank. I have it. It works great. Also, front hub gives you all-wheel drive on a bicycle ;)
So what is it like if you have to change a tire or a tube on a hub drive?
Not much of a difference, about as easy as an old coaster brake cruiser.
We have a video here on the channel that talks about the process step by step. th-cam.com/video/_7cdlyyKtnY/w-d-xo.html
Great information as you folks know I’m trying to figure out what’s the best E Bike
for what I do. Having had experience with the Lectric bikes I definitely No this isn’t
what I want. Mid motor like you just said have a lot of plus’s . Yet so do the hub motor’s
I’m finding that because I live in a very rural town I enjoy 95% of my riding on pavement
I have gone over so many reviews. And I think I have almost decided on MokWheel
Basalt ( only problem is it’s pretty big ) I,m like 5’8” and 145 lbs. or Scoria which
Definitely will fit me a lot better. Both are hub drive with 90 nm which in Connecticut
we have hill over 20 plus degrees will most certainly power through them. Yet the
mid drives with torque sensors are a big plus. I,m driving my wife nuts but the more
I learn the better chance I will not make a mistake. Terrific review. Thanks….
I hear ya. When buying my first SLR camera a retired NBC studio camera man suggested I buy a little more than I think I need. He suggested this approach to not immediately outgrow the camera as I learned all its features. Like buying a PC or laptop the longer you wait the further behind you will be. So, give your wife a break, pull the trigger.
good to solve petrol problem and is ozone friendly
Ok, this is funny I have Bafang Mid Drives 750 and 1000 watt with a total of 23000 miles. The maintenance is torture, since the power comes from the main sprocket, the chain and your cassette will wear out every 1500 miles to 2000 miles. You'll not be able to interchange those parts, you will exchange both cassette and chain with new. Now your good for another 1.5 to 2k miles, I have about 100 feet of chain 20 worn out freewheels around here. If you buy a good hub motor kit, install it carefully, it should be care free to 30k miles I guess.
I just wanted to point out the exact same point. Mid drive motors really stress derailleur systems.
One big advantage of mid drive motors is that you can easily combine it with an internal gear hub. If you add a Gates belt you get a nearly maintenance free bike. If you want to avoid a derailer system with a hub drive you need some expensive and exotic stuff like the Pinion system.
I think you're handing out a myopic perspective of mid-drives. Not all mid-drive motors use a torque sensor. Not all mid-drives need "professional help" to perform much of the maintenance to keep them running. Not all ebikes require a proprietary frame that can only use one manufacturer's underpowered motor and small overpriced batteries. You mentioned the two types of hub motors but didn't mention add-on mid-drive motors like the BaFang BBSHD and their massive advantages... such as torque, throttle, adaptability, ease of installation and self-repair, cost, programmability, etc, etc, etc. There isn't a production mid-drive ebike I would own but I wouldn't ride anything *but* a mid-drive ebike.
Most mid-drive chain and drive train damage is due to what should be an ever-changing chain line from gear changing. Riders rely on the motor to grunt it out rather than downshifting. Coupling a mid-drive with a Rohloff Speedhub is a game changer. Absolute minimum drive train wear and fast sure gear changes with a straight chain line. The Gate's belt will be another game changer but it's a little more tricky with a full suspension ebike. With _minimum_ chain maintenance I change the chain and rear gear every 3K miles or about twice a year, less than $50 and I can do it on the side of the trail in about 45 minutes.
I've been riding the same ebike for over 8 years and have ridden over 48K miles. Much of that has been with panniers and pulling a trailer on rough uphill surfaces, and I have never had a "heat management" issue. Apply only the necessary torque to an IGH and the motor can always stay in its comfort zone. We're talking about ebikes, if someone rides an ebike like it's a little motorcycle they are going to have excess damage and stress the motors regardless of if it's a mid-drive or a hub motor... but mid-drives *are* superior to hub motors. - photos.app.goo.gl/ADgC6oyPM2gyrCq27
I agree with everything you say, and the new Bafang BBSHD motor is getting rave reviews and I never thought that I'd buy anything but a mid-drive, torque sensor Ebike but as someone with battery anxiety and motor failure paranoia I'm going to buy a Himiway Zebra hub drive bike, with torque sensor, as at least if the motor ever fails or I run out of battery then at least I can pedal back home.
I once tried pedalling a mid-drive bike without power and the drag put me off.
That was a few years ago though, maybe mid-drive motors have less drag now, and maybe I should stop being paranoid! 🤷♂️😂
This bike is only going to be used on old railway lines and very mild gravel, and to cover longer distances than I do on my clockwork bike.
Should I ever replace my full-suss MTB that I ride in the mountains then a mid-drive would be the only choice.
real question is which can you hack easier to overcome that shitty EU/UK 25km/h limit
Anything other than Bosch seems to be fairly easy to fool lol
anything except bosch system you can easily fool. these motors have so much power you can do atleast double.
Volspeed make a good chip for Bosch, reliable but only goes up to 27mph which is plenty really.
what if i combine them both together?
Go for it. Let us know how it works out.
please tell me you did this
Which gets you the most reliablility and least maintenance?
Can you ride a mid drive without pedaling it?
Thanks. 😊
Yes.
Mid drive bikes/kits come with either a twist grip or thumb throttle.
I just don't get the reasoning behind "you get to apply the torque to all of the gears with a mid drive." Because my hub drive gets the torque from all of the gears, too! With a mid drive, the motor torque combines with the leg torque. With a hub motor, the motor torque combines with the leg torque! I just test-rode an 80nm Bafang mid motor up a hill, and then test-rode a 100nm MXUS hub motor (with torque sensor) up the same hill. Guess what? The hub ebike climbed the hill with less effort than the mid drive ebike! Torque is torque.
Do motorcycles have their engines in their hubs? No. So why would anyone choose a hup drive motor? I have 3 mid drive bafangs. One a 750w and two 1kw. The 750 is my favorite and has a lot of torque and is smooth and i get more kilometers from a battery pack and i cam do rides using only level assist 3 while changing gears on tje rear cassette where as with a 1kw im using levels 6 to 9 to get up the same hills. I owned a front wheel hub motor which was 27.5". I rode 5 feet and it blew the hall sensors. Very annoyed and all i can say is i wont buy another one
It’s the cleanest form of drive. All is well that is round and rolls.
666th Like. rock on🚀
I pefer hub drive since you can use it if the chain breaks
Pretty rare to break a chain. But yes, hub drive can work without a chain, especially with the throttle.
If u like riding get a hub drive … if u prefer working on your bike get a mid drive …. Simple !!!
Which mid drive eBikes have you owned?
If you read the law, most hub drive motors are illegal, here in British Columbia, though enforcement usually doesn't happen if they are not operated in an illegal way. Most reputable bike shops do not sell hub drives.
you live in a very odd country. thats not a normal thing with hub motors for most countries
midhub engine are the most recent, hub motors old tech, cheap
Why not both?
Ok, I know why not both: it's expensive and not the best value for the money spent. It's heavy (two separate batteries!) and more maintenance is needed. The motors and controllers don't work together unless you have a specific configuration or are willing to do programing and/or wiring. Not all parts of the rear hub motor can be easily replaced with stronger parts to withstand the mid drive's force. All in all, probably best to go for a single stronger motor than to combine a mid and a hub.
I didn't do that. I started with a pre-built geared rear hub motor bike, then impulsively purchased a CYC photon and added it because it was slow going up the hills in the area I live in. Frankly, I love it. The hub motor handles slower navigation on pedestrian sidewalks and quick acceleration from standstills like a stop lights, while the mid drive punches it when I need to go fast to keep up with traffic or for extra force when I'm climbing those hills. The hub drive is on a rear-dropout torque sensor, so it senses the force from the mid-drive motor and continues to work when the mid drive is engaged (at least, if the power indicator from the hub motor display is true).
I definitely have to be careful with the force applied through the drive train: I already replace the chain and cassette with reinforced ones, but the aluminum freehub, the nylon gears in the hub motor, and that aluminum rear dropout torque sensor are all potential points of failure. I've been using bikes to commute for over a decade now though, so at least shifting gears up and down to minimize wear on the drive train is second nature. Any mistakes of leaving it in high gear at a stop are easily recovered from with the hub motor's throttle (side note: two throttles, a thumb one for the hub motor and a half-twist for the mid drive).
I definitely wouldn't recommend it if you don't have time and money in excess; I don't think most bike shops would do it for you, so it's something you'd have to do yourself, which you could easily get things wrong if you're an amateur (like me, who didn't even have all the tools needed to remove a bottom bracket or a cassette). Still, I've ridden it over 200 miles now and I absolutely love it.
If your hubdrive motor axle breaks you have to get a whole new motor
Likely more cost efficient at the least. Fortunately they are significantly more affordable then mid drive systems and much easier to replace.
Shouldn't hub drive motors be more efficient by defintion? You have loss when tranferring power via a chain, you don't have these losses with a hub drive...
I think it would be safe to agree that as a motor using throttle only a hub would be more efficient for the rider. However, as a bicycle and pedalling a mid drive would be more efficient since you can utilize the gears of the bikes drivetrain to change the gearing ratio. This would make the power output of the motor more efficient under load, like climbing steep hills. I guess a close example would be using 4 Low on a 4wd vehicle, the different gearing ratio is able to maximize the output of power to the same wheels.
no
Mid drive is too much for a chain and derailleur setup in my opinion. I would only go mid drive on a full suspension bike because of the weight distribution and suspension efficiency.
I am 5'8" and felt the medium fit me great.
Do you use your E-MTB for HUNTING or backcountry CAMPING? Then you need a hub motor (or in my E-CELLS bike's case two hub motors) Say a chain breaks with a mid drive motor. Say despite your tools and chain repair parts you CAN'T repair it. What then?? A long push back to the parking lot. But with hub motors "no chain is no problem". Besides mid motors drive THROUGH the chain so they wear it much more quickly than pedal assist power using hub motors, raising the incidence of chain failure.
For 99 percent of the time a hub motor is fine if you ride mountain biking in single track a mid drive is best . I have a hub drive with 100 nm of torque and it's fast and powerful if i have to hill climb i turn on the front motor and it climbs great. Ill ride all day in 7th gear and never have to change gears you can't do that on a mid drive . And lastly my dual motor 60 volt 20 amp hr 30 + mile an hour bike costs less than most mid drive bikes . I positively don't want a mid drive
If you have access to many ebikes, I suggest you design experiments to back up some claims in this video. At least to satisfy your own curiosity.
For example claims about efficiency and torque/ climbing being better in mid drives. They can pretty much be in the style of car MPG tests. Ride similar routes at similar speeds and count how many Wh it takes to fill up again.
I feel that your conclusions are more based on cheaper hub drive bikes vs premium mid drive bikes.
Food for thought: A direct drive hub motor can be designed to produce so much torque that it would taco the bike frame instantly. Electric motors can be designed for any load conditions and bicycle load conditions are not so difficult to design for.
My $100 Chinese direct drive hub motor can produce so much torque that in an MTB frame, the bike flips over. Sure the motor will also get hot, but it CAN produce the torque.
Any gearing or use of multiple gears is a sign of a undersized or poorly designed motor.
Think if massive trains. They travel from 0 to 100s of miles per hour with one gear and with massive loads. A bike would be trivial to design for.
All very valid and great points thanks. Most of what we addressed focuses on the higher margin of what someone is most likely to come upon as they shop for a bike. As most mid drive bikes are supported by premium brands and most hub drive bikes are coming from less premium brands. Each drive type has an ideal environment that they perform best in.
This video and our platform is focused on the general audience and specifically people that are looking to learn. Thanks for the input and we'd love to see that wheelie machine.
@@ElectricBikeJournal Not my video but same $100 hub motor: th-cam.com/video/e03rMDmJzLE/w-d-xo.html
Your $100 motor is NOT that powerful lmao. Why would you bother lying about something so easily verifiable? If you said $1000 I’d believe you
Chain drives and derailleurs are obsolete.
Hmm, intersting. Why do you think that?
Because derailleurs were designed for puny humans, as were cassettes/freewheels. The link glide system is better - but it is still just an attempt to make a powerful motor mesh with a drivetrain that has not really changed in decades. Ebikes are about where cars were in 81. They are still just transitional forms. I will get a Moustache with an enviolo CVT and a belt this week. My old RIZE MD started to shred my freewheel almost right away. (in the vid I call it a cassette, that's wrong) I am on my 3rd freewheel now after only 1600k. And I know how to shift. I have been riding for sixty years continuously.
Chains and derailleurs are still only around as people as both manufacturers and riders are familiar with them, and to be fair, they do work "okay" with lower torque motors and rear wheel drives. I love forward to never indexing a derailleur again.
Great vid. Thanks!

90-95% of ebikes are chain drives, so this is a false statement
Too much hand motion is annoying for someone who is autistic. Other than that fact I enjoyed this informative video.
lmao I'm autistic and didn't mind. Spectrum bro.
They're both poorly designed.
nah
Mid drive is made for bike shops, hub drive is made for ebike users.
most of the ebikes in shops are hub drives, so this is false
