*Great **Latest.Bike** . I upgraded the pedals, added fenders and installed a handle bar extension to raise them. Now it’s a pumped out E-Bike. I love it.*
Tabbed torque washers, Hardened steel double torque arms plus lock washers on every build.
One spin out 10 years ago and the motor repair taught me a lot.
Damn, where can i get those hardened steel torque arms, i guess not from china right?
real men don't use torque arms LOL .Can you say 1/2" thick dropouts.
I've been a tight nutter and survived that way for two+ years on my etrike before it started spinning out of the fork and ripping the phase leads. This looks like a great solution for front hub builds.
Awe man. Wonderful and informative videos !
I'm looking into going electric and I never realized the cons of regular wheels vs this quality e wheel you described. Thank you very much for your insight and shared experiences
I got their GMAC motor and am very happy with it. The All Axle motor looks really good if you prefer front wheel hub motors over rear wheel ones. Grin is an awesome company.
Is the GMAC a geared brushless and not DD? with a through axle/"all axle" system? I too have a fondness for the less appreciated front hub!
The GMAC 8T i had was very good performance wise. But it overheated quite quickly and it only lasted 6000km before it self-destructed (axle bends over time, causing internal parts to rub and pieces fall apart. Typical Chinese quality. Also condensation is a huge problem if you live in a place with cold temps. When I opened the mac it had a lot of water trapped inside. Also the spokes cracked because of the weight of the hub motor.
My dream bike has a mid-mounted direct drive hub motor that powers the rear wheel via an enclosed chain and only a single speed cog in the back.
Normal mid-drives eat a chain and a cassette every 300 miles...
Those motors look really cool. I'll have to check them out. I've built a couple ebikes using the more generic version that you're showing. All the ebikes I've built I've always done a double torque arm setup. I just don't see it practical to assume any other setup would hold up even short-term and especially long-term. It's good to see there's a better option out there. Thanks for the video!
Love wheels since I was 1, electric motors came right after that... best combo👍🏻😎👍🏻
Can you remeber loving wheels at one or did someone tell you after the fact?
@@trippleeksell4098 yeah i’m curious too
I really like bionx anti rotation locking nut seriously on of the best mechanisms I’ve witnessed for an anti rotation mech
Very comprehensive review and in-depth approach to your explanation! Good job.
The comments are very good. I had my experience with the Aston Rider ebike kit, it came out less than 300usd with lifepo battery and it has been running without problems since I had it more than a year ago
I must admit, I've had a bit of a fetish for motors myself since I was very young! 😁
I'm so glad your into e bikes. I always check your RC videos for great info I can trust. Now I'm building an ebike out of a Norco Shore and this is perfect. Except I want rear drive. Or maybe front and rear for muddy snowy conditions. ⚡⚡👍
Would love to see some videos of people actually using this motor to get an idea of how powerful it is. Looks really good!
Yup agreed
Years back I bought a Crystalyte motor from Grin and it runs with a 52V 18AH battery in a front axle configuration. The motor sits in a steel fork with two torque arms. So far I love it but I will upgrade to the all wheel motor in a rear axle config eventually.
A few years back crank motors where the best and easiest to install. Now they are not even mentioned.
the first 30 seconds had me banging my head on the wall XD
I mounted an Ebike with one of those kits and on my second ride, I got a bump on the road and the wheel stopped working. I had to push my bike 3 km to my house in the middle of the night. Not a cool thing.
This technology really needs to improve. I'm glad you guys are getting into it.
I have an off-the-shelf Juiced CCX and I'm pretty pleased with it- Bafang rear hub running 52v. I'm keen to do an eMTB build in the future, but I suspect I'll do a well sorted factory built one rather than keep sinking $ into experimenting! I want that sweet Specialized Mastermind system.
Finally found your channel, wow. You are very good on the tube, man. I always knew you would do well, you are a very tallented builder, proud of you JRH.
That's exactly what I could not find on the big 2 Internet sites. Thanks.
Good talk about weight and reaction torque issues. Not as much about the bearing and shaft which are also critical to me. My project is a quad bike which needs to fit through a 32" doorway. I like the Grin motor because it doesn't stick out past the tire (or looks that way). The quad needs a single side mount with a robust shaft which also cannot stick out past the tire on the outside. This video is 2 years old. I'd love to get an update where we are today and where the technology is going. Thanks for some really good info.
I need one 😀👍👍👍 thanks for the tutorial.
we recently had a problem putting motor because bike was thru-axel. thru-axle solution is great
That's a serious freaking hub motor! I'm getting it!
Great videp❤
I have been using my own torque arms for a few years. Easy to make your own using 9-12mm (depending on Adel size)box end wrench with a hose clamp and bolt.. Bolt goes throu round side of box end wrench. Open end of wrench goes on axle.. Hose clamp to frame or fork
I've certainly had a few bikes with wrenches for torque arms!
Interesting. I hope ti see a video on that. Thank you
Thank you for saving me all lot of money
I’ve been using Goldenmotor Magic Pie v5 and Edge Motor’s on all my builds. I’ve done 5 so far with the oldest built in 2016 still going strong. I like a super clean cockpit so the only thing on the bars is the thumb throttle. Since it’s throttle only I can use any brakes. Some bikes like the oldest uses no torque arms because the kickstand on one side and the derailleur on the other side are heavy steel and so far never had a problem even at 25amps with 52v battery peaking at 58.8v. Another MagicPie-V5 needs 2 Grintech v4 torque arms ir it will spin I the rear dropouts. The edge motors are smaller and have had years with no trouble and no torque arms in aluminum rear dropouts. All these have strong regen and are about $400 usd from Goldenmotor.ca or Goldenmotor.bike. I love that the controller is built into the wheel so I get the cleanest build that’s a regular bike with a throttle for whenever you feel like using it. These are commuter type bikes so nothing fancy. I’d love to build something crazy but the costs add up quickly. Love the videos!!!
where do u get ur batteries from
Hey man loved the video very informative. I'm working on a specialized big hit and was considering a mid motor pedal assist conversion, this vid came up and I'm considering a front motor now 😂 I need to replace the bottom bracket anyway though
Hi there.
I buy steel drop outs bolted to the aluminium frame working great for 2ys now.
Thanks.
Good video and I agree, Grin Tech Rocks :).
GMAC on a steel touring bike! 52v and it's a dream.
Lots of words and no specs. What kind of torque does it produce, what are the additional stresses it can handle? You mention it's a better design and they do scientific testing but where are the numbers to verify it?
Go to their website for full tech specs and on endless sphere forum for the testing information.
@@HolmesHobbies , that sounds like lots of junk-mail niggas luring me to store/website then not even booklet discloses watts, upper amp-temperature sturdiness-tolerance, nor production. So I will go to website and if headache to find current load, rpm, performance workload potential, and rain-puddle resistance durability , there I will tell them to stick it up their weely consumer-disservicing pig-in-a-poke junk-mail . Wino-Dope Rot for brains hyperbole-advertisers should do jail time for anti-information garbage littering. Switch to Recreational over-the-counter Non-alcoholic Marijuana !!!!!
All motors are generally the same it’s just a washing machine motor converted to run more effeciently and in a lighter workload
What you put in is what you get out with electric
HolmesHobbies Well I tried to use the link that you provided but it says it is a “no go” so can you provide a new updated link to their site please? Thank you.
Thank you this was extremely helpful. (First minute was annoying though)😊
The C3Strom Bike I own has no Spokes, just a Rim. Less noise and maintenance regardless of it being heavier. There are definite pros and Cons but I just wanted something Stable and worry free, rugged and reliable. I only wish the Brake pads lasted longer and were more robust.
I think there's so much room for new designs for Ebikes though. A dedicated Frame(bike) for that type of wheel wouldn't be too much to ask at all in my opinion. Even if it's just a matter of Sourcing Parts and Machining in a Batch Scale. Similar to what LunaCycles does. I'd buy all the Ebikes if I had the cash😝 Love it! The Video makes so much Sense in justifying design from what I can see and know about through my very limited experience. 👍😎🙏
Interesting stuff, thank you for sharing. I looked through the rest of your videos and couldn't find any follow up to downhill hubdrive bike? I'm interested in making an hub drive 24in mtb, any direction would be appreciated.
I like 2-strokes too. I once had a Japanese car that was a two-stroke that performed like an Aston Martin! Getting back to cyles : I want to do some extensive Touring on a Brompton folddown. Still in the Phase of deciding what, where and how; considering Regen Braking systems, thinking about Torque capacity of an E-bike motor for the Brompton and a whole lot more. I hope I can get a few hints and tips form this vlog, bearing in mind I am not young, have no smart sons who know everything, know nobody who can help BUT, I can learn reasonally fast, coming from a family where the men played with Engines.
I just converted a 26” Cannondale M700 frame with Pepperoni fork to a 500 w 36v front hub motor. I bought a torque arm but sent it back because I guess my nuts are tight enough. It’s racking up some hilly miles with no problems.
I’m running a front 9C motor on my conversion ebike. (44V hand assembled battery, old school mtb, 26 in wheels, 35A controller) I would have loved to get one of these Grin hubs but it was not in my budget. Your advice on a torque arm is good, I have two on my bike.
I've been building a 2wd Vector Typhoon based ebike with that hub in the front, phaserunner as its controller and Marzocchi Monster holding it. cant wait to use the bike (which is going to be VERY soon)
let me know if you want pics, great looking bike.
sounds lovely, i want pics! I'm new to all this and pleased i found John, thank you
@@MakeAllThingsBeautiful leave your email address and i'll send some
If you would please send me some pictures also and my email is: onetwoflush@yahoo.com Thanks!
me too. thanks. stepbrothers@gmail.com
Awesome stuff brother. 😇🌎💫
Great video with the needed details. The lighter weight GRIN hub = lower rotating mass and lower battery drain.
Although it's a new bike this year, eventually I will replace my E-CELLS Super Monarch Crown front and rear motors with Grin Tech hub motors and controller. That they are made in Canada makes it just that much nicer. My folding solar "blanket" is a Canadian made 220 watt Off Grid TREK to charge my BLUETTI AC200 MAX power station that charges my two E-CELLS batteries when I'm car camping/hunting.
Right on!
Thanks, looks a good refinement of a direct drive hub motor, I would prefer a geared hub, but I know this is not everyones preference.
grin also has a very nice direct drive (without freewheel) they have worked on. Can't have the all axle without a full planetary redesign they probably won't tool up for soon, but if you bug them too maybe it will happen. I would also prefer a geared motor but will take the resilience and efficiency of the all axle in the mean time.
@@HolmesHobbies as the comedian said: "You can't have everything...where would you put it?" The smoothness and quiet operation of a gearless (direct drive) hub motor is truly a wonderful thing...The inherent lower torque of these motors is only a downside when starting out from a stop or confronted with a sudden uphill grade change. But these two conditions only happen or make up a very, VERY small percentage of the total ride time.
For the quiet and smoothness I just LOVE my gearless/direct drive bike....if I'm bushwacking on dirt trails / single track I use my geared hub motored bike....face it, for EVERYTHING you need TWO bikes. It's as simple as that.
What are the advantages of the all axle over the gmac motor. Love your presentation.
the torque arm situation and reliability. The Gmac will have better torque density due to having gears. but gears can break and will wear out over time
A bit expensive, but the weight saving is very decent!
My trike have a Cromotor, 75V with a custom Dropout that was actually laced at Holmes hobbies! Regen is fairly insane on this one, it can even lock up the wheel.
Quite a few of my wheels out there! Good to see you coming through!
I'm running 48v 1000watt 30 amp bat powered front hub motor and engineering a drum brake also working on a belt driven mid drive to assist my 5 seater vip Pedicab. I'm very interested to learn all I can about this design and others as they could make my job fun. Please feel free to blow me up with information that can be helpful
Would you recommend waterproofing/waterresisting this motor?
How many watts is this motor rated for? Is is more powerful than a 3000w hub drive you can buy off of allibaba?
I was just reading about the Grin 'all-axle-hub-motor" last night, I have an old "Giant" frame that I converted over about12 years ago used a crystallite 407 in the rear wheel, worked ok when the SLA batteries would take a charge. The front suspension fork is an old "Judy Rock Shock" and I am thinking that if I can come up with the funds necessary, I should probably get a whole new package. The fork does have mounts for the disk calliper the rear brake is of course V-brake. It does seem that the folks at Grin have this motor nailed down, expensive yes but well worth it I figure.
I think Grin is a great company that is moving the ebike industry forward. I would like to see a smaller lower torque version of this motor for street or commuter bikes that run higher speeds and don’t need a ton of torque.
This
seen a video where someone tried making a sort of gearing for a DD motor where the windings are slowly moved away from the magnets which causes the magnets to rotate faster due to field weakening, it ended up producing nearly 2.5x the original speed but had 3x less torque
Thank u
Fantastic video I am looking for a recommendation, I am looking for a hub motor or and mid-drive. That will work on my Invacare top-end hand cycle. reverse is better
I have a 48 volt 500 watt hub motor mounted in the front wheel of my two wheeled recumbent, and yes I use a torque arm, and I've never had a problem.. But then again, since it is a Direct Drive/Magnetic motor, it does not spin up as fast as say a geared hub motor. On the plus side I have a maximum load limit of 600 pounds, and since I often pull a trailer, it works just fine for me. Oh, and my parents live on top of the second biggest hill in the city I live in. A one mile uphill grade. Okay, so its a good motor, but what is the voltage and what is the wattage? And what is the load limit?
The cheap hub motors from the typical 250 dollar kit with Me have always had an issue with the main wiring harness which consists of 9 wires turning and being damaged over time. What can keep that cable from spinning and twisting up?
i have a 12mm 135mm thru axle is there any motor for that size? cuz i oly saw 12*142mm motors. thanks cool video
Looking to use a hub motor on a trike for steadi cam work.
Need to be able to set the speed and also reverse the trike. Any suggestions ?
Hey John, I'm trying to electrify a recumbent Delta Trike, the Sun EZ-3 USX HD (two wheels in the back, one in front). It needs to be really fast in that I will be using it for BikeJoring (riding with the Dogs). Can you, or would you, put two of the rear hub motors on the trike or would you use the X1 Pro Gen 2 or Stealth? Of course, bikejoring (dryland mushing) is all done on dirt. Let me know your thoughts, thanks in advance.
I use a similar motor to run my house, comes from a washing machine. You know they make the best generators.
I live in San Francisco CA and I have the 2 motor and never have problem pedal assistant for hill for fucking great 👍🏽 no problem the motor is from ebikeling .! 💯👍🏽👌🙏
we are building bicycle trailers to explore the Baja outback. Our trailers will be powered with regen. The motor you are profiling looks perfect for us.
We could use your expertise.....
where in canada are you?
also is this what you would get for a electric scooter? specifically a dualtron.. i want to upgrade my motors for more power (i have it almost running on vesc now haha **almost)
I brought a moto tech 350 w 36v I had to change the front tire actually still the process little did I know the wires to the motor are now showing but seem to be fine ... my question is do I need a new Hub or is my motor still good?
I just purchased a hyper scorpion and I am having a lot of fun riding around LA. Looking forward to America made improvement for the cheap Chinese made parts.
Canadian. I just discovered them yesterday. Looking forward to paying them a visit after they re-open to walk-ins after COVID.
what do you think the possibility of integrating a nexus 3 speed hub into the middle of the hub?
I want this on my gotrax scooter. I can use some straps and some 2x4 wood (I don't have a welder and scrap metal).
I have been wondering why my ebike seems to lurch a little when starting off, it must be the slip fit torque arm not engaging tightly with the axle. Only 200 miles and the symtom has progressed. Great stuff.
Hay plez do a video of your mounting 2 or 3 motors on a bike I'm trying and I'm just lost I'm using a ancheer eb004 (city commuter )
You should re-consider your use of close-ups, and know the exact difference in the failure rates of the two types of torque transfers.
It's all documented on endless sphere forum, which has a better memory than I do. The raw numbers aren't so important IMO, except that this hub is proven far more reliable in terms of torque transfer. You can find the numbers if you want exacts.
Maybe not the best place to ask, I bought a Kickbike Cross Max 20D and was wanting to put a hub motor on the rear as I understand putting one of the suspension fork is frowned upon. Problem is, it's a strange hub width on the rear that is only about 72mm wide.
Is that a hub motor that is out there that would fit? I'm sure I can source it out to 75mm if needed.
I am still trying to figure out how to get a Grin wheel for my coaster brake flat track bikes. I have skip tooth sprockets on pedals and 115mm drop outs not cassette friendly. LOL! My CWC 1953 Roadmaster front drop outs have not distorted in 1000km and several 30kph speed bump hits. I will machine a brace now to strap to the fork leg, American steel way better than alloy.
Great video, very informative. The link says you've moved?
Nice video but.....question: how come you.ve opened a greentec motor but on the inside is only the rotor and the outer shell. However the Neodymium magnets are nowhere to be seen ?
do you know of an elec. 20" dia. front wheel that works with the standard 4" dropouts !!!
Thanks for the review, I see it this review was made a couple of years ago do you still feel the same about the hub? I'm considering building and e-bike and currently looking for a hub.
yes!
I got a new extreme bike Xtreme Trail maker 350watt 36vott 10mh love it i want a way better batt drive and comp
Thanks John! Random question: I have a 48V battery and a 48V controller. What would happen if I ran a 60V hub motor on this otherwise 48V system?
Typically it will just be slower. Much more fun to run a 48v hub on 60v. Or my more typical 36v hub on 48 to 72v.
@@HolmesHobbies Definitely sounds funner to overvolt than to undervolt! haha
@@HolmesHobbies ammm but in top of being slower I guess this going to generate more heat also, right? 🤔
Grin Tech is so innovative!
They are just like my taste.
QUESTION:
Have you guys ever thought about induction motor improvements?
This would take some more weight off a hub motor.
I am aware of the issues with torque at varying speeds, especially starting from zero, more current is drawn.
All of this can be compensated for with special Smart Controllers. Regen can be had from this as well through these controllers.
I know that there will still be tiny drawbacks because of current motor technology, using copper coils as the best known cost effective conductive material.
But because I have been following Grin Technologies recently, even email and talk with some of the guys there by phone; I am thinking that Grin Technologies can pull this off, or come very close to it, if anyone else is to do it. I think this would be wonderful!!
Also, have anyone ever thought about two wheel drive, so as to give e-bikes better balance?
So for eg. a 750W bike could use two 375W motor instead of just one heavy motor in the back, plus the riders weight and cargo, on the poor back wheel alone. Back tires are always the first to wear out by the way due to weight distribution.
For synchonosity, again, said special controllers would make this happen.
I hope that one day these Smart Inverter Controllers become standardised and affordable.
Thanks!
My understanding is that induction motors will be heavier than permanent magnet for the same torque density. Switched reluctance could be used though, but there aren't controllers for those easily available. There have been a few hubmotors made with induction, but they come at a weight penalty.
@@HolmesHobbies I'm not sure I fully understand though but I think that the same torques can be obtained from induction motors using said special controllers.
They will also be much lighter than PM motors. They might be less efficient, especially without said special controllers, compromising the range of the vehicle, even with special said controllers.
The setback comes from the current technology of conductors (copper).
But we will see when super conductors are fully worked out. Then induction motors might be of choice.
In the meantime, I was thinking that the innovative Grin Technologies could do a wheel but bearing the compromised range in mind; which shouldn't be all that far away from that obtained through PM motors.
I bet Tesla could do it! 😃 💜
@@moyettemorgan7102 It is the other way around. induction motors are heavier than PM motors for the same output or torque, and have lower efficiency. There is always recirculating current in the rotor of an induction motor, and due to this it cannot match PM motor efficiency and torque density.
maybe you are thinking of switched reluctance. That is a topology that could possibly replace PM, and have similar torque density and efficiency with lower manufacturing cost.
@@HolmesHobbies Yes. Thanks!
See I need brushing up. 😃💜 Happy
Let's do a cyclekart build with these!
That good best Projekt 👍👍👍👍👍🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻Is that water proof?Will it work for fat e bike?
Do the Hub Motors go on the front wheel?
sir, someone suggest, where can i buy good or moderate quality hub motors for tricycle in India or in the world. i need moderate price, good quality hub motors. i cant afford for grin tech and Heinzmann and cant buy chinees too.
You had me at 2-strokes.
i just read that 142mm have the same spacing than 135mm so a 142mm hub would fit in a 135mm is that true?
I have a mid drive bafang motor i use my own 84v controller what's a 72 volt battery i get it up to 110 kh but if i start at dead stop motor makes a whining noise and I have to Pedal and slowly put my finger on the throttle to get to go do you know why this happens I can't figure it out
110kh with a bafang midrive? That's not hapening post a video or you're lying.
can you show how to destrict hub motor speed sensor . i want more than 15.5mph. cheers
Great product 👍 Why are they only making front wheel motors?
Grin is the best!!!!
Simple!
i have a 3000w hub motor and i NEED torque arms i went to a laser shop and let them cut out custom torque arms 8mm stainless steel works perfect! and the nuts i tighten with a torque key to 40nm. but i would love to have a thru axle motor but i didnt find a 12*135mm motor only 12*142..
I'm pedaling a 29" bike equipped with full suspension and quick release axles. Does anyone have good recommendations for such a set-up? I stand 6'6" tall and weigh around 240 lbs.
Yupp.....Grin Technologies
would it be feasible to use a hub motor on rollerblads?
I have a Lectric 3.0 would one of these new motors work for my bike for extra power to climb Bay Area hills?
Possible, not easy. You will need to custom lace the wheel and find a place for all the components
@@HolmesHobbies Ok
Do you ever see something like this coming into RC? Whether it be directly on the wheels, directly driving the driveshafts like some TT setups almost do, etc?
Doesnt scale well. If we remove 35:1 gear reduction we will need 35x larger motor for the same torque.
@@johnrobholmes Makes sense. Just figured id ask. Always curious where the future of motors and RC will take us. :)
So I'm in the States and I have a worry that this may be the reason but I tried to activating the link and going to the website you suggested for these wheels, sorry hubs, and I got a non-existent page error.
Was the page just down or is there another reason why I couldn't access the web page?
Search for all axle hub. They launched a new website and likely didn't redirect. I'll look at updating the link
ebikes.ca/shop/electric-bicycle-parts/motors.html?motor_manufacturer=97
Considering the price I'm not sure who would want this other than someone wanting to do a trike conversion.
weight savings, more secure holding in the fork, no terrible torque arm to worry about. Lots of reasons to choose it.
HolmesHobbies he needs to make one for the rear hub ASAP.
@@nickibateson1466 You can bet they are working on it. Long engineering project to get it right!
I have a Coleman Bt200x minibike w an aftermarket engine and all the goodies but I want to go to electric. Think it’d be easy to use a normal brushless motor mounted where the standard gas engine is. A 6-10ish hp range and an output shaft large enough I can get a sprocket on for 40chain size. I’m probably asking too detailed and too much for a TH-cam video comment section lol. Unless someone makes a nice 8in rim hub motor where it accepts a 19x8x7 tire. And of course a controller and battery pack I’d need. Thanks if ya read this John.
Hub motor for a phat tire scooter I found planning a fat tire off road build www.amazon.com/dp/B07YHN3DW3/?coliid=I3N05Y8YSV9P06&colid=2QDXJJA81MKL1&psc=1&ref_=lv_ov_lig_dp_it
that fat tire scooter hub looks nice for an easy route. It won't be a straight forwards project. Head to endless-sphere.com for the best forum on projects.
How do these motors go for water resistance ?
First time viewer here. Great applicable information. I am interested in a high wattage motor for the purpose of speeds above 30 mph and torque for uphill. Does the motor you're showing provide what I need? If not, do you have a suggestion? Thank you.
not that simple! your weight, weight of vehicle, battery voltage and aerodynamics all add up to give you speed. no motor will get up 30mph if you weigh 500 lbs and make a 400 lb bike.
@@khandam7709 Nonetheless, where is a good starting point (motor and wattage), controller voltage, and battery Ah do I need to get my 175 pound body and bike to at least 40 mph via throttle?
@@rlbrett go to ebikes.ca and use their simulator. This hub will do 30mph no problem with the proper voltage and amperage.
@@rlbrett 40mph is very dangerous speed. car drivers do not anticipate you going that fast so big potential for accident. anything over 35mph can cause death in accident. wear a helmet

Go to www.ebikekits.com. I got the Heavy duty direct drive motor for my bike, laced into a 20 inch front wheel, I ride a recumbent. They also have geared hub motors. It all depends on how much weight you intend to put on the bike. A Geared hub motor has about a 300 pound load limit. Where as the Direct drive hub motor I use, has a 600 pound load limit.. Hope this helps.
@@longrider42 This domain if for sale??? No information here.
@@happycamper5900 Works for me, here it is again : www.ebikekit.com/
Try : www.ebikekit.com/. The motor and wheel and electronics package will cost a bit more, but the warranty and service are GREAT.
How do you feel about having to unlace the wheel to open the motor?
Not a worry for me. The sensors are most prone to failure on a DD hub, and they use high quality sensors and addressed strain relief. I'm not going into this expecting failure, the people at GrinTech are at the top of the industry.
@@HolmesHobbies They are nicely designed!
Nice features but I rather buy the standard hubs motor for the low cost. I could probably get 2 hubs for $700. I never had issues with the standard hubs. I’ll deal with the heavier weight and torquing the nuts every now and then. Thanks for the video though.
where do u buy ur motors and batteries from?
@@danhle1032
yes
I hope Grin makes a rear version of the All Axle.
