IMHO it's invaluable to be able to service the hub motor. It's slightly more difficult than servicing a typical ICE starter, which is very easy to accomplish and it is slightly easier to service than the typical Alternator which isn't difficult at all but requires techniques which aren't initially intuitive ( brushes and springs). I'm not a bicycle mechanic or owner yet; so I really appreciate the share. 🤛👀🤜
I’m currently saving up for one of these for my bike, the real clincher was having a torque sensor built into the motor! It’s absolutely genius and once I save enough money for one, and figure out how to convert the axle on my cheap Chinese hub, I’ll be in heaven. ❤🎉
I want to thank you for this video that I was eagerly waiting for + respect to you for supporting the right to repair movement. I really appreciate it. As an owner of the Front Through Axle v2 motor, I will eventually need to replace the bearings, since my annual mileage is comparable to that of an average car user. I thought that when I reach 40-50k km, it would be time to change the bearings. Hearing that someone has ridden 100k km on a single set of bearings sounds incredible. My question is, what is the correct order for removing spokes from the rim? Right, left, or does it not matter to avoid damaging the rim? Best regards, Ebike enthusiast from Estonia.
Hey and glad to hear you've been making good use of the motor. For opening and servicing the motor, you actually only need to remove the spokes from one of the side plates (ie just half the total spokes). It really doesn't matter which side you take them from, but the handling is usually easier if the spokes and rim remain on the side plate that stays attached to the rotor ring. To play it safe you could go around and first loosen all the spokes by just a few turns before then loosening them the rest of the way to avoid putting the rim out of round during the detensioning process. But I don't think that's really necessary.
Thanks for this video, maybe I'll finally get around to replacing the smashed main cable on mine. So far it's being held together with liquid electrical tape, but who knows how long that will last.
Keep an eye on it but it's not broken and not causing problems there isn't usually a need to replace the whole harness if the source of the smashing has been removed. We've seen lots of cables with nicked/damaged insulation (but that weren't torn completely) which continued to serve for years and years.
Great video i have a s4 ev moped that keeps stopping you have to turn off and on lots of times to go again.sometime just stops on roundabouts which is scary and dangerous. Its a 1.4kw bosch rear motor.i was thinking maybe water has got in it as sometimes it only stops sometime then runs great other times lots and lots any info whould be helpful thanks danny.
Probably best to find a video related to this bosh rear motor system and ask for support there. We have zero familiarity with the system you are having issues with, but water ingress causing intermittent signal bridging on a controller circuit is for sure a possibility.
Hello, I have a 1000 watt Bafang motor from the front of an Arial grizzly 52V ebike. It is making a noise like a bee. It has everything new inside, the new bearings, the new clutch and it continues that noise like a bee. Can you shed light on that for me? noise?
It will stay on the rotor magnets primarily and not get lost. That said we usually wipe it all off preemtively with a paper towel and then apply new statorade just because otherwise you're likely to get it on your clothes during the rework process and that makes a stain you can never really get out.
Having to unlace your wheel to deal with getting into the motor is, imo, a big let down for a modern designed motor. It adds so much pain to servicing a motor down the line. I really hope there is a future revision of your motor series that mimics the pattern almost every other hub motor has with 3 piece separate side plate construction.
We agree it's a small annoyance, but suppose we did that design change and as a result the motor weighed 5kg instead of 4kg. Would you still be as interested?
@GrinTechnologies Would it be possible to instead of winning almost 1kg of weight to keep the current spoke design but allowing to add 1kg of materials in the stator to help for better performance (increase in peak torque, continuous power rating and higher saturation point for high power enthusiasts) ?
@@GrinTechnologies Yes, it wouldn't change my desire for the motor at all. (Sidenote, I put my money where my mouth is, I have one of these.) There's so much other amazing features in this motor that, even it came in at the *same* weight as other popular wide magnet motor options (mxus, qs, nbpower, etc) it would still be a better choice.
I think this version may have a lighter tone 😂 @zentechnician "You don't buy an ebike to pedal it" - wow, what a revelation! I see people cruising around on their ebikes without pedaling and think, "Good for them, they must have a handicap and are getting out of the house." But let's be real, most are just embracing their inner couch potato. Why not just get an electric motorcycle, deal with insurance, and ride the pegs all day? Unless, of course, you're a drinker who needs to hop from one watering hole to another to hang with the bar stool prophets. 😂 (Totally generalizing here, of course.) --- How does that sound?
Spoke holes through the side cover? Wow. That is truly stupid. Who had that bonehead idea.. When you are reinventing the wheel the idea is to improve it, not to make it a nightmare to work on. Unnecessarily overcomplicated. I'll stick with QSMotors. I've never owned a gear puller either. When the hub is in the rim you can just kneel in it to get it out. A 6" piece of pvc pipe makes a good hub motor stand and you just let gravity do nost of the work instead of using boards and a ginormous clamp that no normal person owns. Does the King of Canadia issue everyone Park Tools up there? Can we remember that people kill hall sensors and they need to be replaced? I'm afraid to even ask what you are charging for this thing that someone is going to be so excited to get but then becomes the bane of their existence when it gets a littke water in it. Ugh.
Everyone should own a gear puller, they're cheap and useful. I am not a big fan of spokes needing removal though, that seems painful to me too. That said all designs are compromises...
I think the spoke design change may be here to reduce weight of the overall motor. I agree it's a pain in the ahh to have to remove spokes for the disassembly but I wonder how much weight can be saved this way
@@nicod974 It's just nuts. They are giving you repair instructions but then they are making it too difficult for most people to do. That's just as bad if not worse than these companies that won't provide parts. It's under the guide of supporting right to repair but then cuts it off at the knees. What purpose is that serving to have spoke holes on the service plate. It makes my brain hurt. Like ow

Nice to see a oring to keep water out 👍
Those are cool green vertical torque drivers. What model are they?
Well done

If your motor has Statorade, do you need to reapply it after reasembly? Or will it stay on the magnets as long as you don't wipe it off?

I'm running a Amazon cheapy 48v . Just broke a axle at 44'000 miles . I ain't crying one bit i feel 44'000 miles for $250 was a great deal .
Yup, hub motors in general give an amazing cost / mile traveled, whether cheapo units or high end ones.

Hard disagree, you'll likely need to replace the rims before you need to service the motor on average lifespan of these motors.
can I convert my front all axle motor to a rear motor?
Kinda but that would require a new axle, new side plate, and new cabling job, and is not really in the scope of an at-home rebuild project.

I'm gonna have to charge extra money to repair it just because of the spokes removal. I won't recommend to buy this motor
