*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.

Love wheels since I was 1, electric motors came right after that... best combo👍🏻😎👍🏻

[LuisLabastida]

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.

I really like bionx anti rotation locking nut seriously on of the best mechanisms I’ve witnessed for an anti rotation mech

[ajemohaltom]

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.

the first 30 seconds had me banging my head on the wall XD

[skyeparker]

Would love to see some videos of people actually using this motor to get an idea of how powerful it is. Looks really good!

[shaunhall]

That's a serious freaking hub motor! I'm getting it!

[jerrygaber]

That's exactly what I could not find on the big 2 Internet sites. Thanks.

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

[MrBjoern]

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.

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!

I must admit, I've had a bit of a fetish for motors myself since I was very young! 😁

[grasshopper]

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.

[monicapatri]

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

[jordanpack]

GMAC on a steel touring bike! 52v and it's a dream.

[Zeioth]

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’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!!!

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
