2 Sets Universal Torque Arm Conversion Kit Compatible with E-Bike Front or Rear Hub Motor Installations,Electric Bicycle Maintenance Tool

Worked exactly as I expected! I can't believe I solved the problem for less than 20 bucks. It's such a great find. Thanks a lot for this invention! For anyone wondering about compatibility, I used it with my Heybike Brawn e-bike, and it worked perfectly.

The axle on my electric bike would spin, unplugging the wires, and this product absolutely eliminated the problem. They are nicely made, fit perfectly. are easy to install and look great! I even bought two, one for each side.

Rear hub wheel on e-bike fell off twice, thankfully not while riding, which would have been disastrousOn examination, the drop outs were rounded out and lock washers were worn, allowing axle rotation and looseningI didn’t trust myself to install, so took it to a bike shop, maybe it’s overkill but had it installed on both sides of the wheelThe torque arm is very solid, manufacturer states it is stainless steel, the screw to attach to the curved arm is very bulky with a wide head, we had to substitute with a flat head screw to allow close fitting to the frame, thus 4 starsOtherwise install was straight forward, avoid drilling into the bike frameI never ever want the rear wheel coming off during a ride , electric motors create enormous torque on the drop outs , go ahead, spend the money, fit these, it should add peace of mind

Being an old BMX at 50 years old, I knew there had to be a solution to my slipping wheel in my aluminum framed Rattan challenger I have 1600 miles on and loved every bit of riding it EVERYWHERE, from doing errands or doing grocery runs, or removing the basket and jumping and going trail riding. And for my third tire change the back axle kept slipping and slipping for a few days and I about gave up but I looked online and heard about torsion arms, which I knew would work like coaster brakes had a similar bended plate of steel holding the hub and bolting the steel plate on the bike frame. When I did finally receive the torsion arms, it took a couple minutes to find the best way to assemble them against my frame and as you can see, it cleared so perfectly from the shifter and the main bolt and I found a place right by the rear dropouts. Wish I had them when the ebike was new, my next one will get one as a assemble it, and I will buy this again. I'm DEFINTELY going to look for cooler looking clamps, lol. A big problem with shipping but that was it really their fault. I just needed this item on October 10th so bad because my E bike is my only transportation.

Good quality but they don't fit. I have three ebikes (all diferent brands) and they all have 12mm axles. These torque arms are described as "universal" and "the size of the motor shaft should be LESS THAN 14mm" and specifically for ebikes. They are too sloppy on a common 12mm axle to do what they are intended to do.

Works good with the Amyet S8.

does not fit Freesky Warrior Pro E-Bike.

This saved me from a 1000$ repair issue. My frame dropouts for the rear wheel with the motor, were almost fully stripped . I thought it was game over because when I hit the motor it would spin inside the frame and since the cable was also in the axle it would get sucked in and crushed. After buying this it completely solved my problem. I’m not paid to say this but I think this is something everyone should buy because it saved me from paying almost a full 1k for a new frame and motor for my RadRover6
