EBIKELING Universal Torque Arm Conversion Kits for Electric Bicycle, EBike Front or Rear Hub Motors and Mid Drive e-Bike Tool for Maintenance, 6 pc Ebike Accessories

I installed one on each side of the forks on my father's adult e-tricycle with 250w hub motor. Curiously, his bike did not come with them. After about 3-4 months of use, the torque from them motor opened the cradle end of the forks allowing the shaft to spin. I did a little internet research and found these torque arms on Amazon. Package was delivered quickly and was easy to install (after watching a YouTube video on installation). His forks use small diameter tubing and the provided clamp was made for fairly large tubing. So, I used two smaller clamps that I had in my garage. The larger ones would have worked, but I would have had to cut the excess length of strap from the clamp. Overall, I'm very satisfied and my father is pleased to be able to ride his bike around the park. At 92 years old, the motorized tricycle is a real blessing.

Very good

Works

Didn't use it at first and damaged my front drop outs and was about to danger my rear ones as well but with this on it's all good. No issues in over two months and 1000+ miles! Just make sure you find a good way to mount it so it won't move at all because with this torque arm it can be a bit tricky.Also I have a steel frame...if you have aluminum is recommend using these torque arms even for just 500w.....yeah....

kit comes with 2 cheap hose clamps for the front fork but nothing for the rear wheel stays so buy a good quality clamps if your using on the rear wheels. the provided clamps are to large for the rear. The brackets Are made Good BUT! the clamp are just cheap hose clamps i would not trust to keep my e-bike wheel on. i made my own from flat stock flat steel. stock hose clamps don't get it for me!

This item was required by E bike front hub assembly, it's a easy installation, price was cheap enough.

Look if you got a heavy bike/trike and are putting a beefy front hub in these are a must have. Prior to installing these applying full power would cause the hub to spin in the fork no matter how tight I made the bolts.I got super lucky it didn't damage my fork too much or shred the wires going into the hub otherwise I would have been out $700.These should come standard in front hub kits and every video on YouTube should recommend people install these.The clamps were a bit too large for my fork but that was easy to solve by getting smaller ones. While I think the clamp would have been strong enough I also put in steel straps the entire length of this part for added security so my hub would have to apply over 5,000lbs of force to break things now which it will never do and I never have to worry again
