It doesn't fit many bikes. Poor design and choice of details.

I bought 2 of these to mix front drive and rear drive eBikes. The hose clamp is too long for any bike and this is a very weak/cheap hose clamp. It won't take long, buy a good one, the right length. One set was missing a screw and a special washer. The screw provided is an unplated hex head, unlike what is shown in the picture. Most likely it will rust. You really need to make a steel band like you see on the coaster brake for this to work properly. Even if you put everything together, you might

Pros
  • High test results for grip and durability
Cons
  • Not all fit

Very durable and works great.

I installed one on each side of the fork on my dad's adult tricycle with a 250w motorbike. Oddly enough, his bike wasn't there. After about 3-4 months of use, the torque from their motor opened up the fork mount, allowing the shaft to rotate. I did a little research online and found these torque arms at Revain. The package was delivered quickly and was easy to install (after watching a YouTube video on how to install). Its forks use small diameter tubing and the clamp that comes with it is made

Pros
  • This is amazing
Cons
  • Not sure

Does NOT work - old, faulty torque arm design!

I fitted ebikeling to my bike from the video, made sure all the connections were tight - however after half an hour of leisurely riding the motor started to completely ignore the lever, spinning in the axle and the dropouts on the front wheel fork are bent to the point of failure! Luckily the wheel didn't break completely while riding as it's a dangerous situation at 20-30mph. But now my bike needs a new fork, which costs more than not just this torque arm, but other better quality torque arms.

Pros
  • Quality assembly
Cons
  • Negative is present
