Grin Technologies Universal REAR Ebike Torque Arm: Robust 1/4 inch Stainless Steel to Safeguard Ebikes from Axle Spinout Review

The design of the torque arm should allow it to be mounted on almost any frame. I installed them on our Catrike chairs which have very unique and bulky rear triangles. They are securely installed with minimal effort. Like all Grin Industries products, these torque arms are top notch.

I used old rim protection instead of the heat shrink that came with it. There was enough room for me to add my third collar. This is about the same amount of hard work you can do without changing bike frames. A must-have for electrical conversions, especially high-performance conversions to protect your dropouts.

After purchasing three sets of rear hub motors for three different frames. The brake rod solved my problem of axle slippage from cheap rear dropouts on the cheap Walmart bikes I keep buying. Your torsion bars should be included in all motor kits shipped from China, whether the bike needs them or not.

I was skeptical about buying this product because there are much cheaper alternatives, but when I received the package I knew I made the right choice! It's not a thin piece of aluminum, no - it's cold, hard steel. Installation was a little tricky for me because I already had a rear rack installed which saved me space, but I figured it out eventually. This is a one-time investment that you will not regret!
