Bike Saver!
The stock torque arm on my ebike was poor quality and causing damage that I did not notice for quite some time. The torque arm was becoming oval and the axel was spinning and becoming stripped out. I thought it was too late but took a chance on the V5, and I’m happy I did. This part saved my bike! I only wish I found it sooner. I’ll be buying a second one for my other ebike. Awesome product! Great quality! Highly recommend!

Sturdy and fits like it was made for my bike.
Very sturdy and adaptable design. This was installed on an Engwe M20.I like :-)

Super Effective. Worth the price premium.
I have an aluminum dropout, higher power(1500-2000W) Ebike that I was using the torque washers, AND 2 of the cheap Ebikeling torque arms on it, and the hardened axle of my bikes MXUS XF-19C (Ride1up LMTD version) absolutely shredded them when I went to a 52Volt 40A setup. I mean the bike is a brutal torque monster, 100NM, at 48V 25A, and at 52/40A I would venture to guess it's at 125nm, at least. So I slapped a V5 GRIN on bolted to the Rack Eyelet and put one of those cheapo ones on the freewheel side, with torque washers in the stock location... problem solved, I'm in the process of CAD/CAM capturing the removable derailleur hanger, and left dropout to CNC some 3mm stainless plates to PERMANENTLY fix the issue, but 11/10 I recommend these GRIN products, ALL of them work, and are very adaptable to almost any use scenario.

Great product. Great fit - Engwe M20
I found this torque arm to be really well made and a perfect fit for my e-bike. It's on the pricey side but not without it's reasons. The parts are made with very high quality steel and are cut to a high degree of precision. I recommend this Torque arm set to anyone looking to reinforce their e-bike's dropouts.

Quality product -- but expensive
Look like a quality product and much better than those that came with my ebike. One star deducted for unreasonably high price -- which, for some reason dropped by about 20% after I installed mine, though still way too pricy.

SOLID!
all the parts needed to complete the job. I was able to use the unused parts to fill the gaps of the e-bike upgrade kits was missing for my frame.

Total worth it
If you have a weird frame, couldn't fine a m12 kit anywhere or just don't want a hose clamp on your frame this is well worth it. Already toasted a motor by twisting the wire when it popped out of the frame. Worn out frame this is your answer, peace of mind w/e definitely cheaper than motor replacement
