Reviews
Below are some critical reviews about EBIKELING Universal Torque Electric BicycleInstalled this on my bike according to ebikeling's video, made sure all the connections were tight - however, within half an hour of casual riding, the motor had proceeded to completely ignore the arm, rotate in the axle, and bent the dropouts on the front fork to the point of failure! Luckily, the wheel did not completely fail while I was riding it - as that is a dangerous situation going at 20-30 mph. But now my bike needs a new fork, which costs more than the price of not only this torque arm, but other models of torque arms that are better quality.In addition, after it failed, I discovered that the original designers of these torque arms, Grin Technologies... if you go to their website and go to their Torque Arm page... it mentions that this particular design of torque arm ("v1") was discovered to not work well enough to prevent high powered motors (as most cheap kits now are, between 500-1000w) from breaking dropouts. They no longer sell this version for that reason. Perhaps if you have a beefy steel fork, you'll be alright, but, then again, one has to consider if a price break is worth more or less than safety.
This torque arm is good insurance instead of having nothing at all, this will not hold up well if you use it with anything above 36v 1000watt as it is too thin, twist and breaks. If you are building an ebike 36v 500watts then this should be fine. I installed two on my wife’s DIY Ebike and it has held up fine. Given that she only has 36v 500watts. If you need something more durable, be ready to spend for something else.
Poor quality metal. The metal holding the axle bent within six months. Not recommended for 1000 W or above e bikes.
Below are some positive reviews about EBIKELING Universal Torque Electric Bicycle
Don't even think about using a front-wheel motor on a bike or trike without installing one of these. TWO, if possible. Without one of these, the torque of the motor will quite likely twist out the fork drop outs - the slot where the square axle rides. There are many demos and instructions that don't mention this. This is a good low-cost solution, but still needs some caution. The hose clamp can rip out. If your dimensions will allow it, you should replace these with a size that provides the maximum possible length of solid clamp strap and as little as possible length of slotted portion.
I am using this on my electric conversion for my trike. I figured out the mounting from looking at other pictures. Easy to install as i mounted it and the conversion wheel at same time. I made sure to have the disc brake mounted first before situating the torque arm. That way i have no problems and the fact that the motor can work properly without spinning the axle shaft is great for longevity of the conversion. I would definitely buy this product again.
I just assembled my ebike conversion front wheel 500w motor. The kit came with one torque arm and this one matches it. The bike has an aluminum frame so best to reinforce the front fork as best as can.
