Torque Arm & C Washers E-bike Electric Bicycle - Front or Rear- 2 Pack

Now if you knew that I had a steel front fork, and then a month beforehand, changed to an aluminum fork, and then put on a front hub motor, you may wonder what I was smoking. Let me explain. The steel fork had pretty much seized, it was 7 lbs, had only 30mm of travel left, and the dropout widths were very thin, maybe 4mm (9mm wide for the actual axle space, 4 mm wide looking at it from a perpendicular angle straight on). The aluminum fork's dropout widths are standard, more like 12 mm straight on. And unlike the old wives' tale, aluminum CAN be bent to a certain extent, which is important because the dropouts are 9mm and the front hub axle for e-bikes are 14mm. I did the switch to aluminum and bent/scraped the dropouts wider with a vise-grip wrench. Because my hub got tweaked to 1000 watts, I was taking no chances and bought two of these. And boy are these suckers on tight. And that is the drawback: if I get a flat out there, it's going to take two wrenches (one to hold the outside bolt, and one to unscrew the inside nut). So I'm not taking this hub off until I have to. But these arms work just fine. Oh and by the way, get a mid-drive instead (I didn't because I didn't find any local bike shop to do the installation/wiring until I already bought a front-hub drive).

Maybe I have too strong of a hub motor but these already warped one day after I installed them on a 500w rear hub motor. They didn't feel snug enough around the axle (supposed to be 10mm, but they are slightly more maybe?) and when the motor turned the axle actually compressed the metal and still slipped. I'm not sure what to do now but try another different set.

Lack of instructions, will scratch the crap out of your fork, doesnt fit the rear on 2 of my bikes. Expected a better quality and a better fitment for its price. Not worth the price if you cant fit half of it.

Secured and strengthened my brother's hub drive to the frame. The included Spacer prevented side rubbing of the hub.

The kit comes with ZERO instructions. There isn't even a picture of what it should look like when installed properly. Couldn't find a single tutorial on YouTube, either. They're all for different-looking kits. I have no idea if I even installed it properly.Also, the included clamps are junk. You can barely even tighten them without them stripping. Throw them away and get some proper ones.I'm going to attempt to get in touch with the manufacturer to see if they can provide some insight on the install process (and will update this review if they do), but in the meantime I would suggest looking for a better kit.

These are very needed for my recumbent bike when I added a 48v front hub motor. My forks would have broken without these. 48v is a lot of power. These did just the trick and I recommend them to anyone who adds an electric motor to your bike. Especially a front hub motor. Easy install, at least on one side. I had to cut and remarry the wiring to get it on the non-drive side.

Good product, no instructions so you need to investigate proper installation but this is a must have for any ebike conversion or your motor may twist itself off. Highly recommend. This kit has brackets for both sides not just one. - 1 star no instructions.

works as promised
