    • It’s fully functional and cheap
Color: 20T
With the caveat that this was for my 6 year old’s bike so it’s not experiencing huge levels of torque, it works well. I wanted to switch him from a coaster brake to a freewheel and this (along with a 20” wheel I happened to have) did the trick for cheap. Not too loud and the threads were fine out of the box. ... show more

Building another electric bike with my old 1,000 electric wheel I had stopped using this wheel because of broken spokes and not enough power sometimes going uphill. So I put it aside and bought a 1500 electric wheel. I'm using an old beach cruiser which I modified the crank and I just swapped over the old Tire that was pretty new off the original bike wheel but I couldn't pull the rear sprocket off didn't have the tool. Plus it was kind of cheap so I got this sprocket slipped right on got the wheel setup put it on the bike it works nicely there's a few other things I need to do to the electric bike to get it going before I can actually ride it and find out how good the sprocket works I actually had to spread out the rear Forks on the back of the bike to fit the electric wheel I'm glad this bike is still not aluminum I can't wait to ride this bike and see how good the sprocket works with the modified front sprockets. This sprocket's also bigger than the original so it might be a little bit easier to ride. ... show more
