It was easy to install and makes a nice sound while coasting.

  • 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

  • Nice sprocket
Color: 18T
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

  • Have to use a 1/8th single speed chain with the 20 tooth freewheel!
Color: 20T
The existing drive train accommodated a 3/32nds wide 5-8 speed chain, but the 20 tooth freewheel is too wide, and I had to swap it for a 1/8th single speed chain.

  • Tens of thousands of miles!
Color: 16T
Pre-service with "wet" lube (as opposed to "dry" lube or "cleaning" lube) and it will buzz for years. I wore the teeth to hooks and got another one. Great investment.
