    • It works great!
Very durable, nice and quiet, and will work with e-bikes. Swapped out the cassette freewheel to this single speed and boom I have a converted mtn e-bike to a single speed e-bike.

    • It would be a bargain at twice the price!
Color: Black/Silver Size: 18T
Needed a little more gear cause to climb some inclines comfortably so I purchased the 18T freewheel. I was pleasantly surprised at the quality of this very inexpensive freewheel. Smooth, quiet and neat looking.

    • It does exactly what it is meant to do
Color: Black Size: 18T
It was very easy. I bought this and I bought a new rim. Of course a threaded rim. Anyway this freewheel screws right on the new rim so easily just have a matching freewheel removal tool for removal if needed. This thing went right on and spins nice and easy and true to its name it spins free when pedaling backwards. ... show more

    • Great value, perfect part
Color: Black/Silver Size: 16T
I put roughly 125 to 130 miles a week on my electric bike just riding to and from work, and doesn't include any leisure activities. So I wear out the parts on my bike pretty quickly. I am updating my review to reflect the fact I bought another one these freewheels, and not because it's poor quality or doesn't work, but because I wore this out too! The part works perfectly and is definitely an improvement from the original stock OEM freewheel. With that being said, the fitting is really tight. I have not been able to screw it as far down as the original part (I was able to screw it on about 3/4 of the way down perhaps more), but there is still enough clearance between the frame and the freewheel that it doesn't cause a problem. Had trouble finding a freewheel tool that had a pass-through big enough for the axle on my bike. Came pre-greased which is definitely a plus. Price was on point. ... show more

I rarely leave reviews but this one is a must. Freewheel does what it’s supposed to do. BUT It’s so out of round and sounds junky. It’s for my 75 schwinn klunker build. Pedal around the neighborhood no brakes fun bike. Perfect for this even though the chain goes from snug to loose because of the freewheel being cheap Ave out of true. I have profile cranks and a Rennen 40.8 race sprocket on there. So it’s not that. Everything was smooth when I had my ACS claws 18t. So buy this if you’re just needing a different gear for your chill bike. Don’t put this on your race bike or freestyle or anything you care about dearly or plan to pedal hard lol ... show more
