Kids bike Rebuild
Was the perfect fit. Was the right product to complete a rebuild on a child's bike. Has functioned exactly as it should.

A Shocking Bravo
I must admit I am fairly quite impressed. I was expecting something rather "lightweight" and almost flimsy, but just when it first arrived, I found myself holding what almost felt like it belonged on a lightweight motorcycle. The weight alone feels almost more like a small motorcycle sprocket, and installation is as basic as it gets (though, I was a bit of an idiot and forgot to put a washer on the hub, first, so, now, I have the blasted thing practically melded to the hub so tight that you can't even get it off without melting the hub with a torch - and yes, I mean that literally). A word to the seller:: make sure you keep that quality where it is, because it's rare to find, these days.

Great value, perfect part
The part works perfectly and is definitely an improvement from the prior one. With that being said, the fitting is really tight. I have not been able to screw it as far down as the original stock 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. Came pre-greased which is definitely a plus. Price was on point.

Perfect fit no issues
Easy to install fit the bike perfectly haven't had any issues since installing and the new part really makes the bike pop vs the slightly rusted one

Good sproket
Seems to be a quality freewheel at a fair price. I have bought several for ebike builds with no issues

Solid freewheel
Great to get more torque. You may need to change your chain, depending on how much slack you have.

junk
this is worst then the other cheapo crap amazon one i got this one is the 20 tooth and it is so bad the chain mover side to side when the wheel is spinning with the pedals sitting still this thing is like warped and wobbly oh and its a non removable too so yeah now will have to take it all apart to get it off it works ok but its trash no precision too it. oh and it was so over greased i think one of the clickers was sticking and made horrible noise and had to flush a brand new freewheel with oil.

Decent quality, bought to fit to a 250w motor to be used on a fafrees trike. No issues so far.

I like it, riding to work with this daily on my 2014 Norco Heart single speed bike and have had no issues so far. The hardest part of the process was getting my old freewheel off, I ended up having to take quite destructive measures. After that, the new one just threads on and you pedal away. Looks like this one can be removed with a traditional freewheel tool too if necessary. It's relatively quiet but has a satisfying tick and engages well. Very happy.

Nice. Converts one's bicycle into a single speed one. 5 stars.

Ce produit est conforme à sa description et j'en suis satisfait suite à son installation.

The sprocket was easy to install, has operated freely for the cycling season smooth as butter, and has nice level of freewheel noise. Neither too noisy or to quiet.
