Helps with over peddling. Engwe l20 3.0 pro
Very good . As people say gets rid of over peddling. Fitted to a 2026 engwe l20 3.0 pro. Use the correct tool . Mine was on very tight was worried going to break wheel taking old one off but gave it some and it came off all good .there is a nut on the spindle near the big hole where you put the tool in don’t take that off the tool fits around it .

Easy fix for an annoying issue with my bike.
Sorted the ghost pedalling problem on my Engwe L20 3.0 Boost. It fitted easily using the Park tool FR 1.3 and the bonus was, I didn't even need to adjust the derailleur. Would recommend.

Just Brilliant. 34t-11t 7 speed sprocket
I do a lot of combined Off & On road Moutain Biking. When on the road sections down hill I need more speed but on my standard sprockets I'm maxed out. Wow what a difference the 11t & 13t sprockets make but still have the large 34t sprocket for those big hills . On the standard sprockets set's that only go down to 14t sprocket, my MTB used to get ahead of my leg. My bike goes faster than my legs can pedal on those big down hill sections (on road). Now I can drop down another 2 gears. I get so much more speed & I can keep powering down those hills without my bike over taking me. The hills by me generally run out before I do. Just a No brainer if you get maxed out for speed as I was.

Perfect upgrade for Ancheer bikes
Used to upgrade an ancheer e-bike. Combin d with the larger front wheel chain set I changed for a larger chain set this is a great combo and turns the ancheer sport into a great country lanes bike. No longer are my legs going too fast on the road. Fitted fine, just make sure you leave the washer that was behind the ancheer freewheel on when you add the new one. You’ll need to adjust your stops and indexing a bit but it’s easy enough to get it working.

Fits Hitway BK6 e-bike Perfectly!
My Hitway 7 speed ebike came with a 14 t to 28t Freewheel sprocket. The problem was the 14 tooth only allowed the pedals to be effective up to about 18km/h. An higher speed and my pedaling could not keep up to the assist. There are lots of sprockets available on Amazon but this is the only one that i could find that came equiped with 11 tooth to 28 tooth that would fit the Hitway motor on the rear wheel. It makes such a difference, I can now pedal up to 28 km/h with the pedals keeping up to the assist of the motor. I'm very happy about this! It only takes about 10 minutes to change but you do need to have the sprocket removal tool. Ordered separately on Amazon. Quality seems good but time will tell. I will update post if I run into any issues. At this point I definitely recommend this 11t-28t sprocket upgrade!

Works great, easy install
Works perfectly on my Rad Expand 5. I can now pedal over 20 mph with zero ghost pedaling! You also need the socket to remove the gear cassette. It's easy to install and made my rides far better. Love it.

Roue libre VTT DNP 7vitesses
Bonjour ,en remplacement d'une cassette 8 vitesses sur E-bike VTT MAX de chez Feu vert, cette cassette de même marque (DNP)mais en 7 vitesses s'installe parfaitement sur mon VTT. Cette roue libre se visse sur le corp de la jante sans aucun problème. Au moment de mon achat...6,30 euros...Prix défiant vraiment toute concurrence, je recommande cette article. Bonne journée et bonnes fêtes de fin d'années.
