Used to replace a Shimano MF-TZ21 7-speed Freewheel fitted to an e-bike
I've fixed up an older commuter eBike so that my partner can keep up with me on the road. Nothing too far, or busy roads, but some sections were far to steep for the motor and the single speed 14-28 to cope with compared to my 11-42 compact. This was the widest-ratio direct-replacement 7 speed freewheel I could find, but after fitting (which was rather difficult owing to the eBike wiring) and readjusting the rear mech, the bike shifts smoothly and has a much lower 'climbing gear' for some of those unavoidable steep sections. I haven't had much of a chance to see whether the 14 > 11 T change helps with the ebike's assisted top-end speed (it's an older model with no limiter), but I am happy with the purchase and suits the bike nicely. Solid construction, so hopefully it'll stand up to the rider+motor torques as advertised over time.

Great upgrade for my ebike
Bought this to replace the standard freewheel on my ebike. Easy to fit with correct tool and gives me better gearing for hills in low gear and better top speed in high gear

Top notch
Installed to a rear hub motored e-bike, not much to say other than in my case it works perfectly (11-34T version) Works brilliantly with my shimano altus system, and has increased my gear range. Very happy with the purchase.

A good replacement.
The freewheel 11- 34 fitted well to my ebike slight adjustment to go up and down gears gives me that extra top end on road.

Snapped after 2 weeks
Had my sprocket for just over 2 weeks, I was really happy when I first got it however, cycling up a steep hill today, moved to the top gear and it snapped off! Further inspection of the cogs also shows several teeth have worn away, after just 2 weeks. Bent my derailleur in the process, really disappointed as it’s the exact gearing I was looking for. Sadly it appears to be made of weak quality metal.

Outil de demontage absent
La cassette est compatible avec le Cyrusher Komoda 2.0, mais le produit est livré sans l'outil de démontage. Non conforme au descriptif !

Drift maniac 7-Speed Freewheel. Great wide-range gear-set.
Replacement for same-type unit that was damaged during removal for bearing-saddle repair. Great low-end, wide-range gear. Use on 38-yr old Schwinn, microShift 26 rear derailleur and microShift 7 speed paddle-shifter. Previous unit had 5.5k miles. Great value.

Getting the right gears right !
I ride two 20 inch folding bikes - one regular and one e-bike - both came with a stock 14-28 T 7 speed shimano rear freewheel. This 11-34 T is well constructed and arrived on-time and in good condition. Making the switch on both bikes offers an easy improvement - giving both a lower climb gear and also extends the top end gear for safer downhills. (no more frantic peddling just to keep up). A great purchase - Thanks
