Product Description

Fit well

7 speed freewheel 11-34t

This is a very good freewheel. I dont have an e-bike. I have a 7 speed fat tire bike. I was worried that this would not fit, but it was perfect.

E bike

Ebikefreewheel

My 250W e bike needed a bit of help on very steep hills the 34 teeth relly made it easy. The 11 teeth really made slower pedling going fast on the flat compared to 13 teeth & even worse 14 teeth. Great rear set for my E Bike

I have the 11/28T. Fits on samebike lo26 500W. Smooth shifting. No more 'pedalling air' at top speed.

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 on my RadExpand5. Easy to install. I initially got this freewheel due to when I was at top speed I couldn’t engage the gear.. now when I go top speed I can still feel resistance.. even got my bike up to 40km/hr. Also the climbing gear makes easy work of the steepest hills without having to put on full pedal assist.

Easy to install if you have the tool for it.Buy the removal tool from drift maniac. Totally worth it.

After 4000 km the chain stretch I replaced it and 7th Gear skipped. So I replaced the Freewheel with this one and it works perfectly.

It arrived with a notification. I forgot to order the tool with it so I have not put it on the bike yet...it functions properly by hand and seems like a solid unit. I will update when I put it on the bike.

For those reading this, believe what you want but the pictures speak for themselves.I had just installed this, got my derailleur fine tuned and shifting perfectly. Went out on a ride that I've done a million times on an OEM Shimano freewheel. First climb which isn't even that steep, I shifted into the 34T ring took two pedals (while still seated, and on 30 percent assist), and heard a snap and crack, and fell over into the gravel.Don't cheap out on important parts.

My only concern is it seems of less quality than what I removed off my e bike. The gears are quite a bit thinner.Huge improvement, night & day difference on my e bike. The 11tooth gear allows me to actually pedal assist above 25 mph and not just ghost pedal. Gained a couple mph on top end!
