DRIFT MANIAC E-Bike Freewheel 7 Speeds 11-28/11-34T Teeth EPOCH

The FW went on without an issue and with a slight adjustment, shift is accurate. I sprayed it with silicone and let it sit overnight and it is the perfect gearing for my needs.

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.

I read thru many reviews looking for an equivalent FW. Some had noted that the high 11 tooth sprocket is too fragile and if it breaks, the FW is unusable. This is partially correct, but the fragility is especially true if the higher gears are used to start or propel the bike a lower speeds. 11,12,and 13 tooth high gears are really for lighter bikes with riders who know how to use their gears and have developed a higher cadence for those gears. Riders who stay in these high gears tend to wear out the drive train components and their knees.E-bikes are heavier and initially faster then regular bikes. The lower gears of this FW are helpful to assist the motor in climbing or to ride the bike without battery power. The mid gears are good training for legs to practice higher cadence, get exercise and assist the motor; the higher gears allow you to keep up with the motor at higher speeds like from 18-30 mph and not ghost pedal. At 30 mph, I am able to use the 6th gear (13 th) as i have gotten my cadence up with practice.I live in a hilly area, and use & need the full range of my gears on alm ost every rdieWith the above in mind this FW properly used is excellent for an e bike, especially for general daily riding.

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!

I installed this on my V3 Ariel Rider Grizzly and it now works well. On my 3rd try it installed perfectly after I discovered a floating spacer from behind the factory installed free wheel and removed it. Someone should be telling the buyers about this hidden flaw or you may be getting a lot of returns from Grizzly owners. At this point I am now happy with my purchase and would buy again from this seller.
