Great product for the price
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!

Works with Lectric Step Thru 2.0
Got the 11-34t. Well made. Impressive features on the 34t sprocket to aid the chain to climb up this big gear. Installed on my Lectric ST 2.0 manufactured May 2021. Used Park Tool to remove old 14-28t. Chain has 118t and is plenty long enough to work with the derailleur. Needed to adjust the derailleur but that was easy to do using a Park Tool instructional video. Now I can pedal and apply torque at 20mph. Also like the 34t for takeoff and climbing. There is also improved spacing of mid-range gears.

Ease of Use
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.

Pretty good, but not great
What more could you expect for $32? For me this lasted just over a year with about 1400 miles on it through a BBSHD running 1700watts, I rode this thing hard and was pretty horrible about chain maintenance so when I checked my chain for wear, I noticed the cogs were pretty worn down too. I live in a very sandy environment so keeping my chain clean is next to impossible. All in all I am very happy with it, just ordered my second one. I love the extra large 34T cog, I can climb almost any hill with it. Maybe I’ll take better care of this one….no promises though.

Seems to work very well I got more pedal than I wasn't running out of pedal at higher speeds

Excellent gear range for a hub motor e-bike (11-32)
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.

The get there granny gear
I wanted a 'chips are down and the hill is tall' gear for my Lectric Xpedition and this is the one. Works a charm, simple swap.

Very poor quality
The media could not be loaded. I have purchased this twice in 2024 and had the same defect with both freewheels.After 2 and 4 months respectively, one of the gears started slipping, turning with the chain independent of the freewheel body and therefore not turning the bike wheel.See video.The fact that 2 of the same freewheel failed in the same way a similar amount of time suggests to me this is a production quality issue.
