Very nice bike. I've had it a few months and haven't had any issues. It charges well and rides well on trails through the woods. I use it for hunting and have enjoyed having it.

  • Love this bike!
Bought this for my husband who is over weight, diabetic and sedentary! I didn't want to spend $2k on a bike shop bike and just wanted to see if he'd give it a try. He is 71 and hasn't been on a bike of any kind in over 50 years! HE LOVES IT!!! Macho man even wears a helmet!! Pros: Easy to assemble, easy to ride! Cons: Haven't found one yet!! ... show more

  • Great Electric Bike
Color: Black Style: U8 Ultra-105+ Miles
Well-built and battery last longer than you can ride the bike (my seat gets tired). Only negative is there no operating instructions on how to efficiently utilize the bike, had to ride it for many miles to figure out best power settings and speed to maximize the battery. Recommend buy for sure!

Durability, size and very fun product. Power and speed are awesome. Easy assembly and good value for the money. We bought 2!!

  • Beast !
I bought two for my 14-year-old sons, who love this bike. Overall, they're very nice bikes, but too aggressive for me. What I don't like is when I turn on the assist, the bike goes 17 mph after four pedal strokes. It's practically impossible to ride slowly with the assist. If you want to go slowly, you'll have to use the throttle or not to use assist. Overall, the bike is beautiful, sturdy, and worth the money. Very powerful ! ... show more

  • Very satisfied with bike and customer service.
Color: Green Style: U8 Ultra-105+ Miles
I am 6'2", 220lbs. I live in a very hilly area. Older too. I wanted an ebike that could handle all that. This bike does! This motor does not struggle on the hills at all and the 18ah battery eliminates range anxiety. I did have a mechanical issue. Support was easy to contact very helpful. This is my first ebike and I'm impressed and hooked. ... show more

  • Headlight n fender slipping
So far so good!! It's a lot of fun! The only issue with assembly is the front fender and headlight will not tighten down correctly.

  • Great bike to own
The controller display is like much more expensive bikes. All bikes I've looked at have distance and trip readout and pedal assist. This bike has mileage in 1/10th of a mile which I like, plus Volume and Current readouts. This bike not only has 5 levels of pedal assistance shown with 5 bars, but it also has "real time" pedal assist shown separately which is great for preserving battery life. ... show more
