 Don't Buy Surplus or Low-Cost Electric Bikes.

Many low-cost electric bikes are neither reliable nor safe, so purchasing one is frequently a gamble. They are not intended for long-term use due to poor craftsmanship or poorly executed electronics. Some low-cost fat tire bikes lack even the most basic electrical safety features, exposing the rider to electric shock. Furthermore, many surplus models cannot climb hills or provide an adequate level of pedal assist. They have insufficient power and cannot travel far. There is no way to get them serviced if something goes wrong. You can't rely on them. Finally, most are uncomfortable to use. Select safety and true performance. Choose only electric bike brands that have a long history in the market, as well as certifications.

Ted W.

I bought it for my New Year's gift several months ago and have cycled more than 1,000 miles since. It has a strong power system. But because of an accident problem, it was almost scrapped, the hub deformation and motor failed. I'm not used to the rest of my days without that Ebike. So I ordered another one just like it, and I'll take care of it definitely.

Frank Dudley

The bike was exactly what I had expected. Although I am 5'5 in, I had always wanted to ride a big bike. Before buying this bike, I specially consulted the customer service, customer service attitude is very good, told me in detail my height riding this bike without any problem, but when the bike stopped I need to tiptoe to the ground. I think there was no problem, as long as I could ride normally. I felt the customer service was very sincere and explained the objective situation to me. All in all, it was a great experience.

John Ferraro

I have bought this bike for 6 months, but there is an error code 10. The customer service patiently helped me find the problem and sent me a new controller. That's great.

Scott A.

I finally chose this one.Beautiful camouflage color. 1500W motor, 48V battery. Powerful!
After receiving as expected, perfect ebike! the shock absorption is great, very comfortable. I'm going to buy one for my son.

Kathy M.

The bike is a pleasure to ride. I have not had any problems with it and I am approaching 600 miles.
