A mechanical component is also integrated into the design of the best electric bike from HOTBIKE. Thus, the biker is able to approach bike parts mechanically rather than relying on electrical characteristics. Tektro 160 disc brakes are installed on both the front and rear of the adult bike. A 21-speed gear system on this adult bike makes it easy to climb hills and climb high mountains. This mechanical aspect is of great value to bikers who are unable to accommodate the electric element of cycling. These bikes are equally efficient and powerful. 36V 350W brushless motors are integrated into the rear wheels of the electric bike, not only providing comfort to the rider but also providing a number of additional benefits. The brushless motors allow the electric bike to achieve a maximum speed of 18 MPH (30 km/h). It employs a low sound strategy, which means it is somewhat environmentally friendly. A thumb throttle allows you to ride without pedaling at all! It is easy to start and stop the vehicle when using the throttle at any assist level. There are a total of five levels of pedal assistance.
