What makes this bike unique is that it has the appearance of a normal folding bike because the Lithium ion battery is hidden inside the frame. With a 500 Watt motor and 36V, 10.4 Amp Samsung battery, it has a range potential of 20-25 miles per charge. It has dual disc brakes with fat tires 20 x 4.0". A USB port is included to charge your phone while riding. This is a pedal-assist electric bike that also has a throttle, but the throttle can be easily disconnected and taken out in minutes.
