Introducing the new powerful BIRIA Electric Folding, Series 4, with upgraded battery, motor, and suspension fork. Has the appearance of a normal folding bike with the Lithium ion battery hidden inside the frame. You can fold up the bike and fit it in your trunk, or your closet. With a 750 Watt (950 Peak) motor and 48V, 14 Amp LG battery, it has an average range of over 40 miles per charge with pedal assist. It has dual Tektro hydraulic disc brakes with fat tires 20 x 4 1/4 and color display. This is a pedal-assist electric bike that also has a throttle, but the throttle can be easily disconnected and taken out in minutes. The upgraded front suspension fork will allow you to handle any terrain, from off-road to the city. This is an upgraded version for the Series 3 Efolding, and other than the hydraulic disc brakes, color display and CST tires, it's identical to the S3.
