Electric Folding - Series 5, S5 with Torque Sensor
The powerful BIRIA Electric Folding, Series 5, with upgraded battery, motor, and torque sensor. The torque sensor on Series 5 provides assistance based on the power you apply to the pedals. So the more power you apply, the faster you can go, and this will create a more natural riding experience.
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 (UL-2271 Certified), it has an average range of over 55 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. The S5 comes with a rear carrier, front basket, fenders, front and rear integrated lights, kickstand and a bell.
