Folding

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 55-60 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 in case you need to ride in areas where thorttles are prohibited. 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. The S5 is preset as a Class II ebike, with the pedal assist and throttle going to 20 mph. The rider can change the setting so that it can go up to 28 mph on the pedal assist mode (Class III).
