Introducing the BIRIA Electric Step-Through Folding ST4.0 

Introducing the new E-Folding ST4.0 with an upgraded suspension fork, larger battery, and a torque sensor, where the assistance provided is based on the pedaling force being applied.  So the harder you pedal, the more assistance you will obtain.  This creates a more natural riding experience.  It features a 500 Watt motor, and a 48V 13 amp battery, and has the power to get you up the hills with pedal assist or the use of the throttle, whichever you prefer.  The 3" tires make your ride ultra smooth. The front and rear integrated lights allows you to see and be seen at night.  Fenders, front and rear racks are also included in this model.
