Introducing the BIRIA Electric Step-Through Folding ST3.0-TREND The popular E-Folding ST3.0 has been upgraded with an addition of 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 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 wider 3" tires make your ride ultra smooth, and keeps the weight of the bike low, at only 57 lbs, one of the lighter weight step-through electric folding bikes in the market. The front and rear integrated lights allows you to see and be seen at night.  Fenders, rear rack and rack strap are also included in this model.
