Serfas Dart 500Wh Step Thru Electric Bike

White Theme

Looking to feel the assist? The Dart is speedy and powerful, right from the first pedal.

What we like about the Dart:

  • The 500W rear hub motor makes throttle and pedal assist takeoffs quick, which is great for getting out of hairy situations.
  • The 2.20" wide tires provide good traction and the adjustable stem and wide-swept handlebars give you a near fully upright seated position.
  • Sizing accommodates smaller riders.
