Crew Dart20-S

The Crew Dart20-S takes the compact, bike-life-ready Dart20 platform and levels it up with more capability, comfort, and range. An 80mm travel suspension fork smooths out rough streets and adds control when the riding gets technical, while the integrated front plate gives the bike an aggressive, moto-inspired look.

A punchy 750W rear hub motor is paired with an upgraded 48V / 14Ah battery for longer rides and extended sessions. Hydraulic disc brakes provide confident stopping power, while fat Crew Blockster Tires, 20x 4.0" Front and 20 x 4.5" Rear, deliver plenty of grip and cushion. Finished with a powerful 48V headlight, the Dart20-S is built for cruising, wheelies, ride-outs, and everything in between.

Recommended for riders 4'10"–5'10".

CLASS-2 E-Bike Regulations

According to California Vehicle Code Section 312.5, a Class 2 electric bicycle is a low-speed throttle-assisted bicycle equipped with a motor that may propel the bicycle without pedaling but is not capable of providing motor assistance once the bicycle reaches 20 miles per hour. To qualify as an electric bicycle under California law, the motor must also have a maximum continuous rated power of no more than 750 watts.

This vehicle is categorized as a Class 2 electric bicycle for the following reasons:

  1. Throttle-Assisted Operation: The bicycle is equipped with a throttle that can propel the bicycle without the rider pedaling.
  2. 20 MPH Motor-Assistance Limit: Motor assistance is designed to stop providing propulsion once the bicycle reaches 20 miles per hour.
  3. 750-Watt Power Limit: The bicycle is equipped with an electric motor rated at no more than 750 watts.

These features allow the vehicle to be classified as a Class 2 electric bicycle rather than an off-highway electric vehicle, motorized bicycle, moped, or motorcycle, provided the bicycle remains in its original, compliant configuration.

Class 2 e-bikes are generally permitted anywhere conventional bicycles are allowed unless otherwise restricted by a local authority, property owner, park, trail system, or posted regulation. Riders are responsible for reviewing and following all applicable state and local laws before operating the bicycle.

All riding shown in our promotional materials is performed by experienced riders and professional stunt performers operating in controlled environments.

Fantastic Bike

I wasn't sure the suspension would make a big difference but it feels good. Only complaint is I wish it went above 20!
