      Responsive throttle allows the bike to be powered without pedalling.


      With more kilowatt hours than any other bike of its class. We sourced the highest capacity cells in the world, the same ones used in the Tesla Model S for this. Charging time is 5 hours for the 13AH battery, and 6 hours for the 17AH battery.


      Packing 750W peak power, this workhorse is a serious performer. Using the bikes gears, it achieves optimum hill climbing, range, and speed. You can either use pedal assist or hit the throttle at 20mph. The throttle engages after the bike gets above 6mph speed.

      The California Standard

      Electric Bicycles are defined by the California Vehicle Code.

      New legislation became effective in January 2016. The current regulations define an “electric bicycle” as: a bicycle equipped with fully operable pedals and an electric motor of less than 750 watts, separated into three classes:

      1. A "class 1 electric bicycle,” or “low-speed pedal-assisted electric bicycle,” is a bicycle equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to provide assistance when the bicycle reaches the speed of 20 miles per hour.

      2. A "class 2 electric bicycle,” or “low-speed throttle-assisted electric bicycle,” is a bicycle equipped with a motor that may be used exclusively to propel the bicycle, and that is not capable of providing assistance when the bicycle reaches the speed of 20 miles per hour.

      3. A "class 3 electric bicycle,” or “speed pedal-assisted electric bicycle,” is a bicycle equipped with a motor that provides assistance only when the rider is pedaling, (no throttle) and that ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour and equipped with a speedometer.

      Local government ordinances are allowed to permit or ban any class of electric bicycles on dedicated bicycle paths and trails, with Class 1 & 2 permitted, and Class 3 banned, by default

      All our bikes come as standard with a 28mph motor limit making them Class 3. Adding a throttle to the standard bikes will make them illegal for public use in every state. We can configure bikes to comply with class 1, 2 or 3 though. Please send us an email for more details.

      Laws vary in different states / countries. Please check your local regulations. Here is a good resource of information in the US:
