All Blix bikes can go up to 20mph using electric power. You may be able to go faster when pedaling hard or riding downhill.
Blix Bikes combine pedal assist and power-on-demand (throttle) electric assist. This means that you can have the motor boost your pedaling input, or just hit the throttle and go.
Classified as class 2 electric bikes, Blix Bikes can go anywhere a regular bike can and do not require any licensing in the United States.
