Motor Controls and Operation

All bikes by Rad Power Bikes in North America are equipped with two ways for a rider to obtain power assistance from the motor: a twist-grip throttle and a pedal assist system. You can use either system to control the level of assistance provided by the electric motor!

The throttle is located on the right side of the handlebar and can be used to propel the bike forward without pedaling. 

On models released in 2020, the throttle is active when the bike is on. The throttle is engaged by slowly and carefully rotating it toward the rider. Once the throttle is released, the power assistance from the motor is cut off and the throttle no longer propels the bike forward. Always keep one hand on the brake lever and be prepared to squeeze the lever to disengage the throttle if needed, or turn off the bike to prevent accidental throttle engagement.

Note: On models released in 2019 and earlier, the throttle has a throttle power switch (a black button to the left of the twist mechanism). When this button has been pushed in, the throttle is available for use by twisting. If the button is not pressed (is sticking out a bit further than when the throttle is on), the throttle cannot be activated with the twist mechanism. The throttle power switch is a latching type switch, so once pressed, you do not need to hold it down.

Pedal assist (PAS) can be engaged for a more traditional bike riding feel, as pedaling will call up assistance from motor based on the level of assistance you've selected.

You can select the desired level of pedal assistance between level 0 through 5 using the up and down arrows on the LCD display remote located on the left side of the handlebar. Level 1 corresponds to the lowest level of pedal assistance, and level 5 corresponds to the highest level of pedal assistance. Level 0 indicates pedal assistance is inactive. Start in PAS level 0 or 1 and adjust from there. For more information, check out the Pedal Assist Features and Operation article.

 Users must become accustomed to the bike’s power control system before operating. The throttle mechanism allows full power to be activated from a stop and inexperienced users should take extra care when first applying the throttle. The pedal assistance feature is also a powerful option and users should fully research and understand how to operate it before first use. Not taking care to familiarize yourself and practice the operation of the power system on your bike from Rad Power Bikes can lead to damage, serious injury, and/or death.
