On hilly terrain, it is recommended that users always pedal to assist the bike in climbing up hills.
On steep hills, you should never exceed 500 watts of power. This can be accomplished by setting the pedal assist level to “Level 1” or "Level 2" or by riding with the twist throttle only partially applied. While regulating the throttle, watch the watt meter on the display and ensure that you regulate the power output of the motor so that it stays below 500 watts on steep hills.
Never ride up hills which exceed a 15 percent (%) slope with the motor fully engaged. If you need to ride up hills steeper than 15% grade, first set the pedal assist level to “Level 0, Level 1, or Level 2” to avoid exceeding 500 watts of power to the motor.
For hills that exceed your ability as a cyclist, a rider can always dismount the bike and walk, while pushing the bike or engaging "walk mode." Walk mode is a feature that allows the motor to move the bike at a relatively slow, constant speed so that a person can walk next to the bike with their hands on the handlebars, without having to push the full weight of the bike. For more information on engaging walk mode, please see the LCD Display Features and Operations article in the Help Center.
