Using the Sports Assist level, the bike will provide the programmed output and it will stop assisting if it reaches 28mph (As per- Class 3 bike regulation). Under certain conditions, the bike can go faster with pedaling, to add the additional power needed. Some conditions can result in slower assisted speeds as there is only so much power output available. For instance, climbing a steep hill likely cannot be done at 28 mph due to the power limit. The system will attempt to reach the desired speed but will consume more energy than tackling the hill at a slower, assisted pace.
Scramblers use a 20" fat tire which trades rolling speed for torque and maneuverability.
If you are on a flat road and are unable to reach an assisted speed above 20mph:
- Check to see if your bike is in Sports mode. This increases the cap limit from Class 2 to Class 3 and allows you to obtain more assisted power.
- Check the tire pressure. Your tire pressure should be around 10% less than the max pressure.
- Check your battery charge. Having a low battery will limit your bike's power.
- Use your shifter. As a pedal-assist bike, the system will use your pedaling to know how fast you want to go, and the proper use of your shifter will help you to balance effort and assist.
- Check your route. Conditions such as sand, hills, or bumpy roads will affect your maximum speed. Always use caution when riding in adverse conditions, as this will cause your bike to wear down prematurely.
