Note: It is not recommended to overload the motor while going up a steep hill. This will wear down your controller and could damage it.
28 mph is the maximum assisted speed any of our bikes will achieve using the Sports Assist level. In ideal conditions, when pedaling or traveling downhill, it is possible to exceed this limit. Similarly, some conditions can result in slower max speeds. For instance, climbing a steep hill likely cannot be done at 28 mph due to the bicycle's innate power limitations. The system will attempt to reach the desired speed but will consume more energy than tackling the hill at a slower, assisted pace. If on a flat road you are unable to reach an unassisted speed of about 28 mph, follow these tips:
- Check to see if your bike is in Sport (or Race) mode. This increases the cap limit from Class 2 to Class 3 and allows you to obtain more assisted power.
- Check your tire pressure. The assist can cause us to forget about tire pressure as it compensates for the drag. Your tire pressure should be around 30% less than the max pressure.
- Check your battery charge. While in high demand, the battery will provide enough power to move, but the power will be limited if the charge is low.
- Use your shifter properly. 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 load. The more the load carried by bike (cargo, wind resistance, etc.), the more power your bike will require to achieve the desired speed. The system on the bike is set up to a have a certain point where it will max out.
- 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.
