28 mph is the maximum assisted speed the bike will provide. 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. 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 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 proper use of your shifter will help you to balance effort and assist.
- Check your load. The more the load carried by the bike (cargo, wind resistance, etc.), the more power your bike will require to achieve the desired speed. The system on the bike is setup 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.
