There are several factors that affect the range. Terrain, rider’s weight, riding habits, weather and battery conditions are few main reasons. A flatter or a downhill surface will lead to a higher range than the opposite. If the bike is maintained and cleaned regularly, it could result in a smoother ride, and a longer range. Temperature below -4 C can reduce the battery performance by 70%. The battery health also affects the range of a bike. If a bike is drove at a higher power assist level, the range will be compromised.
