Estimated Range

Range varies significantly depending of motor power and battery capacity, and of course, depending on the selected power assist level. Other factors influencing range are nature of terrain, wind speed, gradient, riding style, total rider and cargo weight, tire pressure and temperature.

AIMA’s software provides the following estimated range figures based on a fully charged, brand new battery:

  • Assist Level 1: 80 km
  • Assist Level 2: 70 km
  • Assist Level 3: 60 km
  • Assist Level 4: 50 km
  • Assist Level 5: 45 km

For optimal battery health, avoid fully draining the battery. Instead, aim to recharge when the remaining capacity drops to around 10% to help preserve long-term performance and lifespan.
