What factors effect battery range?

Three of the factors that affect battery range are: riding style, riding conditions and load.

Riding Style:

  • Riding style’s impact on range depends on how much effort you want to provide versus how much assistance you ask of the drive system. Simply put, using higher power assist levels will decrease battery range greater than lower power assist levels. Speed will also affect battery range. Lower riding speeds require less energy from the battery than higher speeds.

Riding Conditions:

  • Riding conditions such as climbing, wind and temperatures all impact battery range. It’s no secret that riding up hills requires more energy from the drive system than riding on level ground. Head winds also require more energy to overcome and have an impact on battery range. Cold weather is another culprit in reducing range since battery packs perform best when warm. During cold weather, you can increase range by storing the battery indoors (between 59F and 77F) before use.


  • The weight of the bike, the rider and all cargo carried contribute to the affect battery range. And don’t forget about rolling resistance. Properly inflated tires will go a long way in maximizing the battery’s range.

How long does it take to charge the battery?

Our 500Wh battery pack can be charged on or off the bicycle and will take approximately 4 hours to go from 0% to 100% charge. However, the battery will reach 75% charge in approximately 2 hours. The last 25% of the charge is completed on a slower cycle that is best for battery life longevity. In addition, it is always recommended to perform battery charging between the optimal temperature range of 59 and 77 degrees Fahrenheit.
