Range indications

The table is a good indication of the range to be expected, under comparable conditions:

  • 360/470/570Wh full battery
  • Outside temperature between 12 and 30 degrees Celsius
  • Flat road
  • Total weight betqween 95 and 105 kg (weight of rider between 70 and 80 kg)
  • Light wind.



The range is an estimation because it is dependent from:

  • the level of support
  • the technical state of the bike (well oiled chain, optimal tyre pressure etc.)
  • the total weight of the system (bike, biker, and luggage)
  • the road (flat or hilly)
  • the weather (temperature, tail or headwind).
