The short answer to this question is far enough!

Users are concerned that they run out of battery power and then will have to use human power. In 99% of cases this will not happen. Research indicates that e-bike users do on average, less than 45km at a time. It is only if you push the boundaries that you will run out of power. Such as, using the throttle extensively, no pedalling, going up steep hills and over play the time in the saddle. Under normal circumstances a 10 Ah is sufficient for the average user of an e-bike.  The LCD display also indicates how much power is still available.

Predicting range depends on a number of factors:  for instance, if someone weighs about 70kg, riding across varied terrain with moderate undulation and a steady cadence of 70-80 rpm with a moderate PAS setting and occasionally using the throttle you can expect to get anything between 60-85 km  (even 95 km) from a single battery charge.

The following influences the battery usage:

  • Your weight
  • The terrain (how hilly and also how steep those hills are)
  • How much and hard you pedal (very important)
  • How often and how much throttle you use
  • The PAS level you use

Logic dictates that if the above are all “negative” then the 60 or 70 km range becomes less.

All batteries have both a Voltage and Amp Hour rating. If you multiply the two together, you get Watt Hours. Watt Hours is an objective measurement of the actual amount of energy stored in a battery.
