The single most common question about EBikes is, how far can I go? 

 Somewhere between 36 and 73 kilometres on flat ground. Many factors may even move this number lower or higher.

The formula to calculate battery power is as follows. Multiply the Voltage by the Amp Hours and divide buy the Wattage of hub and you get the time it will last if running full throttle.

Therefore, a 36v500w hub with a 36v16ah battery would be. 

36v x 16ah / 500w = 1.152 hours of full throttle operation.

32kph times 1.152 = 36.684k 

So at full throttle you would go over 36 kilometres if your maximum speed is 32 kilometres an hour (the legal ebike limit in Canada) you would go over 36 kilometres in distance.  However if you are on flat ground it only takes about 250 watts (about half throttle) of power to maintain a speed of 32 kilometres 36 x 16 / 250 = 2.304 hours of half throttle operation. 2.304 hours at 32 kilometres per hour is 73.728 

 

 

 

So on perfectly flat ground with a light rider and bike and no wind or stopping and starting you go over 73 kilometres and if you pedal go even further. Now this number also has many overriding factors.  Negative impacts on this number are the Weight of bike and rider, opposing wind and uphill climbs. These things take from the overall distance you can travel. Positive impacts on this number are favourable winds at your back and regenerative breaking that charges the battery when you apply the brakes to slow down or to stop Another positive impact on distance is very few people actually travel at maximum speed. I know I rarely do as I find the roads and pathways a little rough. I generally travel at about 26k, which increases my distance. Also quite often, I pedal to assist the motor and this increases the distance I can travel dramatically.
