Range of an electric bike
What do I look for?
Indeed, if you think about it, the variety of electric bikes claims to be completely precise is impossible. Too many variables distinguish it from individual to individual.
- how much the rider weighs
- what level of peddle assistance the rider needs
- the landscape they’re cycling over
- the amount of cargo they’re hauling
- how fast they are going (1/3 faster = 1/2 the range)
- how hard pedal
- how many times they stop and start (hill starts in particular will drain power)
- wind conditions
- temperature (they will get about 15% more range from a battery on a warm sunny day than they would in winter)
- tire pressure (as with regular bikes, soft tires = less efficiency = less distance for power expended)
- what kind of battery they’re using
- how old their battery is (batteries lose power over time)
- Bike engine size (large engines are enjoyable, but obviously more battery energy is drained)
- how fast they’re going.
And if you have a lithium battery, for instance, you will continue to go much longer than if you have a nickel cadmium battery, because lithium batteries have a greater energy density.
Keep in mind that you need to match your battery size and your electric motor to get the optimum variety. Look for a setup where the battery capacity in watt hrs is equal to the motor capacity in watts as a general rule of thumb. This kind of setup will have the best bikes because the engine will not over-tax the battery. You should be able to get maximum assistance with this kind of setup for at least one hour.
For example, the Lanke Leisi C-750 Plus has a top-of – the-range has a 355 Wh (36 V/9.6ah) with the 500 watt battery. Thus the motor capacity and battery capacity are almost identical in watt hours, and the battery is advertised as having an impressive range of 60 miles! When we tested the LankeLeisi C-750 Plus 1000 Watt 48v electric bike we were able to go 16 miles up and down big hills without peddling. With peddling we could go 50 + depending on how much peddling we wanted to do. Our happy electric bike tester was 230 lbs and 5 foot 11 and loved every second of our tests…
