Battery Selection

Understanding “The Battery”

The performance of an electric bike is measured by its ability to climb hills and how far it will run on the flat at a constant speed. This depends on a light frame, low friction and a highly efficient electric motor but also on the energy stored in the battery, which is the fuel for the motor

Useful technical battery info…

In a battery of specified voltage (V), energy stored is measured in ampere hours (Ah). This measure indicates how many hours a battery can produce a fixed current – amps A.

The best electric bikes today use 36 V batteries rather than the 12 V familiar to us in car batteries. To produce the same power measured in watts, which is volts times amps (V x A) a higher voltage motor of the same power will need less current. A lower current allows the use of thinner lighter wires and a lighter motor to deliver the same power.

The FreeGo, LifeCycle and 3e electric bikes have been designed with 36 V batteries. These have a capacity of either 8Ah, 10 Ah for the lithium ion battery or 16 Ah for the lighter lithium polymer battery, which is often claimed to be 17.5 amps. So, in theory, they produce 288watts, 360watts and 576 watts respectively. The ranges of electric bikes we supply are fitted with 200watt or 250watt electric motors, which is the maximum permitted for road use in the UK. The combination of the high voltage 36 V X 16 (17.5) Ah battery gives our FreeGo Eagle and The LifeCycle Alpine Sport, Mountain Sport and City Sport the best range, best performance and hill climbing ability

The Batribike Breeze has a 36V X 8Ah battery and a 250watt motor

Nearly all our other bikes have 36V X 10Ah batteries and 250 watt motors

Axcess were the nearest specialist supplier of Ebikes, and there web page gave good descriptions. I visited their premises, tried out their folding models around the factory estate and on that basis chose a ELife folding bike as the one best suited to my needs. I have been pleased with the model I chose. - It is of robust construction with front fork suspension and it deals well with farm tracks and forest trails - it folds easily and fits in the back of the car - it shrinks distances compared with my old pedal bike - it has coped with all hills I have so far tried it on - I don't know what its range is (30 miles seems about right for gentle countryside). I had thought that battery capacity would be a limitation, but it is not. It is in fact saddle soreness.
I recently purchased the Axcess Electric Shetland folding bike which fits nicely In the back of my SUV without having to lower the rear seats. It’s an excellent bike and build .. easy to mount and dismount .. perfectly suitable for me as I am now in my mid fifties and appreciate a little assistance nowadays on longer journeys and Inclines , that said It’s a great bike for any adult whatever there age and as they say ... It has the power to get you there and back. I have previously owned two other electric cycles of another brand that were hard work to cycle when the power was off even on the flat. I’m pleased to say that this Is not an Issue with the Axcess Electric Bike that you can pedal with ease If and when the power Is not required ..
