There are many factors that affect the total cost of charging an e-bike battery such as electricity price, battery size and battery age. However, you can use this guide to get a rough idea of what to expect. 

To calculate the cost take the battery capacity (Wh) of your e-bike and convert it into kWh. To do this simply divide by 1,000. Now multiply by the value you pay for electricity (in kWh) and that will give you the cost per charge. Assuming the battery is completely empty and you give it a full charge. 

How often an e-bike needs to be charged not only depends on how often you use it but also on how you use it. For instance, if you have an e-bike on its maximum level of assistance it will need charging more often than if you were to have the assistance turned down. 

Putting usage to one side, an e-bike with a larger capacity of 700 Wh can do up to 70km on a single charge. Where as a bike with a smaller capacity of around 300 Wh will do upwards of 30km. 

Again, this is something that varies massively by battery capacity, battery type and the type of charger being used. However, as a guide, you can expect a full charge to take 3-7 hours. 

Here are some example bikes offered on the DASH platform with varying battery capacities and how much it costs to charge them. We have used an electricity cost of 34 pence/kWh.
