Typically electric bike weight is around 7kgs more than a comparable traditional bicycle (roughly 20kgs).
The very lightest electric bikes are those with an internal (concealed) motor. Systems such as the Vivax Assist add just 1.8kg to the weight of a bicycle. However, they only provide low levels of powered assistance and small batteries mean that power may only be used sparingly.
More conventional electric bike conversion kits such as the Cytronex C1 weigh as little as 3.6kgs. However, at the lower end of the weight range, you can expect less powerful motors and smaller capacity batteries. This means less range and less assistance up hills.
An electric bike with a more typical range and power carries about 7kgs of battery and motor.
Bikes using large-capacity sealed lead acid batteries are the heaviest.
When choosing an electric bike or conversion kit remember that you may need to lift your bike onto a car rack or carry it upstairs.
Guidelines for lifting at work are that a man should not attempt to lift anything heavier than 25kg. A woman’s maximum limit is 16kg.
We advise against putting electric bikes on to roof mounted car rack. Maximum recommended weights for lifting above shoulder height are just 10kg for men and 7kg for women.
