How much energy does an electric bike use? For the same penny or two it costs to keep a 100-150 W bulb burning for an evening in our home we can charge an electric bike that may propel us over a substantial and hilly distance! Of course the actual numbers vary with the specific bike, rider, riding conditions, type of bulb, cost of power etc. In Seattle some riders find that they spend less than $1 per month charging their bike (with 94% of the utility power coming from renewable sources).
The electric bike may thus be a rough equivalent of a 1,000 mpg automobile. (Please don't call us. We don't know where you can buy such a car).

Our electric bikes come with a smart charger: It is small and light and plugs in between the 'energy set' (the battery in its case) and the wall outlet. The quick-release energy set is removed from the bike in seconds for charging, if necessary away from the bike itself. A Lithium battery may be opportunity charged regardless of level of charge, i.e. adding a full or partial charge at any time. Charging a close-to-drained 9-10 AH battery takes up to about 5 hours. If you want your Lithium battery to last long do avoid routinely completely draining it and avoid letting it sit drained, otherwise this new technology it is rather forgiving.
For charging instructions please see the specific brand page.
