Since electric bikes were marketed, more and more of us are using this means of transport to go to work but also for leisure at all ages! Autonomy is probably the most important thing for an electric bike, which depends on the capacity of the battery: the greater the capacity: the greater the range. Beware, however: autonomy depends heavily on temperatures, the weight of the cyclist or even the gradient. Evolution Batteries offers you on request to communicate availability and pricing for your battery of origin or equivalent quality, but also to give a second life to your batteries. We are in a house to revise the batteries of all brands: BOSCH, NORTA, BATAVUS, GAZELLE etc… While keeping the case waterproof, we replace cells and thermal sensor. YOUR BATTERIES WILL WORK LIKE THEY STARTED!
