Basically, these power-assisted bicycles happen to work alongside a charging system that incorporates the “automatic storage battery charging system” that was developed by Kawasaki Trading. Conventional power-assisted bicycle sharing systems will see riders remove detachable storage batteries and place them on the chargers, but the non-contact-type charging systems used here will be able to juice up whatever storage batteries used without having to remove them from bicycles in the first place – which is an added level of convenience. I suppose the next level of evolution for such a system would be to consider a non-contact system when it comes to charging, but it would most probably cost a fair bit – hopefully in due time, the total cost will drop. A fully charged battery on one of these bicycles ought to be able to bring you around on a 30km journey before running out of juice.
