I agree Doggers, ebikes are not as visible as the figures suggest they should be. The estimates are just that, and there's no doubt makers are keen to put a positive spin on sales because ebikes are their only growth area, and handily are also high ticket. Outside charging is a thought, although I'm not sure if it is needed. The lumpy down tube or carrier batteries you will have seen on ebikes give a range of roughly 40 to 50 miles - enough for the majority of users. Charging after every ride is not such a problem because, like push bike rides, the majority of journeys begin and end at home with an overnight gap in between.
