An electric bike by Smart, the Mercedes-owned purveyor of little cars, has gone on sale this weekend. It’s got a 62-mile electric range and costs roughly the same as an 03 plate Smart ForTwo: £2,500. (Please, no complaints – we said “roughly”.)The pedelec (pedal electric cycle) can be ordered now for late May deliveries, though we don’t expect demand to outstrip supply for what is, basically, a mode of transport that retains all that’s harrowing about a bicycle but removes the major benefit – improved cardiovascular fitness.Still, it’s a stylish looking bike, and will make going up hills a doddle.
