Brompton’s Electric Bicycle
Brompton were promoting their new electric bicycle at Kings Cross.
It looks a neat front wheel drive, pedal-assisted design.
At nearly £3,000, it would only be a bike for a serious commuter. Although, I suspect many will buy one to potter around their local area.
What I found interesting was that the battery weighs three kilograms and has a capacity of 0.3 kWh.
This energy density is very much in line with the most efficient, large traction batteries in road vehicles, trains and trams.
Well I suppose it folds up, but with a large unsprung weight over the small front wheels it is going to be a rough ride on anything but the smoothest roads. Surprised it does not have hub gears at the back. Then there is the price – £3k is three to five times the price of alternatives from Raleigh and others.
