I saw an interesting machine in Nottingham city centre today, a rugged looking delivery bike with twin crossbars supporting an advertising board for "Pickwicks Sandwich Bar", outside of which it was parked with total immunity from the parking attendants. In the front wheel was a chunky looking hub motor, the power for which came from an aluminium box mounted on the twin crossbars, despite the fact that there are overhead wires for the trams I failed to spot a trolley pole so must assume there was a battery in the box. On the front of the bike was a large basket but attached to the rear was a huge trailer measuring at least 1.5m square and resembling a car transporter with two parallel tracks and a loading ramp which folded up to form a tailgate. I didn't see the bike in use but I'd guess that a loaded trolley is wheeled out from the shop and on to the trailer. Such a machine, which could probably carry as much as a small van must be immensely useful in an environment where anything with number plates that doesn't move gets an instant parking ticket. Sights like this are probably commonplace in central London but it is the first time I've seen an electric bike used as a delivery vehicle in the Midlands.
