In the mid-20th century three-wheelers in Britain could be driven with a motorcycle licence and a number of makers got in on the act.
Here are five that made a mark. They're all still rubbish, however.
British? Well they did build examples of this German-Italian bubble car in the UK. Some had two wheels in the rear, while others were genuine three- wheelers. Well preserved examples from the mid-50s are in demand.
Another car made with one or two rear wheels, the Berkeley used motorcycle- derived two and four stroke engines from 322cc to 692cc and front-wheel- drive, with the Royal Enfield twin- cylinder models proving quite quick.
The Bond was advertised with plainly exaggerated illustrations to make it look like it could take the whole family. It couldn't, and a tiny engine meant it could barely get out of its own way. Come the Mini in 1959, it died. Deservedly.
BOND BUG 700ES
Using a Reliant engine, the Bug was Bond's 1970 attempt to make three- wheelers sexy. The two-seater wedge was product-placed everywhere, but only 2200 were sold in four years. Now in demand as a motor-show curiosity.
RELIANT REGAL SUPERVAN
For reasons unknown, many think that Del-boy and Rodney drove a Reliant Robin, but they actually used the even uglier Regal Supervan, which was far more practical for traders and importers of the Trotters' stature.
