This Carrera Transit Folding Bike sits just south of the £300 mark, and for that you get a rarity among cheap folding bikes: hub gears.

If you’re looking for minimal maintenance you should be looking at a single speed bicycle, or one with hub gearing like this. It means everything is tucked away from the elements and you’ll be riding for a longer period before having to go to the bike shop. Perfect for the busy commuter.
