Sun Fold Bike Concept

Fold-up bikes aren’t new, and they’re definitely convenient if you do plenty of commuting with a bike while hopping onto a train or bus in between, but the Sun Fold Bike takes things one step further by featuring a solar panel that enables you to ride around even at night – just don’t venture too far out then as you might run out of juice halfway, but then again, walking home ain’t such a bad idea after all since you’ll get to sweat it out.
