Suitcase bike

NO RATINGS

This bike fits in a suitcase, under the seat of a small plane, or in the trunk of a car. Folded, it measures 36 x 21 x 12 inches. Weighing 18 lbs, the bike comes with a three- or seven- speed gearbox.

A chain connecting the front sprocket to a triangular gearbox powers a pair of small, tandem rear wheels. Tandem wheels provide a more comfortable ride than a single-wheel design. An air gap between the front tandem wheel and the road keep it from dragging during turns.

Adjusting the wheel's height lets the rider customize the ride for different terrains. The wheel makes contact intermittently to absorb road bumps. Although not in production, the cost is expected to be in the $800 to $1,200 range.
