Suzuki Crosscage - concept bikes

As part of Suzuki's development of environmentally-sustainable technology, the Crosscage represents a feasible alternative-fuel vehicle. Protected by the sturdy cross-shaped frame cage, a compact, air-cooled fuel cell powers the Crosscage, with a hydrogen tank sandwiched between a fuel cell and lithium-ion battery. Oxygen from the air reacts with hydrogen and is converted to electrical energy, creating an environmentally-friendly and stress-free motorcycle. 

Suzuki Crosscage specifications:
Overall length: 1,985 mm (78.1 in)
Overall width: 645 mm (25.4 in)
Overall height: 1,020 mm (40.2 in)
