"The ENV bike looks like a muscular motorcycle but runs more like a moped. Weighing in at 200 lbs., the aluminum bike travels at speeds of up to 50 m.p.h. on its Hydrogen-powered fuel-cell engine.
The ENV runs silently on a 5-oz. canister of hydrogen that costs about $4 and can power the bike for 100 miles. The drawback? California is the only state with hydrogen fueling stations."
"Project director Andy Eggleston says that proprietary technology allows the fuel cell to produce more energy than is typical. The ENV runs silently on a 5-oz. canister of hydrogen that costs about $4 and can power the bike for 100 miles. The drawback? California is the only state with hydrogen fueling stations, so filling up outside the Golden State could be tough."
