The firm’s Alpha bike runs for about 100 km (62 miles) on a two-litre tank of hydrogen, a range similar to an electric bike, but a refill takes only minutes while e-bikes take hours to charge. One kilo of hydrogen holds about 600 times more energy than a one-kilo lithium battery.

The bikes are really expensive, and the charging stations even more expensive, but they do plan to bring these to the consumer market in the coming years.
