Dubbed the Hy-Cycle, the bike converts hydrogen to electricity using a fuel cell to power an electric motor. Built by a team from the UNSW School of Chemical Engineering, the bike can travel up to 125 km - easing range problems typical of battery powered electric transport.
Like most electric bikes, the Hy-Cycle is a pedal assist model - you still do a portion of the work, but the electric motor kicks in to make it easier, especially going up hills. The hydrogen used is stored in a 2.5 KG cannister, before being converted to electricity via a fuel cell. This keeps a smaller Lithium-ion battery topped up, which then powers the electric motor itself.
The technology also allows the hydrogen cannister to be swapped out for a full one, making "refueling" instant. The bike has a maximum range of 125 km at 20 km/h, but can reach 35 km/h. Check out more info over at the UNSW newsroom.
