The PHB is a hydrogen bicycle, power-assisted by an electric motor that gets its electricity from a fuel cell. It is manufactured by Pearl (SPHPST.Co), unveiled at the 9th China International Exhibition on Gas Technology, Equipment and Applications in 2007.
It can reach approximately 25 km/h and, on a full tank, may ride a distance of 60 to 100 kilometres. The motor is a brushless motor. The bike will sell (2007) for approximately US$2500, with further prices going down to $500.
As stated by the manufacturer, those who already have a bike don't need to change the original frame structure; the fuel cell can be directly integrated into the original bicycle.
