World's first fuel-cell e-bike gets a big boost in range

Originally, the Alter Bike utilized a 200-bar (2,901-psi)-capacity gas cylinder, which reportedly delivered an electrically-assisted pedalling range of about 100 km (62 miles) per fill. Now, Pragma has swapped in a 300-bar (4,351-psi) carbon composite cylinder, increasing the range to a claimed 150 km (93 miles).
