The bus takes a maximum of 20 people, and needs at least six to power the bus. One model had a row of seats at the back for pure passengers. The driver doesn't pedal, but steers and operates the brake. It can get up to about 25mph. (Here's another design, on YouTube.)I haven't seen one of those, but I have recently been in Berlin, where I saw a bicycle-powered two-carriage fake tram being pedalled through Mitte. I spoke with the two gents pedalling it, who told me that it was a consciousness-raising exercise to campaign for an extension of Berlin's tram network to the West (where it had been torn up in the 1960s, as not to get in the way of affluent capitalist Berliners' VWs and BMWs), and to help campaign for the Greens in the election.
