I reckon that it was built for a laugh... coupling the electric motor in the 'robot' directly to the rear wheel would have been far more efficient - but far less fun!

A bit pointless I think. I don't reckon that it generates enough torque to contribute anything significantly and just serves as a weight on the bike. He should just take the motor out and leave the thing to turn under his own steam.
Does there have to be a point to everything?
