pedal by wire
It's got "barstools" along both sides and the passengers/revelers are supposed to turn the pedals under their seats while the bartender/driver steers.
In reality, the pedaling charges the battery somewhat but the vast majority of the battery power comes from being plugged in at a charger before the ride. You can't actually rely on a bunch of drunk sods to keep it moving.
So, like, no nudging the right handlebar forward to turn right? Bummer!
That capability is much more important than the efficiency loss of the generator/motor powertrain.
Such capability is not necessary on a bicycle, where efficiency is extremely important.
