Maybe it would be more comfortable to ride if it had wheels instead of legs. And then it could be propelled by a single electric motor. And perhaps it could also be propelled by manual effort, maybe some sort of rotary contraption you could manipulate with you legs. Leaving you hands free to steer. Steering would be easier if there was like a bar or something you could hold on to.
