As a former bike racer myself, I'd say it would be a real workout, the
only problem with this pedal power recharging system, is the borebom,
exersice bikes have always been a least favourite amongst cyclist. Look
at 200w for an average fit person, then you have only 35% effiency of
the alternator, 70W gives about 5 amps. At least it solves the problem
of lack of aerobic exersice on a passage.

You can get closer to 70% efficiency if you go to a permanent magnet
alternator rather than an automotive style.

But the rest of your numbers are right on.
