Portable Charger for EUC batteries with a Turbine or Pedal

Not to hijack the thread but slightly related.  I wonder if an old unicycle could be repurposed to be a turbine for a micro hydro installation

To generate electricity efficiently you want the magnets moving past the coils as fast as possible. The large diameter of an EUC motor ought to make it well suited to the task. However, you would really want just the motor, as a 3 phase generator and not the EUC’s electronics. I.e. you would be better off with electronics designed to work with a 3-phase generator.

At its simplest, you might get away with a waterwheel type set of paddles through a belt or chain drive to gear up the output to the motor. Thereby hangs the thought that an electric motor designed for the rear hub of an electric bike would be a better fit as you would have a suitable set of sprockets for a chain drive already fitted and even the ability to select different gear ratios with ease.

When we try to get more range from our euc first thought is swap battery but few models can do it. Instead of swapping we can connect a external one but the manufacturer again didn't think it and we cannot do it. Ok, connect the external battery to charge the euc, but the power lost is brutal and the time expend too much. Also is bad idea try to generate in place the energy for charge the battery. Most of solutions comes worse than walk carrying the euc. And that's the solution, but instead walk what we need is pedals to ride it like classic unicycle powered like a electric bike
