“At the other end of the power line used to recharge electric vehicles is a motor of some type. Hydro, nuclear, etc. turning turbines.”

I did not say at first that a motor drives the turbines. You have water falling a certain distance, head, that moves a turbine.

Or you have nuclear rods heating water that then drives turbines, exiting to a lower temperature.

Hydro and nuclear refer to the source of energy. The water in either case is not the engine itself.

If you misunderstood what I was saying sorry. Maybe it was the interchangeable use of the word motor versus engine which technically is not correct.

The point of the post was that the electricity for an electric motorcycle must be generated by a generator of some sort, whether its energy comes from on-board gasoline or hydro, nuclear, coal, etc.

For right now it is easiest to have the motor on-board, that is, a hybrid vehicle.

Even if you have a low center of gravity for a motorcycle weight makes an enormous difference.

That’s why top-of-the line Ducati’s have carbon fiber. Ideally you want the dry weight to be less than 400 pounds. Having been on a number of bikes I can tell you weight makes a huge difference.

Steam, not water.

or on-board fuel cell.

“For right now it is easiest to have the motor on-board, that is, a hybrid vehicle.”

The hybrid has both a motor and an engine making it more complex. Also, using grid power, the EV can use many types of power sources reducing oil demand and prices.

Some systems such as the combined cycle NG turbine units run at 60% efficiency giving the EV at least a 2:1 efficiency advantage over gas cars.

Have you ever been on an electric?

There is no ideal weight.

The world’s best Superbike is over 400#.
