We haven't seen many electric motorbikes yet, though ebikes (bicycles) are taking off. It'd be interesting to see how the two merge (fast/powerful ebike vs electric motorcycle).

To me the main concerns are:

- Commodity vs personal: taxis, trains and hire-bikes are convenient from a shared-ownership perspective, but inconvenient in that you can better customise the experience of having you own vehicle.

- luggage & shelter: a bike / motorbike limits how much luggage you can carry. Also, a car is a much nicer environment that motorcycle leathers in all-weather; It's also easier to get in/out of a car than it is to change clothes.

I wonder if some of this can be improved by mere infrastructure: better dedicated roads highways for certain types of vehicle, better (secure) parking, city storage facilities for commuters etc.
