Is it practical to change the gearing of the motor? You'd lose some acceleration though...

Also, worry about whether the braking is up to it.
You could put a 2v lead acid battery in series with the existing one, must be same amp-hour rating, must modify charger to work with it. Whether the motor will last is iffy, but it might survive. 12v... no, no chance.

You may be embarking on something you didn't anticipate if you start tinkering.
Power goes up roughly as the squaee of the applied voltage, so doubling the volts will net you 4 times the power and proably let the magic smoke out of the motor :-)
If you REALLY want to have a go, use a starter motor and a 75A/h car battery :-)
Battery lasts about 5 minutes between charges, and the motor will be shot in an hour, but in between its - quite fun:) Those motors are a few hp :)
re-motoring is probably your best bet, or rewinding the one you have.
Something out of a cordless power tool might be a place to start.
With a conntional pushbike I have done a car battery + starter motor running on the outside of the back wheel. Switched by the solenoid switch from an old mini (with a manual push switch between the terminals) Very exciting, however a bit heavy to push up hill when the battery goes flat. Also a bit light on the front wheel - can do a literally electrifying wheelie!
What is the law on these electric scooters and quads that have kids riding them dangerously all over the place, on and off pavements? Some the children look too young to drive a motorised vehicle.
cars & quads ..?
a
and lawn mowers, and motor vehicles.
they must be motor vehicles then.
I think we have one here.
