I have been reading about some pretty cool electric scooters lately.
This one is pretty inexpensive:
It is only $1999. But it has a 40MPH top speed and only 45 mile range. It uses Lead Acid batteries.

The previous model was no longer there. It is now replaced by the R30 at EVT America that costs $2890 and has a 45 MPH top speed and a 30 mile range.
This one is better, but a lot more expensive:
$11,000 but Max speed 62MPH and 68 Mile range. It uses NiMH batteries and a brushless motor.
