What size of electric motor can carry someone?

Whats the smallest motor that can probably move someone, for instance 49cc gas motor can move the bike and a person on it.

Can 1hp or 3 hp electric engine have enough power to move someone? Not on a bike necessarily

Answer
500 watts = 1/2 horsepower.

Electric mobility scooters and wheelchairs have about 1/2 horsepower motors.
Many recreational and commuter scooters also have 1/2 horsepower motors.

It's about gearing. You could easily use a 1/10 horsepower motor if you geared it to run a couple of miles per hour.

Electric Scooter or a Mountain Bike?

I'm a soon-to-be community college attendee, and I can't decide whether to get a bike or electric scooter for basic transit in the hillish areas of Reno. I loved my bike back home, but it was pretty much destroyed by a reckless friend of mine after I let him borrow it (he's making a speedy recovery). I don't have near enough for a car yet, and my license is invalid since I just moved. I just need something reliable and good for short-medium range transit around town.

Answer
Why is your driver's license invalid? Anyway, you need a driver's license for a motor scooter. And anyway, a mountain bike isn't the best commuter bike, a road bike is. If you're going to be riding gravel trails as well consider a cyclocross bike. If you primarily mountain bike on rocky singletrack a mountain bike can still be a commuter but you'll never be as efficient on roads as you would on a road bike. Of course the bicycle, whichever kind you decide you need, is the most efficient and cheapest form of transportation.
