I intend on buying a friend of mine a transportation device. He really needs a way of getting round besides public transport but lacks both a way of getting his licence and the money needed to buy a car/motorbike.

I'm trying to figure out what would be the best option to take.
Both 2nd hand cars and motorbikes/scooters can be bought cheaply. In terms of petrol though bikes are much cheaper. On the other hand I think insurance is higher for bikes. But bikes are much less safe and require buying appropriate clothing which adds an extra cost.

The biggest advantage to a bike is that my friend can teach himself to use it as opposed to requiring another driver.

Anyway I don't know much about cars or bikes, besides what I mentioned, and would very much appreciate advice on which option to take and possibly how to go about getting one.

Thanks in advance,
Pensive
