Yes, I think it is a Free Spirit - I can't check right now but that sounds familiar.

It's a 10 speed and the gears are changed by using 2 levers that are in the centre of the handlebars (I've not seen that kind before but I'm from the UK and I'd never heard of coaster brakes before either - although this bike has regular hand brakes).

I just asked a friend about it and he agreed that I shouldn't go off high curbs or similar with that kind of bike.
