Peugeot Trekker (50cc) not starting?

Peugeot Trekker (50cc) not starting through the electric starter or the kick starter, stopped working last week. Just cut out in the middle of the road, granted it's old and was low on oil, but i filled it up, and nothing :(.. i don't know much about peds or any vehicles in general, i'll do my best to understand, but try and keep it simple if you can!
