How many levers dose a mountain bike have?

Thre are several ways to interpret that question. If you're asking about things that are actually called levers, then the answer is probably 4 - one pair of shift levers and one pair of brake levers. Unless it's a gripshift equipped bike, in which case it'll only be one pair of brake levers. Or maybe it's a single-speed, in which case it also only has brake levers. Or maybe it's a fixie, which don't use shifters or brakes. Or its using rear gears only, giving it 3 levers. One shifter, two brakes. Or it's a rear gear gripshift - two brake levers. Or maybe you're asking about the mechanical definition of levers, in which case there's be a lot more. The handlebar is a lever, each crank is a lever, the wheels may be seen as levers. If you've got quick-release wheels and seatpost, those are levers too.
