The MTB is the most common cycle sold in Karachi, and for good reason: thick tyres, multiple gears and a frame that survives potholes. Buyers looking for cheap mountain bikes usually go second hand, where a used MTB in working condition costs a fraction of a new one. Spin both wheels to check they run straight, and shift through every gear before agreeing on a price. Related options are listed under Hybrid Bikes and Road Bikes, or BMX Bikes for younger riders.
