Floor pumps, for road and mountain bikes, are the largest style of bike pumps and the easiest method to manually pump your tyres to the correct pressures. These are available from 99 Bikes in store and online. Floor bike pumps allow the user to exert a large amount of pressure down the chamber, through their large bases anchored by the user's feet, making it easier to push air into your tubes quickly and efficiently. Given their size, bike floor pumps aren’t suitable for taking along on rides, which is where a hand pump comes in handy.
