On a regular rear wheel, there are cogs on just one side of the hub â the drive side. On a flip-flop rear wheel, there is a single cog on either side of the hub (although you only use one at any given time). One of is a fixed cog, and the other is a freewheel. The freewheel body means that the rear wheel can turn even when youâre not pedaling. In a word, it allows you to coast. A Flip-Flop Hub (such as the one on the Montague Boston) has a cog on either side â one that is fixed and the other that freewheels. On a fixed gear, you canât coast. If the bike is moving, your legs need to be moving.
