Those tires on either of the the two bikes above. The commuter is heavier but has 48-12 as the largest ratio making a little faster at lower cadences. Its also much more useful for carrying kids and cargo. The other is much lighter but has 44-12 and its a little slower on top speed but much more nimble and an all round better bike for going anywhere. I ride either depending on where I'm going and what I need to do.
