Mountain bikes or trail bikes have tires that have a lot of little bumps or tread to give traction on dirt or in mud. When you're riding on a paved path or road, you don't need all that tread, so you can use a smoother or "slicker" tire, so those tires are called slicks. The tread does slow you down a little bit when you're riding it on road. You can get hybrid type tires that are smooth in the middle and then have a little bit of tread on the side in case you need traction cornering or if you go off on a trail. Zen's bike has 26" tires, I think. Most road bikes have 700c tires.

But don't worry about all that stuff now, we can help you with that once you decide on a bike. Go test ride some.
