Road bicycles are just that, bikes made for efficiently riding on roads. You’ll know a road bike when you see one. It’s characterized by its sleek look, with dropped, curving handlebars, narrow wheels and “skinny” tires, a small seat and lots of cogs, or gears, on the back wheel. Typically, road bikes are lightweight, and oftentimes they look “fast.” That’s why they’re sometimes referred to as racing bikes.
