What It Is: If it’s a bike built for fun—but not a road or mountain bike—it’s probably in this broad category that encompasses everything from flat-bar fitness bikes to beach cruisers. Some fitness bikes come in women’s versions with different touch points, and you’ll also find traditional diamond-frame and step-through versions in styles like hybrid, comfort, and cruiser. Sub-Types of Comfort/Fitness Bikes: Hybrid: Named because they share features of road and mountain bikes, these feature the upright rider position, broad-range gearing and flat handlebar of a mountain bike, with narrower, fast-rolling tires with light tread. Some have suspension forks as well. Fitness: These emphasize road bike-like efficiency without the aggressive position, with lightweight frames, performance parts, and narrow slick tires paired to flat handlebars for a more comfortable rider position. Comfort: These bikes are marked by wide, lightly-treaded tires, cushioned seats (and sometimes suspension) and a very upright rider position. Cruiser: The classic swoopy-framed beach cruiser with fat tires, one to seven gears and wide, chopper-style handlebars. What It’s For: As with urban, this category covers a broad range of use, and you’ll want to pick your style based on what you’ll do with it. Fitness bikes are made for working out; hybrids are great for rambles on paved or light dirt paths; comfort is perfect for a refreshing Saturday morning spin to the coffee shop.
