The most important things about a racing bicycle are its light weight and the aerodynamic efficiency and ergonomics of the rider's position. To this effect racing bicycles may sacrifice comfort for speed. The drop handlebars are positioned lower than the saddle in order to put the rider in a more aerodynamic posture. The front and back wheels are close together so the bicycle has quick handling. The derailleur gear ratios are closely-spaced so that the rider can pedal at his or her optimum cadence.

A hybrid bicycle is a bicycle designed for general-purpose utility or commuter cycling on paved and unpaved roads, paths, and trails. Also known under such names as City bike, Cross bike, or Commuter^, the hybrid takes design features from both the road bike and mountain bike, with the goal of making a bike for general commuting and transportation. In general, hybrids use the mountain bike's triple crank, together with the latter's handlebars giving a more upright posture than road bicycles. They also usually use one of the kinds of brakes used on mountain bikes, namely linear pull, or disc. From the road bicycle they take the 700C (larger) wheel diameter for higher speeds, but use a wider rim and tire for increased strength.

A touring bicycle is a bicycle either specially designed for, or modified to handle bicycle touring. Unlike other bicycles, it is able to carry more luggage on racks mounted to the front and rear of the bicycle frame. Other typical features include a long wheelbase with sturdy wheels for carrying a heavy load, mudguard/fender mounting points and triple water bottle mounts.

Utility bikes usually feature an upright riding position. The handlebars are almost always curved back and positioned higher than the saddle so that the rider can operate controls without changing his or her riding posture. Some people add a child seat or a trailer. The utility bike's combination of parts, design, and features provide functionality and comfort at the expense of weight, an adequate compromise when used as originally intended (relatively flat terrain for short distances).

All-Mountain (AM) bikes bridge the gap between cross-country and freeride bikes, typically weighing between 30 and 35 pounds (14 to 16 kg). These bikes tend to feature greater suspension travel, frequently as much as 6 inches (150 mm) of front and rear travel, often adjustable on newer mid- and high-end bikes. They are designed to be able to ascend mild-to-moderate inclines and descend steep declines, though their relatively heavy overall weight limits their utility in all-day rides involving steep climbs.

Racing BMX Bicycles

Race bike frames can be made out of aluminium, or steel, usually 4130 chromoly. The front and rear axles are 3/8" thick. They almost always have v-brakes, thinner chains, more aggressive, low pressure dirt tires, sometimes less spokes, and still widely use larger gearing than all other forms of bmx bikes.

Dirt / Park BMX Bicycles

Park bikes are very similar to street bikes. However, some park riders prefer to use brakes (rear or both) for an increased variety of tricks and more control. Park bikes may differ from street bikes in the fact that they are not as reliant on heavy duty high-strength parts, as park riding is much less stressful on the bike. Dirt riders usually don't have pegs unless they want to do peg-specific non-grind tricks such as rocket airs, and they use knobby tires for better grip in the loose dirt. Dirt bikes also tend to run only a rear brake and have longer top tubes and wheelbases. Many riders use bigger bars for more control, although big bars have become a trend among kids and popular professional riders. Dirt bikes generally at least have chromoly top and down/seat tubes and forks to increase durability and prevent bending of parts (especially forks) when landing large jumps.
