Fitness and leisure bikes. As the name suggests, fitness bikes are designed for an active and sporty lifestyle. Fitness bicycles typically have large 28-29 inch wheels with relatively low tread and rolling resistance suitable for riding on hard smooth surfaces (city streets and parks), some models may also have shock absorbers and disc brakes to allow you to comfortably and safely negotiate even small obstacles, as well as short journeys on gravel roads.
A modern fitness bike is versatile and can be equipped with mudguards and racks and various accessories and will also be suitable for everyday use, holiday/touring trips with family or friends.
