Since-single speed bikes lack gears, so the rider must exert more effort when pedaling uphill, making the rider stronger, which translates into better performance on any type of bicycle.
Bikes have gears so that a rider can maintain an even cadence (pedal speed) over a variety of terrain. Without gears, the rider needs to learn how to maintain difference cadences, thus increasing pedaling efficiency.
Fixed-gear bikes are a type of single-speed bike in which the rear cog is directly attached to the rear wheel, making the wheels spin anytime the bike is moving. This type of riding promotes a more effective pedaling style and increase flexibility.
Learning to ride a single-speed or fixed-gear bike takes time. Because a fixed-gear bike does not allow the rider to coast, it is best to learn this riding style in a safe environment.
Riding a single-speed bike is a fun way to change up your training program and help you avoid boredom by giving you a new set of challenges.
