Fixie bikes derive their moniker from their fixed-wheel design. Riders must constantly pedal to keep the wheels moving — there’s no coasting with fixie bikes! Fixies are single-speed bikes with no gears, which makes them simple to operate and maintain. On the other hand, the no-gear design means that fixies are not the best choice for hilly landscapes, as the rider is unable to make the climb easier by shifting to a lower gear. Thus, fixie bikes are best suited for riders who prefer to stick to flat surfaces or do most of their cycling on bike tracks
