Turbo Trainers from Tacx & Elite allow you to ride a bike indoors whilst it remains stationary. They are often used for exercise during winter months or by riders training or warming up for events. They have an advantage over a normal exercise bike by allowing the rider to use their own bike, and adjust the resistance to simulate going uphill or downhill for a more natural ride. The three kinds of Turbo Trainer are Rollers, Wheel-on and Direct Drive. They offer different benefits depending on your ability and experience. Direct Drive trainers are the most sophisticated and are compatible with computer programs to give a more realistic ride.
