That depends on the structural design. It is important that the suspension is isolated from influences from the driving forces. This is easier and more robust to achieve on a recumbent than on an upright bike, on which you pedal in the same direction as the suspension moves. It’s true: A good bicycle suspension doesn’t waste energy, you can even go faster. You can read more about this on our No Squat page. You can experience it very easily during your first test ride on a state-of-the-art recumbent bike or trike designed by HP Velotechnik.
