Bicycle Rollers | Wikipedia

A flexible roller system allowing longitudinal movement

Balancing the bicycle without riding off the rollers is an extra challenge for the rider and requires much more balance and attention than bicycle trainers. Some cyclists find that this increased attention to balance enhances their workout, while other cyclists simply prefer the more stable trainers. Rollers are also used by bicycle racers to finely tune their balance, a skill needed for drafting and the close quarters of a peloton during races.

Novice cyclists often start by placing the bicycle rollers in a hallway or door frame where there is a nearby wall for support in the case of a fall. Removing any sharp and dangerous objects from the area is a must and a helmet is often worn, even though the user might be indoors. Beginners quickly discover that it is easier to maintain one's balance by focusing on a point a few yards ahead rather than looking directly down at the front wheel. In addition, it is easier to stay on the rollers in a higher gear when the wheels are spinning faster. Also, the user has no forward momentum while on bicycle rollers, which drastically reduces the possibility of injury in the event of a loss of balance or a fall.
