To provide a bicycle trainer with which a wheel is less likely to come off even during low-speed running. A bicycle trainer 100 includes a pair of front wheel rollers 10 and 12 to support a front wheel of a bicycle, a pair of rear wheel rollers 20 and 22 to support a rear wheel of the bicycle, and a belt 66 to transmit a rotation of the rear wheel roller 20 to the front wheel rollers 10 and 12. The front wheel rollers 10 and 12 support the front wheel of the bicycle such that a trail when the front wheel of the bicycle is put on the front wheel rollers 10 and 12 becomes equivalent to a trail when the bicycle actually runs on a road surface. The bicycle trainer 100 further includes front wheel roller adjusters 14 and 16 and rear wheel roller adjusters 24 and 26. The front wheel roller adjusters 14 and 16 adjust postures of the front wheel rollers 10 and 12 such that contact positions where the front wheel of the bicycle contacts the front wheel rollers 10 and 12 become constant. The rear wheel roller adjusters 24 and 26 adjust positions of the rear wheel rollers 20 and 22 according to a driving power or a fictitious force of the bicycle.
