Bicycle trainer stand and trainer device

Abstract

A bicycle trainer stand comprises supporting means for supporting to a base, a lower support connected to the supporting means, and an upper support ( 14 ) connected to the lower support and comprising fastening means for connecting to a bicycle. The upper support is tiltable around an imaginary rotation axis with respect to the lower support. The trainer stand further comprises first spring elements for subjecting the upper support to a force opposing the tilting. In the invention, the lower support is movable with respect to the supporting means in a direction perpendicular to said rotation axis. A bicycle trainer device comprises a first trainer stand for fastening to the front fork of a bicycle, and a second trainer stand for fastening to the rear fork of a bicycle.
