<p>The bicycle training machine consists of a rigid frame with short legs (10), and two lengthwise girders (11a, 11b). It is cross braced at the back by the axles of two rollers (14, 15) mounted freely and resting against the drive wheel of a bicycle. It is also cross braced by one roller (16) at the front. Rigidly fixed to the lengthwise girders at the front, on a level with the front cross-brace, are two uprights (18a, 18b) joined at the top by a cross-piece (19). This has two tabs (20a, 20b) on top to which are bolted the two ends of the bicycle fork, after the front wheel has been removed. The two uprights (18a, 18b) are telescopic and can be adjusted in height.</p> |
