Bertin Pacer

Bertin's new 30 h.p. single-cylinder pacing machine on which he will endeavour to pace a racing cyclist 100 kilometres (62.1 miles) in the hour.

Jean Bertin was a French cyclist who later built pacers which he piloted at many events in France and elsewhere.

Some of his machines were tandems, with a pilot in the front seat steering the machine while Bertin maintained control of the engine.
