Max Taillefer in "La vie merveilleuse de Georgia Knap" writes:
December 1901 Paris Salon
§ 6. - Ordinary motorcycles.
We can also use a Knap motor, 6 kg and a half, normally 2,400 revolutions per minute and directly driving, by a pinion and a gear wheel, the hub of the rear wheel, near which it is mounted vertically. A bag-tank is placed on the upper side of the frame. The bicycle, which weighs 14.8 kg with brake and freewheel, does not exceed, in running order, the weight of 28 kg. Five minutes is enough to remove the engine and its accessories.
§ 6. - Bicyclettes ordinaires à moteur.
On peut aussi employer un moteur Knap, de 6 kg et demi, faisant normalement 2.400 tours à la minute et attaquant directement, par un pignon et une roue dentés, le moyeu de la roue arrière, près duquel il est monté verticalement. Une sacoche-réservoir est placée sur le côté supérieur du cadre. La bicyclette, qui pèse 14,8 kg avec frein et roue libre, ne dépasse pas, en ordre de marche, le poids de 28 kg. Cinq minutes suffisent pour la débarrasser du moteur et de ses accessoires.
