BRAKE- AND CYCLING TESTS WITH DIFFERENT TYPES OF BICYCLE

BROMS- OCH MANOEVERPROV MED OLIKA CYKELTYPER

First the manoeuvre and balance performance of standard-, rodeo- and speedway bicycles are compared in tests. The performances have previously been shown to differ between rodeo- and standard bicycles. The purpose was to find out whether the saddle design affects the performance of the rodeo bicycle. The speedway bicycle was used as a control. The tests show that there is no reason to assume that the design of the saddle should be the cause of the bad performance of the rodeo bicycle. In a second experiment brake- and reaction distances, as well as the use of two different types of braking system, were compared. The foot brake alone was used and compared with the combination of both hand- and foot brakes. Preliminary tests were also made with a new type of control, a hand brake which works as a reversed throttle twist grip for mopeds; the idea being to utilize a natural motor defence reaction. The results show that even children obtain significantly shorter stopping distance if they use both hand- and foot brakes. With the new type of control the stopping distance is longer than with controls of traditional type. However, no significant difference was shown in the reaction distance, despite the fact that the cyclists were not used to the new type. /TRRL/
