Show NOVEL SPEED INDICATOR FOR STATIONABV IIACEHS. Exciting races, tho participants In which sit on stationary bicycles, aro hold In tho gymnasium ot tho Gran'l Rapids, Mich., Y. M. C. A., with tho aid of a novel speod Indicator. Two bicycles are each Installed on a sot of rollers which aro connected by moans of speedomoter devices with a miniature race track set In full view of the riders. Two toy bicycles with riders, aro mounted on this track and aro connocted with tho speedomoter attachments in such a way that tho largo bicycles drlvo thorn round the track. Ono trip of tho toys around tho courso represents half a mllo of blcyclo riding. Tho fact that tho speed of each tiny blcyclo blcy-clo Is governed by tho rate at which tho corresponding largo blcyclo is driven gives nil tho zest of an outdoor out-door race to tho contest.
