It is but little harder to drive uphills than the ordinary, and a ten to twelve mile paceon a fair road is easily obtainable. Its steering action,foot motion, and position of rider are identical withthose of the ordinary machine, while one has the ad-vantage of being close to the , in a place ofcomparative safety. A large wheel, front driver and steerer, lever action. Springfield Roadster Bicycle. machine, of American make, was the SpringfieldRoadster bicycle. It was on the market for severalyears, and was much liked by those who fancy thattype of machine. The levers and clutch oscillate on a fixed axle,upon which the large gears rotate constantly after thepower has been applied, which transmits the motion to 176 WHEELS AND WHEELING, the large wheel from a fixed shaft. The clutch formsa f-inch roll-bearing for the gears. Thus, we avoidall strain and friction from the direct application ofpower to the main shaft or wheel as occurs in theordinary crank method, which method makes a sidestrain, and changes the friction upon the shaft orbearing case from side to side, as the rider alternatesthe application of power. To avoid all strain orfriction on the axle-bearing from joints, we havelapped the bearing case over the forks, making itrigid, with if-inch pa
