Scott Cyc-Auto 98cc
28 DECEMBER 1950
Road Tests of New Autocycle
A 98 c.c Two-stroke Autocycle with Lively Performance, Good Manners and Efficient Silencing
The unusual layout of the Scott two-stroke engine with its worm primary drive makes the Cyc-Auto especially interesting among autocycles. . In line with the frame of the machine, the crankshaft, at its front end, drives the flywheel-type magneto; at the rear end there is a transmission brake and clutch coupled to the worm drive housed ‘in the special bottom bracket of the frame. Final drive is by chain in the orthodox manner.
Cutch and transmission brake are operated by a single lever on the left handlebar. As the lever is raised the clutch is disengaged, and further movement of the lever applies the brake, which proved to be an adequate means of stopping in normal traffic conditions. There are also front and rear wheel internal-expanding brakes operated· by handlebar levers. Both these brakes were outstandingly powerful and, used together, would bring the machine to rest in 27ft from 30 m.p.h. on a dry tar-macadam surface. Lever pressure required for a crash-stop of this nature was considerable, but the fact remains that, the Cyc-Auto is unusually well equipped for deceleration.
Handling, too, is commendably good. The power unit is placed low and “its weight is hardly perceptible. A consequence is that the handling is akin to that usual with a normal pedal-cycle. Steering is above reproach at all speeds and stability on the worst of wet road surfaces eminently good.
The link-type spring fork has a progressive action and is free from patter and rebound clash; on only one occasion was the fork noticed to bottom.
Position of the pedals in relation to the saddle and handlebar is approximately the same as with a standard cycle, and the pedal-gear ratio is average. As a result, when the engine is disengaged, the Cyc-Auto can be ridden as a cycle with far more ease than most autocycles; moreover, the peddle’s provide comfortable footrests when the machine is used under power.
