1900 – Perks Birch, Motorwheel, UK, 222cc, single-cylinder,
top speed 22 mph.
The brilliant design by Edwin Perks
and Frank Birch incorporated an engine, fuel tank, carburetor, and magneto
within a two-sided cast alloy wheel.
1901 – Cyklon, Germany, 300cc, single-cylinder, top speed
22mph.
Cyklon used the French Werner
engine, mounted on the front forks and driving the front wheel by a belt,
placing the rider rather close to noise and fumes.
