'Do it Yourself' 4WD

This is the descriptions of 3 different 4WD vehicles, which I made many years ago.

4WD vehicle no. 1 was built in 1977-79. It had full-time four wheel drive. There was no suspension except for the seat and the 4 psi only in the tires.

No safety belt yet (1977).

The motor was single cylinder, 2 stroke, air blower cooled. The rear wheel of the Vespa scooter motor was replaced with a sprocket and a chain from a moped.


The steering levers were connected to the brakes in both wheels at each side. The skid-steering demanded 'full throttle' to perform optimal. Safety belt was nessecary to avoid the driver to be thrown off while steering. The brake cylinders and the rear axle assemblies were from two Opel Kadett's.

The axles were welded together via rods to make a stiff frame. When the original weldings of the frame broke, I shortened the vehicle to minimum so I could transport it in my 1966 Ford Thames Freighter.

Having just 'turned' - changing gears (1979).

The gears were changed with a control lever. Accelerator and clutch pedals (like in a car).

4WD vehicle no. 2 was built in 1982. It had full-time four wheel drive and articulated frame steering. The two rear axle assemblies were connected by means of one single universal joint. The rear axle assemblies are unusual due to the long distance from differantial to drive shaft flange (Vauxhall parts).

Left front wheel is lifted 15 cm from ground (1982).

The motor was air blower cooled, single cylinder, 2 stroke with constant speed control. The crankshaft was fitted with a sprocket from a moped. The steering parts were from Volkswagen.

The very first ride (1982).

Later, a saddle and an 'ignition-off' switch were mounted. Neither accelerator, brakes, nor clutch was ever mounted on this vehicle.

4WD vehicle no. 3 was built professionally by me in 1990. It had full-time four wheel drive and skid-steering. Link to the description .
