Modular Drive Units. With these modules you can easily construct a mobile platform that is exactly the length and width you need.

The tube houses a two stage chain & sprocket speed reducer and a 4" wheel. It bolts right up to our E–150 motor or either of our S28 magmotors or you can use it with your own motor.

This unit is even easier to use than a motor with a built–in gear head because our modular drive unit includes a wheel.

Just bolt it in place, plug it in, and go
