Some pictures of the drive unit for one of the wheels. The large belt pulley has the bearings fitted into it so the
stub axle will be fixed (just a bolt though it will be 12mm diameter so I don't expect it to bend!) also the wheel
retaining bolts will screw straight into it, so there is no need for a separate wheel hub thus saving weight.
the drive unit is the faithful Bosch 35w motor. this will be run at the standard 12v, the reduction ratio is
a little over 5:1
I am hoping it will prove a little more reliable than the expensive things that only lasted one fight!
