The bare rack
With the MR Swift Trike
My wifes MTB added
The rack is welded from right angle steel approx 2 inch
wide on each flange. It's basically a cross, welded on its balance point
to a square tube that plugs into the car towbar (hitch.)
To make positions for the wheels, I cut short lengths of angle and welded them to form a trough; then welded a loop of 1/4 inch rod (13mm) to attach straps.
The main support is 3 inch square gal steel verandah post (I happened to have a spare bit...(as one does...)) I got the local exhaust shop to weld a standard Hayman Reese tongue into the end.
The MTB sits inside one trike wheel, straddling the trike cross member. The position was determined by making the trike cross first, then placing the MTB in position and marking the ground underneath. I measured and welded the MTB support. It's probably fortuitious that the MTB doesn't touch the trike metal to metal. I've padded the trike frame where the MTB frame is likely to chafe it.
Regulations in Australia require a 'number plate' with lights if the cars lights are obscured. These lights are wired to match the trailer plug on the car.
We own an RV (17 foot caravan). I have fitted a Hayman Reese socket to its rear so that we can take the bikes with the 'van. Park the van, then change the bikes to the car and roam farther afield.
Fuel consumption is increased by approximately 2 litres per hundred kilometres with the bikes on the rack. There is a lot of pressure generated on the trike and MTB pannier bags, so it's best to remove them. We roll up any safety flags and tape them during travel.

This is my DIY welded angle rack designed to plug into the Hayman Reese hitch (towbar)
