Motorbike towing cradle using a car with existing towbar
Step 1: It was a dark and stormy night, I was all alone, and then it went quiet, very quiet...
well not exactly, but that's usually the way a good story starts.
Actually I got a call from my son in the day, "my bike just died and it won't start again", yes lad it's called "seized" and it does go kinda quiet, it's what happens when the Yamaha autolube feature packs up, and so was born the need for the "one man bike towing cradle".
Step 2: The story continues..
My first attempt involved bolting L brackets onto my existing towbar which had holes to take the bike's axle. It worked but wasn't an ideal solution, no restraining straps and no ramp meant a lot more effort involved, and I had to take off the bike wheel every time.
So after some chitchat with young Karl (a colleague) who described the contraption he used, I came up with the following
Step 3: Requirements
1. An existing towbar
2. a welder
3. angle grinder or cutoff saw,
4. 9 Metres of 1cm thick dropper bar (used in the building trade)
3m for the ramp
6m for the cradle
5. 1 Metre of steel tube, I used a 900mm rectangular 25mm X 40mm cos I had it.
Step 4: Making the ramp
First the ramp, which hooks onto the cradle, so it's easily taken off, yet remains stable when on. I used 2m of bar to make the ramp, sides of 500mm long and ten sections of 100 mm as the cross pieces to join the sides, alas the ramp angle was too steep so I had to lengthen it to 800mm, (2.6m needed for the longer ramp), a 1m ramp was too long and interfered with the bikes back wheel.
