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.
i made one of these and had it knocking around my shed for ages. The one stormy dark cold wet night when i was on my own. the bike i was riding broke down. i phoned the wife told her where and what she needed. and was home and dry in less than an hour. just have to watch angles as mine scrapped on top of speed bumps. Thanks for a fantastic idea.

yes you defiantly want to undue the chain. with the engine not running the oil in the transition doesn't circulate

motorcyclewhat abouts the icy environment......i think this motorcycle should supported by something else

If you drive fast enough on an icy road to make the rear of the towed bike slide out, chances are good you've lost control of the car too. In which case the bike is going to be the least of your worries I felt this way was the easiest 1 man job to do, but feel free to improvise. P.S. I've never driven in an icy enviroment in Cape Town in the last 45yrs chances are good I wont see one either

I always wonder when I see one of these photos, if it's real, someone transporting a bike on top of a car, or just a gag. They just put it up there for a photo.
Nice one, though my mates 125 honda CG can be put in to the boot of the puegot 406... It's not easy though, this looks alot less effort, uncluding building... the bike shown is very similar though, is that a 50cc though...

This is an awsome design but the ramp looks like it might drag. but this is a nice design for a remake to fit a bike dolly to tow behind my truck.

Actually the ramp was designed to hook on and off, see pics in step 4, with little fingers at the top. I just toss it in the boot when done. The ramp is fine as is for a 50cc bike, +/- 80kg but will need to be beefed up for anything bigger...my 160kg odd 500cc Enfield flattened it, but the cradle's plenty strong.

Sorry I missed the part where the ramp detaches before. I think I may need to make an adjustment to you design to suit my needs but this is still a wonderfull design.

yup thats good to hear. Most of the time the engines dont become damaged. These bikes are nice for point a-b in town driving.

Nice. Stinks about the oil injection if thats whats wrong with it. My roomates Yamaha RD350 home made chopper had the system removed. The only draw back is having to pre mix gas but no worries about it stopping an sezing up.

Yep ... you hit the nail on the head, autolube blocked up and had a hot seize. no major repairs needed but it had to be towed some distance.
