The prototype bipi

Today I was dubbed insane by a guest who came round for lunch. A 40kg weight for a bike trailer will, apparently, make this mission impossible. Rubbish. Good name for a film though. So I went out into the yard and got a feel for what I was up against.

This time when I went outside I was in Wales with all the hardware and tools I could dream of. I sawed off a fence post for the crossbar, found some rails to simulate the poles and tied them to a sacktruck at the back.





I'm notoriously crap with knots, but here's how I managed to string the crossbar and poles together. Also, two ties run from the ends of the cross bar to the bike frame to keep the crossbar horizontal:



And it worked!!! Hahaha! Tim, if you're reading, I'll have the 'norick tc-2' with the 'spectra blue' visor please:



AND THEN, I put not one, but TWO feeds sack on the back of the poles. That 50kgs motherfu****! And it went - and slightly up hill too! So all the doubters can kiss the fattest part of my ass.

That said, there's a few things which need some work:

- We need some hard core luggage straps to tie these poles onto. Nylon won't cut it.
- Gonna have to make that carriage out of something suitable for the road. The sack truck wheels were far too small. Bike wheels would be perfect - gonna have to get welding.
- The poles got in the way of steering a bit, so we need to play with the geometry of the carriage and the crossbar...

Suggestions, ideas, sexual favours all completley welcome.

yes ed, YES. The video proof is in the pudding, nice one my friend. I suggest we convene over a pint so that I can hear more about it.
