Arch mentioned a need for a trailer today. I have been a bit lax and not made one for her yet. Anyway no sooner mentioned, on the way back from Aldi, then done as soon as we got home.
We had an old kiddie trailer and so that was stripped down to the basic flat frame. Then while Arch stripped the fabric for useful stuff I fitted a cargo net to the frame. It is held with a bit of cord so that it can be retensioned in the future. Arch will find a bit of correx for it as a floor when needed.
I also fitted a cycle computer too.
I had to make up an aluminium bracket that was shaped a but like a number '2' to hold the sensor and then make an 'L' shaped bracket to hold the magnet as there were no spokes to clamp it to.
The wiring for the sensor had to be extended with a bit of old speaker wire that happened to be exactly the same as the sensor wire and then the computer mount was screwed in place with a small wood screw.
I now know that at 7mph I am bouncing out of the seat on my electric tractor!
I wasn't quite at full throttle in top gear but close. On a flat smooth road I might get up to 10mph but not before I fit a bullet proof chain guard over the chain.
Here's a video of Arch test driving it.
