  • Hmmm, precision is probably not my forte. Just welding the headtube extension and bb boom joint might be easiest eh? Interested to see what you did at the bottom of the headtube extension, did you bother with a bottom headset cup?

  • Yep, welded the bottom headset cup into the bottom of the headtube extension. I cut a steerer out of an old knackered suspension fork then welded this onto a long piece of 1 1/8 pipe to make a mega steerer. This meant I could put the crown race on properly at the bottom.

    The first iteration snapped at the key join between headutbe and cargo base when carrying two small children across a park. No damage to the children, but I had to beef up this joint with the brace you can see in the box. Been good since.

    The front end is a kids BMX headtube, fork and wheel. I got it out of a skip but these bits were still serviceable so the angle grinder was employed to part it out.

    It's flexy as a flexy thing when loaded, but handles the weekly shop or one small child fine. It's best for going to the tip at lunchtime on a weekend. Everyone else queuing in their cars while I slide straight in fully loaded. Some are amused, others clearly fuming.

    I'm surprised my welds have held up as well as they have, but I give it a good bounce and visual inspection every month or so. It lives outside in the rain and the cold so it's doing pretty well all things considered.

  • Nice!

    You find 1 1/8 od tubing without too much hassle?

    I was thinking one long beam from the bb right to the front with the headtube extension going through it would be the best way to do it. No idea how easy it'd be getting hold of the material to do that though.
