So barring a couple details… drum roll… it’s… a monster.
I painted the seat at Circle A; note the skull on the bars, the hip steering (patent pending), and coolest of all, the spider web:
This serves as both steps up to the seat and a place to put your feet.
So Adam and I are going to put a few finishing touches on it – it still likes to throw the chain sometimes – but later today we should be taking it up to White Electric where it will be on display until the auction on Saturday, so if you’re in the area, check it out.
Also we’re fine-tuning the steering lockout, so it doesn’t oversteer at speed. I’ll post some pics of that after the auction.

So we finished up last week. We’re going to try to get together for some finishing touches – a skull for the handlebars, for example – but we’re pretty much done. Here’s what it looks like:
That’s Eric and Sean stoking and Adam steering. Here are some drivetrain details:
And here’s the monster before the test ride:
So what’s it like to ride?
In a word… terrifying. So it’s got our innovative “hip steering…” the banana seat in back turns with the rear wheel, so you push/pull the handlebars to move yourself to steer.

This is even harder than it sounds.

Also, the problem with rear wheel steering – and the reason you only tend to see it on things like forklifts that only go walking speed – is that it’s not self-correcting: every time you get off straight, it wants to whip around. We’re going to install a steering block that will keep it from turning to far, as that’s how we got that taco’ed wheel early on.

But that doesn’t stop it from being a triumph. And just wait til we get the skull on there…
