SUV bikes?

Hello,

I was looking around on the Surly website, and found a terrific
looking bike called the "Big Dummy" [http://www.surlybikes.com/
bd_comp.html].

It appears to be the SUV of velocipedes. Does anybody know of similar
bicycles?

This is THE pedal powered SUV:

Is there a decent picture anywhere?

not sure that lean-only steering is that useful.

Here is one set up as an rickshaw:

Thank, useful
Yes, seen the design before.

I built a copy of one of these, and use it quite a bit. Yes, the lean
steer makes for a wide turning radius, and I needed to add inner-tube
bungee cords to help pull the front end back on centre after turning.
But the biggest improvement was adding electric assist, because I
often have to carry 200 lbs. of gear:

What would I change? I'd thought of going to a fixed-boom flex-chain
FWD set-up, but that'd be a lot of effort, and the beast has worked
well over the past five years. I'll think about changing it if the
thing ever needs to be rebuilt.

Does it stay on centre/ahead once you have it there, or tend to turn to
one or the other side? Is that response load affected?

thanks. Very helpful.

Yes, it does stay centred, but that does depend on the amount of road
crown (some of our roads here in Ottawa have a fair bit of that). The
bungees more or less eliminate the crown issue. The response does not
seem to be load affected.

You're welcome. There's more at my blog (though not a lot of posts on
it in 2008): http://drumbent.blogspot.com/search/label/trike
