trike attachment?

Anyway- Steve, trike conversions are sold by a few bike shops here and
there. Since you don't say where you are, I can't refer you to a
specific shop.
I plugged "bike trike conversion" into Google and found these:
http://www.web.net/freedex/Trike%20Conversion.htm
http://www.megalowrider.com/Item/F9901.htm
http://www.masterlowrider.shoppingca...441/135896.htm

The conversion housing and associated parts are also available from
J&B Importers- but there doesn't appear to be a complete kit listed.
You'll have to talk to a knowledgable dealer to get all the parts.

One consideration to keep in mind; the cheaper kits generally are set
up to drive only one of the rear wheels, and while that works, it's
not necessarily as good as using an axle with a differential that
drives both wheels. One-wheel-drive is, however, vastly preferred
over a straight axle that drives both wheels; this is not a safe setup
for a trike, as it makes steering very dodgy...and downright
impossible at times.

I'd ask about the type of system used before buying any kit.

Most purpose built delta trikes drive only one rear wheel. A
differential adds significant cost and complexity.

It also adds another drawback; unless the diff is equipped with a slip
brake (in automotive apps, this is called "posi-traction") the
effectiveness of the drive will be completely lost when *either* rear
wheel lifts off the road. With one-side-drive, you only lose drive
effectiveness when the driving wheel lifts. There are reasons to
prefer each of these, but when cost is taken into account, the
one-siders tend to win. I had a one-sider as a delivery vehicle back
in the early '70s; I don't miss it.

And there was I thinking it was called a limited slip differential :-)

It is, if you have the time, but if you're really in a hurry it's just
"posi". (Car racing fanatics are in a hurry a lot.)

Another approach is to use an axle with no differential to drive both
wheels, but to use freewheeling hubs. This allows the inner wheel to
coast while turning, but delivers power to both wheels in slippery
conditions. I know of one homebuilt delta trike using this arrangement.
