(Originally posted to the HPV list, but thought there might be some
here that don't subscribe to that)
My 1996 Linear LWB is out of commission, after developing a large crack
in one of the chainstays. Details at my blog:
http://drumbent.blogspot.com/2006/08/bike-broke.html
Being aluminum it is not repairable (well, I'm not going to trust
anybody's welding on it), but since this is a folding bike the rear
section only attaches via quick-releases, so there are options for
ressurection. Just thought I'd pass this along for any current Linear
owners, especially if the bike has been in service for a while. The
crack happened in a high-stress area under the seat, right after the
curved plate that joins the two stays, so I would highly recommend
keeping an eye on this area.
And while I ponder the Linear's fate, I'd still prefer to have a bent
for my long rides, so my brother Mike has offered me the use of his
Infinity (remember that brand?). He bought it before I got my Linear,
so I did spend some time with it in the past. Mike now has a
Streetmachine, and the Infinity has languished for quite some time.
It'll be interesting to ride this last of the factory-built
cable-steered bents...

Hi Bill,
I would be honoured to receive that, since I imagine it's from your
famous Linear test-bed machine! I've acualy been toying with having a
friend make a version of the rear suspension you came up with for the
Linear, but that might take a while. I'll email you off-list...
Thanks,
k

What is next; an Avatar 2000 followed by a Mochet Velocar? ;)
Will the current folding Linear parts fit:

As an aside, late in the last century I stopped at the scenic pullout
[1] in Guttenberg, Iowa. The Guttenberg Chamber of Commerce brochures
available in the tourist info kiosk mentioned that Guttenberg was (at
the time) home to Linear, "The World's Most Comfortable Bicycle".
