But would you ever use it? At 52Kg I'm not sure I would. Does look
nice though, I must admit.

Imagine having to change the tyre...!

Oddly enough, was walking back up to King's Cross and the train home
last week (after peering at the recumbents in the BikeFix shop -
again !), trying to figure out how to go about constructing a braced
plywood boxframe 'bent - if Marcos can use it for a lightweight
sportscar chassis - http://www.midlifeclassics.com/marcos.html - then
why not ? At least on the bike you can't set fire to it by fitting the
wrong exhaust :O)

Wobbly John has one built a wooden bent from plans available for $25
from the US. Which reminds me I must dust them off and get a project
started.

Another version of the same bike here:

(and other wooden ones on http://www.manytracks.com/recumbent.htm)

Kudos to them for having two 700x32C Marathon Slicks left (apparently they
have been discontinued), some of which they then lose for the minion who
carefully brought me a Marathon Plus, told me I wanted the Marathon Plus,
asked if I'd considered the Marathon Plus, told me again I really wanted
the Marathon Plus. We did this all the way to "Look, I want to buy _these_
tyres I am holding. Are you going to sell me them or not?"

Good wooden structures have a better strength/weight ratio even than carbon
composite.

Yes, that particular one is heavy.

Hardly surprising, as he appears to have made it completely solid. :)
I'm tempted to get stuck into that sheet of plywood I've had sitting
around for ages with a jigsaw and router, but I've too much other more
important stuff that never seems to get done ...

I'd dispute that. Even quite moderate (not especially special) CFRP
could have a strength of around 3000 MPa, with a specific density
about 1.6, so more than 1800 MPa/density (unconventional units, I
admit).

Spruce (pretty good strength:weight - popular in aeroframes, eg
Wright Flyer, Mosquito, Hughes' behemoth) about 75 MPa and density
just over 0.4, that's 190 MPa/density.

What wood do you believe has strength:weight ratio ten times better
than spruce?
