Please help fund the development and construction of WoodBike v1.5...
seen a few wooden bicycles on the web, and I've wondered for a
while about wood as a bike-building material, too. Wood can be
just as strong and light as many of the modern composites, and
it's often easier to work. The question is - Can I do it? Can
I build a reliable, practical vehicle? Well, I plan to give it
a good try.
My main goal will be to start
with building a light, but strong, short-wheelbase, under-seat-steering,
recumbent frame of marine ply, with welded steel dropouts and
head tube, then start looking at improvements to the design and
componentry. I plan to use a standard chromoly fork and alloy
spoked wheels to start with, but if the machine works well, I'll
try building timber wheels and fork, too.
Anyway, here's my starting
- Initial spec: 20x1.25 alloy
rims with stainless spokes.
- Final spec: 20x1.25 alloy
rims on ply 3-spoke front and ply disk rear.
- drum brake hubs.
- Marine grade ply and laminate
(various thicknesses.) shaped and hollowed for optimum weight
& strength. All joints to be epoxy and screw bonded.
- Welded steel couplings for
- All timber to finished with
a heavy duty, clear polyeurathane over dark stained "points".
- All interfacing metalwork
to be brushed and polished to match wood grain direction.
- Initial spec: chromoly unicrown
with A-head style steerer and head.
- Final spec: timber fork legs
coupled to chromoly crown and steerer.
- Initial spec: whatever comes to hand.
- Final spec: probably Shimano STX (as much
as possible, anyway.) preferably 24 speed.
- Lightest, strongest available chain.
- Weight Targets...
- Initial spec: <18kg.
- Final spec: <14kg.
- Future designs to approach 10kg mark.
