The
Speedbowl, part 1
| After Fred and I returned from California in October last year
he told me that his next bike would have 23 inch wheels on the front
and back. The manufacturer of the 23 inch tires (Veerubber) had
promised to donate a set of tires and Fred asked me to make a matching
set of 23 inch wheels. He wanted them to have 4 spokes like the
wheels used for racing bicycles (see examples in pictures below).
|
| I made a couple of versions in CAD and Fred chose the top left
style. He wanted a very special brake system with a half brake caliper
on each side of the wheel and hardmetal discs bolted to each side
of the rims, making the whole wheel into a brake disc! I completed
the CAD models for wheels and discs and the CAD-files were sent
to a machine shop where each wheel was machined out of a solid lump
of aluminum. |
| The wheelsand brakes are definitely not the only unique thing
on this bike, Fred designed and built a front fork from scratch
with the suspension inside the steering neck! The oval tapered fork
legs are works of art and the lower fork tree is made of 3 thin
plates instead of 1 thick plate. |
| In the pics at the bottom of this page you can see the mockup
of the bike, a brand new Panhead engine, 4-speed gearbox, oil in
frame as usual and beautifull classic boardtracker lines. Check
out the cardboard wheels! |
