Tom Spollen's Tiki Bike, part 1



Specifications:

42" wheelbase
weight distribution 60/40
20" shock absorber
Schwalbe tires front & rear
weight: approx 32 lbs.



This is how it started: a $15 frame courtesy of Rich Sadler. It was probably a 10-speed mixte from the 80's. The twin tubes on top will supply the seat support and determine seat height. Now begins the process of conversion to a recumbent.



The seat will be designed and fitted first; only afterward will the boom (leg length) be determined. Here the plywood (double gauge) has been glued together; corner braces from the local hardware store are holding it together.



Now the seat has been reinforced with fiberglass.



This wooden fender will channel road spray. Foam pads are fitted. A spare chain stay from another bike is supporting the seat back. Later it will be replaced with aluminum.



Better view of the seat development. All of this wood looked "teaky", hence Tiki.



Reinforced strips being glued to the seat. Note corner brackets.



Epoxy sets up best at 75 degrees. Our house is 59 degrees F, therefore we had to wait two days for this process to set up.



This is a 42/32/22 triple crank usually used on mountain bikes. Our quick fittings indicate the boom should be 17" in length. Here it is just before welding.



The frame has been welded, ground and painted. The paint is Rustoleum high gloss white. We gave up spraying because it gets into the forced air heating system. The brush also puts down a thicker coat.
