The Wooden Bike Plans include patterns and simple instructions for making your own wooden bike and include a licence to make one.
Warning: This wooden bike is a prototype and has not been tested to be safe and it is there for to be built and used at the risk of the user and or builder.The above bike worked well for riders under 140 lbs at slow speeds. Heavier riders, speed or bumpy road conditions are not recommended. Wooden members should be thicken to handle heavier loads. Some images of this prototype show screws but bolts should be used through out.
Needed: two 20″ wheels (plans may be adjusted for other size wheels); wood: clear straight grain ash or hickory is preferred but Douglas fir has been used; white glue; heavy duty hinge; bolts; screws; 1/4″ nylon cord; wood dowel for handle. Drill bits for dowel and bolts and cord. The length of the wooden members are: front fork is 39″; the seat spars are 39″; the lower spars are 34″. All wooden members are 1 1/2″ wide and 3/4″ thick.
Read and study plans before you start.
Use a heavy gage hinge for front pivots. Use bolts or screws to secure hinge. hinge pin can be removed for folding bike.
Bolt is used to join wood together. If built with crank and chain join wood only at axle to maintain foldable.
Front fork.
Seat post fits into sliding seat block and can slide up and down to adjust for height.
Front side of lower hinge.
Top handle bar. Drill and fit dowel 11″ by 7/8″. Handle stem is 5″ long.
Drill and fit 1/4″ nylon cord. Knot and use quick tighten cam (you can buy these at a a shop that sells sailing supply stores) to lock onto cord. Cord is released to first knot and lower hinge is released to fold bike.
Lower rear connection showing chain engaged. For brake bolt brake arm (see through spokes).
Back side of lower hinge on front fork. Bolts are preferred over screws.
This versions of the bike show one way of attaching crack and chain. This frame worked best foot powered. Useing the crack casused strong twisting of the lower spars.
See here hinge pin being removed for folding bike.
View showing one way of attaching crank note that crank has been removed and reinserted into crank tube to enable the crank (red) frame to be rotated 180 degrees and still have the chain drive on the right side.
Here you can see the underside of the seat post support.
