This is my beloved Woody. By far my favourite bike to ride of all my bikes. I dont have any photos of the build so all I can do is show the finished product. The bike was constructed from a bit of 4x2 recycled hardwood and a 5 speed 20' kids bike. The vinyl I used to cover the seat cost $5 and that is the total cost of the bike.

The bike rides really well but it tought me a couple of things about frame geometry. When I ride up curbes slowly my bike tips over backwards. The center of gravity is too far back by about 100mm or so. And I would lik to be able to stretch my legs about 100mm further. I might have to invest in a CAD(https://www.instructables.com/id/Office-Chair-Bike/step1/Design-your-bike-using-a-CAD-system-Cardboard-Aid/) system.

The timber got a coat of sanding sealer and 2 coats of marine varnish.

I also added custom lightning bolts and a scull.
Are your knees over the handle bars?
great idea HanzieO and good looking too.
I installed new handlebars today to bring them closer to me. I was a bit crouched before. I installed new purple brake lines and also conected the back brake with brand new brake pads all round. <br><br>I feel much more comftable riding and stopping is much less scary.
Sweet bike. Can you say a little bit about how the back wheel is attached? Is that the original chainstay etc. under wood? And then the front wheel seems to be just a snug fit with some epoxy putty to strengthen it? Great idea with beautiful execution.<br>
Hi you are correct the headtube is just a tight fit and some epoxy resin.nThat was a bit flexy so I drove about 15 woods screws into the joint between the timber and steel tube. That helped some. Then the layer of epoxy putty on top helped stiffen it up good.<br><br>The rear end I cut the original seat stays of just above the seat stay bridge and the chain stays I left about 100mm long. Measured from the dropouts. The seat stay bridge is screwed to the back of the bit of 4x2 and the triangle piece of plywood is screwed over the top.
I still need to install the back brake cable.
think about doing a DOUBLE front brake.<br>the higher speeds, and lower center of gravity lets you brake more like a motorcycle, and less like a bicycle.(70% front, 30% rear. give or take)<br><br>Although, your design sits pretty high, so maybe a double REAR brake would be better.<br><br>Any way you look at it, more braking force is better.<br>With the same leg power, you'll be traveling faster.<br><br><br>What IS that you've used to affix the headtube into the board?<br>I don't see a split-and-clamp design...I'm thinking it's JB-weld?<br>Is the seat the same 2x4, ripped down to 1x4 dimensions? or is it scrap plywood?
It would be interesting to see a profile photo of you riding on the bike so I can understand how easily you can reach the handlebars for steering. Thank you for sharing.
