wood bike frame build..PICS ADDED

[kriskros]

i am in the process of designing a construction and material app for wood bicycle.... the material will be baltic birch and red oak..baltic birch is a hardwood ply, very strong and dimensionaly stable..also reasonablt priced..a 60"x60"x1/2 shett is only $32.00..about 2/3 of aq sheet is enough.. the oak will be drilled for steering tube,bottom bracket and seat post.... a frontsteel suspension fork will be used... the frame is two matching sides joined by the oak... the red oak will also be usewd to trim the ply edges... it will be possible to design almost any shape of bicycle form..e.g, chopper,lowrider,mtb ,ect.... not very heavy...the lowrider frame i am currently working on will weigh about 20lbs max... disc brake caliper can be bolted onto the wood fork... the crrent design calls for Cyclone motor. Nuvinci hub,Lyen controller and lipo battery..when i get down to actual construction i will post some pictures

This sounds interesting. *subscribed*

Do post pics as you go.

A wood bike is definitely something I'd like to try to make at some point so I'll be watching at least.

I have a German made Klepper "folding kayak". The frame is made out of Ash and Birch Plywood. It's incredibly strong and reasonably light weight for a Kayak.

I'll be following your build with great interest

something like this ?

that is a very rugged,but crude design.....heavt,2x4s??my framewill be 1/2"x 2to 3" baltic...width will depend on battery dime3nsions.. would liketo hidebatteries and other equipment... lines will be smooth arcs

Very interesting and the best of luck with it. Remember the Morgan Sportscar? It had an ash frame.

i have a fairly completer shop..table saw,band saw,planer,drillpress variuos sanders[includind 6X89"oscillating edge sander that i built]three routers,one table mounted[my favorite weapon]in the table the router can be used verticaly or swung to horizontal position..my own design.. and may other usefull item gathered over twenty odd years... have built everythinh from a doghouse to rooltop desks...60x30,double pedestal,32 interior compartments and small drawers,,one of the rolltops i made had a jatoba [brazilian cherry] carcas with birdseye panels on the pedestals and a curly maple desk top...it was beatiful[rolltops were all joinery ,no screws,and i made my own tambours].. always had some tools , and made things for the house,kids desks,benches ,tables ect,[when i was in public school all boys went to manual training class every week]but when i retired[am now 85and i dont hand cut dovetails anymore] i got seriuos and put together a good shop.. i really enjoy starting with some odd pieces of wood and ending up with something usefull and well made...love the smell of fresh cut wood........ the bike frame i am designing will be made primarily using a sabre saw and a drill , a simple construction method that almost anybody can use

WOW!! thanks cro...that is a piece of work... might have tackled it a few years ago ... did build a couple of downhill derby type cars for the kids, they were a little smaller

Let me stat off by saying how awesome it is to have an active member of your age on the boards. Just awesome.

It sounds like you more than have the skills (and tools) to accomplish just about anything you set your mind to. In this case, the real question is going to be, is your design strong enough. And it sounds like you have a pretty good grasp on that as well.

I def wanna see some pics.

It looks as though you will be able to design and make something very interesting. I am looking forward to seeing what you end up with! You've probably already seen this thread, but I hope you don't mind if I link it here:

i do hope it ill be not oinly interesting but will make it possible for others to experiment with various shapes of bikes..and yes i have seen that link before.. thats what got my thinking started.. there are some very beatiful designs,also very complicated and difficult to makee for even an expert craftsman... still havesome experimnantingt to do... how to put steel tubesinto wood holes and prevent them from rotating...eg,steering tubes,bb sleave and seat post.. thinking about fins[1/8x1/8 on the tubes sides]matching grooves in the wood] with metal epoxy or gorilla glue.. want t avoid having to weld.. want to keep the construction as simple as possible...two fins,with some epoxy or gg spread around should provide good adhesion

This definitely sounds neat. Actually, you can find small kids' bikes like this. I work in an elementary school, and we have a selection of bikes and trikes for the little kids and students with physical disabilities. The bikes/trikes are all small and slow, but they help kids to learn coordination, etc. It's mostly for the occupational therapy program. I occasionally visit the room where they are stored and fantasize various ways to E-bike them. Some could be converted and be really fun little racers.

Good luck to you, and remember what they say in the extreme sports world: Pics or it didn't happen.

 

[REdiculous]

These days you gotta have HD video or it didn't happen - pics are so late-90s. lol

Hey Mike,
my 4 year old has a wooden danish style bike without pedals (balance bike), and I am thinking of a small out-runner friction drive (Kepler Drive) to do just that....

.. basic layout of the pieces...frame is 1/2"x 2 1/2"balyic birch ply,expande as necessary... the seat post is two piecesof ash,3 3/4x 1 1/2, grooved for the seat post tube and rebated at each end to ..this is just a basic loyout tyo show the pieces ..the ends of the seat post are rebated to take the front section...the add on end plate[1"ash] is becazuse the rear dropout[3x3x1/4] is recessed 1/4"in. ...d bike1.JPG[/attachment]......this just a tempory clamp assembly to shgow overall bike... frame 15" at the seat postand 50"overall...the bars at thend[jatoba] are supports for the rear carrier...front wheel will be 24" mounted in a cut down chopper fork...rear wheel will be20"with a nuvinci hub... motoe[1200watt cyclone]will be mounted behaind the seat post and the battery will be in the front frame section.. .. this shows hor the sections go together.[all overlaps are 4"]..the front section fits into the rebates of the seat post....the supports for the rear carrier come next followed by the the rear section...this makes the space at the top of the rear forks 41/2"[3" for the post.32/4" for carrier suport and the rear forks./ at the bottom of the seat post there are two spacers 1 3/16 to make inside rear dropout width of 5 3/8". these pieces are glued and screwed into the seat post. ..these are some the parts...the steering tube is made by grooving a piece of 3 3/4x2"ash to take 1 1/8id steel tube...1 1/2"x 1/8 straps are welded to the tube and recessed into the ash..this assembly will be BOLTED in between the ends of the front section..the bottom bracket was macined from stainless steel[73mm]..there are two splinesinst on the outside of the tube...matching grooves are cut into wood mount....this willpreveednt e bottombracketfom rotating under pressure...this assembly goes int the lower front section,where the holes are.... this type of construction makes it possible to design almost any shape or style bike you want...more to follow as i progress ent]

Hey, I thought you might find this article on the rennholz wooden electric recumbent interesting.

Uses a Bosch drill for a powerplant.
