Given that I would probably just buy a cheap balance bike (can get them for ~£20 on FB) for the wheels, am I just going to end up with a heavier, splinter-y version of the bike the wheels come off?
Specific Qs:
Am I likely to be able to make a wooden framed bike that weighs ~3kg that most metal framed ones seem to weigh? (I know I can do the maths on this, just wondering if anyone has any quick answers)
Any suggestions on geometry/sizing from anyone in the know? Feels like a silly Q, but head angle? Reach? Bar height? Planning on saddle with adjustable height (in increments).
I think it’s a great idea!
How cool would it be to have your first bike made for you by your uncle? 😊
So much better than an off the shelf thing.
Never made one myself but there is no reason you couldn’t keep the weight down.
The guy in the video looks to be using softwood/shuttering ply, which is lighter but can suffer from warping and larger voids in the material. The Instructable guy uses Birch ply.
An alternative and quality ply is Garnica Efficiency/Poplar Ply.
Very light. Used in campers a lot.
Downside is it’s 3, maybe 4 times the price of shuttering ply depending where you go. Garnica Plywood
You would need to reinforce appropriate sections but yeah. Cool idea.
Do it and carry this thread on 😊👍
Who was the clever chap who made a metal balance bike on here? I’m sure he’d know a bit about geometry. 🤔
P.s. I work with wood/ply a lot and am always very happy to help out where I can if you had any questions during the build. Just pm me 👍
I’ve toyed with this idea as well. Given how much time you’re likely to spend carrying it, I would prioritise lightness! I would imagine a plywood bike could end up pretty heavy unless you’re quite efficient with it.
Great idea! Thinking about it, my neice is due her first in a few months, so I’ll have to get busy…
If using Birch Ply, timber yards often have offcuts in decent sizes for very decent prices. My local sawmill, had 18mm grade AA at £7 for 450 x 1220. a hefty reduction on the cost of a full sheet, and a helluva lot easier to handle.
My kids had a wooden BB (bought not made) that was ok, but eventually we marked due to rain. Also weighed a ton vs the Hoy one we also bought. In the end the Hoy one won out because it was light, much easier to get going and had a brake for skids. As always the romantic notion of kids enjoying wooden toys falls by the wayside when they make their preferences clear (cheap plastic flashing noisy tat FTW!)
As someone earlier said, all balance bikes spend at least 50% of the time being carried, so maybe design it with a D Loop on each end to attach a strap. Also my kids loved the wooden one because it had ‘downhill race bike’ triple clamp forks. Lol. I think making making their first bike would be great. Shame The Bicycle Academy isn’t around, then you could have spent £1k learning to weld them their first one.
We had an Earlyrider to start, looks cool. I like the idea of building one. Agree about weight – I used Garnica for my van furniture. Good looking stuff, although it can have voids in it.
Geometry geeks might have some guidance on angles.
I helped one of our students build a wooden bike a few years back, it was essentially two identical laminations in ash, for the main frame elements, with some custom dropouts. We re-used the seat tube/bb and modified a headtube to bring it all together. A similar approach, possibly just using the upper frame element might make a super balance bike.
I built a wooden push along trike years back for my nephews. I even made wooden wheels and axles / steering head were made with plastic pipe and wooden dowels. It was very crude but they loved it and loved the fact I made it.
So to OP even if what you produce is not as slick as the bought ones go ahead anyway.
I bought a Lidl wooden balance bike (18!) years ago for my youngest as it had decent pneumatic tyres and ballraced wheels for very little money.
It was very tall (you’d have to be about 3 or 4 yrs old to ride the thing) so I made a new centre section from birch ply to drastically lower the seating height. Everything else got re-used (forks, handlebars, rear wheel sideplates / “chainstays” etc). As he grew I could drill extra holes to reposition the “chainstays” so it still fitted.
It got heaps of use and was very battered once he’d finished with it so immense value for money. Still got it in the garage so will take a photo later.
Then there were also the two STW forum projects I did for oversize steel frame balance bikes 🙂
Here we go. This is in the final height setting at which point he moved onto pedals. Looked like I also drilled the fork to run the front wheel 25mm lower in the early days. Original Crud guard to keep him out of the back wheel.
Construction is well under way, and going well! I’ll share pics when done (realistically after Christmas).
Those of you who have experience with balance bikes – I see some have little foot rests (or even just grip tape on the chain stays) for when scooting down hills – is this helpful, or does the kid just bash the inside of their legs on them? If I did have them I would make them removeable.
