24 inch wheel frames

Oh, WOW, not a single reply for 9 days. That shows you the problem here: building a 24" or 20" kids mtb is a hard task, because there are hardly any components available.

I like building bikes, for me and for my kids, but when I got to 24" I ordered a Woom Off 5, copmlete. If I was insisting on building such a buy, the result may have cost more, and weighted more.

If you still want the DIY method, you can look for a carbon frame from Ali Express. Don't crucify me for this suggestion, we all understand the pros and cons of an Ali-Express adventure. It's just an option. Example:



As for the specific measurements: I don't think it's THAT important for a kid. He's not going to race this bike on the Great Divide, riding 200km a day. Short chain-stays are important, the good quality kids-bikes brands will have them (Woom, Spawn cycles, Early Rider)

Your next challenge, after the frame, will be the fork. Again, There are some carbon forks in Ali Express, and even some suspestion forks can be found.

Rims for the wheels will also be a challenge. It depends on the kid's weight and how much he's a "shredder". There are many factors here: weight, width, number of holes. So it might be hard to find the specific set of requirements as a seperate component.

Sometimes Spawn cycles have pre-built 24" wheels.

Anyway - good luck with the project, and post some photos when it's done.

Thank you for all the replies!

Yes, I believe woom would be the most cost (and time!) effective 24 inch if you don't have already parts around.

I already built a 20 inch earlier for around 1,000 $ at the end, and plan to move those parts to the new one.

There I learnt the original (600$) budget is easy to go over... Main reasons for over budget were the super light wheels from Alibaba to be replaced because rim width was too narrow and MTB tires felt unstable on it and impossible to fit properly, plus I repainted the frame.

Thinking for the future I already have an RST f1rst 24 inch wheel fork which is only used these days once we go to a ski slope which operates as a bike park in the summer.

So I have the parts, needed only a frame and wheels. I'll build the wheels, Alienation deviant rims with koozer 36h hubs, DT db spokes, already bought them, built similar for the 20 inch bike.

I expect I will end up again 800 grams heavier then the woom, but more gears and shimano brakes and drive train. Which is not necessarily a good trade off, but seemed to be a good idea when I started the 20 inch project when I expected again, the frame will be lighter... (Gary Fisher Cosmo, 1578g)
