Kids 24" Mountain bike, Dirt jump project?
#1
Hi,
I got this 24" wheeled kids bike cheap, I’m thinking of making it into a dirt jump type bike is this possible? I’m not too sure of what frame geometry a DJ bike requires but in think what I have read so far is that the reach to the handle bar is important. Also I dunno if the frame and fork can take the abuse. does anyone have any suggestions are hints, the bike is a Carrea blast 24 disc spec 2009 (I think) with a RST Capa t8 fork, it is missing the wheels and a brake.

I’m thinking of removing the paint from the fame and fork and polishing them like I seen someone do in another thread. Then in the distance future have it kited out with hydraulic disc brake's and single front chain ring with a derailleur on the rear. What’s everyone think?

Looks like a nice frame with ok front suspension. As far as dirt jumping I am not certain how 6061 aluminum material would hold up??
Good maintenance to your Bike, can make it like the wheels are, true and smooth!

i was thinking maybe that 6061 aluminum would not be suitable. it is a really light frame i weight it at 1.75Kg but dunno how accurate the scale is. i'll do some online research to see what i find.

#1 are you sure that there are no cracks in the frame?

Easy way to determine is tapping it with a really light (like 50 gram) hammer and listening. Tap lightly all over the frame, no more than 50mm between each tapping location.

Aluminum frames can develop cracks when abused, and a crack can lead to catastrophic failure at the most inopportune time.

i haven't giving it a real close look yet, i didnt know about that hammer trick i'll try it. the bike does look a bit abused lots of strips all over it.
