Now, what was the assembled wisdom regarding lightweight race BMXs for kids who are about ready to progress to a 20"er?
I need to start evaluating options for Santa. We've done pretty well so far (a $35 12"er from Aldi, a pair of garage sale 16"ers that together represent a $7 investment). Now she can ride a bike, she'll need a bike that she wants to ride... so I don't mind putting a bit of money into a quality bike for this next stage. Budget is quite flexible.
I'm always a fan of getting more for less by buying used, if available. I'm also quite adept at adapting the wrong tool for any job into a better tool.
Obviously, there's the ByK / Fourty / etc. "sensible" kids bike option. There are still quite a few built-to-a-price features on them (for obvious reasons), and not many of them come up for sale (yet, considering that they're a fairly new market segment).
I don't know much about BMXs, except that the one I had as my first bike (from age 7) was a cheap nasty department store job. It did okay (especially later in life when it got a 3-speed hub), but we can do better than that.
Vert/street/jump BMXs are built like tanks, and often weigh more than big-wheel bikes... essentially because they're built to survive being abused by adult-sized people. So that's not an option.
But my understanding is that race bikes are quite a bit lighter and less overbuilt. As strong as they need to be, as light as they can be. Might be a good starting point - at least to find a decent second hand alloy frame and light wheelset.
What is the geometry like? They look to have very low standover, which is good. But I suspect the BB might be a bit high. They also look fairly long in the top tube - although that can be adjusted (to some extent) by the angle of the handlebars.
I know that BMXs use weird BMX-specific standards for cranks/BBs and stem/headset, which might limit options for appropriately short cranks and stuff.
It's probably a silly idea, and I probably should just get a proper good kids bike like we've been talking about for however many pages now. But... I do like silly ideas...
 from the time of the offence. Which expired this morning. Hope that taught you a lesson.
