My nine year old had a really nice custom 20 incher that I built for her a couple years back. Then she had a growth spurt and it didn’t really fit her any longer. So I promised her a custom 24 incher and gave her 20 incher to her cousin for Christmas.
I have most of the parts to build the 24 incher, but it takes time and motivation to build frames. I’m running low on both of those right now.
Anyway, my kid was mad she didn’t have a bike and I wasn’t sure if I’d be able to build her frame any time soon, so I just snagged this bike off KSL so she would have something to ride.
I was in a rush because it was raining and I was on my lunch break so I just paid the guy and tossed it in my truck.
Once I got it home, I realized it was not an aluminum frame— those giant tubes are in fact steel— and it weighs 37.94 lbs. My kid only weighs 54 lbs.
I was starting to regret my decision. In order to assuage my conscience and have some fun, I decided to perform an experiment— how rideable can I make a $250 (retail) Walmart bike using crap from my garage and the Bicycle Collective? Setting a budget of $100 so I don’t lose my a$$ when I go to resell.
First pound lost was ditching the reflectors and installing a non QR seat binder, replacing the steel seatpost an aluminum 28.6mm one from my junk pile and adding a random 1993 Vetta Gel saddle.
It has a 3x7 drivetrain, so next up was making it 1x. Ditched the front derailleur and shifter. The cranks were 152mm long. I feel that’s too long for a kids bike. The drive side crank arm had all three steel chainrings swaged to it, so there was no chance of removing two of them. I tossed an old set of Shimano STX cranks in the mill and went to work.
Now I have a set of 140mm 1x cranks. Saved a ton of weight here.
Final weight for the bike was 35 lbs for an afternoon’s efforts.
Looks like I’ll need to buy a BB. I don’t have a short enough spindle in my junk pile and the chain line is way off.
Next I will address the six pound suspension fork…
