Picture of K'nex Bike
A simple bike made out of K'nex. It would have been a larger, two-speed model, but I couldn't get a hold of any of those larger yellow gears. I also don't have enough bendy rods, so this bike is made with 100% old school pieces. It has an adjustable seat and handlebars.

Step 2: Wheels 'n Things

Picture of Wheels 'n Things
Build the wheels, support struts and supporting components. The wheel shown is the front wheel. The back wheel is different, so build the wheel without the supports for the back one. The wheels are a tad weak, but you can substitute yellow bendy rods in place of the orange connectors to form the curve.

Step 3: Front Portion

Keep on building!

Step 4: Gears 'n Things

Build the gears 'n things. The brakes are nonfunctional for now, but I'm planning a two-speed model once I can get some yellow gears. If you can get the brakes working, please post a picture!

Don't use yellow gears cause they have little nodges on them so the chain wouldn't fit cause i tried that on ma go kart i am makin

Interesting, but does it hold people up?
Nope. You can feel it bendy when you push on it but it looks soo sweet.

how much weight can it hold? necause if it can hold at least 50, you could put a little kid on it
I sat on one of those TINY bikes (made for, like, 3 year olds) and peddled it up and down the aisles of a Target. Wow...I couldn't steer straight, knees kept getting in the way...

Lol, no. It can't hold more than like 2 pounds.

lol would be cool if it had training wheels and a motor =p
If it had a motor, then why go through the trouble to put a chain and pedals on it?
