Introduction: 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 1: Gather Materials
Connectors
- 5 White
- 36 Yellow
- 45 Orange
- 16 Green
- 4 Red
- 4 Light Grey
- 16 Grey
End Connectors
- 16 Brown
Rods
- 4 Black
- 9 Grey
- 27 Red
- 2 Yellow
- 4 Blue
- 65 Green
Miscellaneous
- 2 Red Gears
- 12 Blue Spacers
- 26 Black Chain Link
- 1 small rubber band
Motors and Wheels
- 2 Small Tires
Step 2: 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!

Interesting, but does it hold people up?
Reply 13 years ago on Introduction
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
