Introduction: K'nex Bike

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 1: Gather Materials

- 5 White
- 36 Yellow
- 45 Orange
- 16 Green
- 4 Red
- 4 Light Grey
- 16 Grey

End Connectors
- 16 Brown

- 4 Black
- 9 Grey
- 27 Red
- 2 Yellow
- 4 Blue
- 65 Green

- 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!

I didn't bother about making it, so, I ask: can a person fit on it? Please answer my question. If you cannot, I don't mind. have a nice day. I might wont to change my name into: K'nexasoar".

Interesting, but does it hold people up?

Nope. You can feel it bendy when you push on it but it looks soo sweet.

Bartboy (author)Trauts2008-09-26

how much weight can it hold? necause if it can hold at least 50, you could put a little kid on it

DrWeird117 (author)Bartboy2009-01-25

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...

Trauts (author)Bartboy2008-09-26

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

Bartboy (author)Trauts2008-09-26

rienforce it

GoCubs252 (author)2008-12-21

I_am_Canadian (author)2008-08-11

Nice idea. I made a bike for the knexpert search... I lost though.

The Jamalam (author)2008-08-11

Sadly, there's not much point in entering it in the book contest, it ends today

paperninja (author)2008-08-10

lol would be cool if it had training wheels and a motor =p

Whaleman (author)paperninja2008-08-10

If it had a motor, then why go through the trouble to put a chain and pedals on it?

danymw (author)2008-08-10

looks good,i tryed to build small bikes,but didn't worked. try to ad suspensions and resistant wheels
