Cheap bike rack

Cheap bike rack
This project was part of an undergrad design class where we wanted to make cheap bicycles more utilitarian. My goal was to make something that you could produce in a dorm room, but would hold 3 people.

I used a 3 speed, gear-hub, girls bike, but you could probably adapt the simple design to work with any bike. The end result is pretty goofy looking but very effective at hauling people and cargo. You can find a bike like this for $15 at goodwill and should plan on spending $10 on the bolts and wood.

take a look at the cull-lumber pile/cart also, check some of the other dimensions, one near me had some 8ft 2x3 for less then $2 each. or just scavenge from pallets or something- you don't need anything pretty for this

i really like this design!
i made a quick one that was good but it swayed too much while i was riding.
i recently lost my bike was and with it the rack so im starting over , the only piece i like to add is ,with my old rack and i think this one as well,
loading them is a problem because the kick stand isnt meant to balance something that top heavy and they are unstable.
my idea is to find some sort of two sided kick stand , like they have on mopeds but other wise im lost.
any ideas

they sell these. try rivendell bicycle works' web site. I admit this may not provide the cheapest example, but if you search for "kickstand" you will get the item(s).

any trouble with the bamboo sticks rattling out while underway? looks very nice and secure overall.

This is a great idea. I used your design to build my own version that you can check out HERE Thanks for the inspiration.

Sublime! A truly revolutionary idea because of it's simplicity and the measly material resources needed to realize it. Well done!

love the innovative/lateral thinking. (also, you know you can easily create "notes" in the images to help explain things... easier than photoshopping in lines and soforth)

I love it!!! I'm going to try and make one Wednesday. I've been looking for a good soplution to carry copy boxes / food deliveries. Has anyone tested this out? ~shep

I can't wrap my head around this thing carrying people, or actually cargo either. Is the cargo just to be strapped onto the wood? and the people too? sounds less than comfortable. a picture or explanation would be wonderful. And I think it's awesome that you're studying this kind of thing in school!

One of my favorite Instructables...and so underappreciated. I plan on attempting to build this tomorrow.

Very very neat! I wonder how much cargo can one take on this thing?? Sometimes you see people in parts of the world carrying in one bike cargo that would fill the trunk of a large truck!!!

Nice design. I often follow existing designs for racks (and then get to use the bolt holes for such purposes). This is really innovative. I also like that it can be adapted for use as a framework for attaching decorative woodwork, or a cowling (did I hear repurposed tent with shock-corded fiberglass poles?). Add to that the whole hand-tools-only approach and it's even better. Wow!

It would be great to see a picture of this hauling people and cargo. ? L
