Nice idea. A smaller rear wheel brings your load closer to the ground and this means more stability. Now, can you please post a picture of this bicycle on a flat ground ?

Um....... I'd have to find all the parts and put it back together again first :o

Cool! Very nicely done Badmother. I like the way you've used the two standard bicycle racks.

ChiapasFixed's new beauty should be noted here.
It's a cool bike.

Oh my word, - that bamboo bike is seriously beautiful. Superb workmanship :D

I need one of those rear triangles!

edit:
Oh my god, that thing is stunning! I am in awe.

Looking Good
 

This is the way to do it. (Instead of running the tibe to the top of the seat tube) Triangles. They are the strongest shape. It may not seem like it, but this way if done properly, will be strongest.

Im planing on building one nekt month. I think Ive got most of the parts lined up and I'm really excited. I also plan on welding it once I get it all working properly. (Sometime in the fall mare then likely)

O hai! Can I play too?

Built it up in an afternoon, single speed though I could shift rings manually. One brake, up front. There's still a brake lever on the handlebar I used for the brace thing... But who cares? Long bike is loooooong!

In 2003 I went to Ghana, Africa, to establish a school for cargo bike design. My first step was to build and test each kind of cargo bike that I could think of, about 25 in all. Then after testing them in the bush we found that the xtra-cycle style could maximize load given the single-track jungle terrain. So now the school makes them for the government, which is trying to aid farmers in getting Ghana's rich natural resources to market:

That deserves a thread of its own, seriously.

Wow, Johnny, sounds amazing, I would love to hear and see some details.

Anyone thought of using a tandem bike frame?

maybe a dumb question.....but are Xtracycles typically SS?

No. People don't like singlespeed bikes for carrying 500 pounds of stuff up a hill.

ownage
 

xtracycle what a cool idea, by what I see a xtracycle is for big loads and so on yes? I want one lol I have this to work with, and a three speed ballon tire bike

they are mounted by bottom bracket right? the bike i'm using, the red one has broken bottom bracket, so it might be no good, but i'll just weld it lol

Mine
 

This is my first, mind you both bottom bracket are broken and stuck in there but i'm gonna remove them, I might use other frame, classic possibly

with two bad bottom brackets it rides very bad, but the rear one will be fixed and the norco one is stuck busted so i'll have to use another bike for the front

Well... I've collected my donor bikes and went through this thread for the nth time to see what everyone else has done before I start building mine.

This will be fun.

My pond is getting famous... :D

Extra
 

BUM BUM BUM! my working extracycle jut need long wires lol

Well... I put the frames together tonight and now need to set the ride height and brace things before my friend tacks in a few welds to make things really solid.

I took a few pics and will post them when I get home from the shop to see what people think.

The adventure begins...

Nice, I like mines colors, looks kinda neat, well how it is now, i'll post a pic, you used a Norco, another poor norco will have a Xtra life, mines made of three of them lol

It's a truly Canadian ride being that the bikes are a Norco Katmandu (straight gauge chromo) and a CCM... I have a rear wheel built up with a 4 speed cassette and think that will serve me well as it has a wide range and the cog position is very central which should reduce chain deflection.

The grey and black looks good together and I have a mountain of steel and a huge parts stock at the bike shop from which to draw any materials I need to finish things up.

I am pondering running a 24 inch wheel too althouhg I would really like to have dual brakes as it will be a hauler.

I hope to be riding it at the critical mass this Friday although I may not have it racked up.

If you do your gears like mine, mines a 21 speed, and use both shifters, it runs just like a normal bike, infact, they pick up speed pretty fast, my scrap steel is inocent bike frames lol, both breaks is a need, mine really needs them, if it was front the forks would proberly break, , i'm making a trailer for it to with breaks on it to
