i am planning on building a rack for a an extracycle that i am working on building. i have been thinking about making it a 2 part rack. the front part would be bolted or welded to the extracycle and the rear part i would be able to unbolt from the extracycle and bolt onto my mountain bike. i don't think it should be too hard to build the rack or mount it since both bike have a lot of parts that are similar. my main question is how wide should i make the rack or how wide is yours and how well does it work? i know approximately how long i would like to make it

Aren't racks usually hard to put on a mountain bike with the suspension like that in the back? Usually you go with a seatpost mounted rack on them.

maybe. i have never really seen any full suspension bikes with a rack. i don't see any reasons why it would not work. there are already a couple of holes for mounting stuff. if i need to fabricate a few bolt on brackets for more mounts i can. the big problem i have is when i make stuff it usually end up too big which is why i'm wondering what would be a good functional width.

i found this on instructables

this is what i'm thinking about doing pretty much

Axiom makes rear rack for suspension bikes. Although, I'd be careful as I'm sure the stays are not meant to carry much weight.

the axion website seems to to be down. i want something that could haul 50-200 pounds which is why i am planning to build my own. i am thinking about making it 8-9inches wide so that i can take my air pig with me if i go for long bike rides out in mono cliffs.

They make these things called "pumps". They're perfectly capable of producing all the air you need on a bicycle. And you can get one that fits in a pocket, if you'd rather not attach it to the bike itself. There's no need to add a rack to bike so you can carry a heavy steal thing so you don't have to work to pump your tires.

You really don't want to put THAT much weight on a rack attached to the rear suspension triangle.

i have never had much luck with air pumps. they always seem to break and i don't really like small bike pumps because they take forever to fill tires. i don't mind carrying a bit extra weight on my bike. it already weighs 45 pounds as is.
i might not put that much weight on it but i would like to be able to if i needed to.

here is a picture of what i'm planing to do for a rack
the red lines are supports and the white lines are where i will put my stuff. i figure if i keep most of the weight to the back it should not effect anything.

Well if you do it, try to have it made by an aluminum shop so its light. And I would say 6 inches is the maximum width you want to use.

crazzywolfie

it is going to be made out of steel. i don't know of any aluminum shops and i don't know any one with a tig welder. i am hoping to get my own tig welder sometime soon but for now i have to work with what i have.
