+1 on Nexus. Choose your front chainrings carefully. You probably wouldn't even need more than two. If you haven't checked out Sheldon Brown's website, he has some great info about the Nexus 7/8 that will help you decide how to set it up.

FWIW, my setup is a single chainring in front and Nexus 7 in back. I don't know the size of the chainring off the top of my head, but it is "medium sized." I ride it to Costco and back with a hill in between (uphill both ways ;D) and I don't have a problem with 50-70 lb loads.

From yesterday... will be keeping the studs on for a while yet.

(image unavailable)

While I was at the shop I gave the chain and drivetrain a good cleaning and changed out the Suntour Vista derailleur for an Exage Mountain that I had just rebuilt.

Shifting got a little lighter and I knocked a few hundred grams off the bike's weight...

I start building my second Xtracycle. For now I have a doubt. I wanna weld a tube between main frame and rear triangle.
What tube will be better? The green or the red? I don't have a green tube long enough, so I'd prefer the red one. It will be strong and stif enough in that pozition?

You'll need two tubes. The first is to replace the missing seat tube from the donor bike. Without it, the rear triangle will just spread until it breaks. The second goes from the top of the donor chainstays to top of the main frame chainstays, not horizontal like your red line.

You guys inspire me. My buddy gave me a sunburst-looking rear triangle from an old aluminum Cannondale. Viola! Cargo bike. It's the coolest bike I've ever had. People stop and stare when they see my kids riding on the back of this thing. I can't wait to pack a pig out of the woods on it. Next project: plywood Long John

Nice bike, Forn Man!

Has anyone on here made a poor-man's stoker stem (to put a handlebar out towards the back) by cutting one end off a threadless stem and sticking a quill stem down into the hole left?

I'm wondering if it is possible. The aluminum seems plenty thick, even if I end up having to bore it out a bit.

Alternatively, I'm thinking about taking that same threadless stem, cutting it in half, and lengthening it with an internal or external sleeve. Any opinions?

FornMan - love the foot pegs on the bottom bracket of the donor rear triangle - very neat.

Home built xtracycle

Thanks everyone for the kind replies!

badmother: Yeah, I lurk a lot more than I post. I feel like an idiot if I haven't actually built anything. I guess I'm still astounded at the internet in general. I'm still using it like huge library, mostly.

johannrissik: That's my new favorite bike to look at. Isn't it beautiful? It's every bit as elegent as a plywood kayak or kit airplane. I've got to try making it. I've still got some boatbuilding epoxy from a while back.

Have re-read this thread from the beginning... again.

Stretch has been resting since winter ended and I have not even gotten around to swapping out the winter tyres yet... I think the risk of snow is long past so should do that tomorrow.

And I have been collecting parts...

Here is the latest on my BEER RUN Rat Rod Utility Bike

How do you like my BEER RUN utility bike? I am building it as part of the Rat Rod Bikes Build Off #6.
The skateboard is the actual seat (with the option of putting a normal seatpost and seat if wanted).




You can see more on the bike at:

Sturmcrow: My little one complained that she wanted something better to hold onto other than the seat post or my back pockets, so I made a mini handlebar from a cut-down handlebar and an adjustable threadless stem. I had to shim the seat post with some metal from a Pabst can, and I protected the stem and the post with a layer of electrical tape.

Also, I replaced the old skateboard deck with a snowboard that's quite a bit longer and more attractive. I'm considering ways to utilize the binding mount screw holes to improve the setup. I also bent some 1/2" conduit to give a little extra support to the tail. I need to find a more elegant way to attach the bottom the the rear triangle, but it's solid as is.

Renamed it "The 'Loper" as "Stretch" has been spoken for.

Great style points for Kingfish, nice work!

Here is my contribution, taken pretty much what everyone else has done and duplicated. I did find one very nice little bit that i haven't seen anyone else use though. The salsa seatpost clamp with rack brackets. I filed the shoulder off so that it can slide all the way down the seat tube, then used it to support the extended rear triangle. I think this looks a little nicer and is also mega strong. It isn't the most thrifty way though.

Also, i welded a couple large (and heavy) spacers onto the bottom bracket ends so that the spacers just thread into the bottom bracket shell. Very stiff this way.

The clamp (link):

Next steps are to do some paint/stain on that wood deck and then sew up some bags sort of like xtracycle or kona ute bags. My wife doesn't really use the sewing machine, i guess i'll give it a shot!

My bike: more pics in the Gallery







Also, this bike will receive a 36v 14AH pack and a nine continent front hub motor whenever the parts arrive. Just added a kit to my wife's xtracycle equipped cruiser and that is a sweeeet bike now!

Extended my Phillips 20 tourer on the weekend... but only by an inch and a half.





Does give me some ideas about acquiring another 20 and doing a full on extrabike conversion as this would address the parking issues one has with a full size extrabike.

Believe I would use custom stays and build up a custom rear rack and deck rather than use salvaged bits.

Thanks Troy. I love your longtail cruiser. You should really post that over on www.ratrodbikes.com. They would love it. If you don't I might post a photo or two.

The end result of my BEER RUN build off bike changed a bit when I decided to go for a fun muscle bike look. Here is the final bike with flashing Cold Beer sign and all. Over 80 beer parts are on this bike. I finished 28th out of the 106 bikes that were complete (200+ bikes started).





And this is my latest build. It is going to be a folding sand bike. Kind of like a folding Surly Pugsley. I call it Fugsley.
I am marrying 20x4 inch wheels from a OCC StingRay to an old Dahon folder.

here's my try at it. i call it "clutch cargo", 'cause it's pretty sketchy (someone also pointed out to me that younger people won't get that)





there's a little more on the freakbike nation forum. usually if i'm on the bike forums i'm more likely to be in alt bikes, but since it fits here and i'm lurking for info anyway, here i am.

just got up this point today for a test ride. need to finish the main mechanics and working out ideas for bags or something. i have one kinda odd idea but it's kind of heavy so i'm working on another. also trying to figure out a center stand.

also since ideas seem to come to me in clusters (i have project a.d.d.), this is the first of two cargo ideas. i'm gathering parts and trying to work out the idea for madsen type bike, but just with a regular rubbermaid type tub. maybe pics of that one in the near future if i get it worked out.

More cool bikes. The beer bike is great! On that last cargo bike, i like the way you've got the suspension still in there and the cargo will be (in theory) given some isolation from bumps! I say "in theory" because i suspect you'll have to get a much heavier spring to offset the new leverage of your body weight on the shock plus the weight of the cargo. Lots of potential there though. I've noticed on both my wife's xtracycle and my home-made one that the cargo can take a pretty good whack from time to time on sharp bumps. Suspension would be nice!

Since my last post i've electrified my bike and made a cargo bag. The bag was a lot of work! From conceptualization to design to physical product took several weeks of working a handful of hours per week. For that matter, it's not totally finished yet, but it's functional. I'm kind of dragging my feet on getting to the second bag, lol! After all this work, the $500 for the whole xtracycle kit and bags and all seems pretty reasonable! lol

I based my bag very closely on the xtracycle bags, but simpler in many respects (easier for me to make) and with a lid-flap which is something i think the freeloaders are sorely missing. I've used the bag several times now and it works great so far. I absolutely love the electric assist on both of our cargo bikes. We ride the bikes everywhere now and have a blast doing it!









Are those pictures visible? Should be 4 of them.

that bag looks good. that's what i need to figure out next for mine, along with a stand. a couple days into fooling with it i dug these out of the garage and worked them into the project





boxes that go along the side of a truck bed. the size and shape are good, and they also lock, but they're kind of heavy (14lbs apiece) and they weren't really made to hang and support their own weight, let alone what could go in them. i'm playing with them anyway as an option while i figure on other possiblities.

right now i'm thinking maybe a canvas bag of a similar shape (probaly more the shape of the rack framework), with an emt frame inside the bag to keep the shape either fully or partially. when i get to work i'll be weighting emt and trying to get an idea of what the weight of something like that will come out to.

are there any more side bag ideas out there? i'm already seeing my second bike as being potentially more "able", unless i can find or make some good side bags for the first one. i'm looking at various military and tool bags, but i can't nail down a good size.

i think i'll be trying the folding conference table leg idea for stands. thought i had a chance to pick up some today from a local flea market, but it's raining.

i've been looking at garment bags, but i haven't seen one that i wanted. right now i'm thinking of a couple of military bags, a-3 flight bags. they'd need to be cut down a bit i think (they're about 24" tall and i'd want them to be about 18") and maybe some reinforcement in a few places, but i think they could work.

if the weather's nice saturday i mean to ride down toward ft knox and look in some of the pawn shops around there to see how much i can get them for, or some other bag that might work better but i'm not familiar with.
