found these on ebay this morning

http://www.ebay.com/itm/150665107150...84.m1439.l2649

just like the a-3 bags i was remembering, but only 15" tall, so i wouldn't have to cut them down and worry about how well i could resew them or how much it would be to have it done. truthfully i'm thinking they're like a copy of the real military bags.

but i went down towards ft knox anyway just to be sure. all i found were bags like i remembered, 24" tall and also twice the price. the shipping will be more than made up compared to trying to alter the taller more expensive ones, so i brought them when i got back home.

i'm going to want some more of the webbing along a section where i plan to attatch them to the bike, just to be sure. hopefully the cost won't be too much (a seamstress i go to who's been able to sew up the weird things i show up with). some of these bags are waterproof. since they didn't say so i'm guessing they're not. maybe i could scotchguard them or either cover them with a plastic bag or line them with one.

anyway, they're part of the project now. hopefully they have the potential to be decent bags for the purpose.

How is this for a longtail for you?
Wait til I add the water ski deck to the back!

I finally have a rolling chassis for Fugsley (folding Pugsley) - Harley tires on a Dahon folder.

Long distance touring

I am considering the design with the rear end of the suspension bike. Just curious, has anyone done any long distance touring with this setup? can this really hold 200 lbs.?

Thank Mountaindave.

By the time i finished that bag (and now, as i contemplate making another one for the other side) i've come to the realization that the commercially available bags represent a pretty good value! I haven't come across any other kinds of bags that seem like they'll work as well for handling the variety of cargo that the purpose-built bike bags will carry. You can put anything from a cooler or very large box, several grocery bags, etc into the xtracycle style bags. They are not a bad buy. Also, the Yuba Mundo bags are available for sale on their own and look to be very nicely made. I like that they have a top. Keeping things out of sight goes a long way toward keeping them from being stolen or messed with when you're away from your bike! Also keeps rain off.

It's hard to compete with stuff made in China or other places with under-paid labor. You can't hardly buy the material for the total coat of the above eBay item. I was going to make some hockey bags when I found new ones for LESS than the cost of all the materials. I don't mind making things for myself as a hobby, it's usually better and fits precisely my own needs, but sometimes my time costs way more than I can give to a project. It's a fine balance.

I am taking the plunge. I think I just figured out, though. how to make a rear suspension system . I just chopped a K-2 SideWinder Mountain bike, alloy frame but wicked sturdy, heavy aluminum. Pics pending, just curious is anyone else has pics of a rear spring setup (as opposed to the standard design here) , and how it rides. I'll probably just crank the spring down relatively tight. I also figured out how to make two cross braces instead of one, hmmm.

When I was building up my extra bike I pondered using the rear suspension as all I would needed to do was not use the steel brace and add an extension to the old shock absorber mount.

The ride on the extra bike is so smooth that a suspension is not required and it would have messed with the rack system and defeated the primary purpose of building the bike.

it's untested but i have one on the page before. i've only sat on the rearmost part of the rack to see what would happen (about 210lbs dressed). it sagged pretty good but didn't bottom on the cross brace i put near the wheel. i'm feeling pretty good about it 'cause it's a light spring. when i switch it out to a spring from an adult bike it ought to do ok.

Sixty fiver,

I thought about that as well. I'm not going to have the shock be real loose. If it doesn't work I'll just get another rear end. This one comes with a decent disk brake which I have never tried. I also figured I could use a seatpost mounted rack with a sturdy steel girder for the front of the rack and then mount a BlackBurn to that. If the rack needs to flex a little, it can because of the spring steel mounts. So it will have a bit of a hinge in the mid section. Yeah I hear you though I don't want to hear creaks and squeaks, but so far this looks okay, everything lines up perfectly.

Donor triangle attachment

A couple of basic questions - I think i know the answers but want to be sure.

1) The attachment point of the donor rear triangle in the rear dropouts of the bike to be extended:

Am I right in thinking that you can do this by leaving the bottom bracket in the donor rear triangle, and swapping the crank arm attachment bolts for (much) longer ones of the same thread, and filling the excess space between dropout and triangle with washers? Or is there a better way? Maybe just using one long bolt, removing the BB on the donor triangle... but then what do you use to centre the long bolt in the donor triangle BB shell?

2) My proposed bike to be extended does not have a kickstand bridge between the chainstays, but a small bridge for mudguard attachment with the hole going front to back. Would this be robust enough for the bracing strut to be attached. Would I have to use a slight smaller diameter strut with maybe a thicker gauge?

Thanks in advance and apologies if the questions are completely idiotic.

Barchettaman, that's exactly what I did with my home built. Use the BB spindle from the donor, some bolts and I used spacers instead of washers, but I'm sure the washers would work too.

I also did not have a kickstand bracket on the main frame so I used a handrail fitting that I found in an industrial catalog, like McMaster Carr, and I attached it to the seat post tube and used an aluminum pipe to attach to the donor shock mount. See the pictures. These were taken a while ago, didn't have the rear brakes hooked up at this point. I've since added the brakes and an electric front hub motor kit. The bike has been a ton of fun.

Whew...

Got to re-read this thread for the bazillionth time a I went through it and restored images that were lost in the crash... could not get them all restored but got most of the good ones.

Stretch and I are going to go and teach a class on winter cycling today... the sun is shining and as he is not wearing studded tyres (yet) it will be nicer than taking the new ice bike and I have a lot of stuff to bring with me.

With all the ingenuity on this forum, I'm still waiting for someone to come up with a good long-tail attachment that will fit seamlessly on an Adam's trail-a-bike. Imagine a bike that would be a regular bike when you want it and easily convert to a long-tail when needed. With all the trail-a-bikes out there, I'm sure there's a market for this...

We offer an expedition tandem that converts to a trail a bike, a single longtail tourer, and a triplet... cost is a mere $15,000 Cdn



A few shots from this afternoon... winter cycling class went well and it felt like winter on the ride home so it was nice I had packed extra gear as it was nice enough to ride in shorts this afternoon.

Rocking some 2.1 Kenda Komodo tyres and am quite impressed at how well they roll out on the street and am looking forward to seeing how they roll out in the snow.

69tr6r, that´s exactly the solution I was looking for. Back to the hardware shop for a ´Clamp-on Tee´ handrail fitting!
At some point I will be looking for an electric assist on the front wheel too but we´ll see first if Mrs Barchetta is happy to ride it without one.
Thanks all for their contributions on this thread, it´s a cracking read and has inspired me to get cracking with our Frankfurter XtraFahrrad!

again, a non serious thing for me, but i've thought about adding a trail a bike to this



i don't have a kid to worry about it though, so it's even less serious than the rest of the project

a tandem cruiser idea i've been fighting with. i'm using a 20" fork for a luggage rack an left part of the steerer tube on it. i'm thinking i can modify a few old goose necks and use them for attatchments. like one with a skewer for towing bikes, a one wheel trailer i'm thinking about (from a kick scooter), or a trail a bike. truthfully, i wasn't thinking about the trail a bike as a long tail extension, but...

Hi,

I'm looking to build a cargo bike based on the examples here. But I was wondering, where the rear swing-arm attaches to the rear drop-outs of the main donor frame, is it best to use a frame where the dropouts are horizontal - or would a more modern vertical dropout suffice? I'm worried that vertical dropouts would allow the joint to fall out under load?

This sort of drop-out:

Not that frame in particular- obviously

Vertical dropouts will be fine.

I'd like to express my gratitude to each and every person who contributed to this thread. The building of my first cargo bike would have been a lot more difficult without you!

I'd like to express my gratitude, too,
to Ross Evans and all those who developed the xtracycle concept in the first place. A simple idea that makes a big difference.

After I built a second and better one, I to ad a link to this chain.

It took quite a while, but it's done.

I've put a tutorial online on how to build a long tail cargo bike, including pictures on every detail I could think of. Text is Portuguese (my mother tongue) beacause it is aimed to Brazilians and other Portuguese speaking people (in Europe and in Africa). Spanish speakers will be able to understand almost every thing without a sweat.

all the best

I haven't posted an update of Fugsley in a long time.
Dahon folding bike with Harley Davidson tires and OCC STingray frame parts and a water ski rack thrown in.
You can see the entire build diary on Rat Rod Bikes here
http://www.ratrodbikes.com/forum/vie...p?f=21&t=44315

Here is the frame with no tires.


And with tires

Sweet.
I made one this week end, $35 for the two bikes. I still need to connect the gear/brake cable and put on a second rack.

The rear screw holes for the rack to connect are larger than the rack holes I have. Are these standard, or do they come in different sizes? It is the back from a big box store full suspension bike.
