WOW ! Looks good.

How about some closeups of the attachment points and such.

=)

Thanks.

Sorry I didn,t get the attachment point of the seatpost /rear triangle very well, but it is welded. This came together in like an hour with pleasant results , but i prefer a little better frame components .

Thanks for bearing with me I,m not to adept to posting pics, but here is a second pic. It is hard to see, but the bottom bracket of donor bike( susp mtn bike) is bolted in the rear dropouts of the main bike. A little persuading was all it need to come together , then the crankarm nuts were tightened up. A little something I picked up from building a recumbent is the rear triangle needs to angle downward about 10-15 degrees so the chain don,t interfere in the "joined "area when in the small gears. Last but not least the pipe was held in place and cut,notched then welded ,although this could have been bolted. IMO I like the top tube to face the seat post it completes the d/f triangulation, like i said just my opinion. Cyclaholic, Fordfasterer and Roughrider504, keep up the great work I really like your guys projects.

Nice job, can I have one more pic showing the welding job to the back of the seat post ?

=)

Here is my latest build. I,m really liking this one, it is lighter and has better brakes . The plan is to strip it and paint it black wrinkle .I will also be adding sides' made out of conduit, and a top deck with an unwanted skateboard.

Can we see multiple close ups of how the thing is mounted to the rear dropouts and the main bikes BB?

Thanks.

You guys are making some really lovely longbikes. :)

graywolf 01-27-08 05:47 PM

I think I want to just stick in a little post to say how much I like you guys' long bikes. It is interesting to see how you have went about it differently from each other. Great work!

I think I have "long bike" envy! ;)

Here it is ready for tear down and paint .I,m workin on either gettin some bags made ,or checking out the local Army surplus. The sides are made out of 1/2in. conduit the top rack is part of a rear rack and some brake tubing added to the front of it.

badmother 02-06-08 03:35 PM

Hello
Just to say I am working on my bike, new pix soon. Last night I made one of the big black "bags" Lots of work but looking good :D

Sianelle 02-13-08 06:47 PM

Love the work you've done on your bike bbwolfy it's all come together really nicely. This is an amazing thread and I'm sure it's just going to keep on growing :)
I've got an old Giant 'Boulder' that I started to convert into a long wheelbase cargo bike before I got myself distracted with something else. Perhaps I should haul it out and blow the dust off it and have another look at it.

This was a first try that I setup a while ago using parts from dumped bikes, but I wasn't entirely happy with it.

Careful welding that conduit. It's galvanized. Welding that stuff can make you pretty sick and mess you up for years to come. People have died from zinc poisoning.

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

Trying again.

Sianelle 02-18-08 04:29 PM

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

Allen 04-05-08 05:19 PM

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

badmother 04-06-08 03:50 PM

Agree! Just found it earlyer today. Wish I could find the bamboo here:D

Sianelle 04-06-08 07:37 PM

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

badmother 04-07-08 04:17 AM

I just posted some thoughts and questions in "fordfasterr"`s thread about his longtail: http://bikeforums.net/showthread.php?t=379537

badmother 04-07-08 04:39 AM

This is my posting: So I am planning to make another one. After alot of thinking I`we decided that at least in theory I like your way of joining the two pieces together (the long threaded rod) better than mine (using the axel of the donor). Terefor I would like to know if it is working ok? Acctually I am asking, Is the threaded rod bending in use?

I think the pix of your bike should be found in the "home built" sticky, becouse it is a sticky. This way it is kind of disappearing as time goes..

Hoping for more pics of homemade longtails, a lot of peopel was making them but then stopped posting. Is the longbike of "diff lock2" on the road yet? Is "Sianelle`s" on the road?

Did you see the Bamboo one? I guess it is light compared to what we are making.

I`we spent some time in the folder bike forum, and has restored a folder. Therefor thinking alot about wheelsize and wheel strenght. What about making a 24" longtail and just use a long seatpost and stem? Smaller wheels is stronger and weight should go down. Lower center of gravity.

Next is, what about a Bmx based longtail? Would be strong, made to take a beating. Short tubing= strong. Small wheels= strong and light, low c.o.g.

IT IS SPRING LONGTAIL BUILDERS, YOU SHOULD WAKE UP!!:D:D

I need one of those rear triangles!

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)

JeanCoutu 05-06-08 05:47 PM

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!
