DIY longtail -could it be this easy?

[colby]

can't believe i haven't seen this thread earlier!

I was working on something like this late last year.

i got a little sidetracked with some other projects and never finished

funny thing is i've been thinking about how i want to finish this bike.

what i still need to do is cut the rear top tube off and add a shock in its place.

Colby, nice build! lots of room for batteries, cargo-racks, and perhaps making a non-hub drive using a Bafang/Fusin?

Earlier in this thread there's a long-bike link from Vanilla-Ice, I followed that link to another link...

A 20" longtail...looks professionally welded, but may provide some ideas...

I really like the lines of the Bamboo Mixte style. I can feel the pondering beginning....

hey spinningmagnets,

i checked out your longtail thread and it looks great!! good job!

once you find your comfort spot you can frame in that seat area and it will be solid

hey amberwolf,

couldn't agree with you more. great lines

Another one from the cargo-bike thread Vanilla-Ice suggested. Two common trash-day bike racks and an old skateboard...notice the old derailleur as an idler halfway along the chain. 17 pages of longtail examples (no two exactly alike, many great ideas):

I did that derailer as a tensioner thing. Worked a lot better than the rigid idlers because of the spring.

damn, I love this thread..so much info and inspiring builds.

Big up to Vanilla Ice for bringing up bikeforums.net builds. http://www.bikeforums.net/forumdisplay.php?f=261 , and to Tyler for adding my bike to this thread. And big up to our very own Justin Le for being so laid back on his bike, because that's what ebiking is all about for me, laying back and letting electricity do all the work

Yeah great thread. I knew damn well that when I "invented" the idea of dropping the bb shaft into the dropouts, I'd seen it here somewhere....

I may still hold the title for the simplest construction though. blew my mind when I could sit on the bike before I welded anything. Loving my bike, which now sports a ping battery in the front triangle, and some motorcycle saddlebags.

Hi dogman!

I know what you mean by subconsciously being inspired by things you've been seen before..I get disappointed sometimes because I always strive for originality, whether I'm "first" or not.. But you know, such is life/culture… it's natural to "grow" or "branch off" or "improve" on other people's ideas.

The people who catches original ideas out of the sky are the true geniuses...

Most of the time, I "invent" a variation of what's already been done… like this:

Rear axle in the drop-outs (not BB) and I used a hacked off part of the main frame's pivot, notice the upside down decal? I also used the rear hub's outer-race nut to center/support the hacked frame. I'm sure I'd not seen this method before. I hope other DIY peeps will find these ideas useful.

Also, notice the other hole I drilled? that was mistake DOH! I was worried that the holes would cause the frame to taco but it has held up really well with all the load it has been bearing!!

The thing that I'm wary of are people who do not care about striving for originality or even improvement..people who blatantly plagiarize/harvest ideas from the net just to put money in their pockets. *cough(%&(%(pi)0'&)%2"

[dogman]

After 5 years as a professional folk artist/craftsman, I lost all inhibitions about blatantly copying other artists stuff. Made $3000 a year then too! In the art world, there is a saying, that everything original starts out as copying something. It's the tweak you add yourself that matters. Of course, if you don't sell your art, then you can be as original as you like.

I do hope people copy my longtail. It was soooo easy. Though I used a bike with a steel frame for the rear section, and welded it, I see now that the way mine was put together it could be alloy. You'd weld the bb shaft to the steel front frame, then use some kind of bolt through such as your pic to support the connection at the seatpost.
