my next build

[roadmaster]

winters boredom has sunk in and the creative insanity or just insanity has set in. i have an extra frame (huffy diamond, nothing special) that was a mountainbike that i converted to single speed. now i need a bike that i can use to roll on down to the grocerystore and laundry mat, and i am finna to not only put on a rear rack and a front one as well, but am going to build a boxbed out of wood to attatch permanetly to the rack and add supports to attatch it to the bike. i havent handbuilt a boxbed onto a bike since i was 7 and my dad built one for the back of my "big wheel" bike.

now the box itself has gotta be big enough for at least my tools and s few bags of groceries. my first specs put it at 15"wide x 10" deep... now i could be safe and just go a length of like 20", OR throw caution to the wind and go like 40" long and add a 3rd 24" wheel behind the rear wheel for support. how wild would that be? has anyone attempted to made a 3 inlined wheeled tricycle. with the industrial gearing on it, its NOT built for speed, but i thought i could throw a 24" wheel onto an extra fork laying around and then just mate up the rear 3rd fork at the rear of the extra long box on back behind the drive wheel. :shock:

should i play it safe OR should i build this 3 wheeled bike truck frankenbike? now if i could actually rig up steering to the rear 3rd wheel itself...

I think a three wheel inliner would be kinda tricky to steer and navigate uneven terrain...Sounds like a cool idea tho IF you could make it work.

OK,now ya got ME thinking about it...

How about 2 frames,back to back sharing a common center wheel with a suspention fork at each end to steer...The rear fork would have to steer opposit of the front.

If those trail a bikes follow the bike without a steering system, why wouldn't an inline third wheel rack? You would have to have a pivot somewhere so it would follow along but I'd think it would work. Take a look at those trail a bike things that attach to the seat post and let the kid ride along sort of like a tandem. That should work eh?

Can you stretch the frame and do something like the Big Dummy?

i accept i will not be able to ride on uneven surfaces, unless i could figure out a suspension system for the rear wheel and add a front suspension fork. that way, each end would be able to soak up minor to moderate uneven riding surfaces. perhaps going down to a 20" rear wheel in back would help.

i also thought about the trailer with seatpost pivot point idea, and I DO remember those towbehind "half a bike with a kid on it pedeling" things from back in the day. i am limited to primarily wood as my building materials as i have no access to welders, and knowing how to weld only makes it more frusterating. . the box part of the trailer is a no brainer, id have to design a sturdy yet functional "arm" to go from box to connection at the bikes seat post. OR... i convert the bikes rear rack with a homeade "5th wheel" style hitch :mrgreen: :mrgreen: . wouldn't be that hard if you think about it and useing the rear rack to put on and support a semi truck's tractor "5th wheel" set up to your trailer. a better connection than a seatpost and more leadway for coming up with "ratty innovations" and customizationing.

better yet, i can do this trailer thing in the beloved style of the old "teardrop" style trailers. single or dual wheels could work on this, but i bet with an old fork mounted on the back of my box bed or "teardrop" idea, and a single wheel, i could pull this off. anyone up for a rat style "teardrop trailer" build off? :mrgreen:
