    Well... I have decided that I need a new extrabike and will be selling my old one to fund the new build as I am going to start from scratch with a ground up design and will need things like frame tubes, fittings, etc.

    I could strip my extra bike down and use the parts but it is a great bike and sure someone will appreciate it as it is.

    Will be drawing a lot of ideas from my bike and the bikes I have seen here... I really like the drop down racks dave used so will have to look at doing that.

    Will essentially be building a tandemesque frame with no second drive or stoker seating but some massive cargo carrying capacity.

    Elias, congrats on your "bike bus" - looks great - love the pink child seat!

    Sixty fiver, I'm sure you can weld up something MUCH prettier! Be sure to share!

    The only thing that is missing is a pair of ape hangers mounted to the front seat.

    You should remove the front seatpost and get some extra long ape hanger handlebars and drive the bike from the back seat.

    You and I think alike.
    Though at 6'2" and sitting on the rear I can bearly reach the pedals at full extension when pedaling.
    The girls have been riding this all over town during the summer (as many as 3 of them at once) They get quite a few comments.

    Thanks to the inspiration from this thread, I finally got it together and built a trailer. My original plan was to build an Xtend, and ended up here. Luck would have it that I was able to secure a donor today as well. I knocked the project out in a few hours and am happy with the results. I already brought home two loads of tools with ease.

    I decided to go with a trailer as I can store it when not needed, and I don't have to find a place to store an extended bike.
    The donor was a kid's trailer. I had some aluminum corners left over from some road cases I made a while ago. I attached them to a wood frame. I put some aluminum cross members on the underside for extra support. The rear supports are foot rests from an old wheel chair. The front is supported by the handle bar.
    Total cost: $50 for the donor.

    I'm thinking about adding an electric motor to the trailer for assist under load.

    The rear wheel is a 24". I am thinking of using a 20" to lower the center of gravity a bit. Would that be advisable?

    Again, thanks for the inspiration.

    This chap in the UK documented his home made longtail build, and a very nice job he made of it too. Apologies if this has been posted before:

    Took "Stretch" out for a ride to the farmer's market the other day as I felt bad for letting him gather dust... have been using my trailer a good deal as I am more comfortable on my folder which is my designated tow vehicle.

    Have offered it up for sale and had a few people express interest but I am still stuck with my extrabike... think I might hold on to the bike through the winter as it really excels as a bad weather bike.

    Hi all,
    I'm new here, so this is a self introduction...

    Live in a small town in rural South Africa, forever busy fiddling with bikes.
    Currently busy scheming my way towards an xtrabike, this thread has been a great help.
    I'll be posting some pics of the mock-up before I start cutting so that I can be gently steered in the best direction.
    Looking forward to it.

    Advice Please

    OK, this is the general idea...
    [ATTACH]XtraBike 2..jpg[/ATTACH]

    Any comments/suggestions would be welcome.

    My primary concern is the donor bike's top and down tubes. Should I remove them and install one support from the top of the donor bike's seat tube to the back of the other bikes BB shell?

    Or weld the donor bike's down tube to the other bike's seat post?

    I wait in anticipation

    First off, you have to think about the head tube angle. If you connect the two frames so that the chain stay is extended in a straight line, you end up lowering the head angle and increasing the trail (and wheel flop). To maintain the existing steering geometry, you have to connect the rear triangle so that it's chain stay is level with the ground, keeping the original BB height. With that done, I estimate that the second top tube will meet the top of the first seat tube. In that case, you can just cut off the head and down tube and you're finished.

    If you're looking to for laterally stiff connection, you need to make sure the second BB shell is connected to the first BB more directly than some bolts to the first dropouts. The way to do that would be to cut off the first dropouts and weld a 1"x2" section between the two BB shells.

    Those who claim to be making history are usually just repeating it.

    Something like this?

    @purplepeople: Thank you for that.

    Looks like it worked out OK. Surprising what a few hours with a grinder and that old sparking stick machine can achieve.
    Rides well, bars are VERY temporary, they were closest when I reached out for bars!

    No brakes or any other gubbins yet, want to get the basics sorted first.

    Comments? Anybody?

    I have read thru this forum, and have been planning this for about 2 years now. unemployed and ready to go! but, i see 2 ways of connecting the rear. BB and shock mount. i would think teh BB is stronger, but what do you guys think? and do you guys use the whole BB? or a bolt thru it and spacers? and last, the stabilizing rod, is that a top tube from a doner bike? or a solid piece? and last.. is more than one stability bar needed? is there flex with this long kit?


    sorry for all the questions!!!

    Broomhandle: I kept the donor bike's top tube (good solid piece of steel well attached at the seatpost end). Does anyone have any ideas about an additional strut?
    I used a 12mm high Tensile bolt with spacers through the BB. Rock solid.

    The O'l mighty ALL SPARK.

    I added extra spacers to the BB spindle of the donor where it attaches to the rear drops(spreads them out further) to give the chain more clearance.Kept getting chain rub in high gear.

    Nice job Johann!

    Thank you, Michael.

    Progress has become steady (i.e. "slower") as I get to the detail.

    I removed the middle gorilla, it wasn't needed
    The cardboard in the triangles is to help me visualise storage compartments....
    The rear rack is a work in progress
    Brakes AND a bell, things are looking up

    One weakness I have identified (or rather two weaknesses) are my very unfit legs

    Latest pics showing what I'm up to....

    The Black Mamba

    OK, so here she is, most of the construction work finished.

    Matt black with a matt clear final coat.

    I have returned the Shimano SLX Chain tensioner to it's original position, it is needed if you have more than the big ring working up front (the previous one was someone's reject and only had the big ring working)
    New crankset (cheapo), new chain(s), Saddle is Murray Orthoped Competition (South African, custom made), Mary Bars from On One, Ergon grips, Deore brake levers and R40 ($6) friction shifters. Eclectic mix, but it works.

    Next stage is to complete the load area.....

    I have a friend making up frame packs for the first and third triangles (100m and 250mm wide respectively) and probably also some panniers for the back end.

    Plywood deck (sorry not too many skatebords round here), this is deep rural!

    And then to set out across the country, particularly as one of the original motivations for building this bike was it's ability to carry extra water for longer desert trips.

    Thanks to all of you for the advice and support...this intraweb thingymajig is damn useful

    Tandem xtracycle

    I've been meaning to post pictures of the finished build for a while. I've actually decided to break it down and turn it back to a regular tandem since none of my kids want to ride on the seat without pedals. I should consider myself lucky that they all want to stoke.
