    Tall Bikes

    "There's some seriously scientific shit going on that blows every other vehicle out of the water."

    https://www.redbull.com/us-en/tall-b...rld&cmpid=RBFB

    I used to see the hipsters riding these around Cambridge and Boston when I lived in the city. Usually at night in large packs with all kinds of lights and other accessories.

    Anyone ever ridden one? Built one?

    Not gonna lie, It seems like a fun project. Too bad I have absolutely no welding equipment, knowledge or skill.

    Maybe I need to get DoWork on the job...

    Ridden quite a few. Fallen off several. Never sober on either.

    Google 'CHUNK 666 portland' and plan your road trip. You will find your people.

    Tall bikes are definitely fun, and so are swing bikes. They all seem to be one off garage builds. I've ridden both around Carbondale when a bunch show up for full moon bike rides, but its been a few years. What I really want to see is a tall swing bike! That would be wicked.

    I have a tall bike I built with no welding.

    The top frame attaches to the bottom frame at 3 points:
    top forks have an "axle" made of allthread and 3/4" diameter washers that clamps to the stem of the bottom frame. The head tubes of the top and bottom match angles and the offset of the top fork matches the length of the bottom stem so they turn with no resistance.

    The bottom frame has a seatpost that comes up and bolts to a kickstand clamp on the top frame.

    The rear triangle of the top frame has another false "axle" made of allthread, and there are aluminum struts connecting the top rear dropouts to the bottom rear dropouts.

    I have front and rear brakes set up with tandem cables (for length).

    Drivetrain is 1X7....I have square taper bottom brackets in both frames. Top has the crank on the left side and drives bottom through a primary chain tensioned by a modified derailleur bolted to a bracket that bolts to the water bottle housing of the bottom frame. Bottom frame bottom bracket has two equal toothcount drive side cranks with the crank arms cut off, left side is driven from the top primary chain, then the right side drives the rear wheel as normal. I have a friction thumby running a tandem cable to the rear derailleur.

    On the rear aluminum struts, which are super strong and cross braced with grade 8 hardware, I built steps on both sides to step up to the pedals.

    I love my bike, it rides really shockingly well and people trip out when they see it.

    So, no welding, it can be done...just takes careful planning and execution.

    this is an old photo before the drivetrain was finalized. This is when I was just running chain direct from the top BB to the rear wheel. It was OK like that, but had interference issues with the top frame chainstay and bottom frame brakes so I couldn't access the whole cassette worth of gears, and to clear the brakes I had to run a ginormous (52? maybe 54 tooth chainwheel that made climbing brutal).
    That's why I developed the other more complicated drivetrain. I'll go snap some shots later and put them in this thread.

    I know fuckall about tall bikes but that's neat to hear how you did it. Never really thought about a lot of those aspects.

    Would you ever think about a Tall EBike?
    If you want me to take a dump in a box and mark it tubeless, I will. I got spare time.

    Pennyfarhthings?

    I was at an event a few years ago where they had a pennyfarthing race, and one rider wound up in the hospital (duh). Greg Lemond was there and I got a few pics of him riding one. I'll see if I can find them. There was a guy who rode one across America, which is quite a feat, considering the downhills in the Rockies. You just put your feet up on the bars and pray.

    Someone who I assume lives close to me because I see him a lot in the hood has one that's remarkably similar to yours: no welds, front fork attaches to a spindle with a roller shim through the original stem, aluminum angle bar between the rear axles... it's even yellow! The only real difference is that he has the upper chain go to one of the lower crank's chainrings, and the other is the original drive chain to the cassette.

    They seem to be all the rage lately. Seen 3 different ones in Burlington the last couple of weeks.

    Thanks for sharing Ill Advised.. sorry I missed it earlier.

    Inspirational for sure with the no weld setup, i have 2 old raleigh frames in the garage that may have this in their future.


    Please share pics of the drivetrain and top to bottom frame attachments at the stem, seat post and rear dropouts if you get a chance!

    sturdy, very rideable, no welding!

    When I was little and my mom was in college, she was down to her last money and her car broke down. Instead of fixing the car, she said fuck it and got a Ross mtb, which was one of the first mtbs in town at the time, and rode everywhere all year for years. She was going to give that bike away and I was like NOOOOO!!!! so I saved it and tried to make it into a rider for my wife, but it was just too big for her, so it sat until I found just the right bottom frame and made that sentimental frame the top of this kickass tall bike. My elderly mom is stoked her sentimental mtb is this working piece of art that's so fun and people love so much. Riding this bike is one of the best parts of summer.

    Awesome, thanks for sharing. My project will start next week, I'll update this thread as it progresses!

    Edit** Please chime back in with any specifics you can about the rear strut work. Connections, bracing, and what looks like an on/off step.. TY Sir!
