Picture of Build Your Own Tall Bike Without Welding
IMG_0266c.JPG
This is the easiest way to make a tallbike.
You don't need a welder, you just need whatever tools you have.

It was 1997 or so, and I was noticing that all the cars looked the same, and all the houses looked the same. Then I realized how expensive that was for the people to do it, to go out and buy whatever new car the superbowl halftime ads told them to.
It must take a powerful fear to motivate such extravagance.
The fear of not blending in.

I resolved that at least my bicycle wouldn't be just like every other.
In a blur of frantic grief for the conformists, I started working on my bike.
I recalled something we used to make as kids, "upside down tallbikes".

Note - This instructable is "descriptive documentation" and doesn't show any hands building things, just the things themselves.

Warning - you can fall off one of these and get hurt.
At least one person broke an arm falling off one of my bikes. I felt really bad and didn't let anyone ride my tallbikes for a year or so.

Step 1: Get the Right Kind of Back Wheel, Invert the Fork

Picture of Get the Right Kind of Back Wheel, Invert the Fork
The most important thing in this whole project is to get a back wheel with the right kind of hub.
The kind you want is called "coaster brake" or "bendix hub" or "back brakes" or "standard".
In the U.S. it's the default type of hub on a bike that has no other name.
It's our nation's greatest contribution to the bicycles of planet earth.

By using this type of hub you'll avoid having to mess with shifter cables, derailleurs, etc.
It'll make your tallbike building experience much quicker and more pleasant.

I bought this cruiser bike for $20 from a yard sale on Cape Cod.
I could tell something good was going to happen, so I took these pictures.

As seen here,
I took the fork and handlebars off and put them back on upside down.

Step 2: Upside Down and Backwards

Picture of Upside Down and Backwards
Then I flipped the whole thing over so it looked like this.
I tried to ride it like this, but the pedals and wheel turned the wrong way.

I turned myself around and tried to ride it that way with rearwheel steering and front wheel drive.
A series of spectacular wipeouts ensued. I wasn't able to ride it more than ten feet or so.

Step 3: Turn the Pedals and Chain Ring Around

Picture of Turn the Pedals and Chain Ring Around
I gave up on frontwheel drive and rearwheel steering for the time being.
I took off the front chainwheel and pedals, turned them around, and put them back on backwards.

The chainwheel rubbed on the frame, so I took it off again and beat on the frame with a hammer til there was a divot and the frame didn't rub anymore.

Step 4: Turn the Rear Wheel Around

Picture of Turn the Rear Wheel Around
Then I took the rear wheel off, turned it around, and put it back on so the sprocket is on the same side as the front chainwheel.
There's a lever extending from the side of a bendix hub.
The lever needs to be restrained for the brakes to work properly.
If it just uses a sheetmetal band to attach it to a frame tube, shift that over to the new side.
Sometimes it's attached to a tab on the frame.
If so you can hoseclamp it to the frame in the new position or scavenge the sheetmetal band from a different bike.

Next I had to use a chain breaker tool to take the chain off and put it back on on the new side.
Park Tool and Sheldon Brown are good sources of info on such bicycle tech and craft

Step 5: Wood - the Miracle Material

Picture of Wood - the Miracle Material
Here's the bike as it appears now in 2007, ten years later.
It's been ridden by hundreds if not thousands of people and was my primary transportation for years. I usually ride it with the front wheel turned around as shown here.

Eventually the hoseclamps holding the frame together broke a few times.
Then the two seat support tubes wore grooves in each other and the big one broke. So I got a nice piece of hardwood, I think it's ash or beech and lashed it in place.
Unlike metal, wood doesn't fatigue.

Step 6: Frame Lashings

Picture of Frame Lashings
IMG_0277.JPG
IMG_0274.JPG
Here are the frame lashings I replaced the hose clamps with.
They look fancy but there's no real advantage to doing it this way rather than some other uglier lashing.
Just wrap some string around the parts you want to stay together.

I used nylon string soaked with water. Then when the string dried they got tight.
Nylon elongates more than 10% when wet.
Then I soaked them with epoxy to make them permanent.

Step 7: Tall Seat Tubes - Alternate Lashing Method

Picture of Tall Seat Tubes - Alternate Lashing Method
lash2.jpg
Rebekah Rosenfeld works on her tallbike, advised by Damon Vander Lind at MITERS.

She's lashed her seat supports with synthetic rope and then soaked it with epoxy to make it permanent.

She started with a mountainbike frame, removed the derailleur, and shortened the chain to make it a one-speed. This is a more difficult method than using a bendix hub. She'll have to make some very long brake cables to get them up to her handlebars.

Step 8: Seat Attachment

Picture of Seat Attachment
I got this Huffy seat out of a trash pile. It had nice long brackets.
I bent them close together to line up with my wooden stick.
Then through-bolted it as seen here.
The other method uses a stick across the base of the seat which is bolted to the support stick.
Unfortunately my bikes like that were borrowed and lost so I can't take that picture.

Step 9: Seat Support - Axle End

Picture of Seat Support - Axle End
I poked a bolt through a hole in the rear dropout and drilled a hole in the base of the seat support tube to match. I was planning to pound a wooden plug into the tube to make it stronger but never got around to it. It seems to be okay.

Step 10: Steering Column

Picture of Steering Column
There are lots of ways of doing the front handlebars, this is what I like.
It's not very stiff, some people find that unnerving.

I'd like to take pictures of what's inside the steering column,
Unfortunately the metal bits have all corroded together so I can't easily take them apart anymore.
Instead of the headset there's a stub of steel pipe bolted into my fork tube.
It's cut off at an angle at the bottom so the original angle nut can bind it in place with the original headset bolt.
The aluminum tube seen here is slid over that steel stub and clamped in place with the gooseneck from the original headset.

This particular aluminum tube is thick and springy. It doesn't get bent like stiffer tubes tend to, it just springs back.

Step 11: Wooden Handlebars

Picture of Wooden Handlebars
This is my favorite type of tallbike handlebars. It's a rung from a wooden chair clamped in a mountainbike headset.
Because my steering column is so flexible, wide handlebars don't feel good.
They put too much leverage on the steering column.

Step 12: Testing

Picture of Testing
The first time I rode the bike down the street and it was a blast.

Like riding in an airplane with my problems far away.
Bystanders honked and gave me thumbs-up signs.

I rode the bike to work and my co-workers loved it. Even the wipeouts were fun.

Here Dave Russel finds out that the front wheel doesn't have much weight on it and likes to do wheelies.

(A year later someone broke an arm falling off it, so be careful)

Step 13: Front Cargo Carrier Boards

Picture of Front Cargo Carrier Boards
frontboards1.jpg
A month went by and it was time to do my laundry. 30 shirts and a proportion of other garments made a large bag of laundry. I tied these boards on the front of the bike and draped my laundry bag over the top like saddlebags. It worked really well. Being up in the air left a lot of area low down for cargo.

Step 14: Bike Wagon Made from Elevator Door

1998tallbiketrailer.jpg
My mom's family says "lazy man's load" for a huge load trying to move everything in one trip.
The inherited joke is that laziness often creates more work than it saves.

Anyway, I need to move more stuff than would fit on my bike.
So I scavenged this door from a freight elevator, cut a couple of aluminum signs in half diagonally, bolted some kids bike wheels between them, and made a quick bike trailer.
It was pretty wobbly til I added enough cross sticks and guy wires between the wheels to triangulate it.

As I recall, the trailer hitch is just an eyeoblt with a loop of rope through it.
Or maybe it just goes through a hole in the end of the tailer tongue.
I looped that rope around the frame tube by the rear dropout and pull it tight with a bungy cord or other lashing. It worked pretty well, but later I changed to a higher longer tongue that I innertubed to my seatpost. That let me do tighter turns.

you still have those purple bars?
would you sale them to me?
AronC08164 years ago
I got bored so I drew up a diagram of what he did to attach the handlebar stem. I had thought this same idea up a while ago but never went about doing it.

Thnk U so much ...you clear the concept.
AronC08164 years ago
If you build another one of these I have a recommendation for you. You can take an aluminum crutch apart so you just have the wishbone shaped outer part and use it as the seat support. Just invert it and bolt the "Y" shaped opening on both sides of the hub. This way the support is much stronger. Also if your a bit OCD like myself it makes the bike symmetrical.
AronC08164 years ago
Just wanted to let you know I love this build! The only thing that worries me is using the coaster brake rear hub. I feel like if your up that high they it may be dangerous because these hubs have a tendency to skid, causing the rider to have to suddenly jump off. But if it works then more power to you!

 i am doing this project . and i am stuck on this spot have any tips for a young builder

But welding is half the fun! lol, very interesting concept... i want to rake out my tall bike.

Let's take a video tomorrow of how to mount and dismount a tall bike!
Dismounting is easy, painless no. XD
how do you get onto a tall bike?
i was wondering that too...
add this to my group!

Wow, that is great. But it is too much risky. I will not apply it.

sorry, but this step has me bewildered; what do you do here? jam the big pipe into the steerer tube and then what? I don't understand how it tightens. and once I understand that, I'm making two of these; my friend and I bent our old frames, so flipped upside-down, they should work fine as great tallbike cruisers! props on this, but I'd love to know how to fasten it.
TimAnderson (author)  Nkevin907 years ago
The original method seen here clamped the tube over the stub of the headset. A simpler way is to jam the handlebar column pipe in the steerer tube, poke it out the bottom, drill a cross-hole and put a bolt in it.
I don't quite understand what you did for the handlebars. Did you chop a stem in two and insert both ends into steel tubing? I love the idea and am eager to make one to ride in the HOBT Mayday parade. -Ari
I built one just like this back in the summer of 1976. I even have the pics to prove it. Great to see someone else came up with the same idea! - Thank you.
TimAnderson (author)  kamikaze_Co-Pilot7 years ago
Post the pictures! Any idea when the first one was made?
I have to look for the pics but I know I have them. When it was made? I only know of myself and you who came up with this idea. I put together mine wirh my dad's help in 1976. I had my dad spot weld it together and I used a car steering wheel in place of handlebars. Later I had painted it red and silver. I no longer have the original bike. Some jealous neighborhood kids destroyed it. I'll never forget how cruel they were to me and the bike.

Great Instructable, just finished mine last weekend. However for the steering column I used 1/2 steel pipe with a T joint at the top and some 1ft pieces for handle bars. I also bolted the pipe to the top of the fork for steering and it works great.
Hilarious. Hats off to you bro. This is the answer to high gas price and pollution.

popular mechanics ran an article around 20 or 30 years ago on building a tall bike out of bike parts and hose clamps basically. this is like that.
That last picture looks like a bicycle version of a moving van. Nice work on the trailer too.
These are great, you can see forever and you don't get run off the road by cars passing you 2 inches away. I taught my dog to ride on my shoulders, like a shawl, with her front legs on the left and her rear legs on the right shoulder. She loved it. This is plenty tall enough to be fun to ride, but short enough as to not get you arrested driving it on the road. Your mileage may vary.

i gotta hand it to you man, that is a sick bike for not having any welds.
How exactly did you take off the pedals and chainwheel. I've gotten this far and kinda gotten stuck. Great idea though, can't wait until its finished!
There are kinds of crankset that are easier to take off and reverse, and kinds that are harder..
Dude that is one cool ride, I love finding projects that don't require welding because I don't have a welder and it's by far less complicated + I never would of thougth to turn the bike upside down great idea! I have to make myself one with my tiny clown bike!
Clown bike??!!! LOL
I added long forks to my bike and experienced the "wheelie" effect; so I dumped some BB's down the forks (after capping the bottoms, of course ;-) and it helped to counter weigh the front. No more wheelies!

Great...-...
thankyou! i love it when i can build stuff without a welder! until i get loads of money or go to the right yardsale and get one this will work great!
Gorgeous project ! But I d definitely do some welding just in case ! And by the way, TIM ANDERSEN IS GOD !!!!!!! bravo !

Wow, that's too easy not to do.
