Introduction: A Sociable Bicycle

About: I Love Making Stuff !!

My wife loves riding a tandem but was fed up talking to my backside. So along with a great friend of mine we decided to surprise her and make us a side by side sociable bicycle.

A few beer mats and a couple of scribbles we had a plan and set about the challenge.

Step 1: Finding Materials

We Needed two ladies bike frames which needed to be exactly the same size.

We took them apart and cut off the rear ends.

Step 2: Need to House the Axel

With the rear ends removed from the frame we made a new rear section for the frames with a bearing housing at the end which the axle will later settle into.

Step 3: Making the Rear Axle

A solid 20mm bar was used with a thread cut into each end to house both the freewheels. Also the hub for the rear wheel was made on the lathe. Two separate units with spoke holes. These were slid onto the axel and braised into position.

Step 4: Making It Square!

The next difficult task was to make sure the bike tracked straight and square. Using another head stock from another bike frame we made the centre front section. It needs to be strong as its taking two peoples weight. Measure and measure again making sure everything is aligned. Braise it all together and you should have your frame! Test to make sure you have space for two people.

Step 5: Making It Wheely Good !

Next the rear wheel was built onto the axle and a bracket was added for the gears. Also a loose bracket was made to support a mudguard for the rear wheel.

Step 6: Steering !

The front forks were put in place along with the three headsets and were connected using a short track rod ends from a car. Brackets were made to bolt these together.

Step 7: Stand Back and Look

We loosely fitted all the components to the bike to see how it all worked. We were very please with the result. Quick spray of undercoat to give it rust protection before the test ride !

Step 8: The Test Ride

We had a good test ride of the bike to make sure everything worked as it should and didn't fail.

Step 9: Paint Job

We took the bike apart again and prepared the bike for spraying. Using the green house in the sun, it made a lovery paint oven and we got and exceptional paint finish.

Step 10: Time to Play!

After all time spent on the project it was time to go and play. It's a fantastic ride as you can talk and ride at the same time.

Step 11: Overview

This build is not for the faint hearted but it was enjoyable to be a part of a fantastic project. If you decide to build one please show me your creations.

    you go straight ahead, of course!

    telephone pole will have a nice couple of dents in it, thats all.

    they cancel each other out and disappear

    Well, to quote a wise man, "happy wife = happy life" lol

    A wiser man once said "single man = happier life"

    I rode one years ago, we got it for a blind kid who wanted to ride a bike, they are great fun. The one I rode was set up a little differently to yours, it was made from three bike frames, and the center bike was joined by the pedals to the to outside bikes. Kind of hard to explain but they had made two pedals which screwed into the bike cranks at both ends. So it only had one chain. Also it could only be steered from one side. I tried riding it without a passenger, and found you could do it but I had to ride in circles.

    imagine if one side came off......

    Very nice build. I imagine you would have some trouble if there was any significant weight difference between the two riders. That could always be overcome by making it a tricycle and having two wheels in the back. Side note, I was looking to find a tricycle style side by side tandem that I had growing up when I stumbled on this page, 1910 side-by side, which shows a very similar style bike to yours but was first made around 1910.

    This is the style of side by side tandem I grew up on, just a different color.

    That's neat, a recumbent side-by-side :-) Also no arguing over which way to go!

    Each wheel had coaster brakes so you could really fly around corners, inside person would slam on the brakes. Granted you didn't tip over. But that's what made it fun.

    interesting structure :D
