Two Go

By cutting a plastic crate and using seven standard joint parts,
you can create your own dual-purpose cargo / extra bike seat*.
Doing so enables you the possibility to transport easily and environmental friendly,
while enjoying a mutual riding experience.

Here are the instructions  Now Do It Yourself!

How much weight does this hold?

[gromo]

Nice :)

[Mr.Sanchez]

Nice rulebreaker bike.....!!! Hooray for freedom...Sometimes to get my kiddo to his school on time i have to carry him on that way...Just be carefull.
In my country (Colombia), is Legal that kind of Locomotion.

[RionNipal]

I don't know about where you are, but in Toronto this would be illegal. You're not allowed to ride 2 people on a bicycle unless it's an infant in a carriage behind you. Also, carrying 2 people like that is very rough on the axles and tubes. if you double ride people too often, you'll probably pop a tire, warp a rim, or bend an axle.

THIS IS THE COOLEST THING EVER!!! I have always wanted to make this exact thing but I could never figure out how to do it!! Thanks so much!!!

[FeedTheGrid]

Great idea. Well done. The drawings are pretty amazing, too. : - ) FTG

[yaeliv]

:-)

[Kactapuss]

Really well done!

[coastrider]

NO DONT CARRY A PERSON OR CHILD ON THAT YOU ARE BETTER REMOVING IT ALTOGETHER & GETTING A TAG A LONG IT SECURES TO THE SEAT POST < EASY REMOVED > UNIT ITS A ONE WHEEL BIKE WITH HANDLES FOR A LITTLE PERSON WHO CAN HELP PUSH OR FOR CARGO YOU REMOVE CHAIN TO REDUCE WEIGHT PEDDALS.. & INSTALL A BAR FROM THE HANDLE BAR NECK TO THE SEAT POST CREATING AREA TO SECURE A SET OF SADDLE BAGS STRONG BAGS .. OR GET A KID TRAILER BUT MAKE THE BASE OF IT A LOT MORE STABLE AS IT RIDES CLOSE TO GROUND ... IM TESTING A SET OF BIGGER WHEELS FOR BETTER GROUND CLEARANCE

[Kactapuss]

WHY DID YOU TYPE IN ALL CAPS?

[satchelhayes]

i like this alot
and the fact that you can have the second passenger pedal makes it more appealing
what did you use underneath?

[yaeliv]

 I'm not sure i understend the question...
There is no pedals for the second passanger

[satchelhayes]

you made the seat and cushion but what did you use to hold that up and support the 2nd passenger
right i understand there arent two sets of pedals but isnt it possible to have the 2nd passenger pedal from the back seat while the front rider puts his/her feet up?

[yaeliv]

 It can be possible... you will have to build it yourself and try   ;-)

[hyperactiveguy]

This is pretty cool! I was looking for a way to puta passenger seat on my bike, but never saw anything where anyone actually did it. Very nice, but you could also just remove the rear rack and get a big banana seat. Anyways, very good!

[Kroensburg]

Does the average rear wheel rack support the weight of a person? Or do you have to be pretty careful about selecting the right one?

[yaeliv]

that's a good question. the average rear can support it, but it recommended to use stronger one that made a specially for heavy wights, so you wont be limited

[Gorfram]

A word of caution: Please clearly state somewhere that this seat is intended only for adult passengers. Any seat for children needs a guard to keep their legs and feet away from the rear bicycle wheel. When I was five years old, I was riding in a homemade bicycle passenger seat not nearly so nifty as this one, but also without any sort of wheel guard. My foot got caught in the spokes and my anklebone was shattered against the bicycle frame - the pain was absolutely incredible. I was in a cast for 3 months, and 40 years later there are still leftover bone chips in my heel that ache whenever my feet get tired. Please don't risk this.

[CorpseRsCarla]

definitely a good idea to note that it's for adults. Things like this are illegal for children here in New York. Our state laws are really strict about child restraints and such. awesome idea though.

[yaeliv]

thanks... :)

[yaeliv]

thank you very much for your comment, I added this warning... it's really important.

[Gorfram]

Thanks for adding the warning, and thanks to CorpseRsCarla for seconding my comment. I'm glad, too, that I don't seem to have come off sounding too much like I was taking Yaeliv to task over something my father did more than four decades ago. Most places in the US probably have now some sort of general or specific regulation against transporting children this way. My accident happened in 1967, which was a very long time ago by safety standards: no one I knew had ever heard of bicycle helmets or automoitiuve child safety seats, and seat belts (lap only, no shoulder belts anywhere) were only available as optional equipment on some cars - many models didn't even have them as an option. It's really kind of mind-bending to think about. I'm not sure if this would work (and even less sure that it might be acceptable by child safety standards); but, looking at the 'ible, I wonder if 2 of the 3 side panels of the crate that are now stacked into the seat (presumably so that it can bear the weight of an adult) could instead be hung down on either side of the rear bicycle wheel to act as foot/wheel guards. They'd have to be fastened securely somehow, and I'm not sure just how the dimensions would work out...

i have a bike in thailand that transport 2 people but scince i came to ameriac i wanted to do this.....so thank this helpful to me ^_

[yaeliv]

no problems :) my pleasure.... if there any chance that you have pictures of your bike from Thailand, I will be happy if you can send my one, just out of curiosity... [e-mail] thanks and good luck!

[mntbkrguy]

You did a very good job with this but I must add an additional word of caution. lower end bicycle wheels found on most comfort, hybrids, and anything you buy from a department store will not be able to support the added weight and will definitely go out of true and possibly break.

[username285]

This project is ingenious and well executed. My only suggestion would be to put some foot pegs in the rear axle so the passenger's feet don't just have to dangle down. It would probably be easiest to pick up a set of commercial ones made for BMX bikes.

[PKM]

Alternative- many bike frames can be pedaled from the pannier position (I used to do it when I had to ride my mum's bike around, pretending it was a chopper :P), so put some pegs on the front wheel so you can rest once in a while and let your passenger do some of the pedaling :)

[yaeliv]

thank you very much! I tried to use minimum equipment that required for transporting anther person on the bike. Because this seat is designated for adults, the angle of their legs doesn't able to use standard foot pegs. I use this bike as passenger for almost an hour, and it's quite comfortable :)

[oakback]

You could clamp some pegs to the seat stays (perhaps halfway between the seat post and the rear axle). Even lead pipe or wooden dowels could be used, but the hard part would be making it able to fold up so as to limit impalement during a 1-rider wreck.

[PlayPatterns]

Great idea on a stylin bike. I'm digging the horn.

[hack124x768]

We've done this before. The front tire had a hard time staying on the ground...

[bufalloo]

does this do anything to the stability of the bike or the back tire? or would a normal weight person added on have little effect on the tire pressure, bike frame, etc.?

[yaeliv]

the weight of anther person sure effects the stability of the bike, and it take few minutes to get use to the new condition.

[Eirinn]

I really like this, too bad riding 2 on a normal bicycle is illegal where i'm from afaik.

[DCA]

Nice Instructable - Very clever use of common materials to make something useful that would otherwise cost a fair amount. Thanks!

[yaeliv]

Thanks :-) Hope you'll enjoy it!

[mikeasaurus]

Wow! This is very clever. Well documented, a great idea, and executed!
Looks kinda comfy.

[Kiteman]

What oddly-small photos - have you published this elsewhere before?
