A note on shopping carts: Please don't steal them. This one happened to be floating around our downtown area for over a week before I grabbed it. The bicycle is almost ten years old and still works fine but I just bought the bike shop in town so suddenly have access to plenty of cycling materials.

lets settle some disputes here,
don't go to a store and take their brand new shopping carts. Go inside and request to speak to the owner or a manager and ask if they have any older shopping carts that they can sell or give you or a way to acquire one. Some may give you a few to choose from while others will say no. There is probably one out stuck in a lake, rusting. Go and help your community and pull it out and put it to use! If those aren't options and there isn't a dump near you, weld/make one! I am sure you can learn a new skill, to weld! it would probably be lots of tacking, but a good way to practice! or maybe you are confident in your lashing abilities and the strength of bamboo and make one that way. Maybe you make one out of composite material! the simplest way would be to form it to the shape you want or to attach the sheets to form a box and drill holes in it. There are so many alternatives!
and as to him with no helmet and flip flops, it isn't the safest thing but there is no reason to argue about it.
also it would be very innovative to attach the handle of the cart to a sets of wheels with a rod to make them turn! like how go carts turn.
I don´t think the first comment was inappropriate.
I thin kyou need a new username, because obviously you arn't "easily amused".
also i would weld the back flap on the cart closed and remove the child seat. and for a more permanent fixture to the forks maybe a metal rod secured through some holes drilled in the carts frame and locked on with some nuts or bent around the cart frame and welded on?
My suggestions.
Replace the carts rear wheels with rollerskate or even better, large kickboard wheels.(be sure they don't swivel...)
Seriously fix the bikes fork to the cart. (cable ties won't do...)
Mount the cart at a angle, so only the rear wheels touch ground while riding. (front wheels some 2-5 inches above ground, this way you can load and unload whithout the whole thing tipping over.)
Seems to me you are comprimising the ridability of the bike and your safety by using the shopping trolley on the front end. If the basket is what you want then wouldn't it be safer to hack the unroadworthy trolley wheels and frame off, get a short axle and put some bicycle wheels (or lightweight bigger diameter wheels) onto the basket, then fashion a tube hitch and use it as a bicycle trailer?
Probem with this design is that shopping trolleys are relatively heavy, and only designed for short trips on smoothish surfaces. For anything to do with bikes you want something as lightweight as possible.
Years ago, when people still returned shopping carts back to the front of the store, I was doing just that, and because I was in a hurry, I was moving at a pretty good trot, and I hit a nicely cut little trench cut into the pavement of the parking lot, filled with asphalt to a couple of inches below the rest of the pavement. The handle of the cart got rammed back into my stomach, pinning my hands to my stomach, and I went head first into the cart as it went end over end with me in it.
Having entertained my friends during my misspent youth by taking head-first tumbles down staircases and walking away as if nothing happened, I was well prepared for the shopping-cart mishap, and didn't get hurt, but for those without specialized skills for rolling around on pavement, this sort of thing could be painful, especially with the higher speed of a bicycle.
This bike requires more alertness to conditions than most, and while it might be OK for short trips, ti wouldn't be good for commuting. Safety-wise, this project has "Don't try this at home" written all over it. But other-wise, it shows some great, um, imagination.
This if done is a dangerous "conversion".. Hit any bump or even a small hole and wipe out..
Oh wait... omg

Here in Texas 8 to 10 years ago, shopping cart THEFT got so bad that the various industry trade lobbiests for the different stores that use shopping carts, got the Texas Legislature to enact a STATUTE making shopping cart theft A FELONY!!!!! And the statute had the "PRESUMPTIVE" CLAUSE in it which means that whether your intent was to steal the cart, or not, IF you posess it OFF of the store's property, THEN you ARE PRESUMED to have known that you were stealing it.
It does NOT MATTER if someone else took it off the property, and you "just rescued" it from the street, in Texas possesing a shopping cart off of the owner's premises is a felony.
And by the way a similar law applies to ANY railroad rails, ties, or scraps along the RR right-of-way! The railroad companies say anything they leave / store on their right-of-way is THEIRS, and removing it is stealing! And other similar laws
similarly apply to plastic MILK "CRATES" and plastic soft drink bottle "trays."
And a couple of years back, Louisiana passed a strict new TRESSPASSING law that says, that IF YOU ARE ON PROPERTY that you KNOW IS NOT YOURS, AND you DON'T HAVE SPECIFIC PERMISSION OF THE OWNER, THEN YOU ARE TRESPASSING.
These newer laws take the "fudge fact\or" [quibbling] out of law enforcement protection of people's property rights.
