Bugatti Chiron Pedal Car

UPDATE!!
Got the steering all figured out, and am now moving onto the gears and seats. Had a mishap at first, but I think I got it all figured out now how to keep the gears in line better. Getting very close to a test run :)

UPDATE!!
Gears are now in place, just need a few minor adjustments to make sure everything runs smoothly with them. Last thing to do after that will be to get the seats mounted in and a safety bar put over top the rod that joins the 2 pedal systems together. Oh and the steering wheel too. Then I think it'll be ready for that test run.
Also got some skis for the front tires at an auction for $3. In case I ever want to drive this thing in the snow, cause it snows here like 1/2 of the year. Our four seasons here are Pre-Winter, Winter, Still Winter, and Road Construction.

UPDATE!!
Surprise, the boat chairs were just a place holder for the real seats, office chairs! A lot more comfortable and provide better back support for when pushing back when pedaling. The chairs can also rotate outward, making getting in and out easier once the car body is added. Also added support in the back for the wheels as I was having an issue with the central wheel turning sideways. Steering wheel was also added. A few more changes and I'll be ready for a better test run, as the first one I broke a few welds trying to get it moving.

UPDATE!!
Got to take it out for a second test run, this time everything held together better, but there's still a few issues. It does give me a better understanding of what and where needs better reinforcement for the future. For now, this project might go on hold do to the fast approaching cold weather and snow, but if there is a decent enough break in the Winter months I may work on it some more. I'll also start on the Bugatti shell here soon too, because that I can do inside the workshop in the house.
 
UPDATE!!
Finally the warm...well warmish weather has returned and I can get back to work on the pedal car. Over the Winter I went back to the drawing board for this and figured out how to fix the slipping chain, the syncrhonizing of the pedals, better overall weight distribution, and further structural support. All I needed to fix a lot of it was one more matching bike, problem is they are quite rare these days for this particular model. But right at the end of February I found a 3rd matching bike for sale and immediately bought it. Since I've had a bunch of free time due to the global crisis happening (Check local listings) I got to work on it and had the whole car up and running again in just a week. Changes I made from the previous design were:

-Added a central steel beam to add support and hold a third set of pedals.
-Linked all three sets of pedals to create one continuous moving pedal.
-Moved the 5th drive wheel closer to the seats to help give it more traction, better mounting, and shorten the drive chain.
-Used the back end of the frame to better hold the drive wheel instead of making one myself.
-Added additional cross supports for the front wheels to keep them in place.
-Added further frame support to keep it from wobbling or bouncing as much.
-Added further support to the back end, and a new solid full length bar for the back tires, making them adjustable and easier to change if needed.

Next things to do are add the passenger seat, work out some kinks with the middle pedals not wanting to rotate so easily, grind off the rust, and give it a nice new coat of black paint overall, tires included.

Good idea. If it keeps giving me issues I'll add one, but for now it seems to be holding together better than before.

Multi-speed bikes have an idler sprocket that serves a dual purpose of not only providing chain tension, but switching the gears as well. Maybe you can cannibalize a few more bikes and give it multiple speeds!
 
UPDATE!!
Body is coming along nicely. Got the front end done and am currently finishing up the sides and roof. Going faster and a lot smoother than I original thought so that's good. Looks like I may need to trim down the seats a bit though otherwise it'll look more like a VW Beetle than a Bugatti lol.

I look forward to this project.

I know foam is cool and all, but wouldn't it be cheaper to do the ol' cardstock/fiberglass method?
I mean... you can fiberglass over foam no problem at all! That has my vote! Add in some fiberglass (and maybe carbon fiber accents... it will make you peddle faster)!

I thought fiberglass resin had a tendency to eat foam D:
 
That much fiberglass and resin I'd be lucky if I'd ever get the thing to move lol. Not only that but the cost would be atrocious.

Just add a little at a time, your legs will be so ripped by the time you’ll be done! You’ll be able to compete in Tour De France, it’ll be great! That can be your added revenue.

If you aren’t about bike racing you have a getaway “car” for the bank you’ll have to rob, no cops will chase a Veyron, they’ll never catch it!

Not if you heat seal and then use spray glue or other glue to tack the fiberglass mat. It creates a nice barrier.
