Soapbox car Femø
Some wood, a old bicycle,a nd fun with the kids

Some years ago I had a summerhouse on a little Danish Iisland called Femø.
On our way there we spottet a old bike, so we put it in the trunk of the car.
I allready had some wheels ready, so the project was ready to take of.
So this is a pedal powered version of a soapbox car.
It’s my daughter Mathilde, and my X-girlfriends son Rasmus.

Feel free to ask questions.

Her you can see another model we build recently Soapbox car (the kids in the workshop).
Or the soapbox car blog for the details.

Hope it can be to some inspiration,

That is cool!! I agree with Patron too. This beats all those battery powered toy vehicles.

Mads, I take it the 15 on the front is the age limit for the car. It can’t be how far it will go, it looks far too well constructed for that. The propulsion system looks good (for the driver at least) and very green. Oh I get it 15Km is how far the guy at the back can go before turning green and falling over. lol

Good project and dont the kids look like they’re enjoying it too.

ps Don’t tell my wife about this design. It could kill me, lol.

Mind you if the oil does run out before we find an alternative this could be all of us in 10 years time!

Looks like they are having fun!
They have jackets on. Must be chilly there.
With the temperatures were having now, I would have to go with the dragon racer next to them.

Rube Goldberg would be proud. That is one fine contraption that you have there Mads. It reminds me once more of some of the crazy things we built when we were kids. It’s a wonder we survived. I’m sure yours is much better designed and built than what we came up with though.

Sorry to bombard you with post these days…
Patron: Yes it’s not a bad idea, I mights have to work a little on the design. I find it a little hard to imagine a CEO on his way to work in one of these…
Eric: Yes we are 100 percent co2 neutral, except from a little bio gas realesed, when we have eaten onions.
Dennis: No the back wheels are simply for the steap curves, since the grivity made the kids hang sideways.
Aurora: Merci, I’m in Paris!!!
Martyn: Can I have your wifes email please! ;-)
And yes in 10 years I’ll be a multi millionar selling pedalpowered soapbox cars, no doubt about this.
John: It’s a old picture, but Denmark are in the North, so yes, we suffer from cold more than heat. But perhaps if I add a whip to the car, they will get the heat back while stamping the pedals.
Jim: Thank you mate.
Flemming: No, it was acually a sign I got from my grandfathers auto shop when I was a kid, so my concious are relativly clean.
Frog: Yes thats a wonderful Idea, a new purpose for the grease box. I laugh.
docholladay: This car was not so stabile thats why it got extra wheels in the back, but it was lots of fun.
I did not know Rube Goldberg, but just checked him out, he is wonderful, just my kind of inventer. I will look for his cartoons now. Thank you. In Denmark we had a guy called Storm P, who was this type.
Billy J: Yes we had plenty of smiles that summer.
TJ: We had a dog also when I was a kid, and this dog also loved to power us, on bicycles and all our strange inventions.
Thank you for all the comments,
