Buggy Rollin at 120 kph in the Jura Mountains (France)

Buggy Rollin at 120 kph in the Jura Mountains (France)

After a whole day of thinking and a first downhill speed record at 116 kph, Buggy Rollin (Jean-Yves Blondeau) was intent on breaking his own record. Here he goes again for top speed downhill in the Jura Mountains. Story…

A few modifications in order to bring more speed?

"Yesterday, at the end of the attempts at record breaking, it was late and I was lacking light. I was a bit disappointed to have only reached the speed of the previous record (116 kph)… exactly the same speed, that is quite surprising! I wanted to try again… my driver suggested to try at midday.

I go to sleep wondering what I can do to go faster:

  • Taking off the protective gear? No, I do not want to enter this game and end up with a only lycra on like some skaters. Stupid risk.
  • Taping what sticks out like speed skiers? Gaffer tape on all the joints? Not genuine enough.
  • Taking off the useless stuff? That is an option! There are some camera fixings sticking out, I already shot some photos, I can do without.
  • Is is going to be enough? Last time, the GPS was behind my thigh in the turbulence. It is not a bad thing but I'd rather have it on my back, it is easier to check.
  • Maybe I should put the GPS diagonally for its edges to be at 45° instead of being head-on? Yes, alright…
  • And what about the wheels? I had been waiting for new Matter wheels which never arrived… the breaking is ok. Maybe I can put back speed skating wheels at the knees instead of longboard wheels… Yes indeed!
  • Are the bearings clean? In fact, I have no idea.

The next day…

The night goes by and I have a few doubts as for the possible improvements, the weather, the traffic… We go downhill on an open road on a former national road (aouch!) Will it even be possible to have a second try…?

The weather is nice. The driver is ok to try again. He found me some WD40 and silicon lubricant… Not bad! It can work. I check the roller-skate wheels. Perfect. I change the wheels at the knees.

First try. It rolls even less that before! Do it again… That is better! I have a look at the plastron wheels. Not that good. I clean up, lubricate, I get uphill, it creaks… Noise? I resume the inspection. I turn the discs… It was it! It works!

Oops, it is already time! We jump on the car, I stick the camera on the front, I quickly slip on the armor…

Damn, there are cars in line behind a mobile home. What a pain! It is slow, it makes traffic jam… we have to give time to the road to digest all those big bites. Nobody in front for a minute. Nothing behind. Let's go!  We shoot off from uphill. We really start from the highest point and it is completely flat. You have push hard.


And let's go!  Still two double pushes and I go flat on the ground. Big sunny weather, I can see everything.

AAAAh! A car is waiting to come out! Hopefully, it saw us and waits.

As I can see clearly, I take the closest lines to the grass on the right. I lick the white line on the left. Everything is fine. It is still very impressive but it is less frightening than in the dark of the night.

There's a shock, like yesterday. I don't know what it is. Once again, I didn't see anything, it must be a joint in the asphalt. I am so close to the ground that it does not show.

The road plunges. I have the feeling of flying above the asphalt, It goes faster and faster. If I lower my head a bit, I can feel the wind getting in my back. I adjust the position for it to caress without ripping. Just like the breeze, I go… by the way, I slow down my breathing, it is useless to hyperventilate. In the end, I enter the compression. I open my arms.. Wow! What an air brake! I did not remember that the air made such a pressure yesterday…

I clear the road. I have doubts. Not sure I went faster. I undo the back of the armor.

I look at the GPS. 120 kph! "
