Should be quite easy sitting there (not that I'd try it - don't think my top gear is high enough!). Dangerous though if the truck brakes...


Or trains are good(ish) too: mile-a-minute

I've just had a quick look and can't find any real diagrams for it (just a 5 minute search though), but wouldn't there be almost like a vacuum created behind the truck if he was close enough?

I know when I was on my 125 and using motorways I'd get behind a truck and it meant a change from full throttle to about 1/4 to maintain the same speed.

Yes it's late so I probably don't have a clue what I'm talking about

Especially if the bloke behind you is busy pissing about with his phone rather than watching the road.

The biggesdt obsticale to overcome on a pushbike is the atmosphere. There is a record for some dude on a pushbike topping over 200MPH behind a screen

I could catch the fucker on my ped.

It's not the actions of the truck driver that pose the biggest danger, it's hitting one of many of the thousands of bad potholes belgium has on it's motorways. I have a horrific time on a motorbike with them, I dare say if he hit one, he'd end up a complete mess.

Does it literally pull you along or do you need to be peddling as well?

A bit of both I imagine, I was coming home from work one night and was overtaken by a national express coach and just at the point it was passing me I could feel the bike being dragged a couple of miles an hour faster

I regularly do this with buses and lorries - they can drag you along at 40mph no bother.

You do need to pedal a little bit, but not very much at all, the key is keeping in the sweet spot, which is not more than 6-10 feet from the back of the vehicle. You need to be aware of the vehicle's acceleration, so you can put in bursts of high effort to keep in the sweet spot, but then it pretty much pulls you along.

I've never yet had an 'O shit!' moment, I always ride on the drops so I can have full braking ability, and keep my eyes glued on the brake lights and listening for engine note.

Needless to say I only do it on roads which I know are straight and lack significant obstacles.

I can brake pretty hard, and I'm not likely to damage a lorry or bus if I plough into the back. The main concern is hitting the back, falling off, then getting run over by a following car. Tho they tend to keep a good distance when they see some dickhead tailgating a lorry on a pushbike. Laughing

Up to about 12MPH most energy is used to move the mass of bike and pedalist against friction (and tyre resistance). After this you meet the solid wall of air. This is why race bikes drop the bars and the pedalists tuck-in.
In the tow we lose the resistance of air the mass is then moving in a region of 'moving' air. If you can pedal fast enough you can stay within the bubble.

Drag is slightly different and it where the surrounding air rushes in to the 'low' pressure bubble.

Slipstreaming.

https://en.wikipedia.org/wiki/Slipstream

All racers use slipstreaming, basically, to save energy.

I get loads of folk slipstreaming me as I am always in front of the pack. Cool
Very Happy
