Top speed = 45 mph?
 

Why arrive fast when you have a snipper rifle on your shoulder?

Cape Cod??? Rich white kids playing Lacrosse; what possible crimes could there be?

I prefer the fireman:

Well prepared with 2 extinguishers.

Are you kidding? The crime is bad enough that he needs flashers under his handlebars!

WTF, is that a joke!?!?! :eek:

Ask the dude with the rifle. See how funny he thinks it is.

unlimited range

Do they make a whoosh sound when up to speed?

Most importantly does he really need an 11 gear or will a 12 be enough @ 45 mph?

^ ^ The 20 knot winds do all the work. No need to pedal, rider just hangs on.

Now that's some funny **** right there! I think he only needs 12 because 11 would just make him a poser.

I'm sure the mask keeps bugs out of his eyes, but do you think those boots are SPD or Look?

What if he has to tack upwind?

That looks like a great way to wreck

I believe that is the most silly thing I have seen in a week or two.

Bullet proof sail?

SWAT pursuit M-80? :)

Actually the rider probably ends up hurt flat on the ground with 10 knots wind - forget about 20 knots

Probably not very when a wind change slams him and his $1500 plus sniper rifle into the MUP...

Maybe I'm wrong and the tech is solid but sure seems fraught with ugly potential. Funny but ugly. Keep those cameras rolling Cape Cod'rs...

Does the physics of this even work? Even in the best case scenario? I'm trying to imagine a situation in which a sail helps if you're moving faster than the wind, and it isn't working out for me.

So you're saying they need to make an ambulance sail bike, too...?

The apparent wind will be much higher. Google ice boats for an extreme example.

It might, especially with the low rolling resistence of bicycle wheels. Sail boats, and particularly monohauls, have a difficult time going faster than the wind. That's because the hull leans over (heels) and the drag increases and effectively takes away boat speed. Catamarans with dual hulls don't suffer from that problem and can go faster than the actual wind - by moving forward, the boat experiences an "apparent" wind from the front plus the actual wind off to the side that drives the sales. Combine these two vectors and you have a new force that's greater than the actual wind speed.

So it's possible for something like this to go faster than the wind.

Some sailboats can move faster than the prevailing wind... it is physics and design that allow this.
