Why stop at 2 seats...

At 30 miles an hour? sounds like a straight trip to A&E for me...
I'd say 3mpyr is a trip to the hozzie for you, my friend.

Thats too slow... Means i would only be there once every few months...

I suspect this will be quite difficult to do. The camera will most likely be set to 35mph - speed limit +10%+2mph. This is the guideline from ACPO.
Riding in a tight group will save you about 40% power, but this won't translate to as much of a speed increase as you'd expect. Air resistance is proportional to speed squared, which means the power required is proportional to speed cubed. Therefore riding in a group at 35mph will require the same power as riding alone at 29.5mph.
35³ x 0.6 v³
v = 35 ∛0.6
v = 29.5 -
29.5mph pfffff - i never drop below 30mph or my bike explodes. That would make a great hollywood movie, oh wait...

it's only against the law if you have a means to determine your speed, so if you dont have a speedo on your bike your fine, i asked a coppa once.
Have set them off before where i live, 35-40mph is easy there (edit: downhill)
would be up for it for a laugh

The copper was talking shit then.
The speed limits on public roads in the UK apply to motor vehicles only; that's what the appropriate law(s) state.
The only speed limits that do apply to bicycles are due to specific legislation such as the Royal Parks Act that is worded in such a way that it applies the speed limit in the Royal Parks to all vehicles (not just motor vehicles and therefore includes bicycles). This is why the Police are sometimes out enforcing the 20mph speed limit in Richmond Park (and it's 10mph on the path around the outer edges of the park). Also, not knowing your speed isn't a valid defence (although you may get away with it if the copper is feeling nice).
The 'furious cycling' offence is a bit of a misnomer too. There's no record of it existing, although there are some tenuous reports back to the mid 1800s. More on it here: http://www.bikeforall.net/content/cycling_and_the_law.php
Bikes can set off speed cameras, I used to set off the one at the bottom of Orwell Hill (coming in towards Cambridge) whenever I went that route (except into a headwind!).

"The copper was talking shit then."
Well that's what he said, i assume then that he didn't know so made it up!?
-
Well sorry guys but looks like we may have the shelf this one for another time. Lack of people and availability.
Will re-open the thread when another date that more people can make is available.

Since you're after a high enough speed to trigger the Gatso and enough RADAR cross section to be detected at all, you should just mount corner-cube reflectors on the spokes, facing backwards at the top. That way, your main RADAR reflector is doing very nearly twice your road speed, which will be handy as the old big-box Gatsos are often set well above the ACPO 10%+2 recommendation in order to reserve the limited amount of film for the really serious offenders. In a 30mph zone, you will get busted by a cop with a hairdryer for 35, but the Gatso will most likely be set to ignore anything under 40.
-
Tractors doing 20mph will often set off 30mph cameras because the tops of the tyres (with treads that stick out 6" or more) are big enough to reflect back enough of the radar and will be doing 40mph.
o rly? i thought it was closing speed over a set distance?
-
Old school big-box Gatso uses Doppler RADAR to measure speed, and takes 2 photographs 1/2s apart if it detects anything over the set threshold speed. The photographs are stamped with the time, date and measured speed, and the interval between them combined with the road markings allows the data analyst to check the average speed over the 1/2s in order to eliminate spurious readings. It is the pair of photographs which will actually be used as evidence if it ever gets to a court.

The photo would be priceless.
