yeah... just picked one of these up the other day when i saw it at wally world for 10 bucks... too cheap to pass up. Damn if those little chineese kids didnt do a kickass job, the thing is so awesome. i put in the circ. of my tire in mm so you know its gotta be accurate? right?

i definitely consider this to be absolutely correct for speed. its so nice for tuning, you can use the trip timer for doing 0-30 times.. max speed, all sorts of odometer functions....

who has these? what models? what do you like about 'em? can we consider this to be 'official' speed? it has to be dead on right?

No I don't think its as accurate as GPS. Better than stock speedos though.

I've had a cateye mity 8- it's as accurate as you can set it.

Fuck if I'm going to buy a GPS to brag on the internet about how fast I'm not.

I have one on each of my peds.

They can be set dead on pretty easily and have rediculous top speeds.

They also mount up in no time.

I use a sigma sport BC1606Lwith the backlight on my fast bikes and the BC506 on my slower bikes.

They make telling if performance mods are effective simple and quantifiable...

It's as accurate as you make it, meaning you have to program it for the installed distance of the sensors and such, and I also believe they have tended to get some interference from the spark plugs.

i think the wireless ones get f'd up by the spark plug... maybe? i dunno, mine has been balls on accurate from what i can tell. i measured around the tire with a string, measured in inches, and converted to mm. if its measuring one click every revolution, and multiplying it by the circumference, divided by time.. how can that be wrong? i've worked with GPS with some school stuff before and i know for a fact that it can be off in terms of speed readings. i think the bike speedo is much more sound in theory. plus the one i have is capable of reading up to 99.9 mph, so the processor resolution must be fast enough for accurate readings at 30 mph.

i really really wish i had a back light though, thats really killing me, but what do you want for ten bucks.. seriously? i should just wire a lightbulb to sit above it, or take the face out of a stock puch speedo and put the bike computer in there.

graham ive got the same one.. schwinn right? havent been disapointed yet. i crave a backlight as well...

ive never pitted it up against a GPS or another vehicle, so i cant vouche for is accuracy but im with ya. i guess its as accurate as the quality of the components.. you never know when it misses a revolution or counts a revolution twice, etc. obviously an error every now and then, but again, you have no way of knowing how often it messes up.

i love mine though.

mine is pretty much dead-on to my truck. i should borrow my friend's gps and do a side-by-side sometime.

iphones do not work for gps speed readings.

i had a wireless one from walmart and i hated it.

lost all the shit for it and it never ran right.

i could never get it synced up right.

so i went to the bike shop and got a wired cat eye one.

i love it. its so nice to know your speed.

only problem is there is no light for night riding.

GPS is really inaccurate unless you are able to use the encrypted military bandwidth. I'd trust a radar gun's or bike speedo's reading over the gps, assuming there is no interference with the electrical.

I have a $10 schwinn from target.....dead nuts on as long as you accurately measure your tire. My only beef compared to a stock speedo is that it isn't "real time", mine only calculates every second or so.....so you can jump from 35 to 45 and have a hard time reading in between if you you are mashing. If you were to buy a really good one I'm sure it would be more "real time".

$10 worth of awesomeness if you need a cheap accurate way to check your speed. I actually was getting ready to get another one here real soon.

Possibly set on KM/H or the tire size was set wrong. No way even a crappy awful one would read wrong like that. It is as easy as setting the tire size and the computer does a simple calculation as to how may times the magnet passes the sensor. Simple.

They did something wrong.....not the computer.
