I finally got a computer!
 

Yeah... so I decided to start a whole thread about it.. hehe :o

Just thought I would share my excitement. I can finally see how many miles I'm racking up.

This morning's commute:

Total Distance: 10.46mi
Total Time: 0.42.11
Average Speed: 14.7mph
Max Speed: 30.0mph

yay me! :D


I'm also hoping to get a new mountain bike (not for commuting) in the next couple weeks... but we'll save that for another thread :)

Ok...so what's the brand...

Nothing special, just a Cateye Enduro 8. I'm just happy I can watch the miles tick by now. :)

You will love every ticking second of it .... congratulations. Bike puters rules

yeah I like Cateye too, especially those large display numbers.
I have the Enduro model on my hybrid commuter & an Astrale 8 on the road C'dale, both calibrated properly to the tire size (printed on sidewalls)

According to one, work distance is 9.14 miles, the other claims 10.2 miles on same route. I am trying to figure out which one is the liar.

For maximum accuracy, you'll need to do a roll-out. Mark a spot at the bottom of the tire, roll the bike along a straight line, and note when the spot is again at the bottom of the tire. The distance between the two locations along the straight line is the circumference of the tire, which you'll enter into the computer. Do this as carefully as possible for each bike, and you'll probably find the ride distances for each computer to be very close to one another.

You know if you tweek the tire calibration setting you can go faster. In fact, if you set the tire diameter to 0... you'll hit the speed of light! Then you'll save a lot of money because you won't need a light system. But on the flip side, it makes everything farther away.

Anyways, be careful of the bear.

Calibrating it around a .0000299mm wheel would pretty easily let you reach light speed.
If you set the diameter to 0 you'd be going infinitely fast, which is obviously impossible.

you'd have to make the number bigger to go faster, not smaller ;)

yeah I did the rollout 3 times to make sure I measured it just right. The chart that came with the cateye said that my 26x1.5 tires would have a 201cm rollout. Mine are actually 199 (slicks). So if I had gone by their chart I'd be getting an extra 2cm per revolution of the wheel on the odo. ...I guess that could add up :)

Aw son of a...

14932495936mm should about do it.

Hehe

No wonder there's some people claiming average speeds of 25 mph barely breaking a sweat
;)

you do realize that as you approach the speed of light, you will be absorbing energy at such a rate that you will be VERY VERY VERY HEAVY

(see: E=MC 2)

Yeah, so you'll probably want to be sure to run your tires at maximum pressure.

lol.

well... due to extreme boredome... I did some math.

my 30mph max = 24,261.4673 revolutions per hour.

If my tires had a circumference of 1493249593.6 cm my speed would have actually equalled 225,113,004 mph

Since the actual speed of light is 670,616,629 mph, that wouldn't have quite gotten me there. Need to train more I guess :)

nah... just use air free tires :)

How about this then. Setting the tire diameter really really large. Sure, you won't make much speed. But you'll get incredible distance. Infact, you would already be there and... you won't have the weight gain.

Either way, you still have to watch out for the bear.

I think you got it wrong, believe me been there done that: as you approach to the speed of light time slows down dramatically. Its weird, the faster you pedal the slower time passes by, causing you to arrive late to work every time.

Please dont' try that unless a pinky slip is desired.

Sorry, my figure was for wheel diameter. Rollout would need to be that times pi.

Did you do the rollout while sitting on the bike, to account for tire deflection? That changed mine 1 cm.

To look fast, just switch to kilometres.

actually going faster is much easier to obtain
simplay attache an extra magnet to each of the spokes on that side of the wheel
send more signals
more signals

speaking of experiments... here's one:

Attach a magneto generator to your bike and terminate it on your handle bars, or better, your butt cheek
as you go faster, more current is directed to your body (not so much that your health is impaired... just a tingle)
Question: how fast will you go until you have to slow down to deal with the current/tingle?
Can you adapt to the tingle?

HA funny you mentioned this.

I just got my Cateye 'puter this weekend, and took it out for a test spin. Just rolling down the neighborhood bike path, I was coasting at 15 and accelerating to 25 and up without really breathing hard.

I was so proud of myself for a while. Then I realized that I had logged 5 on the odometer, just biking around the 'hood. I started to get a little suspicious.

Ahhhhh, kmh is a whole lot different from mph.

D'oh.

Oh well, I was flippin FAST for a while there.

Don't trust that technology y'all! The govamint wants us to all have computers on us so they can keep track of us and clip our bike chains as soon as we lock up to a sign post! It's all part of the oil conspiracy to make us use cars instead of bikes! Throw them computers away! They monitoring what I'm writing right now and the doorbell just rang and it's probably the FBI!

I did the same this weekend. Wow! I'm going 30 on my MTB! Wait...Doh!
