Maximum speed

[pfunk12]

During my ride yesterday, my rear derailleur started to act up. It was skipping gears at random. I took it into the shop and while the mechanic was working on it, I asked him if he could also check my computer since that was acting up. A few weeks ago, the mileage was going backwards and then I noticed that during my commute, the distance wasn't accurate. He checked it out and fixed it. I checked it after my ride today and saw that my maximum speed was 57.3 mph!!! So do I take it back to the shop to get it fixed again or do I keep it the way it is and try to see if I can break 100 mph?

Definitely go for 100+

That's funny! My DH's computer sometimes fritz's out and says his maximum speed is 77. Never higher, but he keeps hoping one day it'll say 100.

Is this a wireless computer? Mine sometimes goes nuts and says my speed and cadence are impossibly high. Sometimes also it just stops reading them. Usually this is due to interference from electrical wires.

Although I've never seen it go backwards...

[pfunk12]

Yes, it's a wireless. And you're right - both the mechanics said that high voltage lines could interfere with the computer. I never had interference with the speed until today. I didn't even hit 30 mph on the ride so I was surprised that it said 57.3. Only in my dreams!

Over the summer, I lived in a building that had a proximity card reader (RFID) that you had to "beep" into to use the elevator. I took the elevator to get my bike back upstairs after rides. I guess the RFID reader interfered with my computer, because one day I happened to glance down at it, and it read me as going 84.9 mph! I no longer have it stored in there, because it decided it wanted to die during my ride the week before last, and in doing so, it ate all my numbers.

sure it didn't get switched to km/h somehow?

It was even more fun when I wore the strap for the heart rate monitor, and it would say my pulse was over 250.

One evening this summer after a post-work ride, I put the bike in the car to drive home but forgot to turn off the cycle computer first. I kept hearing it beeping while I was driving home. My car has a smart key feature (you keep the key in your pocket/purse and a sensor in the car allows you to lock/unlock doors and start the car if the key is within a certain distance). It turns out the smart key system was messing with the bike computer.

Oh, Catriona! Don't spoil my fun! Don't slow me down!

I once got up to 85 mph stopped at a traffic light next to a train station.

I was having the same problems and turned out all I needed to do was change out the battery. But it lost all of my miles I've logged on the odometer. But I was surprised I needed to change it so early. I only had 500 miles recorded and it was a little over a month old.

I find that I have to change the batteries on my bike computer far more often than predicted by the manufacturer (cateye). Next time I will get them from a different source. I've been getting them at Radio Shack and alas I don't think their batteries are fresh--at least not the ones of the type I need. Perhaps I can mention Lance's name at the shop and get fresher batteries.

I've noticed several of my electronic gadgets for fitness never have very long battery life. My Garmin was the worst. I had it for maybe 3 months and it started acting up and I had to put new batteries in the watch AND the foot pod.

I have a wireless computer on my commuter and have discovered that the magnetic field from my battery for my light will may my computer wig out. It does the same thing, says I'm going 50 or 80 or something crazy like that It's kinda funny since I'm usually loaded to the max on my hybrid. Oh I can entertain the though anyways

yeh, I had one go bananas while I was installing it. I sort of wanted to keep the max speed on it - 180 km/h, and just offhandedly let it show sometime to a fellow biker.
