Every time I lock up near Clark and Washington I notice that my wireless bike computer thinks it is travelling fast, like 30, 60 or even 90 mph. The numbers move around as I pick up the device to take it off my bike. The device still thinks it is moving fast after it is in my hand and no longer on the bike. (I bring all loose items such as lights, computer etc, in with me.) My trip from home is a little over a mile longer than what i actually traveled. and the average speed has increased by a few mph. My computer says today's max speed was 80 mph. My watch, which also measures speed, says the max was 18.1.
Does anybody know of some kind of weird magnetic field in the loop? I have noticed this ever since I got a wireless computer a few years ago. I thought that perhaps it would change with ll the construction on Washington. No change. Is the CIA or some nefarious group of infiltrators hacking all our phones? Are aliens going to beam me up and will they have those probes? Did some contractor bury something back when the building was built? Does the hustle and bustle of the loop provide it's own energy? Is there a portal to another dimension atop the Picasso? Or is there a more mundane reason such as traffic light control or some other public utility thing nestled nearby?
Phantom increase of speed has led to an imaginary expansion of the imagination.
You're not alone David. Both my wife's and my Cateye wireless computers will jump like that at some stoplights, under power lines, or other unknown places during a ride. But it is a fairly rare occurrence. We have different models. Her's has hit maximum speeds in the 90's, and mine has hit as high as 110 mph. Before that happened, I did not realize that the Cateye was even capable of displaying a three digit speed.
For those of you having odd problems with your wireless computers, I would be interested in knowing what material your bikes are made of. I'm wondering if they are acting as antennas, picking up the many strong electronic signals in the Loop and causing problems with the computers through a non-contact induction effect. This would not occur with a carbon fiber bike, and wouldn't occur much with a steel bike. However, aluminum is a good antenna material, and could conceivably cause such a phenomenon. Just a thought, and maybe a dumb one at that.
Both my wife's and my bikes (at least the one's with wireless computers mounted) are steel bikes. Hers Reynolds 853, mine Bianchi steel.
Well, so much for that theory!
