Anyone here doing anything BICYCLING related?

Sort of. Yesterday I used my folding bike for a short ride.
Turns out the Cateye wireless cyclometer didn't register any
speed or distance. I'm hoping it's just that the sending
unit's battery needs replaced.

This has been a frequent irritation in cold weather. The 20"
wheels and the tall stem make the distance from sender to
display unit fairly large, but still within the supposed
range, according to the manual. But for years I'd have
problems with lost radio contact if the temperature dropped
below 40 F.

Last year or the year before, I decided it was because the
handlebar itself blocked the signal to some degree. I
fabricated a plastic mount to hold the display unit in front
of the handlebar. It seemed to be working until yesterday's
ride, which was right about freezing. I'll change the sender
battery and see if it helps.

But I'm at an age where I no longer enjoy riding much below
40 F. Today I'm fighting off a sore throat, which has been
my usual punishment for a cold weather ride.Â* :-(



The triathlon world uses a computer mount which you can fasten to the
stem just below your handlebar to stay within Cateye's wireless range.

I've played around with a couple other mounting alternatives on this
Bike Friday New World Tourist, pretty similar to this bike:

I first fabricated a mount like the one you showed to hold the unit
halfway down the stem. But the cyclometer was in an unprotected position
during the folding process and kept getting knocked off. (That long stem
pulls out of the headset for folding, and just sort of hangs alongside
the folded bike.)

I tried zip-tying the cyclometer mount to the top of the main frame
tube, just behind the headset. But it's really hard to read down there,
especially now that I'm deep into bifocal age. I've also played with
locating the sender in different places on the fork.

I think what I need is a couple parabolic antennas, one at the sender
pointing up, another at the display focused down. Kind of like the
microwave towers.

Interestingly, my wife's identical bike has a much cheaper Echowell
wireless cyclometer. Hers has no problem with cold temperatures.
