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. :-(

I'm really glad I'm comfortable riding when it's below freezing.
Otherwise I'd miss about 1/2 of the year riding here.

Batteries losing power when really cold is the main reason I'm staying
with an external battery pack headlight on my bikes.

Cheers


If anything surely a external should be more prone to cold since it’s
removed from most heat sources, though in practice the size of a external
should protect it, I have both systems and neither shows any effect which
is probably down to the size of the battery packs be they external or
internal.

The wee Garmin I use on the commute most definitely does get effected by
cold, as the temperature reduces to zero so the battery level drops, again
my older larger Garmin Touring is not noticeably effected by cold.
