Speedometer from the world of bicycles

My speedometer, subject to exaggeration and shaky-needle syndrome has
been fired. I aim to replace it with one of the magnetic-pulse driven
computers that bicyclists use. I have seen them on a number of
motorbikes, as they are light, reliable and can be calibrated very
accurately.

Does anyone here have a suggestion on a good brand to get? Looking for
large, readable numerals and possibly a lighted display.

Thanks in advance.

 

The Sigma BC600 or BC800 is exactly what you are looking for with
the exception of the lighted display. Aerostich sells the BC800 with
an extra long cable (you'll need this as the std. cable is not long
enough to reach from the front wheel up to the bars) for $23.00 and
an auxiliary light for $7.00. I have used the BC600 and BC800 on two
motorcycles and can vouch for their accuracy and ease of installation.
Supposedly they are good to 300km/hr (186 mph), but I can only confirm
that they will in fact work up to *cough* mph. Some of the bicycle
speedos will only work up to 100 mph or even less.

http://www.aerostich.com/riderwearhouse.store and search for PN 2123 or
'sigma' and you'll find it.

If money is no object, get a GPS instead, but you'll have to take
it off the bike or stow it every time you park to avoid losing it.
The Sigma is cheap enough that you don't have to worry about taking it
off the bike. It does come out of its quick-release mount if you feel
like taking it with you, and it is about the size of a small cookie,
so it fits easily in the smallest of pockets.

 

I've the BC800 installed on my bike too, and it works great.

Before the BC800, I'd a spare Bell bicycle speedo lying around so I
installed in on the bike. After a few hours of riding in the sun, it
crapped out and the LCD display no longer worked. I went about to debugging
the problem and found in the installation guide a fine-print disclaimer
warning against "prolong use in direct sunlight." What bicycle is not
ridden in direct sunlight?! Also, nowhere on the outside of its packaging
did it notify the consumer of this limitation...

It's also good for remembering where you parked when you go to a stadium
or other such place. Just set a waypoint when you leave the car, then
you'll be able to walk straight back to it.
