Calibrating a bicycle 'computer'..

Sorry, you lost me! I'm a do it all by the book type of gal! Have you tried looking for the manual on the net?

My GPS gives me distance to turns up to a k away so why do you need that

You could go back to where you bought it and ask them to copy the instructions out of another one.
Or as David says try the net

hi signman

talk about a cunnundrum
i have a cats-eye cycle computor and i am curious as to how your going to get it to work off the tailshaft of your 4wd
mine uses the circumference of the cycle wheel which is then entered via a calculation conversion factor chart
to allow it to calibrate distance and speed
so how is the spining tailshaft going a substitute for a cycle wheel to enable the bike comp to calibrate the
distance/speed acurately
are you going to use the circumference of your 4by's tyres via the conversion factor chart
i am not saying it wont work because i quiet often think outside the normal circle of possibilities
because it may well do so and and but

but
it may be easyier to get your wife to ride the bl--dy bike along the road and give her a 2way radio for communications

give her a gps for xmas instead of the tradition gift

if she wants to keep that much of a check on ya
or let her drive ?????
talk about handbrake problems
rofl lol
cheers

Ah the calibration will be the circumference of the tyre however the rear diff is going to make this vary dependant on the ratio. So the best method will be to set the tail shaft so that the magnet is next to the pick up, mark the outside of the tyre where it touches the ground with a marker and then rotate the drive shaft through one full revolution and then mark the tyre again where it touches the ground. Now measure the distance between the two marks on the tyre by rolling it to from one mark to the next and take this distance directly into the circumference value of the bike computer and presto you should be reading the right speed.

PS: The bike computer will most likely have a reset/settings button on the back so have a look there or go the brand into Google and look for a manual.

I googled Adura and Andura and only came up with this

Only thing that came near

Nothing under Adura

My Repco brand cycle computer gets reset when the battery is removed. When it is powered on next, it wants the date & time, and the wheel circumference re-entered. Try removing your battery.
