If the 2 sensors are too far from each other then they cant detect each other but it doesn't matter where on the wheel you put it. The sensor on the bike doesn't need to be near the rim of the tyre and it is alright to put the sensor on the wheel somewhere were it will fit. The computer counts the number of times the wheel turns around and then works out what speed you are going from that. If you think about it if it was worked out by the number of times the sensor went past the bike sensor it would not be able to tell if you was going fast or slow.

It is important to get the censor close enough to magnet so that the sensor detects the magnet. In some instances the magnet is detected with a gap over 5 mm. If you are having difficulty getting the system to work please contact your local halfords store for a fitting demonstration on your bike. Fitting is also available

Question
This will not turn off
It says in the instructions that this will turn off after 10 minutes of inactivity, I just brought the computer back to the shop and they exchanged it for another and this one will not turn off either, I don't want to have to keep taking the battery out and in everytime I go out for a cycle as you need to setup the time and wheel size.

Bear in mind the unit (or at least mine) never turns off completely. It just sits displaying time like a watch. I think that is correct.

The calculation is total wheel height in MM by 3.14
For a wheel size of 26" * 2.0 the figure is 2114
For a wheel size of 26" * 2.215 the figure is 2133
The figure you require therefore will be somewhere in the middle (Approx 2123)

Question
What is auto scan?
I intend to but a new bike computer in the near future and would have appreciated a buyers guide but 'hey hey' next best to ask, so what is auto scan please, I am looking for something un-complicated, does as asked, the £16.99 Halfords wireless one sounded good until I read the review about not picking up a signal.
Any advise? Also I still have the cables from a previous Halfords computer on my Raliegh Max would they work for a new one without the fuss of refitting?

We sell thousands of these a year and have very little negative feedback. It is better to use the new cables with the new unit

The wheel size should be printed on the side of your Tyre. e.g. 24", 26", 700C. This can be then used in conjunction with the inductions to find the wheels circumference which is then entered into the Bike Computer.
Alternatively if you cant find the wheel size, you can measure the circumference of the bike wheel with a piece of string and tape measure, and then input the circumference (in mm) into the cycle computer.

A manual for the Halfords 12 Function Bike Computer is available at ( http://www.halfords.com/wcsstore/li... ) The closest wheel size in the manual is 26x1 with a radius of 1973mm. For a more accurate size of your wheel it is possible to measure the radius of your tyre with a tape measure and piece of string top give you an exact radius. The radius should them be entered into the cycle computer as mm.
