Road Cycling - Transferring a computer to another bike

I really want one of those computers that record cadence, speed, mileage, etc., and I am about to buy one, but the problem is that I'm probally going to get a new bike next month or sometime soon. Should I buy the computer now and transfer it to my new bike when I get it, or would that be impossible / extremely difficult?

There will be no problem transferring the old computer to a new bike. You may have to recalibrate it for the new wheels but that's not difficult. If the wheels are the same, there is no problem, and if you are keeping the old bike, you can just buy a new harness and use the same computer on both bikes.

Buy a Sigma 1200 or higher cordless version. Then buy another cordless holder and you can just switch the counter, and decide what bike you want to use. There are two separate settings, for each bike.
And anotjer thing, Sigma Cordless does not support cadence, so if you need it, buy wired version, but cordless is much better.

I asked the question because when I was in middle school, I bought an old-school analog speedometer for my mountian bike. I remember to install it you had to take the wheel off and install this plastic wheel thing to the hub. It was not something that could be transferred from one bike to another. After looking around, I learned that these newer electronic models, its not the case.

Tomi: Actually, while I was shopping around, I noticed some places saying that the RCS wireless upgrade has been redisigned so it can now work along with the cadence upgrade. I want cadence, which is why I chose the 1400, and now if I wanted to upgrade to wireless later on (not now because I don't have the money), its still an option for me.

my understanding is that there's no such thing as a wireless cadence computer. a wireless machine can do speed/distance/etc, but requires a wired adapter to do cadence. just do cadence the old fashioned way- you've got a timer on your computer, and you can count. kinda like taking your pulse...
