My question is: is it wireless? and if so, will it have a mind of its own like my heart rate monitor near a high-tension power line.

It sure would be a drag climbing a steep hill and it decides to shift up into a higher gear like 13 cog. would be an understatement. or what happens if the battery goes dead.

Reminds me of my electronic dash board in my car. Now that it has over 200,000 miles on it, half of the electronic displays are kaput. And I don't trust the gas gauge anymore so I have to keep a log of miles travelled from last fill-up.
