I agree with rattlesnake that the original iBike Pro was finicky to set up. But that was 7 years ago. The Newton, just introduced in June 2012, is the first complete redesign of the original iBike. Digital sensors, integrated rechargeable battery, full wireless, even better accuracy, and improved software are all major improvements. And yes, the Newton is much easier to set up and not at all finicky now. I disagree with kennyg; the Newton is much less expensive than the Polar, and the Newton is far more sensitive. The wheels of progress keep turning; check out the Newton at www.ibikesports.com, and get user reviews at www.ibikeforum.com John Hamann iBike
