Hi
a buddy of mine has been using the Sigma Rox 9.1 for measuring power but stumbled into this ibike Newton meter.
Has anyone tried this?
I believe it can calculate real time CdA if used with a power meter, that sounds cool to me, but at that price, just using the force calculations to estimate your power, its just not accurate enough.
I stumbled across his product today and am really curious how it compares? Would love to be able to use power on both of my bikes. Haven’t found any concrete comparisons online yet.
Howdy! So I’ve had my iBike Newton for about 3 weeks now and right off the bat let me say that I love their new software (it works with all iBike’s too…not just the Newton). Anyways, like my SRM and other power meters, I do tend to put the filter on the 5 or 10 second averaging (which avoids second to second update of power…too all over the place on ALL power meters by the way…but it still records and downloads it for analysis). Again, I do have my SRM amateur and in comparison with just the power taken into account, it is almost dead on! For all I know, the iBike may be the more accurate (people/I would assume it would lean toward the SRM being more accurate, but this just may not be the truth). I do know that there is new technologies in the Newton vs. the Gen 3 iBikes of 2012 and pre, like much faster and better accelerometers and different wind port sensors (and it’s USB rechargeable vs. battery). I truly love the unit! I train off of power all the time so need to know it’s accurate and immediate on data that I’m seeing. Super easy navigation (but to be fair, I have been using iBike as my head unit with my SRM for quite some time, so it is second nature to me now). Hope this helps. I do not use EVERY feature in the power unit and I do now use the iBike Newton without my SRM cranks because I found it plenty accurate enough to train and race off of.
Oh, and I have my iAero (was like $799 in 2011-2012) that I’m selling now. Nothing wrong with it (looks new), just do not need to power meters. If you know anyone who wants it (iAero, USB download port, speed/cadence sensor)…selling for like $175 complete!
how does your iaero hook up to your bike? i cant seem to find anything on goole telling me how it measures power…
anyone hear of the new stages power meters on the cranks? what are your thoughts since they are sooo new?
The iAero is the same as the Newton in what it takes in to measure power output (wind resistance, slope, acceleration/deceleration variances…). The iAero can analyze your position on the bike as well to help find the most efficient position for your output. It looks almost identical to the iBike Newton and mounts the same way. Handlebar mount that I think can be mounted on the stem as well. It comes with speed/cadence, USB for downloads handlebar mount and of course, the white (red button) iAero.
Awesome. thanks for the clarity.
I’m interested in your iaero.

All good…hit me with any questions you might have. I sent it to Tom Gore (at iBike) last month to assure the accelerometers are exact and set…he assured they were perfect. You can message me whenever or email me at offthebackagain@live.com.
I assume the iBike needs clean air to be as accurate as possible. For those riding on aerobars, where is the best place to mount the iBike? The steerer tube mount is nice but I would think the air is pretty dirty/turbulent since it’s coming off the hand position up front on the aerobars.
I purchased a Gen III Remote Wind Sensor for mine so that when I use aero bars, I can mount iBike in normal stem or bar area and it is simply a tube that you take out to the front of your aerobars to get the “clean” air. Simple easy and effective accessory for like $54. http://store.ibikesports.com/accessories-parts/gen-iii-remote-wind-sensor
