Hi all is there a way to bypass the auto shutoff and make it manual only. Thanks for any input Jeff I found out by accident the other day that if you are in "fit train mode" Newton will not auto shutoff I put it in "fit train" towards the end of my commute to time & average ...

Re: Wind sensor problems

I had a similar issue yesterday During my morning ride [it was humid from overnight rain] power went to zero/low numbers for about the last 15mins of the ride. It was still the same for my morning commute (different profile) other than a small period of crazy high numbers And still the same for comm...

41 lbs is only 18.6kg
Assuming you got divide & multiply the wrong way around, correct weight is 90.2kg
Which is actually 198.44 lbs.

Re: Wind Question & how do I correct it?

I find that the wind sometimes "corrects" after doing an 'analyse route'.
Particularly I regularly notice that a tailwind will be corrected to a 'drafting' scenario.
Just thought I'd mention it as it might be more of an altitude/inclination thing than wind itself.

Re: APS question

If I take my son on a training ride with our Newton on his bike, is there any 'risk' that APS will pick up my sensors and switch profiles mid-ride?
Eg If I re-start from lights ahead of him?
Or does Newton need to get out-of-range of the 'old' profile before selecting a new one?

Re: Auto Shutoff

Perhaps also worth noting that even after auto shut off, when you manually turn back on the same ride will continue.
A new ride won't be triggered for something like four (?) hours of inactivity eg overnight.
You can always manually reset a new ride and/or split/combine files afterwards.

Re: Velocomputer

In physics power is defined as force x speed. Naturally, to do this calculation you've got to start the calculations at some defined point. In the Newton (and in all other devices for that matter) the ride file begins when motion or cadence is detected. So, if you're starting from a dead stop, in a...

It would suit me better if it did change the weight as I have my son set up as profiles 3 & 4 and he is half my weight.
So far I have not used the wrong profile for either of us.

Re: Display filtering time over intervals

You are on trainer or on the road? If you are on the road the Newton must be set to a user profile (I presume, to get the correct power) Not sure why it wouldn't get the display filter from there? If you simply haven't set it via your user profile then do it via 'set up' -> filter (set to 10 or more)
