yea, but how does tightening a little nut up against the sensor from behind stop the sensor from just unscrewing right off the valve stem?AFAIK, they were supposed to secure the cap so it doesn't come off and no one can steal them.

Yes. It's mentioned in the FOBO manual and short metal valves come with the kit. While I'm not recommending it I've run the caps on the rubber stems fro a few thousand miles with no problems. The bike is garaged and isn't exposed to the elements unless being ridden so the stems are in very good shape.I'm assuming metal valve stems are recommended?
The nut is a "jam nut". By screwing the nut tight against the cap they immobilize each other. The component threads are plastic so they can't be tightened too much. And they could probably still be removed with a good twist. But it does provide some security.yea, but how does tightening a little nut up against the sensor from behind stop the sensor from just unscrewing right off the valve stem?
If you never compare it against anything how do you know that you can trust it.I figure if I can trust it while riding, I can trust it while filling.
I’ve decided to do these stems, now just narrowing down a system.HawksHead sensors on KurveyGirl 83 degree 11.3mm Bridgeport (Ariete) Valve stems here, for many years.
Do you have to drive a bit before they’ll show the pressure amount? I’d much prefer to be able to see the amount before riding any.I use the Sykik 300…I have them on all 3 bikes- I have had to replace a couple of the monitor units over the years but you can buy just the monitor for $28 (well, that’s what it was when I last bought one) and didn’t have to swap out the tire sensors. I didn’t want a phone related one as I normally don’t have my phone in a dash holder. I agree to swap to metal tire stems (I have the 88 degree type that are solidly mounted to the wheel- I think Kurvey Gurl brand which are essentially the same as the Ariete valves).
Do these have to be moving to get a reading?HawksHead sensors on KurveyGirl 83 degree 11.3mm Bridgeport (Ariete) Valve stems here, for many years.
It seems to vary quite a bit, but yes.Do these have to be moving to get a reading?
A little bit, like a 100 feet or so, but I always manually check the tire pressure before a ride and the Sykik is more to monitor the pressure when on the road.Do you have to drive a bit before they’ll show the pressure amount? I’d much prefer to be able to see the amount before riding any.
Thank you. I’ll check this out. I’d really like to be able to see the pressures without having to start riding AND have a way to monitor them while riding in case of a leak, and I don’t attach my phone to the bike while riding so I can’t use that. The Florida sun will kill a phone quickly if exposed. But, the main thing I’d like is my first point above so the Fobo 2 may be the one that I get.Here's the best video review of the FOBO 2 I've seen so far:
TIL: FOBO has an app or the FOBO app can be downloaded to CarPlay and be seen on the Honda GoldWing "dash" while in motion. It wasn't mentioned the review but I would think it could be installed on most any vehicle's CarPlay.
The Florida sun will kill a phone quickly if exposed.
Shoot, I never thought about that! I have my phone connected to my Cardo so I would assume I would hear the alert via Bluetooth. That might seal the deal for me.CA sun can do the same. I cover the phone if the sun is overhead or behind me. But I also have a Sena 20 connected to my phone (via Bluetooth) and get an audible alert with the pressure is above or below the limits set. If it's a blowout no TMPS is needed.
This allows me enough time to pull over and see what's what if my phone is in my pocket. I realize a Hawkshead style TPMS would provide constant monitoring but it's a compromise I'm ok with.
If I was considering a 'Wing the FOBO and CarPlay would seal the deal. LOL
The sensor will not unscrew from vibration with a jam nut, but said j-n will not prevent theft.yea, but how does tightening a little nut up against the sensor from behind stop the sensor from just unscrewing right off the valve stem?
Most of the TPMS sensors turn off after a period of time with no motion. This saves and extents battery life. My FOBO and Hawkshead units have different turn on times - with the latter coming to life with less motion. Both were active by the time I wheeled my bike out of my garage.Do these have to be moving to get a reading?
It's a paranoid world we live in.The sensor will not unscrew from vibration with a jam nut, but said j-n will not prevent theft.
Excellent solution. I've used these for the past 10 years, so convenient.FOBO 2 user here, bought off amazon a few years back and about 60k miles ago. I’m sure there as good as all the others. Down side is they work after wheel rotation starts, sometimes before. They go to sleep and wake upon movement. One battery swap in that time. It is phone app based, I’m using IOS and it has been fine save the ask for location services. No, you don’t need to know where I am.
They do a decent job, PSI is close to any of my gauges, and seeing while riding takes away any anxiety about pressure. Having a temperature check is nice too.
I’m fixated on brakes and tires for vehicles. I would love the a/c to work, but need to stop in the rain. Point being I don’t try to save money on those areas. I recommend “T” valves, put the sensor on top and air up from the side. Cheap comfy stuff is great, but your life depends on these bits.
