Motorcycle TPMS Tire Pressure Monitoring System with 2 External Sensors LCD Display Motorbike Tyre Temperature Alarm

This is a no nonsense item on the bike, having a pressure readiut on the fly is great. The caps also unscrew and the batteries in the sensors can be replaced too.Instructions were lackluster, and the pairing process took a bit. But once done, it works.The handlebar mount supports 3/4 to 1 inch bars. My fat boy has 1 1/4 bars and it wont fit. I just keep the unit in the swingarm bag and check it when i hop on the bikeOverall, if this unit holds up by next riding season, ill be fitting it to all my family's bikes. Its a no brainer, cheap, and simple add on that may save your bacon one dayEDIT 7/22: This has held up excellently and continues to be reliable and reasonably accurate. My only complaint is no 1.25" bar support. If that was added, this would be a home run

Do not buy, it doesn’t work. Completely agree with Michael Jonhson’s review above. Since I started using it, the device shows the pressure of 44 psi for the front tire, and 47 psi for the rear tire; this is a high pressure for my Cruiser tires, so it is beeping all the time (it is annoying). It has been two months and the device is still showing THE SAME pressure. Tyre reading doesn’t change, even though I know for fact it has fluctuated several times. It is not accurate either. When it was reading 44/47, the pressure was actually 41/41, as it should be.There is no manual in the box to indicate how to reset it. I turn it off and back on and the same reading appears. Completely unreliable. A piece of trash; a waste if your money.

I tested the accuracy against my portable air pump and the two agreed. The display is clear and easy to read. The installation was a breeze. I installed on an ebike with 20 inch fat tires. The valve cap comes off, screw on the sensors, then they pair automatically.I tested the alarm but unscrewing one of the sensors and for about 30 seconds there's a beep beep beep alarm.The instructions are poorly translated but setup is simple if you've ever had a digitap watch. Press and hold the bottom button to get into setup, use up/down to select then change the value of each field. Super simple.Only thing I've found is the clock doesn't keep accurate time but I don't need the clock anyway. The point is the tire pressure (and temperature)

The TPM system seems to be accurate and has standard customization capabilities. Setting high and low pressure alarms, use bar or PSI units of pressure, set heat warning limits in Celsius and Fahrenheit, and has some other settings I can’t fully figure out due to the menu being borderline unusable. Once the setup is done the system works great!My main and only complaints are when accessing the menu to customize setting, the button to change numbers only goes one way making it so you have to cycle through the entire range of numbers until you get back to the number you’re trying to set it to if you miss the numbers you’re trying to get.The other main complaint I have correlates with the last thing I said but when cycling through number ranges, the device will kick you out of menu and go to the main display without changing any unconfirmed option which is really annoying especially with the high tire pressure starting at 40 by default which forces you to have to hit the number button about 50 times in order to set the high limit to 38. Setting the low isn’t much better but it starts at 22 and goes down to zero then back to 40 I’m pretty sure, so setting that one is just as annoying but easier since the number range is much smaller and leaves you less likely to get kicked from the menu before you’re able to set the number desired. But you have to set both the front and rear tire pressure, so the frustration really might get to you at some point.I’ve used plenty of TPM systems and this one by far has the worst UI but as long as it does its job precisely then that’s all that matters to me.Its average price makes me want to recommend some other system just because of the UI but this TPMS unit will do the job if this is your only option.It does not connect to your phone but that’s not why I bought it to begin with.It’s durable enough to ride with but I wouldn’t be rough with it since the terminal feels like a chinesium plastic shell.Really you can’t get much better than the traditional pressure tester every time you ride but if you’re lazy then this could save your life just the same.

This is the third one of these that I've purchased. First one works great on one with my bikes. I bought another for my other bike, and I'm unable to get it to work properly. I returned the first one because the rear tire indicator was flashing "0.0" and there was no instructions about what that means or what to do about it. The front one worked fine. I just installed it replacement system on the same bike, now I have exactly the same problem with the front tire, while the bear one is okay. It says to contact them for help, but I cannot find any contact information here or on there Amazon store. Amazon of course offers no help. I will turn this one I guess, but I just expect an excellent to have a problem also. At least the one on my first bike is working great so far.
