When I traded my 2 wheeler for a trike I lost the TMPS feature which I rely on to monitor my tire pressure. I asked Harley about it and they said the stock wheels won't work and suggested I buy 3 new wheels for a brand new trike! NO, of course, was my reply so I searched for a good set of TMPS to us and found these. Good reviews, I rate them GREAT, they work fine, easy to install and setup to monitor which now sticks to my dash with the strong 3M tape provided. Auto shut off when the bike isn't moving and good battery life on the monitor which also can be charged via the USB-C cable provided. Excellent way to save thousands of dollars for sure!!!

Initially beat, easy to install and the lock nut is nice so you don’t have to worry about someone taking them when you park your ride. Put them on my Ural sidecar and seemed ok for the first few weeks. My issue is more with the app. Rarely gave me accurate pressure readings even when turning the app on and off. Had the one with the readout been available I think it would have worked better, but many times I’d ride with the readout pressure being what appeared to be in range of my tire pressure only to get 20 min into my ride and see the pressure on the tires go red in the app (had my phone on a handlebar mount). After that happened twice I decided to verify the pressure before riding, regardless of what the tpms said. Defeated the purpose of buying this product. If you are on the fence, save your time. It’s not worth the cost.

I had purchased the tryke kit.one sensor stopped working totaly.about a week after.i replaced all the battery's with brand new energizer battery's didn't fix the problem.then the second sensor stripped out and would not tighten up.i have already permanently mounted the display screen to my bike.anfmd now I'm out 90.00 dollars.there customer service was not helpful at all.all I wanted was 2 new sensors to replace the bad ones.i would never recommend this company or there product to anyone.

These were installed and worked fine on my Harley tri-glide, but I neglected to use the lock nuts to keep the sensors in place. As a result, I lost my front wheel sensor in just a few weeks. I'm ordering another one since it was my oversight, and we'll tighten them up this time.

I ordered this item and is very pleased with how it works. It is very easy to install. It does take a little work and getting used to going through the settings. However, once you get it set, you are in the money. It's a whole piece of mind when I am out riding my Slingshot. I have only had to charge it once since I've had it and that was right out of the box. Battery life is superb as long as you turn it off at the end of the day after you are done riding. The only thing I had to do was replace one of the batteries out of the box because the transmitter wasn't recognizing my wheel. Once I replaced the battery; its been great. No Issues!!! Get this item with the mounted receiver. I have not tried the app so I do not have any tips or reviews for the app at this time.

There was some difficulty getting the sensors to pair accurately with my phone. I have a reverse trike; so figuring out which one was where took some time.The readings seem accurate, but I don't get any type of alarm from the app when pressure drops. I tested by removing one of the sensors causing it to go to zero. The app showed zero, but there was no alarm. It's great for checking pressure manually, but as for monitoring pressure automatically as you're driving, it doesn't work.

Day 1--Just received my three sensors and the SRTP-690 monitor. I'm doing the setup now before installing. Immediately discovered that all the settings for sensors 2 and 3 MUST be identical. Geez! So they designed this product to be used only on trikes and not on sidecars? I have three different sidecar rigs and NONE of them would I want the same parameters on sensors 2 and 3 (the rear tire and the sidecar tire.) But, frankly, I don't use a TPMS to get warnings about high or low pressure. I use them to get real time pressure readings as I ride. So once I get this mounted up and do some riding hopefully I'll remember to come back and finish this review. Two stars for now (not one) because the setup procedure is fairly easy compared to other 3-wheel TPM systems I've used.Two days later--went for a ride. The RF transmitters in the sensors are motion activated so there's no reading when you first turn on the head unit. Four minutes into my ride Sensors #1 and #2 were sending pressure readings and the readings were pretty accurate (checked against a Longacre Racing gauge). Sensor #3--nothing. Rode for 30 minutes and got no readings from #3. Gonna order some new CR1225 batteries from Amazon (10 for $6), install one in Sensor #3 then go riding again to see if that was the problem. Otherwise, I'll be contacting Sykik about a new #3 sensor.Speaking of batteries, the head unit does not have an auto shut off so you have to remember to manually turn it off when you finish your ride. If you forget, no big deal, it recharges using an ordinary micro-USB. I'm not going to tell you how to mount the head unit--that'll be different for different bikes--but I'm using a 1" Ram ball with a built-in 1/4" camera mount. The 1/4" camera mount screws directly into the back of the SYKIK monitor, then I mounted the Ram ball to my bike using standard Ram accessories.More to come.Six-days later -- OK, batteries came from Amazon, really easy to install as long as you didn't throw away the round wrench that comes with the kit. Use a fingernail to pry off the bottom ring, then use the wrench to unscrew the waterproof covering on the sensor. Push out the old battery and push in the new one, use the round wrench to screw the cover back on, and snap the bottom ring into place Takes about 3 minutes?Mounted my balky Sensor #3 on the sidecar wheel, put on my gear, turned on the monitor, then rolled my sidecar rig out of the garage. Wow--already getting an accurate reading from Sensor #3! So fresh batteries clearly makes a difference. Within one minute I had a reading from the front wheel, and the rear wheel kicked in about 2 minutes later. And I was still in my neighborhood so hadn't gone over 25 MPH yet. Went for about an hour ride and the system worked great. Pressures went up about 10% as the tires heated up -- totally normal and expected -- then when I stopped for gas the pressures dropped down (ambient temp in the 40's). Successful test ride! Finally feel OK peeling off the protective plastic off the face of the monitor.Bumping up my rating to 4 stars. My suggestion is if you plan to order this system, go ahead and order a strip of CR1225 batteries at the same time and install them before you mount the sensors. Also, hopefully this goes without saying, make sure you have rigid metal valve stems at all three corners of your rig. That's true for any TPMS that uses external sensors.
