leepee Motorcycle Tire Pressure Monitoring System, Tire Pressure and Temperature Alarm, Wireless Motorcycle TPMS with 2 External Sensors, Support iOS and Android, Valves for Vehicle Tires

I am incredibly pleased with this product; it’s working flawlessly. I ride with my AirPods and set it up for voice alerts since I don't have my phone mounted on the bars. I have angled valve stems with limited clearance, so I wasn't sure these would fit. They do and with plenty of room. I compared the readings with my quality digital gauge; they are spot on. I tested them by unscrewing them until the air started leaking; the app alerted me nearly instantly. I sent LeePee customer service a message before ordering; they were very responsive and helpful. Great product backed by excellent customer service. Also, be sure to use the provided anti-theft nut. It serves as a theft deterrent and keeps them from coming loose while riding. Not that they would be good to anyone who stole them, more so to keep someone from screwing with them. Be sure to keep the provided wrench on the road if you need to adjust your pressures.Overall, I'm highly impressed and pleased with this purchase and their customer service. It's not often that I can't find anything to complain about; this is one of those times.I highly recommend this product to any motorcyclist. Tire pressures are often overlooked and/or forgotten about—very inexpensive piece of mind. Even if you check your pressures regularly, this will help identify a leak out on the road that could save your life.Excellent product!

I rarely leave reviews unless I feel a product really deserves it, and I like this one. Not a paid actor, genuine customer. It works well, it’s simple to use, it does its job well. Is it flawless, absolutely not - the app is a very basic Chinese translated style GUI, but for the price, it is very well worth it. 10/10. Monitors air pressure and temperature very accurately, it’s hardly bigger than a normal valve cap, and it couldn’t be a simpler install. Even if this pair of mine broke in a month, which I don’t expect will happen because they appear to be well made, I’d still just buy another pair. Love ‘em.

I like the price, less than the competition. I have TPMS experience with factory systems on two cars. However I purchased for my motorcycle. Possible negatives? I say possible because it may not be an issue for you:1) They are kind of chunky, about 20mm Dis x 20mm high. I had no problem fitting them but due to my double front disks access to the valve stem is limited with or without TMPS. They fit my bike fine, just be aware.2) I had issues getting it to work. That may be me. It took some fiddling and double checking.I don't know when the valve stem TPMS monitors transmit. Some complain they don't update. I do know if you remove them with your phone app connected you get a warning Front or Rear Tire Pressure Too low warning. If pressure does not change it could be movement that triggers them. However I doubt they transmit all the time when riding. That is typical to save battery. People have complaints it does not update enough. I find it does update. I check it from time to time when in garage. I know it has changed as TEMP changes and PRESS changes.You get Battery percentage and voltage. I have had them on about 3 weeks with limited riding and they are at 94%. I can not tell you what they read out the box. I suspect you will get good live. The battery is a cheap coin battery. I do know when I take them off to add air, the reading changes to what pressure I set them to (with tire pressure gauge) after reinstalling.Accuracy could be 0.2PSI or 0.5psi plus minus. This does not account for how accurate my Tire Gauges are. I have two or three so I know they all read close but not the same.Positives;As mentioned price, significantly less than the competition. Are they as good? Don't know. Also these are first ADD ON TPMS I have bought. I don't always ride around with phone on and app running. People have complaints it does not update real time? What I am fairly sure off is you lose pressure while riding the TPMS will signal that real time. With a motorcycle you know when pressure is significantly low.Are they worth it? Yes I am glad I bought them. Do a NEED NEED them? No I could get on the garage floor with tire pressure gauge and my air chuck and check and trim the air pressure. No TPMS NEEDED. However it is nice. I have another application on an experimental plane with wheel pants. It is a huge pain to get the wheel pants (wheel fairing) off, to check air pressure. With pants on not only can you not get to tire valve stem, you can't see the tire, the tiny bit on the ground sticking past the wheel pants. BTW eye ball pressure check is totally useless, only way to do it properly is with air pressure gauge.4 Stars based on instructions, my difficulty (could have been me) getting it to initially connect. I'd give it 4.5 if I could. I did do a few things I read on internet that may have got it to work, but that should be in manual. Needless to say the instructions are not great. However the product works. Last based on rumor's. It does ask for GPS location. This could be to trigger the TPMS to do an update, so it knows the vehicale is moving. People claim it is spyware. I see no sign of that. However I am no expert. I am using a Samsung Android powered phone.

I'll start out with, the sensors do seem to measure air pressure accurately.The app does allow you to set upper and lower bounds for air pressure before it sounds an alert.When it does give you an alert, a female voice with a mandarin accent comes on to repeat the warning over and over. But that's where the compliments of the app end. This is definitely a quickly thrown together, poor quality app.The biggest issue is that there is no indication if you are actually connected and giving you the latest air pressures. When you open it, there's data already populated from the last time you used it. But you have no idea if those tire pressures are current or not. I've made a habit of opening the app as soon as I get to the garage, and then checking it as the last thing before I roll out, hoping that I have the latest data on the screen.In hindsight, I wish I would have gone with a TPMS system that has a display mounted on the handlebar.

I was going return these because of other reviews of valve stem and tire damage. I tried them on my 2002 Honda VTX1800R and they work great. Shows pressure and temp. I rode about 14-15 miles with them and they show real time info. I set my cold pressure at 40psi and it alerted me that my pressure was too high at 43psi, which I set. I lowered my pressure to 40 psi warmed tires. And cold shows 38 psi. When you 1st open the app you will have to give it second to update pressure and temperature. Seems to work great, though.

Brilliant low cost mod. I don’t know why every bike doesn’t come with this. Valve stems are hard to get to on my heavy bikes … MUCH better to monitor pressures & temps on my phone and only add air when needed instead of laying under the bikes once a month. Easy to install and set up the app. Very happy!
