Sun Company Clip-on Bike Thermometer | Bicycle Handlebar Temperature Gauge and Cycling Accessory | Rugged Handle Bar Thermometer for Bikes, Motorcycle, ATV, or Snowmobile

Work great and tells the outside temperature as I am mowing my lawn. Seems to hold up well in freezing temperatures as well. Probably filled with glycerin, which helps dampen the movement of the needle. No batteries required to make this work. Fits well on the handlebar on my walk behind mower. Simple to install, just add the rubber and slip it over the bar.

Constantly shows 80 degrees. Then today showed 110 degrees. For reference it was 74 out today. This thing DOES NOT work.

I put this on an old Ducati Monster motorcycle handlebar. Fits well with the provided reducer rubber straps. The thing works and doesn't require power, so that's nice. But, as others have mentioned, the print is really, really small. Pretty much unreadable while riding.

I've had this for a few weeks now, and it never changes from 80 degrees. I'm starting to wonder if there's something I need to do to activate it, like when you take off a cover to start the batteries in a TV remote. Right now in my area, it's been about 40 - 50 degrees, and even sooner, it will be lower, but it still doesn't change from 80. I've double checked the weather app and everything. It is too unreliable for me.

This is a great little thermometer for a motorcycle. It fit snugly on 7/8" (22mm) handlebar tube with the rubber ring underneath. Just take your time and snap it on slowly so you don't crack the plastic.Some people have complained about accuracy. It is all about use case - I just want to know how warm/cold it is to the nearest 5 degrees F, and for this job the thermometer is great. Yes, I have to look closely to read it, but this is not a big problem. I don't need to read it while riding. I mounted it up by the throttle grip so it is easier to see.A few people have commented about accuracy. The one I got seems to read about 2-3 degrees above what another digital thermometer shows, and I am happy with this. Different units probably vary slightly. The up side is that this is small, discrete, and there is no coin cell battery that needs to be replaced.My only complaint is the temperature range: -20 to 120 F is a ridiculously huge range. My guess is very few people bike below freezing (32 F) or much about 100 F. A dial with a smaller range would be more accurate and easier to read. But perhaps this is just the range you can get with this particular bimetallic-strip type dial.

Unfortunately, this thermometer is so slow to respond to temp change, one would wonder if it's working.It does fit nicely on my bike handle bar.I did remove it because it functions so poorly.I bought this for bike trips to monitor temperature. I would not recommend buying it because it can't be returned.

Clips on to handlebar in seconds. Fairly easy to read with good eye sight but it is only the size of a nickle so looking at it you could be a degree or two off, but it will get you in the "ball park". Accuracy seems okay. When you are sitting and the sun beats straight down on it, it does seem to read high. I believe I get a better reading when I am peddling the bike or am out of the sun. I have enjoyed mine and feel it was worth the money.

WOW, I don’t know where to start. I read the reviews and most of them said it’s very small. The unit is very small and hard to read, well all of them are correct. I cannot believe how small this temperature gauge is I’ve sent a picture along with my review, showing how small, this item really is! They must have a great camera on a macro setting to take pictures that make it look big! So I am suggesting unless you’re a child under 10 years old don’t bother buying this product it’s just going to piss you off, oh by the way, you can’t return it so you’re out a pocket 13 bucks! Buyer beware!!!
