MACUNIN Bike Computer Multi Function Wireless Waterproof Bike Speedometer Odometer Cycling Accessories with 3'' Large LCD Display and Backlight

Took the plunge and bought this computer. I have used many much more expesive ones but was intrigued by the huge display. So far, set up was relatively easy. Merely a bit of confusion with knowing what was being referenced on a few things during setup, as it was not mentioned in the directions, but I got it sorted out. Converted to MPH easily. Has preset tire sizes. The product description is good. Crazy list functions. All I really care about is MPH, time and Distance/Odometer. Odometer and MPH readings seems pretty accurate and line up with my other computers and people I ride with. Best thing is the display. It is huge. It is really nice being able to see my speed so large on the screen. Scrolling is pretty easy, even with all it's functions, and whatever function you're set on displays pretty large on the screen too. The backlight is really nice and easy to turn on AND off. Nice and bright. I did unfortunately get the oportunity to ride with it in the rain and it held up well. The mounts it comes with are a huge plus. I use the clamp on mount and it is rock solid. My similar Cateye Pardonne with mount cost me three time as much as this and has a smaller display. Reviews are sketchy as ... with regards to the reliability of computers so I took a chance on this one. If it lasts a year or more, which I believe it will, I'll be content. It is a nice unit and I plan to buy another for my other bike.

From the time I opened the box to taking a test ride, it took less than 30 minutes to install and program. Simple to operation and easy to read. I would be hard pressed to find a better device in that price range. Highly recommended.

quick review here as it hasn't been mounted on bike yet. So far it seems to be a nice unit. A couple things to note; first thing everyone wants to do is set the clock.. at least I did. But when you enter the computer mode to set wheel circumference etc, that resets everything including the clock.. so just set it up in order per the instructions. It's got a ton of stuff on it.. you can enter your age, weight. It has temp.. all modes can cycle thru with the mode button and that will be the bottom display.. the big top display is always your speed. But when it's on Scan mode it automatically cycles thru just 4 modes, Distance, max spd, avg spd, timer, with speed still showing on top.. which is great. Speed can be in kmh or mph, clock can be 24 or 12 and backlight can be off, on for a few seconds or on permanently.My second note is this.. it comes with 2 brackets. 1 has a curved mount that can afix to a handlebar or tube with zip ties, the other bracket you attach to the extention that then fits around your handlebar.. once this bracket is attached to the extention, it doesn't come off.. so if your sitting at your kitchen island looking at all the parts, seeing how things fit together, don't attach these 2 pieces because they are made to not come apart. I had to use a small screwdriver to separate them. The computer itself stays solid in either mounting bracket and had a quick thumb release. It turns on and off by itself.. no power button. I manually waved the magnet over the transmitter several times with my hand and the computer woke up and turned on and began to register mph..!More to come after installation and use..on a ride right now.. trail is marked with mile markers..and confirmed with 2 years of consistant readings on MapMyRide GPS.. and I mean consistant down to the same bump in the road every time.. I have correct tire setting for a 700x32tire according to their manual. It started by registeringing a mile AFTER I passed the marker.. not by much but by maybe 5 seconds which doesn't seem like much but at 15mph is a concern.. then the 2nd mile.. another 5 seconds off so now I'm around 10 seconds passed the marker.. so I'm thinking I input the wrong numbers or something.. then I remembered I just changed my tires from a 700x35 to a 700x32..sweet..that must have been the issue... nope.. tried it again today with the new values.. just as bad. It was off a half mile in a 2 1/2 mile stretch.. I ACTUALLY WATCHED IT JUMP FROM 1.4 to 1.8 MILES IN JUST ONE READING. .. that's almost a half mile in one change of the readout.. no way a change in tire circumference is going to fix this $25 piece of junk.. Returning it tomorrow..just got back from Kohls.. it's headed back to wherever the hell it came from..

I like this little bike computer. The display is a good size and the speedometer is always easy to see.The additional parts like the mounts are not the best.Pros:display is easy to see - great size, clear view, really like being able to check at a glance big numbersmany options and seems fairly accurateeasy set up using the wheel chart for diameterinexpensivewirelessCons:if you want to see more than just 2 lines of data - i.e. speed and odometer plus elapsed ride time, that is not possible without scrolling. There is a rolling option however.My only real complaint is the quality of the mounts. They are not terrible but they aren't great.The main bar mount clamp is too wide even with the included rubber tape so I had to improvise a bit to add another piece of rubber around the bar. No big deal.The way the computer clips into the mount - it's easy to think it is fully clipped in when it is not. It does not lock into place on its own when you push it into place. At least on both brackets I received, you need to forcefully press up on the latch to properly secure it and ensure it does not come off the mount.The mount for the transmitter - easy to mount using zip ties and uses a piece of rubber tape between it and the fork. However the tightening screw for it which allows the receiver to swing back and forth for positioning really does not tighten up fully. It's still easy to move the receiver which could cause it to accidentally be moved too close to the wheel. These are all plastic parts so trying to over tighten something like this would probably break it.***Overall - for the cost and design of this bike computer I'd definitely recommend it and would purchase it again. Improving the quality of the mounts is really the only area I took off for in the star rating.

Nice big numbers,easy to set up,very happy
