Customer Reviews:

  • Great with two minor complaints
    This is my third cycle computer, and there's quite a bit I like about it; first, it looks cool and is relatively compact. It has every feature I would want, and so far doesn't seem to interfere with my chest-mounted heart rate monitor. This is easily the best fork-mounted wireless sensor available (compared to Sigma and Blackburn), as it's small and solid. It's relatively easy to use, the backlight feature is helpful at dusk.

    Now the complaints: The instructions are the worst I have ever seen on any product I have ever purchased. Cateye should be ashamed of themselves, and if you decided not to purchase this for this reason alone, I wouldn't blame you. also, the plastic tie system for adhering the computer to the stem or handlebars is cheap, and doesn't cinch tightly....more info
  • Cyclocomputer
    The computer works good at keeping tract of your speed and distance. The amount of time it took to get it was very short. I think that the owner's manule could be a little more straight forword, and the instructions on how to navigate through the different settings should be more clearer to read. Other than that, the product is well worth the money....more info
  • Cateye Micro Wireless
    I looked at many computers before selecting this one. My neighbor recommended it over the computers he currently has on his bikes. He plans on getting two new Cateye computers soon. Installation was very easy, and I haven't had any problems at all. It is very accurate. For the price, I really don't think you can find a better computer. I highly recommend it....more info
  • Works Great
    I've only had the bicycle computer for a couple of weeks, but although the installation instructions are kind of vague, the computer works well. It mounts with double sided tape and cable ties, so it tends to move around instead of being clamped solidly to the handle bar. ...more info
  • Once it's on, it's great
    Clear display, easy to use. Installing the transmitter was too tricky for something so simple. Instruction sheet was not helpful. Good value for $30....more info
  • Initial Pain to Setup
    I read the reviews and saw the complaints about the instructions but told myself, how bad can they be? Well, I wouldn't call them instructions at all. My biggest problem was setting up the sensor and the magnet. The pictures were were not any better. It's finally working I think and hope the pain is over from this point. A friend of mine got one by Sigma and he was happy with it....more info
  • LCD Failed after 6 months
    I guess you probably know by now that the instruction manual sucks. I'm typically not much of an instruction manual guy. I'd rather figure it out by pressing the buttons, but there's no way a human could figure out how to program it (e.g. setting your tire size, clock etc.) without resorting to the manual. So if you do buy this product, you may wish to tape the manual to the inside of your helmet. Then, as has been stated in many other reviews, get your Manualeese to English dictionary ready.

    Installation was not difficult, except that once you choose a location, you're stuck with the results. Unless you can find some long skinny zip-ties, once mounted there's no going back without cutting the ties that came with it. Replacements are not easy to find as the zip-ties are an unusual size (long for their gauge). I made the mistake of mounting it to the handlebar stem instead of the handlebar itself (you can mount it either way). Having it on the handlebar itself allows you to rotate it slightly to get better contrast from the screen.

    The unit was working fine for about 6 months or 100 miles (whichever came first?). After a few weekend rides the tire size indicator (A) started flashing. I just ignored it. Apparently this is the Manualese signal that your battery is about to die. Once fully dead I replaced the battery and all seemed fine. I dug up the manual and figured out how to set the clock and tire size (and learned why it was flashing in the first place) and input a guesstimated ODO setting. Unfortunately you have to remember your ODO setting as it forgets when the battery is removed (how much extra would it have cost them to throw in a couple bytes of NVRAM for the ODO?). So how many miles it actually survived I can not say because by the time I had a replacement battery the old one was totally dead and I could no longer read it. It had around 100 miles on it

    Next week I take the bike out and the LCD display looks very dim, but all the functions seem fine - you just have to look at the LCD from a strange angle. I dug up the manual to look for an LCD contrast setting, but it does not exist. So I figure the replacement battery might have been defective. I go out and by another CR2023, replace it, and no luck, the screen is still very dull and hard to read.

    So all in all I'd say this unit performs well when it works (maybe I just got a lemon). But they could really use some improvements in the user interface/manual.

  • Perfect Cateye
    This wireless cateye is just what i was looking for! The backlight is great when you are riding at night!...more info
  • Cateye CC-MC100W - 5 Stars!
    The MC100W is the first bicycle computer that I've ever used and so far I'm very happy with it. The instructions are NOT that difficult to understand as some earlier reviews suggest. I'm basically an idiot and I had it set up, installed, and tested within a half hour. It's fairly accurate, easy to read/see, and the backlight works fine. I have it strapped to a Specialized Rockhopper that I use for daily street rides and some light XC on the weekends. The Cateye CC-MC100W is a good product at a fair price....more info
  • Mounting system is not good but the computer is great!
    The computer is great, it has a lot of functions and features and the wireless works very well. The only thing I was dissapointed was the mounting system, it is with nylon ties while the Strada Wireless has the "FlexiTight" Bracket Mount which has a faster installation. Besides if I need to switch it to another bike is faster and I don't need to have spare nylon ties with me....more info
  • Inexpensive way to calculate speed, time, and distance.
    I wanted a way to compute speed, time, and distance, but didn't want to spend to much since I wasn't sure if the information would be useful. I'm not training for anything. I mostly do 1 hour mountain bike rides and short rides to campus. I was just curious how far I went. This simple bike computer does the trick.

    The instructions are a little scary looking, but not too difficult to follow. Just read carefully first. I was up and running in about 30 minutes. The computer itself is simple to use. The MPH is the big number, and I keep mileage on the the small number. Once I'm done riding, I note the numbers and I'm done. It's nothing fancy, but a good place to start if you don't want to spend too much up front. I may upgrade to a bike computer that can store and upload info to my laptop later, but for now, this one works. ...more info
  • Great Computer for your bike!
    This thing is great. Wish I had one when I was a kid. We had the old school speedometers back then. Now the computers supply all the data about your ride you could want. easy to install, simple to program. You will not be disapointed....more info
  • Easy to install, works great
    I bought two and they both work perfectly. I just used the included tie straps to put the sensor on the front works and then attached the receiver to the handlebars, set the diameter of the wheel (just the number on the rim) and everything just worked. Very cool....more info
  • Great Features
    The computer is a great tool to use when you are riding. It has kept me more motivated since I can set goals for myself based on my previous performance according to the computer. This item works great every time....more info
  • manual start/stop feature a plus
    The manual start/stop is the most important feature to me. It's the only way to save all my data at the end of a ride while I'm still on the bike cooling down. Most computers are exclusively auto start/stop, other than the bottom end generic ones that only have manual start/stop or the very expensive ones that have both auto and manual. The only con I have is it could be a little brighter display. ...more info
  • great computer, lousy mount
    First off, this thing works great. It was easy to install, a snap to get going, and it does everything advertised.

    The problem is that Cateye has paired this great computer with a really poorly designed clip that attaches to your bike's handlebar. After only a week of riding with it, the little tab that releases the computer body broke off. It is a small tab that is connected to the rest of the holder with only 2 tiny slivers of plastic. After a ride I punched it down and it popped off. The result is that the next time I went riding the computer flew off somewhere out there. Fix the holder and it would be great....more info
  • Difficult to operate
    This is a reliable, nice, bike computer BUT the instructions are incomprehensible. CatEye should be ashamed as they have made bike computers for like 20 yrs.

    Their website is sleazy as well as I gave a fair review of the product and they then removed my review from their site after one week.

    A good product that is difficult to operate. My friends totally corroborate my conclusions....more info
  • Nice features for the price.
    Installation and usage was a snap. I really like the size, position and read-out. My complaint is the timer/counter keeps stopping during my rides. I am not hitting the stop button or any buttons, yet it always halts during my last 3 rides. It may be from hitting bumps in the road, not sure. I am frustrated by this problem and hope I can solve the issue soon....more info
  • Easy Installation and Great Features
    Many have complained that the instructions for the Cateye Micro Wireless aren't good. This may be true. However, the installation is so easy that it seems like complaining about a milk bottle not telling the user how to pour it. Granted, if you've never installed a cycle computer, this may be an over-simplification of the situation. However, for the most part, the diagrams show you what you need to do.

    As far as the performance of the unit, I have logged over one hundred miles in the last few weeks and it has performed flawlessly.

    It's small, VERY LEGIBLE, and appears to be accurate. I highly recommend it and hope that you all will be as pleased as I am....more info
  • Easy to install
    I purchased two of these for my parents and had them installed and working in about 15 minutes. It has the features we needed and a breeze to install being they are wireless....more info
  • Very Poor Wireless Range
    Item description says it can reach up to 70CM away from the sensor... well this is not the case at all! Even with a fresh battery, I was only able to reach about 20CM which was not nearly long enough to put on my front wheel.
    ...more info
  • Easy to use, comes with everything you need
    first thing, it comes with all the zip ties you would need to mount it. also comes with all the mounting hardware you need.
    2 sets of data, so if you accidentally reset one of them, you still have another set, or if you're comparing 2 sessions of record.
    very informative instruction and easy to understand with diagrams....more info
  • Great! Very Accurate, Easy to Use! Highly Reccommend!!
    This bicycle computer is the best on I have ever purchased, and the most accurate. The instructions are easy to understand and installation was quick and effortless.
    When I first installed this computer the speedometer readings were so different from my last speedometer, I tested its accuracy against my friend's Prius. Turns out, this is the most accurate by far!!
    Can't recommend enough....more info
  • Great Product
    Easy to install and very accurate. I first drove a stretch of 10 miles and then rode it on my bike and it was right on. I would definitely recommend this to a friend....more info
  • This is a fine product
    This product is pretty good for the price. I use it as a secondary unit to track the time and miles I put on my trainer. It has worked fine so far. You need to keep in mind that the rage of the unit is limited. you cannot mount the device on the handle bars and the sensor to the back wheel. That distance is too large for it to sense. I placed the unit between the handle bars and the seat. It works fine there. I usually take it off when I go out to ride. It has a lot of functions too, which I ofcourse do not use. ...more info
  • Initial review
    Cateye delivered as promised with Super-Saver shipping. Product in-tact with no concerns.

    Instructions may be a bit confusing for some, but pretty straight forward. Can't figure out for the life of me why 5mm is the max. distance between sensor magnet and sensor zone. For my Trek 4500 this seems too close for comfort while riding the trails. I'll be watching closely during my first ride to see if this thing slips from position. With zip ties I don't think the computer or fork sensor will fall off yet the spoke magnet.... we'll see.

    I bought this Cateye because of so many positive reviews. With so many positive comments, I don't feel this will be a waste of my heart earned cash.

    ... to be continued. ...more info
  • OK for the first year.... then forget it
    I bought this 2 years ago. Getting it to work right was a little difficult, but I eventually succeeded. What worked for me was to put the transmitter on the front part of the fork, not the rear. For some reason, I got no signal at all if the transmitter was mounted to the rear of the fork, but it worked fine in front. It seemed finicky to me, but at least I got it to work.

    This spring, I replaced all the batteries - in the transmitter and the head unit. Then I went on a ride. It worked fine for 20 minutes, then the display went to 0.0 mph. Then it came on. Then it went off. I replaced the batteries again (checked them with a voltmeter first to make sure they were good) and same thing. Very erratic. I contacted Cateye Tech support (email only these days - even the phone # tells you to email them) and got no response. Twice.

    I'd like a little more reliable unit. And with no Tech Support to speak of, I can't recommend any Cateye products.
