SPGOOD Wireless Bike Computer 16 Functions Waterproof LCD Speedometer for Bike Speedometer

This bike computer does exactly what I wanted and lives up to the description and reviews left by others. It had clear, easy to follow fitting instructions with photos and diagrams to aid installation. The computer acts like both a car's speed and mileometer combined. It gives a clear readout and acts as an encouragement to maintain and ultimately increase your average/maximum speed and overall journey time as your fitness / cycling ability improves. I find it more accurate that Google Maps for tracking my journey's exact distance and am happy that I don't have to sign up to a phone app to monitor my movements. The bonus feature I really like on this computer is the cool, green backlight that illuminates the display during the dark evening/night/early morning hours. All in all, I'm really glad I chose this bike computer and can definitely recommend it to others.

I installed this on my second bike that I keep on turbo-trainer, it was to give an indication of distance / speed I'm training at when the weather is poor. I think this kit is adequate for that but watching the readings it does seem to jump around quite a bit - the instant speed drops and then picks up again within a rotation and even the average speed reading seems to jump around which is odd once you've done several K. The sensor and display unit also need to be pretty close to each other. I mounted the sensor on the rear wheel (obviously) and it wouldn't pick up from the handlebars. The instructions say 60cm but you expect that to be conservative, I don't think it is. Overall works for me at this price but I wouldn't be putting it on my main bike and relying on it.

There are three great things about this wireless cycling computer. First. No more wires tangling up the front fork, brake cables and the like. The radio transmission of each wheel revolution - captured by a neat sensor on the fork and magnet on a spoke - works just as well as my previous wired device. Second. It's waterproof and keeps going even during heavy rain - unlike my previous wired computer that invariably packed up with just a little moisture in the air. Third. It's easy to set up with good instructions as to how to calibrate the computer for the particular wheel/tyre size of your bike. In addition, though it goes to sleep after a long stop - so needing to be awakened manually on setting off again - it stays live long enough for a short 'nature break'!

The sensor doesn't always recognise that my bike is moving, so it won't record my speed or distance travelled. It's good when it works, but I guess, you get what you pay for.

I bought this to have some feedback when cycling at home with my bike on a stand, as I am not moving all my GPS kit doesn't work, but having experimented with multiple fixings this device only gets a reading if there is less than 3mm between the magnet and the sensor, so you cannot install it as instructed, the sensor has to be inside the fork practically touching the spokes & magnet, which I would not like when cycling outside. also this will not work on the rear wheel as the bike computer cannot get a signal from the sensor at at that distance! OK it was cheap, but you would hope for better performance than this.

Bought this for my son's bike. Good no-nonsense bike computer. A breeze to install, it helped that I already had a similar one on my own bike. I like that the actual computer can be mounted in any orientation in its holder, so it can be installed either on the handlebar or at 90 degrees on the stem. The light-up screen is a nice touch (light only turns on during evening hours, so do set the time) Was a great excuse for discussing basic physics concepts with my son, like relationship between distance/speed, magnets, wireless transmission. "It can tell how fast the wheel spins, but how does it KNOW how big the wheel is??" "MAGIC." Would have liked a temperature sensor. Doesn't come out of standby mode on its own, you need to remember to click a button when you start your ride.

The bicycle computer has pretty much all the fiunctions you need and the sensor pickes up better and more reliably than my old one. Instructions can be a bit complex at first but if you use it regularly you soon pick the idea up. The only comment I would make negatively is that the display is not easy to see in poor light and the backlight only works for a few seconds after pressing the button. I think there should be a switch of somekind which illumninates the screen permenantly, if you wished it to be or weanted to use it at night, although that would obviously run the battery down faster. Overall fairly pleased for the price.
