Wireless Bicycle Computer with 1.4-inch Display

Pros: Cheap.
Wireless.
Lot of functions.
Good build quality.
Batteries are easy to find.
Easy to install and configure.

Cons: Rattle snake :)
Te main unit has some kind of motion detector (small pipe with a metal ball inside), which is used to automatically turn on the computer.
And it constantly rattles when you ride!
Not too loud, but annoying.

Other: Good, but requires some modification (not necessary).

Pros: -Really good for the price
-Shows speed, distance and you can change it to miles or kilometes whichever you prefer.
-You can set your circumference of your wheel to calculate proper distance.
-It has times, time of trip and a proper odometer with overall distance or trip distance just like a car :).

Cons: -If you lose some parts its over, you got to buy a new one.
-Very diffuclt to set up but that may be just me because I suck at instructions.

Other: Overall awesome item! Wish it were more simpler though than it would be good.

Pros: It's cheaper.

Cons: Isn't waterproof. That works in the rain, but after, the display condenses the water that was infiltrate. Don't work properly with Magicshine bike light. The PWM frequency confuses the bicycle computer that shows around 40 km/h, but without count distance. -- Não é a prova de água apesar de funcionar sob chuva. Apenas depois a tela ficará embassada por algum tempo. Com os faróis Magicshine ele não funciona! Marca cerca de 40 km/h sem registrar distância.

Other: Buy only for your child to have one like yours. -- Compre apenas para o seu filho parar de pedir um igual ao seu!

Pros: It was cheap easy to set up (except auto) easy to install

Cons: It goes bannans when I turn on my headlamp. Its OK on full beam but low beam and flashing it does crazy stuff. It rattles, not just the motion sensor but the mount is two parts and they rattle too, even without the computer attached. It doesn't have a stopwatch, the most basic of all functions. It claims you can have "Auto" On/Off but there is no way to turn Auto off and so I can't even use the trip timer as a stop watch (My priority is to measure elapsed time and you can't do that. You can only measure Trip (moving) time. Ideally I'd like to do both). it has no backlight and you can't read it at night unless you wear a headlamp (on your head) (and then it doesn't work anyway) It loses the odometer reading when you reset or replace the battery.

Other: Good Christmas Stocking filler for your 6 year old.

Pros: It works. I use it in a foldable Bicycle so it is good to have no cables messing around when you go into folding, but...

Cons: Keep in Mind that the max distance between receiver (the screen) and the transmitter is 50cm as it's stated in the user manual. This is a problem in foldable bicycles with small wheels. If you exceed those 50cm readouts becomes erratic or null.

Other: Having a wireless speedometer in a foldable bicycle is a good idea, but 50cm as maximum separation turns this device useless for this kind of bicycle.

Pros: It shows how fast you are going if you set it up right, however I can't tell if its really accurate or not, but I assume so.
Some of the computer features are cool such as telling you if you are going faster or slower than your average speed.

Cons: The computer things I'm moving at the weirdest times, such as when I'm sitting at my desk or if I'm walking and far away from my bike.

Other: If you want a cheap computer, get this. If you want a better one, try something else on the site or pay for one at the store.

Pros: Hey, the price is great and this unit appears similar to many of the way overpriced computers one finds in the typical bicycling store.
Still working after a couple of years.

Cons: I've had this for some time and still cannot figure out how to get it to calibrate properly. Thanks to another reviewer, there are images of the instructions which provide a chart for settings by wheel diameter. Either I am doing something terribly wrong or am able to cruise at 80kph.
The mini 12V battery in the sending unit was dead on arrival but easily replaced.
The receiver unit rattles a bit, which I suspect may be some sort of motion detector to save battery while not in use.

Other: Looks like it works great, but my trouble getting it calibrated seems to limit usefulness to being just a timer.
Hope others have better luck.

Pros: Has all the functions you need for biking. This is the exact same model they have in Sportchek in USA and Canada, just different packaging

Cons: The instructions are a bit confusing if its your first time installing one. If you need help, look up internet guides on how to install similar products

Other: This is a must buy. If its DOA, try and replace the battery. If still doesn't work, then DX will replace it.

Pros: - For those who enjoy a good ride this product is indispensable
- Good quality and suitable for any bike.
- Works perfectly.

- Para os que gostam de uma boa pedalada este produto é indispensável
- Boa qualidade e serve para qualquer bicicleta.
- Funciona perfeitamente.

Cons: - There is an LED to illuminate at night. So late at night, you can not see the screen.
[BR]
- Não tem um led para iluminar de noite. Portanto, à noite, não dá para enxergar a tela.

Other: Your ride will become much more fun and professional. Use and recommend!

A sua pedalada vai se tornar muito mais divertida e profissional. Uso e recomendo!!!

Pros: Very nice gadget, easy mounting and setting. shows time, speed, average speed, max speed, distance, and overal distance. it resets when battery changed, but can be set manually later. Stores info about last workout. shows if you going faster or slower than average speed. waterproof, can be used in rain, but not underwater.

Cons: a little short range between sensor and main unit ~60cm so doesnt work when mounted on rear wheel.

Other: Perfect bicycle computer, if you dont mind short sensor RF range this device doings its job very good!
