First ImpressionsNicely presented in little cardboard case;computer with a spare CR2032 battery, sensor with 23A battery pre-installed, handlebar bracket, 'O' ring, 6 cable (zip) ties and a multi-language 'manual' (big sheet of paper). Amazing value for a little over a tenner.However, the manual lets it down badly, the English text is decipherable but the explanations are inadequate. Like some other reviewers, I wasted a lot of time attempting to set the Time (of day) correctly, eventually stumbling upon the correct procedure:-Set-up.It's essential to grasp five basic concepts before starting the set-up process:1. Setting up is a single continuous process and you can't skip any single step;2. The value for each setting is set starting with the least significant digit (units first, then tens, hundreds, thousands or minutes then hours), logical, but in effect writing backwards.3. Values can only be increased (with the “RIGHT”button), I discovered that holding “RIGHT” down causes the minutes figure to count up at a rate of about 5 per second.4. “LEFT” button performs two functions: move one digit to the left (e.g. from tens to hundreds, or, having set the highest digit, Register (enter) that setting and move on to the next setting.5. Perversely, to set Time (after setting Km/h or mph), you have to hold “LEFT” down for 2 seconds (>1.5s and <2.5). If you just press “LEFT” it drops out of Settings into ODO mode. The functions of "LEFT" and "RIGHT" are now reversed:- "LEFT" increases the value, and "RIGHT" moves from 24/12 to Hours to Minutes to 'Register'.When you have made a hash of setting the time, you MUST cycle through the functions (by repeatedly pressing Right button) until the display shows Speed plus Clock. THEN hold down both buttons for 3 seconds to re-enter the Settings mode. You can cycle through Circumference and Km/h or mph steps without changing those settings, by repeatedly pressing “LEFT” - not too fast.Installation.On my Dahon Speed 7, the instructions “install the sensor as close as possible to (the top) of the forks”, “the clearance between the magnet and sensor must not exceed 4mm” and “the sensor...maximum range (of) 60 cm” are mutually exclusive; there's no way, even if it were possible to mount the sensor on the inside of the forks, to achieve the first two requirements. The only solution was to mount the sensor close the bottom of the forks, thus putting the magnet close to the axle (see photo). This gets magnet and sensor close enough to work (with the computer on the ground). To my considerable surprise, the computer then worked fine mounted on the handlebars some 80cm away! That may not sound like much of an increase, but signal strength falls as the square of the distance - the signal strength halves with a 40% increase in distance between transmitter (sensor) and receiver (computer). It may be a different story when the sensor battery starts to get a bit tired – we'll see what happens.The computer mount fits the Dahon's skinny handlebars surprisingly well, I simply doubled the rubber 'O' ring (as you would with an elastic band) to get it tight enough and added a single cable tie loosely so that, when the 'O' ring fails, mount and computer won't get lost. If I end up having to mount the computer on the bike frame, the 'socket' half of the mounting can be rotated 90° in the 'clamp' part by relocating 4 small self-tappers in an alternative set of holes.In useAlmost non-stop rain since it arrived, so far I've done little more than get it set up (eventually) and fitted to the bike. Will add my riding experience in due course.

I'm quite disappointed with this bike computer.I've identified 3 issues that bother me:1) When riding in the dark, the LCD can be lit up by touching any button, but by doing so it also changes the function associated with that button. For example I like to keep total daily distance selected as I ride. If I want to see the current reading at night, i press the button, the LCD turns on but the next function is showed, average speed. It takes pressing the same button 5 times to cycle through the options and go back to the option wanted.2) The LCD light turns on only after 6pm. In the winter commutes back home as it's dark after 4pm, I can't use it.3) This computer didn't last 3 months in UK winter weather. Most of the LCD can no longer be read because of water infiltration. I'll be trying to get a warranty replacement!In short, avoid.EDIT: I got a warranty replacement. lasted 2 weeks and one of the buttons already no longer works. changing from 2 to 1 stars.AGAIN, AVOID

Bought one of these bike computers last year and really liked it, it did everything that I needed. But the first bike ride I went to do this year it wouldn't work at all. Tried new batteries and the clock part was fine but nothing from the sensor. So because I liked it and only costing a tenner I bought another one. The very second bike ride and the clock "froze" on me. Got home and checked everything (battery, magnet distance ect. ) but again the sensor just wasn't working. About to give up and then it unfroze itself and started to work again but I have now lost all confidence in it. Have bought two but will not be buying a third.

I haven't had a cycle computer in quite some time, I was surprised to find it's wireless.This thing is brilliant, just setting it up was easy, using it while riding is wonderful. The buttons are big enough to press without any issues.And the screen is so clear.I managed to get it nice and close to the handlebar grips, so I didn't even need to take my hand off to check my speed :DIt has a scan feature, where every 4s it switches to the next display. This is wonderful.I would totally recommend this product and have already to several people.

Bought this as an Xmas present for the daughter and her new bike, resonably well packaged and comes with all the bits you need for install, including two batteries, plenty of features as well and simple to use and set up between speed distance stop clock, there are a couple of issues tho,Couple of issues , the part that goes onto the bikes spoke is pretty naff and plasticy, comes loose and you are scared to tighten it as it feels as if it's going to break,Secondly , the thing doesn't turn off! ( hence the two batteries I guess) usually these turn off after a period of inactivity, not this one, instructions say nothing and no matter what number of buttons and sequences you push it stays on,
