Wasn’t that easy to install

The battery life is really good. Last over three years. It is very easy to use and set up. The only problem I had is after having it for five astonishing years. The cord on the backside of the attachment broke very good for $12. Highly recommend for your kids or young riders.

I used this on my bike during the winter on a trainer to track miles, speed and odometer. I put the magnet on my back wheel.

Easy to set up & install. Everything you need is in the box. Worked great first time out on the trail. Had some issues on the way home though. Immediately contacted seller. 'Ron' responded quickly & issued a replacement. So far, satisfied with value & customer service.

As the photo shows, the specs are so ridiculous-2mm-that I had to jury rig a spacer to make this POS work. It's good that I'm only using it on my bike I've put in rollers to keep track of miles. Otherwise, I'd be returning it cuz it'd be utterly useless on the trails.

This is my first bicycle computer so I cannot compare it, but I like it very much for what it does. To have bicycle speed,average speed,odometer,trip meter,temperature and time on display is a benefit to cycling. All that for the price is good value. It does take a bit of time to figure out how it works. Install was straightforward. After install I was curious as to the accuracy of the device. As I found out,this all depends on the number you enter for your tire circumference in millimeters. Initially I used the included chart. Where I ride there are milage markers and mine was off about 50 ft per mile. This was too much for me. I rode 7 miles with a 350 foot error. Here is how I fixed it to bring the accuracy within the resolution of the device which is approx. 5 ft/mile.Find a flat surface and lay a tape measure down for 25 feet or so. Using a piece of chalk mark the tire and the surface you are rolling on as zero. Then carefully count the rotations of the tire,I did 3. Take that liner measurement along the ground surface and divide it by the number of rotations to get your actual circumference of your tire. The more rotations and longer the distance the more accurate you will be. If you measured in inches, then convert it to millimeters. Round it to the nearest whole number and enter this into the device. This worked great for me.

I've been training with this for a few weeks now, and I've just barely got it dialed in well enough to be useful. If you're looking for something that's quick to setup and use, this likely isn't going to work for you. Installation wasn't as smooth as it should have been. Getting setup on my mountain bike was a bit more effort than I think should have been necessary. I had to cut out some Styrofoam from some packing material I had from another product I ordered in order to get the sensor close enough to the magnet to pick it up. Going through the initial setup was a bit more difficult than it really should have been too. You have to put in the wheel circumference (in millimeters), this is expected. The weird thing is that you do it backwards. You start with the ones place, then work your way out to the thousands. I didn't realize this the first time and went to cycle through the digits a second time, and nope, you only get one shot. You have to do a hard reset to set it up again (hold both buttons for about 10 seconds). Don't use the included table, it's wrong. My bike has 26x2.0 tires on it, I matched it up with the table, and it was wrong. I used a metric tape measure and got my wheel diameter, did some math, and it came out substantially less than what the table says. Once I put in the correct value though, it has been pretty spot on.

I needed one with wires as wireless ones have such pathetic range. This one had enough lead to do the job.

My first was faulty and the seller was very kind and gave me a second delivery at no extra cost. 5* customer service!The speedometer itself is slick. Standard left button to freeze recording and right to cycle through menus. It even has a thermometer!Only grievance is there is no backlight, which would be nice. Other than that, it's a quality piece and easy to install and remove when locking up my bike.

I run this speedometer from the rear wheel of my bike on a turbo so that I can cycle indoors because of bad weather and the covid lockdown. The unit was fine for the first couple of weeks but then ceased to register speed after 20-30 minutes of exercise, and then shut down completely. The unit itself and its battery are fine, but the problem lies in the leaf-switch, which seems to become magnetized after 20-30 minutes of constant pedalling. This closes the switch's blades, and so no signal can reach the unit. The problem resolves itself after a rest, but that's of no use to me, as I want to monitor my exercise for an hour at a time.I have fixed matters by getting a better magnetic switch from Amazon that I've wired to an old cable from the shed. However, the speedometer assembly that's sold (handlebar unit + switch) was not fit for my purpose. I could have saved money in the first place by buying a similar speedo from our local Home Bargains for £3!

I purchased this item in November (a little over two months ago), as I had previously tried a wireless cycle computer which I found to be a total waste of space. That item was from a different seller on Amazon, so nothing to do with this one. Back to this item, it works fine if you only cycle in dry weather. Unfortunately, I live in England, so often find myself cycling in the typically wet British weather as I use my bike for work and leisure on my days off. As soon as the rain starts, the speedometer stops working after a couple of miles. Very disappointed to be honest and would NOT recommend this product if you're an all weather cyclist like me. After a wet ride home tonight, this item really is only fit for the bin!

This vendor has contacted me 3 different times, wanting to make sure I'm happy. From the tone (and purpose) of their emails, I can tell they truly CARE. That's nice to see. And it hasn't been like some vendors, who are using their 'follow up' emails as just a way to get the customer to do a review. So I would definitely do business with this company again.This computer went on my secondary mt. bike, which I ship from one coast to the other, for some island biking events I participate in. Mounted it up, pretty fast, as most of these computers install the same. I don't recall using the included instructions, other than using their calibration chart for inputting my tire size. Installing bike computers is sorta like setting up a smart phone .... once you've done it a few times, there's really no need for 'instructions'. Or maybe that's just a 'guy thing' ? I've got a nearby neighborhood radar (speed) detecting sign, so I was able to test my computer, and check the mph readings. Was spot on, by using the instructions' calibration chart. Everything else seems to work great.Display unit is a nice size. Not too big or too small, and has an easy to see readout display. The color of the unit is white, which I thought might stand out too much. But it looks fine when placed on any of my bikes (of different colors). I won't go into various other technical details about this unit, as I haven't ridden with it long enough, to assess the accuracy. But for the price I paid, this unit works great.I've owned plenty of bike computers. Too many to count, but that's a good thing, as it's been due to owning plenty of bikes. Both wired and wireless bike computers, of different brands. Rarely paid over $30, as it's not really necessary, unless you are the weekend warrior who enjoys tons of data, or are very hard core about what's going on during your workouts. I've been in both of those groups, yet I'd rather spend my money on other things than a $+150.00 - $ 300.00 bike computer.Most bike computers install the same way, and you just need to load in the proper tire size to make it read accurately. Adjusting the sensor's distance to the receiver, is where most folks might have problems (getting their computer to work). I've had to play around with most computers, to get them to do a readout. But once it's set, you're good to go (unless it's getting banged into things). Patience and experimenting are important. Of all the bike computers I've purchased, I've probably only had to return two of them. So when I read negative reviews on bike computers, I have a feeling that some of those folks didn't have much patience, when setting up their bike computer. It's not complicated, but sometimes it takes some adjustment.Buy this computer, as I think you will be very happy with it.
