Q & A

1. You'd better measure your bike directly with a ruler to get more accurate data before use.

2. Your riding data will be cleared once the battery is replaced. So you are supposed to reset the program after you have installed a new battery.

3. To reset the program, you just need to simultaneously press the two keys for 3s at the same time.

4. The bike computer is of a function that you can switch kilometer to mile as you want.

5. Only on a condition that the wireless sensor and the odometer must have power at the same time can the bike computer work normally.

6. There may be a very small number of products in the transportation process will appear battery dead, if the battery is dead within 3 months of use, please contact. We will help you solve in a timely manner!

Usually don't post reviews but I'm really upset over this device. Got it a few months ago and had trouble setting up, finally got it and worked good.I had the holidays and didn't bike for a few months, just sitting. Now the device that tracks the wheels went jut all of a sudden. It was literally in use for 3 hrs. Ofc the manufacturer has no site to get a replacement or reply.It's sad because it felt like it was the perfect device but in the end a waste of money.

New unit. Stops functioning for 2 min. daily, then comes back on. Checked sensor and magnet gap, ok. As long as it comes back on, I have no problem. Must be a normal thing I have to start expecting from foreign goods. Disconcerting. A mechanical American made speedometer won't fit my wheel. Its just for reference, not needed for bike functioning.

It is easy to read and was not difficult to install. There is not a lot of information about resetting the counters. Then it gave me and error message that I have not idea what to do with. I would like to start the distance to zero on each new trip. UPDATE: I still dont know what the error message meant, however the counters is resetting. It does not work when riding the bike. I would forget to reset it and ended needing to reset it on the fly as I was moving apparently I have to be stationary and then you hold it for 3 seconds then it will work. So glad it's working well just wanted to follow up. NOTE: Wish it had a light for riding in early morning hours and for safety.

The computer itself is very well thought out and easy to view, program, and use. The large buttons positioned under the display is very user friendly. My size tire (27.5x2.10) wasn't listed in the instructions, but no worries, if you measure the circumference of your tire with a sewing measuring tape (in millimeters), you have your number (seems to be more accurate that measuring ground with 1 wheel rotation). My only issue is the transmitter distance is NOT accurate. The maximum distance seems to be around 24 inches. I bought this product because I have a 'comfort bike' so my handle bars are a longer distance away from where the sensor is mounted than say a mountain bike. I ended up placing the computer on the top tube close to the head tube. It takes a little more time to look down than would otherwise be the case if mounted on the handlebars, but it works for my needs. If the computer itself wasn't so good, I would have returned it. If they fix the transmitter distance issue, they would have a winner on their hands. I hope this helps.

Mounts easily, using wire ties and rubber backing. The magnet reader has a small rubber backing you stick on, then wire tie to your wheel supports. This keeps the mag reader from shifting around. Once mounted, the mag reader is adjustable, to allow you to get it close enough to the wheel magnet to work. There is also an activity indicator showing wheel motion, so you know you have things working.The display unit has a rubber insert that fits inside a mounting hole on the display, and is the full size of the units contact point on the handlebars. When you use the included wire ties the display unit held in place with no movement. The display can be mounted on the center post, or handlebars, I mounted mine on the center post, was simple and quick. The display unit is easy to read while in motion, even the smaller display sections. I am very happy with the device, and would buy it again, after seeing it. It is a very nice device for the price.Pros:1. Mounts easily, took about 5 minutes.2. Easy to read while in motion.3. Programming was simple.4. Touch sensor on top of unit for internal light. (Great for dusk to night use)Cons:1. The mag reader needs to be within 1 or 2 mm of the magnet, not really a big issue, but it worries me to have them so close. I have had zero issues along this line however, so probably not an issue.2. Touch sensor on top of unit for internal light. In daylight if you accidentally touch the top of the unit, you turn on the light. If bright sunlight, you can not see the light, so you don't know it is on. This increases battery drain. They do warn you about this in the instructions.I lost the manual, and have sent in a request for a replacement to download. I will post the results of that request here.Overall I really like the product, and it seems to be a solid device. I can press the button while riding, and the unit does not shift around at all, it is very solidly mounted using the included wire ties.Edit: I wrote the company regarding the lost manual, I got a copy of the manual via email from them within 24 hours.

This Speedometer/Odometer is a great price for someone that just wants to know how fast they are going and how far they went.Once installed, the unit worked great, however, the instructions need some work, so I included photos of the finished product. Especially the sensor and spoke magnet proximity. That was not clear in the instructions, so please take a look at the photos.Please note that the unit DOES NOT come with the screw on mount as shown in the photos. My wife had a basket attachment, so I modified the mount received to screw onto her bike, versus the zip tie mounting provided. I am sure the zip tie mount will work, but this was more permanent and made sense considering her basket bracket was in the way.Once I figure out the spoke magnet and sensor, this thing works flawlessly. Turns off with inactivity, and starts up with a couple of wheel revolutions.She likes it, and it does exactly what is needed, plus more. Our main reason for purchase was Speedometer and Odometer, which work great!!
