Bike Computer with Wireless Heart Rate Monitor Speed Cadence Sensor 38-funtion Bike Speedometer Odometer Backlight Altimeter (DCY438)

After researching Cycling Computers that had the various features I wanted, and price I could afford, I finally settled on Dream Sport DCY 438. While Computer came with installation instructions and good manual, I like to download the information as well. So I contacted the Company web site, asked for the download and expected to maybe hear from them in weeks, if at all. To my surprise, the download was waiting for me the next time I turned on my computer! But wait, there's more... During the installation, I dropped and broke the cadence sensor. Wrote to Roy, the contact person at Dream Sport and asked for a replacement. He said he would find one for me and send it right away. Just received it, and installed it. No problems... This computer has 4 modes and a multitude of menus for each mode, along with a Heart Monitor. I now have more access to information than Eddy Merckx ever had! If you want a computer that is affordable, accurate, and has great service folks, this one is it.

This was sold as a new product but was previously sold and returned. When I received it 4 batteries were already installed and 2 more were in the package. I replaced the 4 installed batteries with new ones and installed the computer and both sensors and put on the HRM. After going through the setup procedure (e.g. clock, wheel size, etc.) I rotated the crank while my bike was on the bike stand. Everything seemed to work perfectly except the B button changed modes (bike, altimeter, cadence, HRM) and the A button scrolled through options in that mode. This was opposite what was shown in the instructions but not a big deal. Then I touched the rear brake to stop the wheel, and I noticed the computer reset itself. I went through the setup procedure again and turned the wheel. Again everything seemed to work perfectly, but the computer eventually reset itself. I went through the setup procedure again with the same result. My conclusion by now was that I had a defective computer. I suspect this was why the computer was previously returned (remember the 4 installed barrettes). I did not try to contact the seller for two reasons. First, they did not believe the previous purchaser or they would not have resold the defective computer. Thus, there is no reason to think they would believe me. Second, this was sold as a new computer. It was not! I returned the computer (thanks Amazon) and ordered a different one with a better rating. BUYER BEWARE!

for the price, I am quite happy. The sensors are bulky and can be tricky to place. They NEED to be VERY close to the magnet to pick up signal, so placement looks like it could interfere with wheel depending on the bike- mountain bikes in particular, but i have not had any problems as long as you secure it firmly. As far as navigating through the menu- its no more akward than alot of other high priced ones, just have to READ INSTRUCTIONS and learn navigation. Heart rate monitor is pretty much spot on accuracy, as Ive compared it to other heart rate devices. As far as people complaining about not being able to reset the trip mileage without resetting the whole thing- not true. Either they have older or defective unit or more likely just not READING INSTRUCTIONS. I've had Cateye computers in the past- this is just as good considering the price point.

This is an interesting bike computer, it includes three sensors: - Speed - Cadence - Heart rate monitor Mine came with all the batteries (CR2032) installed, one of the batteries was dead (the one at the HR sensor) so I have to change it (not a big deal). The installation is simple but in my case, I have to put the computer on the handlebar; I tried it on the stem but: it never received the speed sensor signal, and it was difficult to remove. Heart rate monitor length 90 cm (without stretching ) Update 2021-12-05: ================ The heart rate monitor battery drains when is not in use, so, looks like you have to remove the battery if you don't use the HR frequently. That's not practical. Update 2022-05-15: ================ I was contacted by customer support, and they replaced the HR sensor at no cost, the new HR Sensor works as expected; the battery was installed when I received it and it was working at that point, 16 days have passed since I receive it and the HR Sensor battery still working.

The problems below reflect my experience, and my guess is that the first main unit was defective. On the second--I was trying to install the computer on an adult tricycle and it appears, given that I got another brand to work, that the distance between the handlebar and the speed sensing unit was too great. Perhaps the instructions might note that the main and sensing units need to be within a given distance range The first one I could not get record speed and distance, it did pick up heart rate initially, but that stopped after a couple of rides. After reading some of the reviews I put in new batteries, but that did not resolve the issues. I returned it for a replacement. The second one seemed to be working, but the speedometer stopped after the first 100 yards of the first ride. Again I changed the battery in the speed sensing unit, but that did not resolve the issue. I returned this one for a refund.

I was disappointed in this bike computer. I originally just wanted to track my speed and the time of a bike ride, however I was tempted to get this one because it also does heart rate and cadence. That made the display and setup more complicated as I found out. The buttons are hidden away in the case so very hard to find and press them, making the setup difficult. I started with just installing the wheel speed sensor and never got any further. It just didn't work. The instructions are tiny so an older guy like me needs a magnifying glass and there is no download of the manual on their website. The pictures (pictures only for the installation) showed 2mm distance between the sensor and the spoke magnet, or peddle magnet for cadence. There is no adjustment to make that happen. The best I could do was about 5mm by moving the spoke magnet and sensor down near the hub. It still didn't register spinning of the wheel. I tested the batteries and they were 2.3 volts so I replaced them with new 3 volt CR2032's. I also tried the reset button on the sensor. Still didn't work. Was it the sensor to spoke magnet distance, the sensor to computer distance or something else? I lost patience.

Heart rate and simple functions. Also video they provide ! Good company !

What a great little unit, I was so excited to receive it, so many functions and pretty darn easy to install once you understand the directions. My only issue, but it caused me to return it, was the speed sensor won't work with my e-bike. When I turn on the Bafang motor the speed sensor doesn't see the magnet. I tried both front and rear wheels. The heart rate monitor worked without issue, and I didn't bother with the cadence sensor.
