CYCPLUS GPS Bike Computer, Wireless Cycling Computer, ANT+ Bluetooth Bicycle Speedometer Odometer IPX6 Waterproof, Rechargeable with 2.5″ Screen for Bikers Outdoor Cycling (New Upgraded)

The M2 slays. I used to ride motorcycles so it’s nice to see a round dial. It quickly links to the satellite. I’m surprised how accurate this is. If I’m moving the bike around my house with the unit on, it updates the speedometer, even if I just move the bike across the room. The app is integral and easy to use. Carry the manual with you until you remember what buttons to press to record, stop and store.

i like the readability its easy to see and this one you can set the odometer it has a c8 option for it i find this interesting as its advertised as not having the ability but mine has it which is cool the one issue i have is the temp gauge is inaccurate constantly reading temps between 87 and 95 degrees i even tried calibrating it by putting it in the fridge which brought the temp down to 44 then it rose slowly back up and again stopped at 87 degrees at the time of calibration outside temp was 76 my theory is it is being thrown off by battey temp overall this is very accurate with speed and odometer readings the temp is not that big of a deal but it would be nice if it worked i just received this today so if anything goes wrong ill update my review update the temp gauge finaly started working correctly i took awhile but it reads correct now everything is working really good i am happy with this computer so far and this is the white one which you also set the odometer it is c8 in options

After six months of happy experience with the small square CYCPLUS G1, I decided to move up and also use heart and cadence sensors. I bought both the round M2 and the rectangular M3 to try whichever fits my needs better. SETUP: The M2 can only be set up using its four buttons and the on-sceen menus. An owner of an M3 can choose between this on-device option or use the CYCPLUS FIT cellphone app to configure the device. I found both methods straightforward and easy. The only advantage of the app was that it also had an option to sync the time zone setting with the cellphone. I didn't even know that I lived in time zone -10. DISPLAY SCREENS: I do ocean paddling in an OC-1 (one person outrigger canoe) in Hawaii. The ocean has, obviously, unobtructed skies, and most of the time I paddle in sunshine or otherwise very bright natural lighting. There are almost always saltwater droplets on the screens and, with time, some crystallized salt deposits build up here and there. The computers are place near my feet just above the steering pedals about 4 feet from my eyes. I am not wiping the screens as they are not easy to reah and my hands ae busy paddling. The large speed numbers are always easy to see but the smaller numbers are more challenging. In sunlight conditions and wearing sunglasses, the black numbers on the white screen of the M3 have more contrast and are easier to read than the white numbers on the black screen of the M2. In addition, the small numbers of the M2 are so small that I cannot read them from a distance of 4 feet. I will try to mount the M2 closer to my eyes onto the cuff of my leash just above my knee, 18" from my eyes. I will update this review with my experience. I have one comment regarding the display of the M3. The numbers in the four customizable fields are only half as high as what the available space would allow. It would be good to have an option to see full-size numbers in those fields. THE APP AND THE GPS RECEPTION: The cellphone app cannot be used to set up the M2 but can be used equally for both models to download and analyse the collected data. I enclose a photo of the overview screens of the data collected by both models sitting side by side during an approx 7-mile trip off Hawaii Island. Both measured almost the same distances and heart rates. But surprisingly, the average speeds and paddled times are VERY different. 4.7 vs 6.4 MPH and 1:30 vs 1:09 paddled times. One must be awfully wrong, but which one? On the more detailed speed charts the horizontal dotted line is the average speed. We see that on the M3 chart this is way above all other speeds. The average speed is larger than the maximum speed. This is wrong. The reason is that during the trip, the M3 often lost the GPS signal for periods between half a minute to a few minutes. Then it reestablished the connection without any intervention and went on funtioning fine. During the off-signal periods the indicated speed dropped to zero and periods with zero speed are not counted into the paddling time. As the data show, the M3 was off the signal for almost a third of a 90 minutes trip. The device is defective and will have to go back to Amazon for a refund. I didn't have this problem with the G1 or the M2 and I plan to try a new M3 after I got my refund. I am not gambling on dealing with CYCPLUS customer service as they didn't reply to an earlier email about another issue. UPDATE (3/20/2026):I was told that the likely reason for the M3 to lose GPS connection is that this particular device was intended for the domestic market and set for the BEIDOU positioning system. Some similarly priced bike computers from other manufacturers allow users to choose between various positioning systems but not this one. My intended return for refund hit an obstacle. USPS in Hawaii is not accepting the GROUND / HAZMAT shipping label sent by Amazon. I cannot find any ways to communicate this to Amazon and ask for a USPS compliant label.

I have not had any problems with this. Does everything I need it to. It is not a Garmin but I did not pay that kind of money. Looks great on bike. Instructions are handy. Sync with strava and the app that is used with is it nice to. Update. I've had it now for about a year and it started to stop keeping time and distance well It became locked up around the 12 minute mark and 3 to 4 miles Which totally affects the app it'll run for a while and seem to do well and then not record the ride accurate.

This is a all a round great bike computer. It lasts a long time on a single charge. Did a 309 mile ride in the month of August for the American Cancer Society and never had to charge it. Great GPS accuracy and mileage.

I just can't recommend a GPS device that regularly inflates distance traveled by 20%+ (I saw up to 50%). I think it was okay in wide-open areas, but any trees and it became a problem. I never saw this with my CYCPLUS M1, which I loved but left at a trailhead. I wouldn't even care if it was just reported incorrectly on-screen, but Strava uses the distance reported by the device, not the distance of the track matched to its route data - and I want my Strava data to be accurate within 5% or so. It also wreaked havoc on Best Efforts and such (50mph+ averages for segments and the like). The screen is quite easy to scratch, but that can be mitigated with a screen protector. It's a shame, because there's so much else to like: it connected well to my heart rate strap and power meter, battery life is good, I love the form factor, and the screen is easy to read. Just can't recommend a device that doesn't perform its primary function well in most conditions. UPDATE: CYCPLUS support is responsive, and said they intend to make improvements in the next version.

Buttons Difficult to push when mounted, does not display. Trip time with seconds and does not connect to computer. Otherwise a very nice bike computer.

I regret buying this. GPS is inaccurate and is not user friendly.
