iGPSPORTBSC100S GPS Bike Computer Wireless, 2.6'' LCD Display 40H Rechargeable Waterproof Cycling Computer Bluetooth ANT+

It's easy to mount and looks great. The simple sunlight-readable LCD display (also backlit at night) reminds me of the old wired wheel sensor ones we had as kids, but it has so many more features packed into it. It has GPS, connects to your phone with bluetooth to their app which will link instantly with Strava, and if you want more data, can connect to any standard wireless speed, cadence, and heartrate sensors. Battery life seems great. I haven't run it dead yet, in fact any ride less than about 25 miles and it won't even drop by a bar. No comment so far on durability, but it's really lightweight and plastic, so I imagine a drop wouldn't hurt it. I did one ride in pouring rain and it's definitely waterproof. It's pretty easy to use once you get the hang of it, only has two buttons which do different things whether you're in a ride or not. The manual is pretty short and simple, maybe too simple with some Chinglish, but it gets the job done. One note: When they say diameter, they mean circumference ;) No routing capability that I know of and no fancy color screen with map, but low price and high battery life are the benefits you get by not having those things.

I'm pretty happy with this little gizmo. It automatically tracks my rides and uploads them to Strava. It gives me the info I need for my ride. It does not do GPS navigation, but I ride the same trails all the time and generally don't need directions.EDIT: I found one negative. It will not work while being charged. This is a particular drawback if you have an Ebike with a built-in USB port. It can save you the hassle of having to dismount it to charge it. If it worked while charging, you could leave it on the bike all the time and it would charge while you ride. Still, given the price and features, I don't think this drawback would be worth deducting a star.

Grabbed this bike computer to track my trips. It's been great.Installation is super simple and the mount is secure. Mounting the cadence and speed sensors is simple, attaching with rubber mounts. You only need to set your tire size and it'll accurately track your speed. Attaching it to the mount and removing it just requires a simple twist, making it easy to remove when you lock up your bike or need to charge it, but the computer remains really secure even when riding off-road.The controls are fairly simple, with just two buttons to control start-stop, scroll through pages, and more. The illuminated displace is easy to read, even in bright sunlight. You can configure the various elements through the mobile app on your phone. This is also where you can set various options like measurement units, along with setting things like stages. I love that I can connect it with Apple HealthKit to track all my workouts in a single place. I also have it linked to the Adidas app, which earns you points for workouts and Strava to map my rides. The built-in GPS goes a great job of recording my route and then passing that data to Strava.The battery lasts the week but even when not used, it seems to die over the week. To deal with this, I've set a Sunday reminder on the calendar to charge it. Then it's ready for the week. I wish the battery life was better but it's not a deal-breaker, especially at this price.Overall, this is a great bike computer that's easy to use, packed with features at the price point, and simple to install. I'm very happy with it and look forward to many more rides with it.

UPDATE: after about a month of regular use with the bsc100s I am happy to report that this thing has worked flawlessly. syncs to my strava fast and without issue. you can't beat this for the price IMO and I usually hate everything! also: paired it to my garmin wheel speed sensor no problem too!I've used garmin products for the past 10years and couldn't justify shelling out another $300-400 on another one after mine Edge died. non replaceable batteries in a $400 electronic device is absurd. same thing with their watches. what should cost about $40 in new batteries would cost me about $700 in new devices between my edge and my watch. absurd. and to be honest, I had CONSTANT issues with my edge anyway. syncing issues and the unit wouldn't even turn on half the time w/o having to do a soft reset. nothing more annoying than constantly having to deal with that, i dreaded it each and every ride.so thats what brought me to try this $44 bsc100s. and so far so good. no issues setting up the app- although all the permission you have to agree to is a little sketchy but whatever..., synced right up to my strava account, took it for a spin this morning for a short 8mile ride and no issues with its main function. saved the ride when done, synced within a few seconds to both my strava app and the igpsport app. I will update my review as time goes on but even if this thing only lasts me a year or 2 I'll be happy for the price vs shelling out the insane amounts of cash for another garmin device. word of advice, the included instruction manual is pretty much useless, scan the QR code in that booklet to get the full 14page manual online. here are my only 2 grips so far with the unit. 1. theres no way to combine your AVG speed on a page with your MPH. so anytime I want to see my avg speed while riding i have to push the right button to skip a page on the 4 page display and then i can see my AVG mph, then to see my real time MPH I have to go back to the page I was on, THIS was a pretty big bummer for me personally . 2. the fonts in the little windows are hard to read if you're like me and have compromised reading vision (the joys of getting old..). but I can deal with that , its not a deal breaker on the unit as with time I'll memorize what each of the 4 lower quadrants of the display are showing me . I still need to sync my garmin wheel speed sensor but so far I'm happy with my purchase. for under $50 you cant beat it IMO. and it's free returns anyway, so what do you have to lose. send it back if you don't like it and then go spend 4x the amount for the closest name brand unit thats comparable.
