Transmitters included for detailed data analysis

The BC 23.16 STS features a multitude of bike, altitude and heart rate functions. An altitude profile and a heart rate graph are created. In the Altitude view you can see data on the current altitude, current gradient, total altitude and the uphill/downhill altitude in feet. The current cadence, average and maximum cadence are also displayed. All 3 wireless transmitters are included.

Enormous log capacity

You can save up to 99 rides on your BC 23.16 STS. This results in a total logging time of up to 500 hours with a logging interval of 20 seconds

Power in Watts

The BC 23.16 STS calculates your current and average performance in watts. This calculation can be used to compare performance on different rides.

NFC & Sigma Link

The BC 14.16, BC 16.16 and BC 23.16 models can communicate directly with an Android smartphone via NFC (near field communication) and the free Sigma link app. For wireless data exchange, simply hold your smartphone next to the computer. The app can be used to modify settings and view trip data.

The data can be transferred from the smartphone to the Data center via the Sigma cloud. Conversely, it is also possible to transfer data from the Data center to the smartphone via the Cloud.

The free Sigma link app is available in the Google Play store. The NFC technology is only available for Android smartphones.

Customers say

Customers like the heart monitor feature of the cycling computer. They say it's a great device with annoying design features. However, some customers have reported issues with the performance and ease of use of the product. They mention that the transmitter didn't work to start with, the wheel sensor will only work with a special wheel magnet, and that the manual is one of the worst they've seen for a product like this.

5.0 out of 5 stars Wireless BC with heart rate monitor, cadence, gradient, and backlight. But maybe not Ghost Race
Reviewed in the United States on March 6, 2020
Verified Purchase
I love this item. I own three of this line 16.16 for my commuter, 14.16 for my MTB, 23.16 for my road. For all is these, I really like the NFC function to transfer the ride info to my app. FYI you can have up to 3 bikes in the app, even though your speedometer can only have two. You can edit it in the app after you upload. The NFC is tricky, but their video really helps. Yes, the manual is a maze, but I'm the type that doesn't need the manual to set my watch. So these items are for technical folks.

This one 23.16 is great for road biking because it has the heart rate monitor, gradient function for steepness, and cadence monitor. I didn't want a GPS computer because I already have a phone that I mount on the bike. Also I didn't want to charge it all the time.

Now there is one aspect I have to dock a star. The advertised ghost race function does not work for me. I hope this is fixed soon in the app. But even though I'm bummed about this, it still is the item for me.

** Update: Re-added the star. Not sure why now, but the ghost race works now. Perhaps the app got updated? Anyhow, that's what I wanted!

I'll also mention that it would be great if Sigma let's me edit the data. Sometimes the speed goes haywire, so it thinks I'm going 200mph. It screws up the graph when I review my trip. If I can edit it, then it'd fix that problem. In general, I don't have an issue with the measurements.

** Update: I find the Mac software to be great. I can almost update the data. You can select a range, but you can't cut out a range in the middle. I hope they can address that. Just let me edit the data. It's mine, isn't it?

I've looked at many wireless bike computers under $100. This is the only one with all these features I mentioned above and the app that I really like.

I should also mention that the customer service was very nice. I lost my manual and got mailed a copy.

So far this device does not work, I managed to get the HR monitor function going but that is it. I cannot get Sigma Link to work with my phone's NFC capabilities. W/O Sigma link this device is useless. I think I should have just ponied up another hundred dollars for a Wahoo or Garmin.

2.0 out of 5 stars SIGMA Cheaply made
Reviewed in the United States on January 16, 2021

This is my second SIGMA that has failed within a year. In both cases it seemed to be mechanical. The first unit started to lose the lap button - just popped out regularly. The second, this 23.16, lost the lap counter ability after three months of use. Press the button and nothing happens. I emailed Sigma in Germany for the warranty claim and they said to send it to Germany for fixing. I did, and checked back 4 weeks later and customer service rather indignantly asked "why did you send it to Europe from the U.S.? We told you very clearly not to send it because we can't take it because of customs." First USPS allowed the shipment; second, they absolutely said "please send to (our address in Germany)". Only the fine print in the warranty- not the email to me - said "European shipments only." My bad for missing that, but when I called them on it they stopped responding. No concern at all, no "we're sorry for the inconvenience." Seven weeks later, the item has not been returned to me so I'll go with Garmin now. Beware of Sloppy Sigma.

5.0 out of 5 stars Good computer great customer service!

I bought this computer as the idea of cadence, speed, heart rate, and an altimeter was very attractive. I am a little wary of wireless computers as I question whether the transmission of data will be consistent.
I had some issues with the computer early on but Randy Scott with Sigma customer service has been great and he helped me fix it.
The computer seems to work great during my outdoor riding. The data has seemed to be accurate and has worked for me although I'm not sure about the calculated watts, but it's a cool function.
I had a bit of trouble using the speed sensor on my rear wheel for indoor training but once again Randy Scott with Sigma helped me out. Over all a fantastic computer and I would highly recommend it to anyone. This 5 star rating is due to Randy as he has helped me work through an number of issues with this computer. Sigma you can thank Mr. Scott for this rating you got on your product.

3.0 out of 5 stars It can be annoying...
Reviewed in the United States on July 18, 2018
Verified Purchase
This is a pretty good device with some annoying design features. First, the front sensor has a 1/4' plastic hinge that is about as delicate as a potato chip. How long will it last before you break it off? For me, two weeks. I had a hard time finding it in my all-black back seat in my car...you'd never find it on the road or trail. Don't follow the directions to put it on the front of your front fork. Too easy to break off. Second, the wheel sensor will only work with a special, not-at-all-aero wheel magnet. Even other Sigma magnets won't work. And it's very sensitive to distance from the sensor. Third, the directions are written in hieroglyphics. You'll want to go online and download the full manual.

5.0 out of 5 stars Works on a recumbent!
Reviewed in the United States on May 21, 2019
Verified Purchase
Recumbents tend to have longer distances between the computer and the sensors. As a result, many wireless sensors don't function, or function intermittently. This setup has worked flawlessly on a recumbent bike.

Setup was pretty straightforward. A large instruction sheet is included, and is reasonably easy to follow. The only thing that wasn't clear to me at first was how to turn the unit off, but research showed that it has an auto-off timer and you cannot turn it off yourself.

Once on the road, it's easy to navigate to the data you want to display. While a lot of various data points can be displayed simultaneously, it remains easy to read and does not feel cluttered.

Totally illogical means of accessing performance data. Equally poor design of interface to access setup. The manual is one of the worst I’ve seen for a product like this. It works. But isn’t easy to use while riding or when stopped.

Had a problem with the cadence sensor, it would read sporadically. Tried repositioning. Read blogs. No improvement. Finally, pulled out the multi-meter and checked the cadence sensor battery. It tested at 2.8 volts. Popped in a new 3 volt battery (which tested at 3.22 volts). Problem solved. The computer's battery tested at 2.85 - changed it. Heart-rate monitor and speed sensor both tested at 2.96 volts. left those in. Sunny day. Great ride.
