- Set up your display screens easily via smart phone app
- Contains all functionality that most cyclists will want.
- Does not include Di2 connectivity, but you need Di2 for this feature to work anyway.
- Comes with only a basic mount that attaches with elastic bands and not a mount that holds it out in front of the bike.
MSRP: Around $130 (depending on which model, E, H, T you purchase – see below)

Summary: Same price and functionality as its predecessor (Rider 410) but now with Follow Track/Guidance (but no maps).
What comes in the box?
After unpacking from the box, I plugged in my new Bryton Rider 420 so it could charge overnight. When I opened the Bryton app on my Samsung Galaxy S8 the next morning, I was surprised to see that the 420 was already connected.
In the app, I next went over to the settings and defined three pages of data so that it would display just like my existing Rider 530 was set up.
First was to define the data fields in the first page. I chose seven fields and easily defined them as (1) Current-PB-LR (current left and right pedal power balance), (2) Current-Pwr (current power), (3) %FTP (percentage of your functional threshold power), (4) CAD (cadence), (5) Ride-Time, (6) IF (intensity factor) (7) TSS (training stress score).
I defined the second screen as more of a daily riding screen and the third screen as a climbing screen. I then went in and defined a lap screen for interval efforts with a TIMER, PWR (current power in watts), %FTP (percentage of your functional threshold power), CAD (cadence).
That’s really all you need for actual training, in my opinion. The analysis can be done off the bike after you finish the ride using software like WKO, Training Peaks or Golden Cheetah.
Pictured in the photo above is my regular training head unit – the Bryton Rider 530, which I find to be comparable to the Garmin 810 at around half the cost. This unit has over 20,000 miles on it and has lasted over 4 years. And for the record, Bryton sent me one for each bike, so between them, they have around 40,000 miles. They have been rock solid, without a glitch or hiccup.
After programming the screens, I then paired the Rider 420 unit to my dual-power meters and to my cadence sensor. I am using the new Assioma Favero dual power meter pedals, another rock-solid product, the Bryton wireless cadence sensor attached to the non-drive crank arm and the unit’s GPS to measure speed.
In less than two minutes after I brought up the settings in the app, everything was paired and running! This was by far the easiest unit to pair of all units I have tested to date. Granted, I already had the app on my phone from setting it up previously with my other Bryton computer.
On the first ride, the unit woke immediately, and I saw everything was zeroed out. As I started pedaling, all functions came right up on the screen as I had set them up.
My Cervélo R5ca has Di2 electronic shifting, and the Rider 530 has a Di2 function which picks up data from the Shimano D-Fly (EWW01) transmitter. I use this function to check the Di2 battery level as well as can see what gears I am in.
I have my Di2 programmed so all I need to do is click the button located at the top of the right shifter to page through the different screens of the Rider 530. I hit the button a couple times, and nothing happened…. That’s when I remembered that Di2 is a feature that is not included in this Rider 420 unit. It’s just as easy to click the lower left button of the Rider 420 to change the display. The newest Rider 860 model supports Shimano Di2, SRAM eTap and Campy EPS.
The device is limited to nine data pages with a maximum of eight fields per page. With its smaller screen (compared to the Rider 530 or Rider 860), any additional fields would be a lot harder to see and probably cause information overload as the cyclist would end up squinting at the screen instead of looking at the road. I feel that eight fields are more than enough on this size unit to give you all of the information you need. If you need to display more than eight fields, then just split these in half and use two data pages and go back and forth.
The Rider 420 comes with a mount that attaches to your stem with elastic bands. Since I already had the out-front mount installed, I just used that. So the mount shown in the photo above is not included with the unit, but is available as an accessory.
Even though the Rider 530 is a larger unit that I am used to, the Rider 420 did not seem too small. All data fields were crystal clear and easy to read.
The Rider 420 supports 77+ functions under the main headings of Speed, Time, Lap, Power, Distance, Cadence, altitude, heading, Heart Rate, Temperature and Calories. Battery life is claimed to be 35 hours, and so far after a half dozen two hour rides, the battery indicator is starting to move.
For around $130, you get a rock solid bike computer with all of the functions you would use on your average ride. If you want even more features, you might then consider the Rider 450 ($200-$280), Aero 60 ($230-$280) or the new fully featured Rider 860 ($350+).
