Bryton Rider 420 Review SpecsBryton Rider 420 Review

As another new Bryton bike computer hits the shelves then so does another Bryton Rider 420 Review hit the internet. We start off with a summary and the pros and cons before quickly delving further into the details that some readers might be even more interested in. With the 420 you do, after all, get rather a lot for your money.


Well-featured, well-priced bike computer
  • Price - 95%
  • Apparent Accuracy - 85%
  • Build Quality & Design - 80%
  • Features, Including App - 90%
  • Openness & Compatability - 90%


A revamped exterior case and the addition of links to 3rd party sports platform like STRAVA is a welcome move from Bryton. Add in the ability to create, sync and follow either your own routes or 3rd parties routes and many people might raise an interested eyebrow. But it’s the price that will make you really sit up and take notice.

For one hundred and a bit $/£/Eu the Rider 420 clearly is not going to have every advanced feature ever created. But it really has got several of them, like the ability to pair to an ANT+ power meter for a start. Those sorts of features were once only in the realm of Garmin devices that were twice the price.

The format and interface to the Rider 420 are limiting but Bryton has done a reasonable job of beefing up what the Rider 420 is capable of by piggy-backing on extra functionality via the Bryton Active app, which actually works quite well now.

The navigational features do a sound but rudimentary job. Having said that, an upcoming cue sheet for TBT instructions and an upcoming elevation profile gives you the comfort that the basic navigational features that most people need are included.

Oh. And did I say it supports structured workouts sync’d from Training Peaks? Well, it does. Mostly. (If you have no idea what that sentence means then rest assured that it does some pretty advanced stuff 😉 )


  • Good price
  • Good feature set
  • Clear screen
  • Great sensor support
  • Claimed 35 hour GPS battery life
  • More than sufficient GPS accuracy
  • Feels well-made for the price
  • Structured training support
  • Nice 3rd party platform support (STRAVA, RwGPS, KOMOOT)
  • Did I say PRICE?…I’ll say it again…PRICE.


  • Could be prettier, the unusual shape is an acquired taste
  • Two buttons on the underside are hard to use
  • GPS-Compass only works when moving. It’s NOT magnetic.
  • App could be improved but it does the job
  • Bikenav functionality does not include re-routing intelligence or any kind of onboard map (but that’s a relatively normal omission even at higher price points)
  • The trade-off for the low price is that a lot of the navigation abilities rely on the Bryton app. Don’t like that? Then buy a more expensive solution!

Bryton Rider 420 – The Best Bike Computer?

This is a GOOD PRODUCT and has made its way into my Best Bike Computer 2019 list as the best bike computer for COMMUTING. The Rider 420 doesn’t do anything particularly unique…instead, it does LOTS of things for a RELATIVELY low price. For example, it supports Turn-by-Turn guidance with street names, Galileo GNSS, dual-band sensor support and power meter calibration and configuration.

Bryton Rider 420 ReviewPreviously this sort of spec from Garmin or Wahoo would be well over $/£200 but the Bryton Rider 420 usually RRPs at a reasonable price tag below £130/$150. However, if faced with a Wahoo Elemnt Bolt or Edge 520 Plus on sale at £150 I’d go with those but for a Rider 420 on sale at somewhere closer to £100/$100, then it becomes a serious budget contender for your hard-earned dollar.

Bryton Rider 420 – Headlines

I’ve highlighted some of the key features as I see them. Such features are typically only usually found on more expensive devices.

  • Follow Track – route following feature with TBT
  • 35 hours of battery life
  • Power Meter Pedal calibration (static calibration and setting crank length)
  • 80 functions
  • 2.3″ screen
  • 8 metrics per page, 9 pages
  • STRAVA, KOMOOT, RideWithGPS auto-sync routes
  • Create Routes on the Bryton app
  • Structured workout creation and sync FROM Training Peaks
  • BLE and ANT+ sensor support for HR, cadence, speed and power (ANT+  power meters only)
  • Bundle options starting at $130.

Bryton Rider 420 vs Bryton Rider 410

The Rider 410 and the new Rider 420 are highly similar. Even the prices should be about the same at RRP, although the 410 is currently on sale at Eu30 less. However, these are the differences to be aware of:

  • The Rider 420 has the same screen but a slightly smaller case 49.9×83.9×16.9mm vs. 53.7×83.9×18.2mm. The 420 is 4g lighter @67g.
  • The older Rider 410 has a more traditional shape with rounded edges whereas the new Rider 420 has unusual, angled off edges which I don’t like.
  • Bryton claims the 420 has 80+ features whereas the Rider 410 has 70+ features. I didn’t count them.
  • Whilst both devices can have 8 metrics per page, the 420 can support 9 data pages (vs. 7)
  • Route and Workout data cannot be sync’d from the 3rd party platforms Strava Routes, Komoot, RideWithGPS, TrainingPeaks to the Rider 410
  • The 420+Bryton Active App combo also allows the Rider 420 to support route planning and route guidance with TBT on the 420.

Bryton Rider 420 – The New Stuff in more Detail

Let’s look at the route and POI creator.

Route & POI Creation

From the screenshots further below, it’s hopefully clear that ALL the route planning is performed on the Bryton Active app which itself is aesthetically pleasing.

You can import routes manually or you can sync them in automatically from RwGPS, KOMOOT and STRAVA. Which is great. You can even filter the routes on the app to just show those from a particular service which does help you find the particular route you are looking for amongst potentially hundreds of routes you’ve created in the past.

Bryton Rider 420 Review

You can also create and then sync NEW routes via the app and that would also work if you had both devices with you when riding.

Looking at the app in more detail, the map type that I’ve shown below, in the slideshow, is the only one and you can plot your route on it manually, point-by-point or you can search for an address to automatically route to. Route choices are made for either MTB or road cyclists, however, as usual, many routes that cyclists often take are not chosen because they might be classed as pedestrian-only (that’s a problem with the map).

The Bryton routing solution is really only for relatively straightforward routes as it is difficult (impossible?) to edit the points you have laid down.

The following images also show how I have added some POIs to the route. These must all be done manually as there is no map layer which brings in the POIs…again that’s only fair for a low-priced navigation bike device. There is a little blue slider at the bottom of the map which drags a point along the route as you move it from left to right and when you are at the appropriate point you drop down the POI and give it a classification and name. It actually works quite well, although my recommendation would be to use a more powerful route creation tool like RwGPS and sync your route TO the Bryton. Clearly, if you are in the middle of nowhere then having the Bryton option as a fall back is very handy.

You have to then remember to manually sync your route to the Rider 420, which is a mini-PITA.

Here you can see the same route on the Rider 420 and it’s just a simple breadcrumb-like route. If you go off-course then you only have a compass heading and/or your position on the screen relative to the line as means of getting back on track. Meaning that the Rider 420 can NOT re-route you intelligently back to your route. Again, that’s normal for cheaper devices like this and also normal even at twice the price.

In the following image, you can see a comparison of the rudimentary line-route of the Rider 420 with the beautiful map on the Hammerhead Karoo to the right and the mystery device to the left with OS Land Ranger 1:25,000 tiles that can also be shown in 3D! but each of those two devices is AT LEAST twice the price and with poorer battery life.

Bryton Rider 420 Review

Following a Route on the Rider 420

I survived for many years by following breadcrumb routes, sometimes over quite complex routes. It was fine for the relatively infrequent number of times that I needed to follow a route. If my kind of usage describes you then you’ll be fine with the Rider 420. Actually, the Rider 420 is probably a tad better than some of the devices I used a few years back as it also pops up Turn-by-turn instructions which sometimes have the road names as well! I’ve shown an example of that below.

There are various audio alerts and you can also see a compass heading. The compass is a GPS compass and so that is only reliable when you are moving. Again, that’s normally fine as long as you understand the limitations.

Structured Training on the Rider 420

This is a surprising addition at the price point. I was impressed to see the ability to download my pre-canned structured workouts FROM Training Peaks so that I could follow them on the Rider 420. I could also create my own structured workout and store both types in the Bryton workout library. These workouts will NOT control the resistance on a smart trainer…but hey, what do you expect for the price !?!


Bryton Rider 420 – GNSS/GPS Accuracy

I’ve had the Rider 420 for over a month. I’ve generally used GPS+GLONASS but the performance is similar with either GPS-only or GPS+GALILEO and the performances were all probably good enough for cycling. GLONASS was perhaps just a tad better but using it will probably shorten your battery life

Here are two slideshows of 10 images.

Example 1:

Here we have a GPS+GLONASS performance for the 420 (blue) compared to the Garmin Forerunner 945, Wahoo Elemnt Bolt and a few other mystery devices (stay tuned!). There is nothing to comment on.

Example 2:

This is a GPS-only performance and, at times, I was closer to buildings than in the previous images which seemed to cause the Bryton some issues (Orange).


Sadly for Bryton, few people will probably read this review and fewer still will probably buy a brand they’ve never heard of.

I’d never buy this for myself as I am in the market for more advanced performance devices, rather than bikenavs. Plus I’m always a sucker for a pretty bit of tech like the Hammerhead Karoo.

However, what you get for your money with this Bryton Rider 420 is GOOD. Whichever way you want to compare the functions of the Rider 420 to other devices it’s good. The Rider 420 probably would win on very many people’s comparison criteria, providing you only judge other devices at the same price point.

I know I keep labouring the value-for-money perspective of this Bryton…the reason for that is that, although I ‘m a sucker for a pretty bikenav, I’m also a sucker for good devices that are good value.

Price, Availability & Discount

As 2019 draws to a close, the RRP for the Rider 420 is around Eur/$/£ 130.

As of now the Rider 420 is not fully distributed to all its intended countries and retailers. So the relative lack of supply will probably mean that discounting will be limited.

However, looking forward in time to Spring 2020 an onward I would expect you can shop around and get one of these for Eur/$/£ 100 and probably even less than that when Black Friday 2020 comes around. The green image, below, links to several retailers in your country from which you can choose your favourite or do a bit of comparison shopping.

  1. Hi there,
    I recently purchased the Bryton Rider 420 and I am having difficulty in importing GPX files I already have downloaded on my laptop, I use ride with GPS and I am at the end of my tether!, the instructions say to input the GPX files into the “extra files” folder, but I cannot find this folder what so ever, whether plugged into my laptop or on the device itself. any advice would be grateful, I have been in touch with Bryton but they just send the instructions which are printed on the manual

    1. Hello Dave, please try following the instructions below to import the GPX file. The instructions that you are seeing for the “Extra Files” folder is used for older devices and will not work for the Rider 420 🙂 . We have made it easier than ever to import these files using your phone:

      Before trying to import a GPX or FIT file route into Bryton Active, please ensure that the Bryton Active app is running in the background and that you have already connected a Bryton device that supports this feature.

      1. Download desired GPX/FIT file to your android device. (If you already have the file downloaded, proceed to the next step).
      2. Navigate to the Android file manager and locate the downloaded file.
      3. Press the file and select “open with Active”.
      4. In the Bryton Active App, name the file and save. This route will now appear in “My Routes”

      *Please note: After importing route, name can no longer be changed. When importing routes, results may vary.

      1. Download desired GPX/FIT file to your device. (If you already have the file downloaded, proceed to the next step).
      2. Open the “Files” app and locate the downloaded file.
      3. Press the file and select “open with Active”
      4. In the Bryton Active App, name the file and save. This route will now appear in “My Routes”

      *Please note: After importing route, name can no longer be changed. When importing routes, results may vary.

      Upload Route to Device:
      1. In order to send this route to a compatible device, return to the “Course” tab and select “My Route”. The imported route should appear in this list.
      2. Select the desired route and then press the send to device icon in the top right of the app. (Please note that it may take a few minutes to send the route to the device depending on size and complexity).
      3. After sending the route to the device, it can be found in the device menu under “Follow Track”>”View”.

      You can also follow the instructions in this video:

      Please contact if you have any questions.

      1. Great to see Bryton commenting on this page! As feedback to Bryton, I is a shame that that option was removed. I see why many would like to go through the Android app, but for me it is also important to upload routes and download/delete workout files from the device without going through any app or cloud, like you can do on Wahoos. Unlike watches, bike computers can have a proper USB port.

        That’s a deal-breaker for me.

  2. Hi. Did you tried to actually open any structured workout on the 420 device? I can import workouts to the app, but can’t start a workout with this set of intervals on the device. Manual says about train and test mode on the main menu, but there is no such option. I was using it very often on old 310e model…

    1. Hello Adrian, this feature is currently not available on the Rider 420 device. The on-device workout feature, similar to the Rider 310, will be released in a future update scheduled for later this month. This will automatically update through the Bryton Active app when it becomes available!

      1. Hi. Looking forward for this feature. It is 3rd May already and there is no updates for 420 🙁
        Where can I report issues with this device? After switching bikes in profile it won’t get GPS fix (reboot is needed).

  3. Is it possible now to enter sensors menu without stopping the ride? I owned Rider 310 and it was simply impossible to calibrate power meter after warm up or mid ride…

    1. HI. It is possible and seems to be working (power meter calibration for example). This can be done also in the mobile application. You can also change bike or load turn by turn track.

  4. can someone here please tell me, in which exact format(s) planned turn-by-turn bryton-active-app tours are saved on newer bryton devices (rider 420) and what exactly is the destination folder called?

      1. yes, please, if that is possible. unfortunately, i was not lucky and only received very superficial answers 🙁

        unfortunately, you can’t find any satisfactory answers on the net either, the only ever reference is the app or there is only totally outdated solutions to be found.

        those who don’t want to or simply can’t take the step towards the app are left out. from my point of view, this is not a good choice and trend.

        route planning + transfers should be realized in a much more easy way and without artificial obstacles or limitations. if i am not mistaken, the situation was far better with older devices?

        i’m sorry, but i’m really very frustrated….

        after all, it would be really fantastic if an arbitrary turn-by-turn route could be posted here for a better understanding.

        thank you very much.

        1. ok i’ve emailed them to answer this here. check back in a few days
          can you not just interrogate the device yourself to find out the answer after creating a new route? tbt format is relatively standard you could use fit file repair tools FFRT to look into the file and try different file format conversions of TBT

          1. here is the problem.i’m trying to convert a planned route from openrouteservice to the correct format (?) in an alternative way, because i don’t want to go through the whole registration process, logging in my device, installing the app on a suitable smartphone, uploading my routes – just all these strict dependencies.maybe this sounds exotic to your ears, but i think a lot of things could be simplified a lot more. by the way, this also applies to firmware updates. why can’t they just be downloaded os-independently and stored in a special folder on the device so to get initialized?i think that’s how it used to be, but now it’s all so much easier… 😉

          2. special folder: well, i made the same suggestion to hammerhead as another way to use dropbox to control upload of routes and structured workouts! so it doesn’t sound exotic! 😉
            use FFRT to convert it. that WILL work ($20 or something similar) and will create tbt instructions
            use as a site to curate your routes, that should mostly work as you load the files in. (free, or rwgps)

          3. thanks for the tip.however, my heart beats for linux and free opensource software, so i rather hope to be able to find a way to convert the gpx files (incl. instructions) created with openrouteservice into the correct turn-by-turn format of the rider 420, in order to finally be able to follow my own routes. this is the reason for raising this question here.for now, the device is doomed to record only…

          4. hopefully i didn’t alienate anyone with my freedom-loving point of view.i just wanted to note that i found a small script that can convert gpx routes from openrouteservice to the bryton compliant format, at least for the rider 330!the exported tour.gpx file is being converted (offline) into these 3 files, which need to be placed in the “tracks” folder:tour.tracktour.smytour.tinfounfortunately, the option “follow route” of my rider 420 still is empty. obviously, the formats changed for this model.anyone here with a rider 420, who can just take a look at what files are in the tracks folder after importing a tour with the bryton app?thanks a lot

          5. Hi, I was forced to connect my bryton 420 to my pc and look for these files.
            After placing route in fit folder in PlanTrip directory it can be converted by the device to some binary format used during the follow route option. This operation can take more than 10 minutes on longer routes.
            After this operation in Tracks folder 2 files will be created – smy and tinfo extensions together with separate directory which is named like the fit file. It looks like this directory contains some smaller pieces of map / track divided into some zones. Multiple zmap files name contains some numerical values, probably it could be some coordinates based system or grid similar to UTM zones. There is also one more file in this directory, named like the fit file with zinfo extension. znmap files are pretty small, so probably device is using it to display track when you follow route, only single zone/sector is loaded into the memory at a time.
            All these files seems to be binary, so if this format is not documented and well known then some extra work will be needed to convert fit / gpx into this format.
            You can find all these files for 3 tracks here

            Hope it helps,
            Keel well

          6. thanks a lot for your help, adrian.the first part seems the most interesting.if the rider 420 really does the conversion internally for .fit files in the plantrip folder on the device itself, a converter for openrouteservice tbt-.gpx to .fit files could already be the solution and there is no need to struggle with the bryton format at all.i am not very familiar with gps formats and offline converters for linux, unfortunately. i had a look at routevonverter and gpsbabel, but i did not get very you have a working suggestion for this so i can test?@tfk: thank you for your proposal, this is probably worth a try for windows users and a rider 420?

  5. I’m currently living in Indonesia and people here recommend Xoss and Bryton a lot. I used to use the “Xoss G+” but it broke after 3 months of use (you might want to check it out as it’s really good for the price).

    And so after reading this review I decided to save up and buy the Bryton 420. The Bryton just blows the Xoss right off the water! I couldn’t be happier! This is soo good for the price!

    Thanks for the great review! Time to enjoy my new gear haha

  6. Hi
    I got a bryton rider 420 and when I stop to eat something it goes off after 10min.
    Is there any way a can turn that option off?
    Anyone else got that problem?
    Thanks in advance
