Bryton Rider 40E GPS Cycle Computer



Impressive training and data recording package let down a bit by poor instructions and clunky user interface

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Bryton have been increasing their product range in a bid to grab some more of the GPS market. Will the feature packed Rider 40E have enough to take on Garmin's dominance though?

The Rider 40E sits smack in the middle of Taiwanese company Bryton's range of cycling specific computers and priced at £149.99 its competitive for an ANT+ unit that'll work with power, heart rate and cadence. For an extra seventy quid you can buy the 40T version which comes with a heart rate strap and speed/cadence duo sensor making it ideal for use on the turbo. Bear in mind these are RRPs; I've seen them online with as much as 30% off.

With GPS computers getting bigger and bigger to cram in more features the first noticeable thing is how small the main unit is. At just 45mm x 69mm and a depth of 17mm it takes up hardly any bar/stem space at all.

The initial set up process is hampered by some pretty poor instructions in the box and they aren't a lot better online but if you've set up a GPS computer before you'll be able to blag your way through it. It's the usual stuff, few rider details, language, what data you want to see etc though you soon notice how slow button pressing is compared to a touchscreen.

Information is displayed on up to three different screens depending on how much you want to view while riding and what you're happy to analyse later. Splitting the screen into six segments means you can choose eighteen data fields from speed, power, HR, cadence, distance and time all of which have current/average/maximum etc options available. You've also got altitude, temperature and a calorie counter which gives results based on your information and heart rate.

In use the 40E is a bit slow to get a satellite fix initially but once locked on it showed little sign of losing it even in built up areas or under tree cover. The unit itself picks up movement very quickly from then on, with use in time trials using the autostop function only showing a one second slower time than the official timekeeper's watch.

While we are on the subject of time trials this was the one place that I struggled with the 40E due to the amount of data I wanted to keep an eye on. I wanted to see current and average power, speed and heart rate plus time of day, ride time etc. I had it spread all that over multiple screens making it hard to find what I was looking at with a quick glance. The text ended up small and abbreviated as the unit automatically scrolled through the pages.

On the road bike, using it as more of a data recorder than a realtime display and with just a couple of data fields on show, it was much more user friendly.

As an aside to the data recording side there is also a selection of preloaded programs. Four of them measure either functional threshold power; maximum heart rate; lactate threshold heart rate; and maximum aerobic power, all of which are really useful if you are following a dedicated training program on your own or with a coach. On screen instructions and audible cues help you follow them even though you're working at your limits.

You'll also find a range of different training rides from easy recovery through to full on intervals. I found them all pretty handy to use whether on the turbo or on the road and it was easy just to click a couple of buttons and get going.

Uploading your ride information is relatively hassle free once you've downloaded the Bryton Bridge software to speak to the device. You can upload it to the Brytonsport webpage which is similar to Garmin Connect allowing plenty of analysis of your ride plus an ongoing record of daily metrics and overall distances.

Strava has never really bonded with Bryton mostly due to the fact their devices store the ride files as .bdx (Bryton Data Exchange) format which doesn't fit in with Strava's requirement for .tcx, .fit or .gpx. Using the Bryton Bridge software you can either upload it to Brytonsport and transfer it across to Strava or save it to your computer as one of the compatible file types and upload from there. Either way it's an extra step you have to go through that you don't with Garmin.

On the whole the Bryton Rider 40E is a decent bit of kit especially at the discounted prices with the training and data recording possibilities. Everything I wanted it to do it could. The only thing you are really sacrificing is mapping but for that you would have to at least double the screen size to accommodate them.

Over the test period it never once dropped connection to any of the ANT+ devices or lost the satellite signal so every ride I uploaded to Brytonsport was uncorrupted. The 30 hour battery length also gets a massive thumbs up, it hit that consistently in the warm temperatures of summer and means it would be a good choice for long distance rides.

Saying all that though the user friendliness lets it down a little especially when used alongside one of Garmin's offerings; the 40E just feels a little clunky and unpolished. Its not a major concern unless you have to do a lot of button pushing and setting up while you ride. The main problem is that although the mount is really secure the o-rings let the unit twist a little when you are pushing the buttons, a switch to a Raceware mount improved things no end.

Rate the product for quality of construction:

Well put together with a solid feel to it, the 40E showed no issues with heavy rain or high temperatures.

Rate the product for performance:

Considering the price and small package the Bryton comes with plenty of tools and tricks which means it more than just a ride logger. Yeah it's not the smoothest to operate but I think that is a secondary concern to what you get back from it.

Rate the product for durability:

Battery life is good as are the dust and waterproofing. It's been dropped a couple of times with no signs of any damage.

Rate the product for weight, if applicable:

Just 56g is a minmal weight addition to your bike.

Rate the product for value:

A touch pricey at the full RRP in my opinion but at the discounted prices at just over a £100 I think its a good investment. The prices do seem to fluctuate quite a bit day to day so its worth keeping an eye on the web.

Tell us how the product performed overall when used for its designed purpose

I liked using the 40E even with the small issues with usability. Its not that it's awkward to use it's just that the latest model Garmins I have to compare it to have become very smooth to use. As far as recording data goes and making sense of it through, Brytonsport it can't be faulted.

Tell us what you particularly liked about the product

The small size and the training sessions.

Tell us what you particularly disliked about the product

Clunky feel.

Did you enjoy using the product? Yes.

Would you consider buying the product? Yes.

Would you recommend the product to a friend? Yes.

Anything further to say about the product in conclusion?

The overall score of 8/10 might come as a bit of a surprise after I've criticised the user interface and clunky feel but that really is only a small niggle. If you are a data nerd there is very little that the 40E can't give you especially from a ride analysis point of view using the dedicated software. Shop around and get yourself a bargain.

is it compatible with garmin mount ?

I've got a Bryton 40, it does fit, but it's a bit tighter than using the correct one. I think the lugs are slightly deeper on the Bryton.

Maybe off topic, because I am not going to talk about this specific computer, but frankly bicycle computers - every single one that I have bought and used - annoy the hell out of me by spontaneously resetting themselves, especially the measured trip distance, which always seems to happen when it is data that I need.

You would have thought that in this day and age, when computers are in literally everything, then we would have bicycle computers that are a little bit better than a fancy digital watch and are not prone to the same issues that have existed in them ever since the first bike computers turned up.  2

I have a bryton ryder20 and one thing that's lacking that wasn't mentioned is there's no auto pause, I have to remember to do it myself which I sometimes forget. If they had that on this one that would be a great improvement. The compact size is handy but yes the instructions for the ryder20 were vague as well. Took some getting used to, yes there is a lot of button pushing but for something between a standard cycle computer and GPS device that's more like a sat-nav it's not a bad gadget  16

I think I'd prefer an Etrex 20 for that price. You can do more than just cycle with it.
