10 features that would improve next-generation GPS bike computers

With Garmin set to introduce new solar-charging models very soon, what other features would we like to see?

News that Garmin is set to introduce solar-powered Edge 540 and 840 bike computers got us thinking about what else we’d like to see offered by next-generation GPS bike computers, and here are 10 features we think would improve the experience.

> Secret new tech! Garmin set to release solar-powered Edge 540 and 840 bike computers

More solar charging, please

We'll start with solar charging because we think this is just about to take a big step forward. Charging up the phone, laptop, smartwatch, groupset, power meter, and whatever other gadgets we’re using is a part of life for most of us these days – hardly the most arduous of jobs but a pain in the ass when you forget.

It would be handy if we needed to recharge the bike computer less frequently. Running out of juice mid-ride is annoying, especially if you’re following a route at the time, and longer run times are particularly useful for those on multi-day epics too.

Garmin introduced the Edge 1040 Solar bike computer last year, borrowing tech from its smartwatches. reviewer George Hill said, “I used the Garmin Edge 1040 Solar on a two-hour gravel ride on a gloriously clear day and by the end, my total battery consumption was just 4%. In a month of testing, I have only ‘had’ to charge it once, and even then it was at 20%.”

The downside is that the Edge 1040 Solar is £629.99, over £100 more expensive than its standard Edge 1040, so there's a hefty price for the added convenience. Most of us aren’t going to spend that amount on a bike computer

That’s why it’s such good news that it looks like Garmin is just about to update the Edge 530 to become the Edge 540, and the Edge 830 to become the Edge 840, and each of them will be available in a solar-charged version.

We think the Garmin Edge 540 Solar will be US$449.99, so it’s likely to be around £399.99 in the UK (but don’t quote us on that).

Garmin is still the market leader in bike computers and other brands are bound to follow. We’d expect to see loads more solar-powered models launched over the next couple of years.

Give us better re-routing

“When do we get AI rerouting, because rerouting is rubbish on basically any bike computer ever?” asks Dave Atkinson.

You know all about re-routing, right? You’re following a route and you accidentally miss a turning, or the road is closed, or whatever.

In an ideal world, your computer instantly comes up with an adjusted route to get you back on track and, to be fair, that’s often how it works. But have you ever had your computer angrily beep and flash to tell you that you’ve gone off course, but steadfastly refused to come up with another route? Or has it ever given up on your original route and taken you on an entirely different – and worse – route? Or has it tried to take you on a gravel track when you’re on your best road bike with skinny tyres?

Re-routing has come on a lot – the Garmin Edge 1040 is better than previous models in this respect, for example – but it’s not there yet, and until it’s completely reliable a lot of people are reluctant to use it at all.

Use all that tech to improve safety

Bryton has just unveiled a new Gardia R300L bike radar tail light that can detect traffic approaching from the rear and communicate the info to a compatible bike computer, and Garmin has had its Varia system for a few years, but bike computers don’t usually do a whole lot to improve your safety.

At last year’s Sea Otter Classic we spoke to a company called Spoke that’s trying to improve road safety by providing riders and drivers with hardware and software that provides real-time data about hazards through the use of wireless vehicle-to-everything (V2X) technology.2022 Sea Otter Spoke - 1 (2)

V2X is communication between a vehicle and anything it may affect, such as other road users. Spoke says it’s providing the first connected IoT [Internet of things] ecosystem “to offer secure, direct communication for contextual awareness and alerts between drivers and riders, enhancing safety for all road users”.

The tech is intended to tell riders when vehicles are approaching from behind, as well as to provide alerts when car doors are open or when vehicles are leaving parking spots.

It can provide a car driver who is indicating with an alert that a nearby bike rider is likely to pass on the inside, for instance, although there are loads of other situations that could be highlighted.

Spoke plans “to provide dedicated hardware and software to unlock C-V2X communication to the most vulnerable road users” – including cyclists. A car’s C-V2X system communicates directly with the Spoke system added to a bike; it doesn’t go via satellite so does not require network coverage.2022 Sea Otter Spoke - 2

Pie in the sky? Well, this isn’t the sort of tech that’s going to be added to a normal bike computer any time soon. For a start, the brains of the operation is contained in a small black box that’s fixed to the bike – possibly under the bottle cage – or carried in the rider’s pocket. Long-term, though? Watch this space.

Give us a bell!

A simple suggestion. A bike computer is already capable of sounding alerts, surely adding volume so that it can act as a good old-fashioned bell wouldn’t be too difficult.

“I sometimes used to stop/start my Wahoo on the cycle path to try to encourage dog walkers with a very wide stance to move aside – just a more subtle alert of presence than a big cough,” says editor Jack Sexty.

Press once for a polite ping. Press twice for foghorn mode.

Do we need computer-controlled automatic signalling?

We’re not saying that automatic signalling is something we’ve ever thought of before, but it is happening.

A Chinese company called Mei Lan has introduced a smart rear light called the Cute Eye – maybe it sounds better in Mandarin – that features amber turn indicators. 

2023 Meilan - 1

As you’d expect, you can control the indicators via a Bluetooth remote on the handlebar, but when paired with Mei Lan’s GPS-enabled e-bike display in navigation mode – which is in turn paired to an app on your smartphone – the Cute Eye will automatically signal left and right turns along your planned route.

One possible worry is that you’ll confuse other road users if you’re not focused on your navigation and miss a turning.

What do you think, a good idea or not?

Lose the bezel!

Loads of people have mentioned to us that they’d like to see bike computers lose the bezel – the area on the front of a device that isn’t the screen – and have a larger screen.

2022 Garmin Edge 830 - 1.jpg forum user mpdouglas says, “Take the active screen area to the edges of the device. Why are such large expanses of black border acceptable in this day and age? What's the point of mapping functionality if you need to get a pair of reading glasses out to see anything? Borderless screens have been a thing on every other gadget type for years… There’s a reason so many people choose to mount their smartphone to the handlebars.”

A front of a touchscreen Garmin Edge 830 measures 82mm x 50mm, for instance. The screen is 52mm x 40mm, not much more than half the area. Contrast that with a modern smartphone where virtually the whole of the front is screen space.

We realise that achieving something like this is more difficult than just asking for it, but come on! Large bezels are so last decade! Let’s have some full-width screens, please.

Let's have increased light integration

You can control some lights with certain bike computers but we’d like to see an increased level of integration.

2022 Garmin Varia RCT715 - unit.jpg

You can link a Garmin Varia Radar Taillight to a Gamin Edge computer and various other compatible computers, for instance. This not only allows you to receive radar alerts on your computer warning of approaching vehicles, but you can also control the light modes through the computer itself instead of pressing the button on the Varia. That’s handy for a rear light.

wahoo varia

Bontrager RT series lights can also be paired with and controlled by some Garmin Edge cycling computers and Lezyne has a system that allows you to control its LED bike lights via one of its bike computers.  

We’d like to see light integration from more brands and increased cross-compatibility – bike computers working with lights from multiple brands.

Enhance Predictive Path Technology

Hammerhead rolled out its Predictive Path Technology last year which allows the use of its Climber facility on all rides, even if you’re not following a route.

Hammerhead now shows upcoming climb elevation without a pre-loaded routeIf that’s gobbledygook to you, this essentially mean that when you’re out on a ride a Hammerhead Karoo 2 computer can anticipate and identify upcoming climbs. It gives you a detailed look at the elevation so you can gauge your effort… or even bail out and take a different route if you’re not up for it.2022 Hammerhead Predictive Path Technology_route2

Climb-specific data screens or overlays with colour-coded elevation profiles are available on Garmin and Bryton cycle computers too.

> Which GPS cycle computer is best for climbing? Garmin v Hammerhead v Bryton 

We were pleased when Jess Braun, Hammerhead’s VP of Product, told us in a recent feature on, “We’ll be pushing the bounds of Predictive Path Technology and bringing more things contextually to the rider that they maybe didn’t know about or didn't plan for, right as they're riding. We have this algorithm now that has some sense of what you might do, and giving you information around it.”

What, will that be? It doesn’t need to be limited to climbing information. It could offer info on descents, maybe suggest you switch to a particularly popular route or avoid certain features, or point you towards nearby amenities. It’s intriguing.

Introduce a greater level of standardisation

It's an old gripe but can we just have one type of charger/charging port, please? Most brands have now opted USB-C so it would be cool if everyone else could come in line. Cheers.

> Dear bike tech brands who insist on crazy proprietary chargers and cables: here’s a better solution 

2021 Prime Race Computer Mount 2.jpg

And while we're about it, computer mounts. It's another ancient moan. Most brands use a quarter-turn system... but they don't all use the same quarter-turn system. If you buy an aftermarket computer mount – or one comes with your bike – it'll probably come with different bolt-in ‘puck’ inserts to fit different computers.

Is this a good use of the world’s resources? No. Will this ever change? Probably not.

Bring back the integrated camera – it never really got going

It’s five years since Xplova introduced the X5 Evo GPS bike computer which featured an action camera. Maybe it’s time for someone to pick up that torch again.

Okay, we’ll admit the fact that the X5 Evo GPS did exist and doesn't anymore might suggest that it wasn’t an idea that took the world by storm. Fair point. However, the camera market has come on since 2018.

Our man Dave Atkinson wants a bike computer that features:

  • A camera that’s always recording.
  • An ultrasonic sensor measuring the distance to objects on your right.
  • You set a minimum passing distance in the GPS and when things are too close it saves the footage.

He’s offering bonus points if you can pair a rear-facing camera and extra bonus points if it overlays the passing distance. Simple, then!

What features would you like to see introduced to GPS bike computers, maybe next generation, maybe further down the line? Let us know below.
