Get the info from your ride from as little £5

If you want to know how fast you're going and how far you've been, you need a cycle computer, a sm​all electronic widget that sits on your handlebars and measures your progress. You can get a surprising amount of performance for your money.

How much you pay for a cycling computer depends on the functions you want. You'll pay more for a wireless sensor than for one connected to the head unit by wires, for example, and still more if you want functions like a heart rate monitor, cadence sensor of ability to pair with a smartphone.

We've found the best deals on cycle computers in a range of categories, from brands with good reputations for reliability and usability. Before you wade in, though, you might want to read our general guide to cycle computers.

Basic computers

You can get basic computers from manufacturers you've never heard of for as little as £3 from Amazon, but on the rare occasions they have reviews, they're not exactly rapturous. Our selections are a little more conservative.

B'Twin 100 — £7.99

French sport superstore chain Decathlon is always worth a look for a bargain, You only get five functions in this minimal unit — speed, average soeed, trip distance, total distance and clock — but for just eight quid what more do you want, or really need?

CatEye Velo 5 — £12.00

Just over a tenner gets you this nifty little five-function unit from CatEye. It's supposed to be £14.99, but CRC has it at the price above, and CatEye's reputation for reliability makes it a good deal at that price.

It's a wired unit and tells you speed, maximum speed, trip distance. odometer and time. It comes with a universal mount but the cable is only long enough to reach the front wheel.

CatEye Velo 9 — £11.95

If you want a few more functions and a bigger screen with more data, another few quid gets you this CatEye model. You get a stopwatch as well as a clock, and it'll attempt to work out how many calories you've burned. That's really only useful for comparing the amount of work you've done between rides; don't hit McDonald's hard just because it says you'd burned off the equivalent of three Big Macs.

Wireless computers

B'Twin 500 — £19.99

B'Twin 500

For just £20 this is one of the cheaper wireless computers we've found from a significant brand (though if you're really strapped, the B'Twin 120 is even cheaper at £12.99). It has a big display, with a backlight, and features include average and maximum speed, trip and total distance, clock, stopwatch and speed comparison against the average so far.

Cateye Velo Wireless — £22.90

We've chosen a lot of CatEye computers in this selection because they're widely available, reliable and easy to use. The Velo Wireless is the company's cheapest wireless computer but gets solidly positive reviews.

In effect, it's the wireless version of the Velo 9, though it lacks that unit's calorie guesstimate function.

Cateye Strada Slim — £35.95

If you want something a bit more posh, the skinny version of CatEye's Strada computer is available heavily discounted. It has a bigger screen than the old Strada, and a comes with a slimline sensor so it's less obtrusive on your bike. 

As well as a full range of functions, it has a second trip distance meter, so you can, say, measure intermediate sections of a long ride.

Heart rate computers

Rolson 22-function heart rate computer — £19.99

Cheap computers that also tell you your heart rate are rare, but this super-cheap unit from Argos is probably worth a punt.

You get your usual computer functions, plus current and average heart rate and it even gives an estimate of how many Calories you've burned.

Ciclosport Ciclomaster CM 4.4A HR — £61.62


Okay, we have to admit a bit over 60 quid isn't exactly cheap, but the Ciclosport CM4.41A is the least expensive computer we've found that gives you both a heart rate monitor and an altimeter.

There's a decent suite of heart rate functions too, including target zones and heart rate-based Calorie consumption.

GPS computers

Computers that can use the Global Positioning System to find your precise location, and speed without wheel sensors can now be found for under £50 if you shop around. We've saved you the trouble.

Memory Map 250 — £43.61

For this price we don't expect it to be amazing, but Memory Map's base model on-bike GPS is a bargain if what you want is a simple bike computer and data recorder without bells or whistles. If very long rides are your thing, it'll go 28 hours.

If you have multiple bikes, a big advantage of GPS computers is that you can swap them from one to another without faffing changing set-up.

Sigma Sport Pure GPS — £48.09

Sigma Pure GPS

An excellent price for a modern ride-recording GPS with a barometric altimeter and a nice big clear display.

Kalenji Onmove 220 GPS Watch — £59.99


This GPS watch from French sport store giant Decathlon provides a basic set of GPS functions, works with a Bluetooth Smart heart rate strap (Decathlon's is £27.99), communicates with your Android or iOS phone and outputs GPX files so you can upload to Strava or your other favourite activity website.

If you're one of those strange multi-sport types, you can use it for running too.

Road.cc buyer's guides are maintained and updated by John Stevenson. Email John with comments, corrections or queries.

Our official grumpy Northerner, John has been riding bikes for over 30 years since discovering as an uncoordinated teen that a sport could be fun if it didn't require you to catch a ball or get in the way of a hulking prop forward.

Road touring was followed by mountain biking and a career racing in the mud that was as brief as it was unsuccessful.

Somewhere along the line came the discovery that he could string a few words together, followed by the even more remarkable discovery that people were mug enough to pay for this rather than expecting him to do an honest day's work. He's pretty certain he's worked for even more bike publications than Mat Brett.

The inevitable 30-something MAMIL transition saw him shift to skinny tyres and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.

So none of these has cadence John?
On balance, I think I'd prefer a computer without speed to a computer without cadence, just as long as it also accumulates distance.

Aldi have a cadence and speed sensor for sale for £20, in shops on Sunday, but can order online now.  Not a full computer, but uses your Smartphone.

Think I've got a Cateye Strada Slim on most of my bikes - great for basic, at-a-glance info.

I then have Strava on my phone in a pocket.

biketime [37 posts] 11 months ago

I'll use my aging Cateye wireless with its manual on-off function forever. I HATE to see the clock rolling when I'm at 1-3 mph at a red light!

I've had the Btwin 500 computer. It uses a hub mounted speed transmitter, no wheel magnet. It's great. I don't think it's Bluetooth or Ant+ though.

I say 'had' as the Garmin-like twist mount bracket is so weak the computer bounces out at the slightest bump or knock. Mine lasted about 3 weeks before it bounced out somewhere near a Lancashire reservoir, never to be seen again. If they fix that, it'd be a great little computer.
