10 of the best bike computers

A user-friendly bike computer enables you to collect vital ride stats and track your progress. Rob Banino tests and rates 10 of the best

Bontrager Trip 300/Duotrap S Combo 

£79.99 

Possibly the biggest thing the 17g Duotrap S speed and cadence sensor has going for it is that it could be the coolest-looking sensor on the market. Yet the Duotrap S only works with Trek frames that have the corresponding socket built into the chainstay. Fortunately, the 23g Trip 300 computer works on the Ant+ network so can be paired to a more conventional but less sleek speed sensor.

Setting up the 55 x 40mm Trip 300 is a breeze and it took only 3:01mins to band on the mount, calibrate the computer and pair it to the borrowed sensor. Its three buttons are big and have clearly defined modes. It only has basic functions (current, max and average speed, trip distance and time, clock, calories and temperature) but, if that’s all you need, is an attractive option.

Verdict: Supremely user-friendly but needs a Trek frame for combo pack to work 79%

Lezyne Super GPS

£159.99 

Attaching the mount and setting up the 74g Super GPS takes 4:37mins. That time is all the more impressive given that the device’s operating system is far from straightforward. It has four buttons that each serve two purposes, which can lead to a few wrong turns. Aside from the head-scratching set-up, the 75 x 50mm Super GPS is a decent computer. It works without sensors, tethers to GPS signals quickly and the screen is easy to read. It’s also Ant+ and Bluetooth enabled so will pair to similarly enabled heart rate and power monitors as well as your smartphone for mid-ride call, email and text notifications. That aluminium bezel gives it the classy look typical of products but it’s a full centimetre taller than any other unit here and stands a full 3cm above your bars.

Verdict: A little bulky with a baffling operating system but pretty good nonetheless 81%

SigmaSport Rox 5.0 

£119.99 

Much like the VDO M5, Sigma’s Rox 5.0 is an all-in bundle of data-gathering kit. Your 120 quid buys you a 60 x 55mm, 39g display and 7g mount, a 15g fork-mounted speed sensor, 16g cadence sensor, 55g heart-rate chest strap plus zip ties and rubber bands. Fitting the speed and cadence sensor took 1:36mins, and getting the display personalised, calibrated, fitted and synced to the sensors took another 3:42mins. Despite the various parts and the four buttons, the process is intuitive enough to muddle through without the instructions. On the bike, your current speed is centre with the biggest digits. Your cadence and heart rate readouts get the top corners while the bottom line is for everything else. The extended corner spurs make it easier to press the buttons.

Verdict: Lots of pieces and lots of buttons but a breeze to set up and use 77%

Specialized Speedzone Sport Wireless

£40 

The standout feature of the Speedzone Sport is its price – at £40 it’s half the price of its nearest rival here. That said, it is the most basic option, offering speed, distance and time data but nothing else. The 21g display is small (32 x 42mm) but its digits are big and easy to read, although you only ever get to see two metrics at a time, your current speed plus another. Two small buttons take care of configuration, and wheel size was selected and the time set in just one minute, with only a cursory glance at the instructions. It took 4mins to fit the sensor and magnet (27g combined), and mount (10g). However, you should add another minute or so as the 3mm bolt on the mount’s hinge had to be tightened during the test ride to stop it flapping about when going over bumps.

Verdict: Considering the price, there’s nothing to complain about – but it’s very basic 75%
