Top value choice

BikeRadar score4/5

This top-quality, high-visibility downloadable wireless unit is great for drop or flat-bar bikes. The setup instruction Bible is ruthlessly efficient in typically Teutonic style so figuring it out is easy. The rock-solid sticky back mount will work with standard bars and flat bars if squashed, but won’t work with stems or top tubes.

The sensor fixes with a rubber band or zip ties, the clip-on magnet is super-tenacious, and everything has a really good-quality feel. Current speed and clock are clearly displayed so you won’t miss your tea. An easy to press bottom button scrolls the secondary menu of speed, double decimal-point distance and timer. Decent-sized digits and title bar keep you on track even when your blood sugar’s low.

Freelance Writer, UK
Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
