Bike computers and power meters
You’ll find GPS bike computers and simpler speedometers, spider-based power meters and heart rate sensors. Most devices connect via Bluetooth and ANT+. What matters most when choosing is the data you want to track and whether you need navigation.
Bike computers and power meters
The core of the range is GPS bike computers with 2 to 2.9″ screens. Some models offer map navigation, a colour touchscreen and sensor pairing via Bluetooth and ANT+. A few also measure altitude or temperature. Battery life is 10 to 40 hours according to the manufacturer, and most models are rated IPX5 to IPX7.
For training with watts there are spider-based power meters, sold on their own or in sets with cranks. The cranks are carbon or aluminium, 155 to 175 mm long and mostly with a 24 mm axle. Some sets include 50/34, 52/36 or 53/39-tooth chainrings. Data is sent via ANT+ and Bluetooth to a bike computer, watch or app.
Rounding off the range are heart rate sensors: chest straps and an optical armband. The chest straps are mostly rated IP67 or IPX7 and, according to the manufacturer, last up to 1000 hours on one battery. Before buying, check that your bike computer supports the same protocol as the sensors you want to pair.
How we rank results
We determine the order of offers in search results and in category listings automatically, according to the rules below. No seller is given priority in the ranking, and it is not possible to pay us for a better position.
Search (default sorting “Relevance”): we show offers that match the search term, including those with a small deviation or only a partial match. Their order depends most on how popular the offer is with customers. If you have accepted cookies, the next biggest factor is which categories and offer attributes you have viewed during your current visit. It also matters how popular the offer is for that search term, how closely it matches the term and how popular its category is for that term.
Categories (default sorting “Best Sellers”): the offers that sell the most appear at the top.
Sorting by price: if you choose Price: Low to High or Price: High to Low, we sort by price including VAT only.
