Polar V650



The Polar V650 is a bike GPS with an industry leading storage capacity and incredibly user-friendly interface. It is missing some advanced navigation features, like turn-by-turn navigation, but it tracks all the basics, is ANT+ sensor compatible and comes with preloaded detailed maps.

Pros: With up to 10,000 hours of data storage, this bike computer is second-to-none in memory capacity, which is great for those training and working to beat personal records. Its interface is one of the most intuitive of any cycling GPS we reviewed, and the entire device is overall a user-friendly bike computer.

Cons: This Polar GPS device is missing a few nice features: turn-by-turn navigation, live GPS tracking and smartphone notifications. It’s also on the heavier side at 4.2oz, though it also has a larger screen than many other models. One of the biggest downsides is its 10-hour battery life, which is the lowest capacities of any other model we tested.

Bottom Line: The Polar V650’s storage capacity blows away the competition, but its dismal battery life—and the lack of some navigation features—may make its memory irrelevant to some marathon riders.

Best for: A first-time bike GPS, shorter rides, training and improving on previous rides
