A GPS bike computer shows speed, distance, climbing and a route on the handlebar, so you can keep your phone in a pocket. The differences are screen size, touch or button control, how maps and turn prompts work, and how many hours the battery is listed to last.
The six units below include two Garmin models, two Wahoo models, an iGPSPORT and a COOSPO. Specs come from each product’s listing page. We have not used these devices ourselves, and battery and accuracy claims are the makers’ own.

Buttons or touch?
Buttons are easier with gloves. Touch is quicker for panning a map. The Wahoo ROAM V3 and iGPSPORT BSC500 offer both.

For setup, route sync and notifications, yes. Recording a ride works from the unit itself.
