Lezyne Mega XL GPS.
The longest GPS battery life in the roundup with a crisp black-and-white display readable in any lighting at an accessible $199 price point.
The Verdict.
Gavler Meta-Score
“The Mega XL GPS is for riders who want a reliable data recorder with unprecedented battery life at an accessible price. 48 hours of GPS means you can ride all week without charging, and the monochrome display is readable in conditions that wash out color screens. It's not a navigation device — it's a recording device. And it does that job better than anything else available.”
