브롬톤 12단 업힐(오르막) 능력 테스트 및 브롬톤 12단 실 주행 리뷰 입니다!

I tested the Brompton P-Line 12-speed bike's uphill capabilities. This is a real-world ride...uphill performance, a brief review of the Brompton 12-speed, and what to consider when buying... For those wondering whether to get a 4-speed or a 12-speed, this might be helpful!
