How many studies support Cycling?

Direct evidence specifically on cycling is comparatively limited: a systematic review reports associations between commuter cycling and lower all-cause and cancer mortality, and a long-running Swedish women's cohort found cycling-test fitness in midlife linked to lower dementia risk decades later. That's backed by 4 published studies in Vitaebase's database, including 1 meta-analysis, the most recent from 2021 -- a modest but real research base.
