San Diego offers a year-round 'Three Zone' mountain bike ecosystem that generic search results often conflate. You have **Coastal Canyons** (Los Peñasquitos, Tri-Canyons) which are flowy and fast but suffer from 'marine layer' grease in the mornings; **Inland Mesas** (Mission Trails, Black Mountain) which are technical, rocky, and brutally hot in summer; and **The Mountains** (Mount Laguna, Noble Canyon) which offer true alpine riding but require shuttles and are snow-bound in winter. Critically, the 'SGE-Killer' missing context is the **E-Bike Class Regulation Map**. While shops like Black Mountain Bicycles sell high-end e-MTBs, major trails like Noble Canyon (USFS land) and state parks often have strict Class 1 or total bans that aren't immediately visible on apps like Komoot. For serious riding, prioritize **SDMBA** status reports over tourist listicles, as trail closures due to 'mud' (rare but destructive to SD's clay soil) are aggressively enforced by rangers.
