Dense, hilly, wet when the fog is in, and full of parking garages where a battery dies quietly. SF is the easiest place in the Bay to be ten minutes from another rider — and the hardest to get a tow truck to in under two hours.
Live from the app. Helpers are riders who said they'd stop for a rider nearby — not vetted, not on call, not a service.
Every request that ended with a rider helping a rider. No names unless the helper chose to be named; never a location.
The app pings riders by where you are. If you can't post, nobody gets pinged — so know where the signal drops before you need it.
Hurt, or anyone else hurt? Call 911 first. The app pings riders, not an ambulance. For a bike you can't ride and nobody can fix at the roadside, the breakdown guide covers tows, insurance roadside, and what to do while you wait.
The meter at the top is the number of riders in San Francisco who said they'd stop. When it reaches 40, a rider stuck anywhere in the region is usually within a few miles of someone. The riders you bring are the ones who'll be nearest when it's your turn.
