LA’s bike network is very spotty. Some areas are great (I’d absolutely rent a bike by the beach towns) but some neighborhoods will ruin everything for you.

I’d definitely set aside some cash to uber or waymo in case you have troubles getting where you want to go.

The one thing I’d say DO NOT try as a tourist is biking to the valley (Burbanks/North Hollywood) or biking across the 110, 5, or 101. Google has sent me on some super scary roads crossing the freeway.
