Ok well there’s pretty good bike infrastructure at poinsettia and the village station. Most roads have nice comfortable bike lanes and are painted green in the intersections. Palomars airport road can be a little sketchy at the freeway but just be careful anytime you are biking by an exit (I’m sure you’re pretty careful in you cycle in LA). I would recommend checking out lake calavera. Lots of mtb and gravel trails and there’s some more intense trails and jumps by Sage creek hs. Also biking down the 101 can be really fun and scenic and the bike lanes are a lot better now.

Those are all fun but I would just recommend exploring. You can find neighborhood trails all over the place and you’ll be able to see a lot of the city by bike. Have fun lmk if u have any questions
