If you ride a bike regularly for exercise the ride itself wouldn't be too extreme because the hills are not that steep for a fit cyclist, but for those of us who only ride in the flats it'd be a brutal ride over the hills. That said even if you're fit, the main roads that go over the hills are not particularly bicycle friendly because usually it's either cars sitting in traffic or cars driving aggressively because there's a break in the traffic or cars driving aggressively trying to beat the traffic. There are a few less-trafficked routes but those are windy with Waze drivers driving, you guessed it, aggressively. If you go west of the major LA hills to Topanga and above Malibu there is a vibrant weekend cyclist community that only has to deal with... aggressive drivers in fashionable cars out joy riding (I jest somewhat but that area is one of the most popular with serious and casual cyclists (lotta spandex up in that piece!)).
