This mountain range is one of the best cycling locations in southern California. With over 30 climbs, perfect year-round cycling weather (besides the occasional snowfall at higher elevations!), and it's proximity to the LA area, this is an extremely popular cycling destination.
Ecologically, the San Gabriels have a mix of climates. The southern and eastern parts of the range is high alpine, and as you ride north or west you'll shift into a completely desert climate - often on the same ride, due to the small size of the range. Unlike most big mountain ranges, the weather is more or less constant throughout the year, with typical southern California sunny skies. Because of this, it may be easy to underestimate this mountain range, but it qualifies as a major one, spanning 63 miles across and including several peaks above 9,000 feet.
Technically the hardest climb in the area is Mt. Baldy (to the Notch), but after attempting it ourselves, left it off the list because it's not rideable on road tires (gravel ok!)
