Spiegel Online, a massive German media outlet, included the San Quentin 3 as part of their Eurobike coverage. Here's the translated copy, mildly edited:

"Slack headtube angle, short stem, long top tube. These are features that make up modern, full-suspension trail mountain bikes. Only those are often too expensive for beginners. For those who are looking for a bike for maximum fun and easy handling, Marin has transferred the concept to the hardtail. The San Quentin rolls stable on fast tires on wide tires (27.5 x 2.6 inches) and is stable in the air during jumps. All for 849€. For 1249€ there are two more gears and the necessary dropper seat post."
