Join the Northern Secret Cycling Club as they take on the classic 'Yulao Grand Slam (Modified)' route, starting from Daxi and advancing along the Northern Cross-Island Highway to Luofu. Among the group, a surprising sight appears—a rider on a yellow UBike 1.0, whose incredible leg power keeps pace with the road bike team, becoming the most eye-catching highlight of the entire trip. The route then turns onto Yufeng Road, delving into quiet mountain paths to tackle a hidden, mysterious ultra-steep slope, and faces a major physical test on the continuous long climbs from Yufeng to Yulao. Upon reaching the Yulao Observation Deck, a magnificent sea of clouds rolls in, but an unexpected and thrilling incident on the return journey leaves everyone on edge.
