Idaten Jump

Sho Yamato is a young mountain biker who loves racing at the "X-Zone," a training course filled with cherished memories of his late father. While defending the course in a challenge against the arrogant Shark Tooth team, a mysterious black smoke suddenly envelops the track and transports Sho, his friends Kakeru and Makoto, and his mountain bike "Flame Kaiser" to an alternate realm also known as the X-Zone. In this world, all conflicts are resolved through high-octane mountain biking contests called "Idaten Battles." To earn his ticket back to the human world, Sho must take on formidable rivals across perilous courses—from active volcanoes and ancient ruins to scorching deserts and frozen peaks—and gather all 10 sacred gold emblems.
