YT DECOY MX CORE 1 Bosch CX Gen5 800Wh Midnight White

YT DECOY CORE 1 — Entry-Level, Fully Loaded

The CORE 1 redefines what an entry-level eMTB can be. Featuring the same carbon frame, Bosch Smart System, and 180/170mm travel as its higher-end siblings, this build is anything but basic. Marzocchi’s Bomber Z fork and Bomber Air shock deliver plush, easy-to-tune suspension. Shimano Deore 12-speed shifting, WTB alloy wheels, and SRAM DB8 brakes provide solid performance for new riders or budget-conscious thrill seekers. It’s the perfect gateway to the DECOY family — capable, confidence-inspiring, and ready to rip.
