The bike is powered by a 250W drive unit and a DMEGC 417.6Wh battery, complemented by a 36V 2A charger and a compact 1.47-inch LCD display. Its drivetrain includes a SHIMANO TY300D rear derailleur, SHIMANO M315 shifters, a KMC Z7 chain, an aluminium alloy 52T crank, and a 7-speed (14-28T) rear cog setup, all enhanced by a Mivice S200 torque sensor for efficient power delivery. For braking, the X 2025 is equipped with TEKTRO HM-M275 hydraulic disc brakes and matching brake levers, ensuring strong stopping power. Rolling on 20×1.95-inch CST tires mounted on aluminium alloy double-layer rims with stainless steel spokes and brass nipples, it offers both durability and comfort. The cockpit features an aluminium alloy handlebar (560mm length), an alloy stem, TPR non-slip grips, and a VELO vacuum full-fit saddle mounted on an aluminium alloy battery seatpost, making it a balanced combination of performance, convenience, and style.
