Decoy MX 2026

The Decoy MX is YT's gravity-leaning mullet e-MTB, built around a carbon frame with 170mm up front and 165mm out back, a Shimano EP801 motor (85Nm, 600W peak) and a custom 720Wh battery on the Core 5 and Core 3. It runs a 29in front and 27.5in rear wheel and a flip chip that swings the head angle between 65 and 64.5 degrees, the seat angle between 76 and 75.5 degrees, and the BB height between 352mm and 344mm.

Across the three trims the value picture is clear. The Core 1 at £4,999 drops to the lower-output Shimano EP6 motor and a 540Wh battery with a RockShox Domain fork and SRAM DB8 brakes, so it is the heavier, less powerful entry point. The Core 3 at £5,999 steps up to the full EP801 and 720Wh pack with a Fox 38 Performance fork, DHX coil shock and Shimano SLX. The £7,999 Core 5 is the halo build: Fox Factory 38 and Float X2, Shimano XT Di2 with FREE SHIFT, SRAM Code RSC brakes and Crankbrothers Synthesis wheels on Industry Nine hubs.

Geometry sits on the conservative side for an enduro bike of this era. The four-size range runs medium to XXL, but the reach figures of 429 to 489mm are closer to what other brands label small to extra-large, so size up if you want length. Chainstays are a fixed 442mm across all sizes, and the seat angle is on the slacker side, which favours descending composure over steep, technical climbing. Note that the Shimano-powered Decoy MX has now been superseded by YT's Avinox M2S-powered Decoy X, so the MX is best viewed as a run-out or used buy.
