Slack 64° head angle, 170mm travel and a long 1273mm wheelbase — composed in the chunk, confident when it gets steep, and stable through fast corners.

EMTB Forums verdict
The all-new Decoy is YT's full-power gravity e-MTB, rebuilt around the Bosch Performance Line CX Gen 5 motor (100Nm, 750W peak) and an 800Wh PowerTube battery. It runs 180mm up front and 170mm out back through YT's V4L Horst-link suspension, an Ultra Modulus carbon frame and a mullet wheel setup with a 29in front and 27.5in rear. A flip chip at the shock mount switches between a Regular and a Low geometry setting.
Four builds span the range. The CORE 1 at GBP 5,999 pairs a Marzocchi Bomber Z fork and SRAM DB8 brakes with a Shimano Deore drivetrain. The CORE 2 at GBP 6,999 steps up to a RockShox Zeb Select+ and Vivid Select+ with SRAM Eagle 90 Transmission and TRP EVO PRO brakes. The CORE 3 at GBP 7,999 brings Ohlins RXF38 M.3 and TTX22 M.2 suspension with SRAM S1000 Transmission. The halo CORE 4 at GBP 8,999 runs FOX 38 Factory and X2 Factory, SRAM X0 Transmission, DT Swiss HXC 1500 carbon wheels and SRAM Maven Silver brakes on HS2 rotors, with a claimed weight of 23.2kg.
Geometry read
What the numbers mean on the trail
Computed from this bike's geometry, spec and build kit — reach, wheelbase, chainstay, head and seat angles, travel, motor, weight and the fork/tyre/brake spec — and worked out per size, because a fixed chainstay can make an S and an XL feel very different.
Size
Playfulness
40
More planted than poppy — better on steep terrain than tight, fiddly singletrack.
Size balance
82
Balanced front-to-rear in L (FC:RC 1.86) — weight sits evenly between the wheels.
Technical climbing
77
Bosch Performance Line CX Gen 5 and a steep 78.1° seat angle keep the weight planted over the front — a proper winch. 750W of peak power and 120Nm of torque — among the most powerful e-bike motors made.
Rewards commitment; it should feel calmer as the speed rises.
The numbers are well balanced for its category.

⚙️ Adjustable geometry: this frame has a high/low setting — low drops the BB and slackens the head angle for more descending stability; high lifts the BB and steepens slightly for clearance and a perkier, more playful feel.
Computed from geometry + spec, not a paid review. Scores are guidance, not gospel.
