Descending

A solid all-round descender (66° head angle, 140mm) — capable in the rough and steep without being an all-out bruiser.

EMTB Forums verdict
The 2022 Bulls Sonic EVO AM was the brand's full-power Bosch all-mountain line, built around a four-bar full-suspension frame on full 29in wheels. It is now discontinued. Note the wheel setup: the 2022 bikes run 29F / 29R, whereas the later 2023 Sonic EVO AM switched to a mullet (29F / 27.5R) layout, so the two model years are not interchangeable.
Travel runs 140mm on the alloy AM 1 and AM 1 750 (Bulls Lytro fork), stepping up to 150mm on the carbon AM 4 Carbon 750 with its RockShox Lyrik. Every trim uses the Bosch Performance Line CX (Gen 4, 85 Nm) motor. Batteries span a 500Wh PowerTube on the entry AM 1, a 625Wh pack on the non-Smart AM 2 Carbon, and the 750Wh Smart System (BES3, Kiox 300) on the 750-badged trims. The Smart System frames also sit slacker at 65 degrees versus 66 degrees on the non-Smart frames.
Value scales steeply: the alloy AM 1 opened at 4,787 euro, while the carbon flagship AM i Carbon with SRAM GX AXS, a Lyrik Ultimate and carbon DT Swiss wheels reached 9,917 euro. Bulls did not sell these at a genuine GBP RRP, so no sterling pricing is quoted here.
No owner or long-term ride data is captured for this dossier, so the notes above are limited to verified spec and geometry. The published Bulls geometry has a real stack quirk (it dips mid-range rather than rising monotonically) that carries across the trims and is genuine, not a data error.
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
Setting
Playfulness
58
A fair bit of pop, but happiest on flowing trail rather than trials moves.
Size balance
88
Rear-long with a planted front in L (FC:RC 1.73) — easy to weight the front and quick to turn, though it can feel light at the back at real speed.
Technical climbing
71
Climbs well — a 74° seat keeps the front planted. 600W of peak power and 85Nm of torque — a strong full-power motor.
No single standout trait — a balanced, versatile bike.
The numbers are well balanced for its category.
