Bulls Sonic EVO TR 2022

The 2022 Bulls Sonic EVO TR was the short-travel trail member of the Sonic EVO family, sitting below the 140 to 150mm Sonic EVO AM and the 160mm Sonic EVO EN. It runs 120mm of travel front and rear on a four-bar layout, in either an aluminium or a carbon frame, with full-power Bosch assistance. It is now discontinued and was succeeded by the 2023 Sonic EVO TR.Every trim uses the Bosch Performance Line CX (Gen 4, 85 Nm) motor. The range splits across batteries and displays: the alloy TR 1 and TR 1 XS carry a 500Wh PowerTube with a Purion display, the carbon TR 2 steps up to 625Wh, and the 750-badged trims (the alloy TR 1 750, plus the carbon TR 3 Carbon 750 and the SRAM AXS-equipped TR-I Carbon 750) move to the Bosch Smart System with a 750Wh pack and a Kiox 300 sold separately. The Smart System frames also sit slightly slacker and longer than the non-Smart alloy TR 1.Pricing climbs from 4,787 euro for the alloy TR 1 to 7,637 euro for the carbon TR-I Carbon 750 with SRAM GX AXS, TRP brakes and DT Swiss wheels. A dedicated TR 1 XS build on smaller 27.5in wheels covers shorter riders with a steeper, more compact frame. Bulls is a German ZEG-group brand and 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. Worth noting the chainstays are long for a trail bike at 465mm across the 29er builds, a Bulls trait carried through the Sonic EVO range.

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

Wheels

Descending

A solid all-round descender (67° head angle, 120mm) — capable in the rough and steep without being an all-out bruiser.

Playfulness

A fair bit of pop, but happiest on flowing trail rather than trials moves.

Size balance

Rear-long with a planted front in L (FC:RC 1.61) — easy to weight the front and quick to turn, though it can feel light at the back at real speed.

Technical climbing

Climbs well — a 74° seat keeps the front planted. 600W of peak power and 85Nm of torque — a strong full-power motor.

Best suited toAll-round trail riding across mixed terrain.

No single standout trait — a balanced, versatile bike.

Watch out forNo major red flags in the L geometry.

The numbers are well balanced for its category.
