Sonic EVO EN 2022

The 2022 BULLS Sonic EVO EN is the full-power Bosch enduro in the Sonic EVO range, and it should not be confused with the lighter, carbon-framed Shimano-powered Sonic EVO EN-SL sold alongside it. Now discontinued, the EN ran on an aluminium frame with 180mm of fork travel, a Bosch Performance Line CX (Gen 4, 85Nm) drive unit, and the older non-Smart 625Wh PowerTube battery with a Bosch Purion display.

It was a genuine mixed-wheel (mullet) bike: a 29in front wheel with a 27.5in rear, shod with burly Schwalbe rubber (Magic Mary up front, Big Betty or Hans Dampf at the rear depending on trim). Geometry was aggressive for the era at a 64-degree head angle and a 77-degree seat angle, with only two frame sizes offered (44cm and 48cm, reach 450mm and 480mm).

Two builds were sold. The EN 1 (6,497 euro RRP) paired an SR SUNTOUR Durolux 38 fork and Tri Air shock with Shimano Deore four-piston brakes, and Bulls quoted its chassis as 180mm of travel. The EN 2 (7,637 euro RRP) stepped up to a RockShox ZEB Select RC fork and Deluxe RT Select+ shock, TRP DHR GOLD brakes and DT Swiss H 1900 wheels, with Bulls listing 180/170mm of travel. Both used a Shimano XT rear mech with an 11-speed 10-51T cassette and an E-Thirteen crank. BULLS bikes were never given a true GBP RRP, so pricing is quoted in euros only.

This is a positioning and spec summary drawn from BULLS' own 2022 product pages and a period Velomotion test; there is no owner-reported long-term reliability data captured here.
