Bulls SONIC EVO TR 1 29

The "SONIC EVO TR 1 29" model from Bulls, released in 2024, is a high-quality e-mountain bike that stands out for its technical specifications and robust construction. The frame is made from 6061 aluminium and was manufactured using hydroforming. It is designed to accommodate a 1.8 steerer tube and features internal cable routing as well as a telescopic seatpost. The maximum load capacity is 150 kg, which highlights the bike’s stability and load-bearing capacity.

The SONIC EVO TR 1 29’s braking system utilises Shimano hydraulic disc brakes, specifically the BR-MT420 models. The brake discs have a diameter of 203 mm at both the front and rear (SM-RT30 CL at the front and RT-EM300 CL at the rear), ensuring excellent braking performance. Gear changes are handled by the Shimano Cues RD-U6000 system with a Shimano Cues SL-U6000 shifter, and the bike offers a total of 10 gears.

The Bulls Lytro 34 Air 1.8 Boost fork, with 120 mm of travel, and the 120 mm rear shock ensure a comfortable ride even on rough terrain. The bike is fitted with MonkeyLink Connect for the front light (not included) and a MonkeyLink Twinlight rear light. The ZECURE MTB pedals provide a secure grip, and the Bulls crankset measures 170 mm.

The Shimano CS-LG400-10 cassette offers a range of 11–48 teeth, whilst the drivetrain is based on the Shimano LG500 model. The handlebars are Bulls Riserbars, the grips are Comfort Sport, and the stem is the Bulls MTBi-Sport, which is CCS Slot Mount ready. The headset is an ACROS 310.52.570R1.

The bike’s rims are Rodi TRYP30 evo tubeless-ready, and the tyres are Schwalbe Smart Sam K-Guard in size 65-622. The hubs are also by Shimano (HB-MT400 at the front and FH-MT400-B at the rear). The saddle is a Prologo Proxim 400 wide model, and the seatpost is a Limotec Alpha 1 with a diameter of 34.9 mm and a length of 170 mm, operated by an SL-MT500-IL lever.

A particular highlight is the drive system: the bike is powered by a Bosch Performance Line CX motor (Smart System) with an output of 25/85 Nm. The battery is a Bosch PowerTube with a capacity of 625 Wh, and the display is the Bosch LED Remote model. A 4 A charger is provided for recharging. An ABUS battery lock provides additional security.

The price for the SONIC EVO TR 1 29 is 5199 EUR, which seems justified given the extensive specification and high-quality components.
