Bulls presented the new 2025 gravel bikes for the first time at Eurobike, and now the first models should slowly be arriving in the shops. We provide an overview of all the exciting models with and without E.

Classically driven: From the aluminium grinder to the Machete Ti

Bulls continues to rely on a very wide range of conventional gravel bikes, which will even be expanded slightly for 2025. It starts with the Grinder models with aluminium frames, which are trimmed for versatility and everyday use. The sporty highlight remains the Machete models with a stiff and light carbon frame (tested here).

Machete Ti: Special model made of titanium

A special eye-catcher in the gravel range: the Machete Ti with titanium frame, limited to 100 units. A lighthouse project with which Bulls is dedicating itself to the traditional material for the first time in the gravel segment and also setting special accents. Deliberately used cast parts and invisible seams are also intended to give the titanium bike a seamless carbon look. The 5999 euro piece of jewellery with its high-end equipment will be available from May.

With motor boost: Bulls Grinder Evo and Evo SX

When it comes to e-gravel, Bulls is emphasising versatility with the Grinder Evo. All versions of the Grinder Evo come with the new Monkey Link interface for smartphone charging or a matching front light. With numerous mounting points for luggage on the frame and fork, the Grinder Evo is also ideal for bikepacking. The Grinder Evo model with Bafang motor in the rear hub (from €3999, 520 Wh, from 17 kg), which has been known for some time, will be joined by the new Grinder Evo SX from Bulls in 2025.

Like its rear-motor brother, the new Grinder Evo SX has an aluminium frame and a carbon fork, but is propelled by Bosch's sporty Performance SX mid-motor. This offers a strikingly high peak output of up to 600 watts in sprints and particularly low pedalling resistance. The modulation and ride feel are always at the forefront in our motor tests. Qualities that the small Bosch should be able to fully utilise, especially on the E-Gravel.

Bulls Grinder Evo SX: Three models from 3999 euros

The Grinder Evo SX will be available in three model variants from the beginning of 2025. The basic Grinder model comes with Shimano GRX gears and powerful brakes with 180-millimetre discs for €3999. The 400 watt-hour battery can be folded forwards out of the down tube for ease of use.

For commuters and everyday cyclists, the Bulls is also available as the Daily Grinder Evo SX (4399 euros >> available here). A front headlight, mudguards, pannier rack and a kickstand are also on board. A suspension fork with 40 millimetre travel is designed to provide additional comfort. The top-of-the-range Trail Grinder Evo SX model, with its mountain bike cassette, telescopic seat post and Rockshox suspension fork, is much more geared towards off-road use. The price for the bike, which is equipped to a high standard throughout, is 4999 euros.
