What's the point in having a bike that helps you go farther and makes you want to stay out all day if the battery isn't up to the task?

Welcome to the endurance steeds of the BULLS eMTB line-up. The all-new, all-mountain E-Stream EVO AM series boast the new Brose Drive S Mag motor—smaller and lighter than the previous generation with even more power and torque. But, what really sets this eMTB apart is the BULLS Supercore battery. One battery. 750Wh. That's an optimal range of over 150 miles. As if that weren't enough, both models are complete with Fox 150mm front and rear suspension.

Dropper posts

A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.

Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.

Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.

Plus-size rims and tires

Wider than standard yet narrower than fat, plus-size rims and tires hit the sweet spot in grip, stability, and speed, giving you more confidence on technical terrain. Compared to a standard tire you’ll feel grip in places you wouldn’t expect thanks to a bigger contact patch and greater rollover clearance. More air volume allows lower tire pressures which softens bumps and increases float on sand or snow. Whether you’re a novice or an expert, the benefits of plus-size tires and rims will amplify your mountain biking fun.
