Bulls E-Core Di2 FS 27.5+
Maybe you didn't need a chairlift in the first place. The crazy rollers, drop after climb, after drop after climb, are more your vibe and you're not averse to some vertical punishment. The E-CORE Di2 FS 27.5+ electric all mountain bike takes you there, minus a lot of that punishment you pretend to like.
Integration is this bike's middle name (but we only use it when it's in trouble). The 500Wh power pack is integrated seamlessly into the the downtube. The Shimano Di2 XT electronic shifters are integrated with the battery, eliminating the need for a separate battery and the risk of running out of juice for shifting when you need it most.
Your plush ride is thanks to 150mm of Rock Shox Yari in the front and Deluxe RL Air in the rear. The assist controls are integrated into the shift mechanism that would control a front derailleur on a 2x, so operation is intuitive. Magura MT-5/MT-4 brakes stop your momentum, but not the fun.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
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.
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.
