The Bulls E-Core Di2 FS 29 merges outstanding design, state-of-the-art drive technology, perfect speed changes and true off-road-capacity. Perfectly integrated, the Shimano Steps E8000 motor with its powerful 500Wh frame-integrated battery ensures maximum performance while keeping the weight down to a minimum.

With the Shimano XT Di2 electronic gear shifting system, the Bulls E-Core Di2 FS 29 offers what is probably the best way of shifting gears at the moment.  Rock Shox front and rear suspension, Magura hydraulic disc brakes and Schwalbe Nobby Nic Performance round out this excellent perfomance all-terrain electric mountain bike.

Shimano Steps E8000

The high-power Shimano Steps E8000  motor delivers a smooth 70Nm of torque capable of taking you to the top of almost anything. There are three assistance modes: Eco, Trail and Boost, with the latter providing 300% assistance. The E8000 system also has a walk assist function to help manage the bike when you’re pushing not riding!

 Small is beautiful

The Shimano drive unit’s small form factor enables BULLS designers to incorporate shorter chainstays, this allows E8000 equipped bikes to benefit from the decades of frame geometry development that has gone into manual MTBs. Additionally, the very narrow width of the E8000 allows the retention of manual MTB’s narrow pedal position, resulting in a natural and efficient pedal stroke.  Combining these features ensures a perfectly balanced riding position that other manufacturers can only dream of.

Weight the enemy

At 2.8kg,  the STEPS drive unit is a full kilo lighter than the Bosch drive system. While the Bosch unit uses a small drive sprocket that’s geared up from the crank (more moving parts = more mechanical losses), the Shimano is direct-drive, enabling use of 34T or 38T chainrings. The image shows rearward location of the hollowtech shaft and short chainstays.

▶Tune and Update with Bluetooth

Using the Shimano E-tube app on your PC, tablet or smartphone, you can adjust the preset power modes on your E8000 powered e-bike to create personalized assistance levels on the fly with Bluetooth connection. No cables necessary!

Shimano Deore XT Di2

Shimano Di2:  “Shimano Digital Integration Intelligence” – Di2, get it?  This clever electronic system shifts reliably and precisely come rain or rocks.
