With world class leading innovations and one of the most powerful electric bike systems in the world BULLS has easily set itself apart from its competitors. Built around an aluminum frame with performance in mind, you can find all the latest eBike technology developed into this model.
Outfitted with a Bosch Performance Line CX, 350W, mid-drive motor you’ll be able to charge up any steep terrain. With a max torque output of 75Nm the bike’s potential will let you discover trails you’ve never seen before. In addition, the motor has been redesigned to integrate with the complete bike seamlessly. By tilting the motor 60 degrees upwards not only do we improve the aesthetics but also eliminate the need for a chain guide and clear room to allow for shorter chainstays.
The power will be supplied by the biggest battery Bosch has to offer which sits flush on the downtube. The 36V, 500 watt-hour, power pack offers an impressive range of 130 miles in optimal riding conditions. Weaving through those long trails is now made possible on a single charge.
Designed to tear up those trails you’ve always wanted to tackle, the massive 27.5 + tires allow you to have traction at all times. Matched with a reliable set of Shimano Deore XT components you can depend on smooth and low maintenance parts. With RockShox suspension on both the front and rear the SIX50+ E FS 3 is capable of giving you a true off-road adventure. Despite the low price, BULLS does not cut any corners and has spec’d this bike to your expectations.

This is semi-integrated headset with an inner diameter of 1 1/8" at the top and 1.5" at the bottom. This ensures best riding stability and excellent control head stiffness. The biggest shaft results in stiffer fork and frame as riding forces are spread more evenly thanks to a thicker head tube. |

BULLS eBikes are protected by Skid Plate, a shield developed exclusively for Bosch-equipped off-road eBikes which guarantees an action-packed ride on even the most extreme slopes. Like the underbody protection for off-road vehicles, the Skid Plate protects BULLS eBikes from direct impact damage |

Shimano Shadow Plus clutch mechanism prevents the lower arm of the derailleur from pivoting forward as the chain is kept under considerably more tension. The benefits are many: less chain slap, fewer dropped chains, more stable and accurate shifting over rough terrain and ultimately a much better and quieter ride. |

The main advantages of the thru-axle system are stiffness and strength, which add together to a safer bike. It has a clear advantage on disc brakes over the traditional quick release as it allows for easier and more precise wheel mount/dismount operation. |

Internally routed shifting and braking cables ensure a clean and elegant look while ensuring a better protection to all important cables. |
