BULLS introduces a cleaner integration of the drive unit into a sophisticated frame concept. The SIX50 E 1.5 shines with its all new sporty characteristics. One of the core features of this eMTB is the powerful Bosch Performance Line CX, a strong 250W mid-drive unit. With an impressive continuous torque output of 75Nm every pedal stroke gives you an incredible boost to get you through your ride.

Power is supplied by a 36v, 500 watt-hour battery that sits flush on the top tube. You’ll be able to reach an impressive range of 110 miles in optimal riding conditions making those long trails on a single charge possible.

Constructed around an aluminum frame this eBIKE features everything you could possibly want out of a hardtail mountain bike. Innovations like a tapered head tube to improve handling, internal cable routing, and a tilted motor to allow for more ground clearance are only a few details that will keep you riding harder.
