The new lightweight and compact Bosch SX motor packs the support you need to power your wanderlust. By rewarding dynamic and active riding, the system enhances your own efforts with natural and engaging responses. At only 4 kg for the motor and battery, the Grizl:ON is still down to party on the trail. 55 NM peak torque helps you punch up steep pitches, while the 400 Wh battery together with an optional 250 Wh PowerMore range extender (available separately) make big days out off-grid a reality.
