Bulls Sonic EVO SX2
Sporty, light and manageable. These are the most striking characteristics of the new Bulls Sonic EVO SX2! The German manufacturer opens a new trend of lightweight e-bikes with the revolutionary Bosch Performance Line SX motor drive with a lightweight Bosch CompactTube 400 battery. The drive electronics of this unit weigh only 4 kg. In the context of these weight components, a redesigned RockShox SID RL DEBONAIR fork and SRAM GX AXS electronic shifting are also installed on a lightweight carbon frame
Sonic models rely on their proven modern geometry, low-profile tubes and distinctive head for a perfect aesthetic experience and a fully agile, pleasantly controllable e-bike.
