With two PowerTube batteries stylishly integrated into the down tube, the QUADRIGA DUO E-TR BELT is difficult to beat when it comes to range. A 1250 Wh battery capacity supplies a powerful 4th-generation Bosch Performance Line CX motor; the motor is controlled via the Kiox colour display with extensive connectivity functions. Top comfort is assured with a 100-mm suspension fork and a suspension seatpost that is also adjustable in height at the same time (Eurobike Award winner 2019), in addition to the continuously variable ENVIOLO gear shift with extremely low-maintenance belt drive. The steady four-piston disc brakes are supplied by SHIMANO.
