https://electricbikereview.com/ The Haibike XDURO Trekking S RX has been upgraded to Trekking 4.0 for 2017 and includes the Bosch Powerpack 500, an air fork with thru-axle, and Shimano Deore XT drivetrain with SLX shifters. The frame style has been improved slightly with tighter motor integration and battery interface that Haibike calls “step-in”. The Trekking S RX shown here is a sporty, 28 mph, commuter-ready, electric bicycle made in six frame sizes across two styles, a stiffer high-step and easy approach step-thru. Reinforced fenders stay quiet, oversized rack with spring latch and Racktime connector, integrated LED lights with aimable 60 LUX headlight. Hydraulic disc brakes provide excellent stopping power, 10-speed Shimano Deore drivetrain with larger 20T chainring for high-speed cadence. Excellent weight distribution, removable display and battery pack with forward-compatible interface, gel saddle and suspension fork provide comfort.
