Easy to Handle
Only 170 cm long, the HSD is shorter than a regular bike. It's a breeze to handle in tight spaces and goes easily where other bikes won't. The HSD flips up for convenient vertical parking and elevator rides, and can be flat-folded in seconds to go into bus racks and SUVs.

Comfier For Everyone
The HSD resizes in seconds to fit riders from 150 to 195 cm (4'11" - 6'5") so everybody in the family—from teens to grandparents—can enjoy the ride. The new Easy-Step frame design offers a comfortable upright riding position for riders tall or small, as well as easy mounts and dismounts.

Safety-Ready
The HSD gets its genes for strength and durability from the GSD. EFBE Prüftechnik GmbH, one of Europe's leading bicycle test laboratories, has tested the HSD frame and fork to 170 kg (374 lb) according to their own rigorous Tri-Test standard and the upcoming EN Cargo Bike standards

Powered by Bosch
The HSD is powered by Bosch's next generation Performance Line or Active Line Plus motors. The motors are smooth, silent, and deliver power with a wonderfully natural feeling. And of course every motor and battery system is backed by Bosch's best-in-class warranty and service.

A Whole Lot More
On top of all the standard features mentioned above, different HSD models are also packed with extras like Gates belt drives, Abus keyed-alike frame locks, and Cane Creek Thudbuster suspension seatposts.
