HSD

Meet the HSD

Enormously Useful. Surprisingly Smaller.

The HSD is mighty but mini: It's easy to handle, easy to share, extremely comfortable to ride, carries a whole lot of cargo—and all of this in a compact design that's shorter than a standard bicycle.

Easy to Handle

Whether you're riding, storing, or moving it around, the HSD is a breeze to handle. It's shorter than a regular bike and its weight is the same as a regular ebike.

Kiddie Carry

Bring the kiddo. The HSD's extra-long Atlas H Rack gives plenty of heel clearance and room for your kiddo to enjoy the view rather than being smushed up against your back. The rack is rated to 60 kg (132 lb), so when paired with the upcoming Passenger Kit, the HSD is ready for your growing family.

Need to carry a kid? Here's Here's how you can safely carry passengers on the HSD.

Passenger System

Flat Fold

Fifteen seconds and the HSD transforms into a flat package that's perfect for fitting into SUVs, station wagons, or bus storage compartments.

Ready to Haul

Despite its diminutive stature, the HSD is a mid-sized cargo bike with some serious hauling capacity. With a maximum gross vehicle weight of 170 kg (374 lb) and an XL-sized Atlas H Rack, it'll carry a week's worth of groceries or camping equipment for the weekend. It even has a dedicated trailer mount, so adding extra cargo is a cinch.

Vertical Parking

The HSD flips up for convenient vertical parking. Take it upstairs in an elevator and park it inside at home or at work—it needs just a wee bit of floor space.


The HSD can handle up to 374 pounds, accepts one child seat, and works with a variety of cargo accessories for the front and rear for all your commuting and errand-running pleasure.

A Comfier Ride

With a longer wheelbase and extra-low center of gravity, the HSD is smoother and more stable than your standard ebike. Easy-Step frame design paired with an adjustable stem and seatpost offers a comfortable upright riding position for both taller and shorter riders. Add a suspension fork and balloon tires and even the meanest cobblestone roads are comfortably navigated.

Happiness Shared Daily

The best things in life are meant to be shared, and the HSD is one of them. The HSD resizes in seconds to fit riders from 150 to 195 cm (4'11" to 6'5") so everybody in the family—from teens to grandparents—can enjoy the ride. The Easy-Step frame design is nice and low for easy mounts and dismounts.

Automatic Shifting

The new Enviolo AUTOMATiQ system does all of the shifting for you, so you can worry less and bike more. All you need to do is pedal. It'll shift up as you accelerate from a standstill, and shift down when you reach a stoplight. Set your desired pedaling cadence on the integrated Bosch Intuvia controller and let Enviolo do the rest.

Cargo Bike Tough

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.
