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.

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.


A balanced mix of smooth riding and agility—without feeling twitchy. An upright position to see over traffic and a sensitive suspension fork for comfort make it suitable for touring as well.

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.

Why the HSD?

IT'S EXTRA-COMFY 

Easy-Step Frame Design

The new Easy-Step frame design offers a comfortable upright riding position for riders tall or small, as well as easy mounts and dismounts.

Adjustable Cockpit

Adjustable Andros stem, Sweep handlebars and precisely engineered Ergon grips combine for a phenomenally comfortable ride.

Suspension Fork

A custom Suntour suspension fork to soak up all those bumps on your daily ride—and to handle the 170kg load that the HSD is rated to.

IT'S A BETTER HAULER 

Atlas H Rack

Extra long and extra strong, the Atlas H Rack handles up to 60 kg (132 lbs) of cargo so you can carry your kid, your groceries, or load it up for a week of bike camping.

Atlas H Dropouts

Custom-forged and loaded with features, including massively over-sized sliding dropouts, a belt access slot, a proprietary new rack mount design, and even a dedicated trailer mount. 

Atlas Wheels + Schwalbe Tires

Wide rims and thru-axle hubs are ready to handle all that weight. Add wide Schwalbe tires with puncture protection and you're ready to roll.

Combo Mount

Burly frame mount with multiple front cargo options. Add a messenger bag for your daily commute or a front rack for a few XL pizzas.

IT'S SAFETY-READY

See and Be Seen

On-board lighting is connected to the main battery so you never need to worry about charging your lights, and reflective tires and decals give you additional night-time safety. And with an upright riding position, you can see and be seen over the tops of cars.

Hydraulic Disc Brakes

The HSD features hydraulic disc brakes for all-weather stopping power—which you'll definitely want when carrying precious cargo on rainy days.

Puncture Resistant Tires

Schwalbe's RaceGuard puncture protection is a tough shield that'll keep you rolling through urban road debris.

Abus Frame Lock

Added security for when you just need to make that quick stop to get your coffee. Best of all, it's keyed-alike to the battery for extra convenience.

IT'S A WHOLE LOT MORE 

Bosch Drivetrain

With outstanding performance and the most extensive service network, the latest generation of Bosch motors deliver not just a smooth ride, but also that extra peace of mind.

Enviolo Automatic Shifting

With the innovative Enviolo AUTOMATiQ, you really just have to pedal. An optional iOS/Android app lets you customize shifting behavior. Equipped on HSD S+.

Gates Belt Drive

Smooth, silent, clean, durable, and maintenance-free—so you can spend more time riding, and less time cleaning your bike chain. Equipped on HSD S+/S8i. 

Cane Creek Thudbuster ST

Exceptional comfort. With a suspension seatpost, you've got extra cush for your tush. Equipped on HSD S+.
