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.
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.
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 right Passenger System accessories, the HSD is ready for your growing family.
Keeping your kid dry and cozy is the key to happier rides and fewer complaints. The Clubhouse Fort Mini transforms the HSD into an all-weather solution to carry your little one all year round.
For many of us, dogs are family too. Build the Doghouse Mini and bring your favorite companion along for the ride.
Fifteen seconds and the HSD transforms into a flat package that’s perfect for fitting into SUVs, station wagons, or bus storage compartments.
