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 pedalling cadence on the integrated Bosch Intuvia controller and let Enviolo do the rest.

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.

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.
