CARRIES YOUR WHOLE WORLD

The HSD hauls up to 419 lb of rider, passenger, and cargo — a kid on the back, a partner, or a week of groceries — while staying shorter than a standard bike.

POWERED BY BOSCH

Every HSD runs Bosch's latest Smart System, with up to 90 Nm of torque on the Sport models to flatten the Bay Area's steepest hills. Smooth, quiet, and proven over years on city streets, it's the best e-bike drive system on the market.

STABLE UNDER ANY LOAD

A longer wheelbase, lower center of gravity, and a stiffer frame keep the HSD planted and predictable — even fully loaded and moving at speed. Magura hydraulic disc brakes bring it all back down with confidence to spare.

FITS EVERY RIDER

The tool-free Comfort Cockpit adjusts in seconds, so the same bike fits a petite rider and someone up to 6'9". One HSD can be shared across the whole household without a single wrench.

SMALL ENOUGH TO LIVE WITH

The HSD folds flat and parks vertically, tucking into an apartment hallway, a closet, or the back of a car. You get real cargo capability without giving up your floor space.

BUILT BY TERN

Tern has spent over a decade on a single idea: bikes that replace cars for real families. Every HSD frame is independently tested and certified to carry 419 lb, so the bike you trust with your kids is built to last for years.
