  • The Tern HSD S8i e-bike is a new e-bike in the highly acclaimed Tern range.

The HSD model features strong 20" wheels, a carbon belt drive and 8-speed internal gearing for ease of use and low maintenance. It is powered by the smooth and silent Bosch Active Line Plus mid-drive ebike system and has approximately 100km range with the 400Wh battery.

The Tern HSD is designed to fit as many riders as possible and can be resized in seconds to fit riders from 150cm - 195cm tall thanks to its innovative Andros stem and telescopic seatpost.

It's low stepover height makes it easy to mount and dismount. Its low centre of gravity with the mid mount motor and battery positioning keep the centre of gravity low for a stable, easy to manage and fun ride.  The shorter body makes it agile and manoeuvrable, yet the folding technology allows you to fold it quickly and store conveniently.

Built for fun. Built to last.
