Who is this bike for?

Tern's latest model, the HSD is designed to sit in the middle of their eBike range between the GSD and the Vektron. Boasting a impressively large max gross vehicle weight compared to its actual weight - 170kg to 25.4kg, the HSD will happily manage the school run on the way home from the supermarket!

While still being easy to manoeuvre and store, due to its lighter credentials and short wheelbase. Thanks to Tern's Andros G2 stem, the HSD will be flexible for the whole family, accommodating riders from 1.5m to 1.95m.

Electrical System

Assisting you while you nip around town on the HSD is Bosch's Active Line Plus motor. Featuring 50Nm torque, utilised across four modes of assistance (eco, tour, sport, turbo), combined with the 400Wh battery, autonomy will be between 25 and 95 miles.

Combining the Gates CDX Carbon belt with the internal Shimano 8-speed hub gear provides a clean, hassle free and low maintenance ride!

Smooth Riding

Not only does the Active Line Plus motor provide the rider with minimal resistance while switched off, or over 15.5mph, it is also exceptionally quiet and smooth in power delivery.

Providing up to 50Nm of torque across four levels of assistance (eco, sport, tour, turbo), combined with a 400Wh Bosch Power Pack, riders will see between between 25 and 90 miles of assisted travel (conditions, assistance mode, and rider will have an impact).

Gates CDX Carbon Belt

With a lifespan of around 20,000 miles, the CDX carbon belt won't stretch or wear in the same way a chain will. Also around 100g lighter than a traditional chain, with no need to lubricate or degrease, a carbon belt is extremely easy to live with.

Bosch Power

A 400Wh Bosch PowerPack provides the power for the HSD to transport you and your cargo to your destination. Riders will see assisted travel between 25 and 90 miles. Conditions, rider and assistance mode will have an impact.

Sleek Display

Situated on the left hand side of the handlebars, the sleek Bosch Purion display packs a lot of data in! From assistance mode to predicted range, the Purion makes ride info easy to view. This display also controls the lighting and Walk Assist.

Impressive Carrying Capacity

The strengthened front mounting point on the HSD S8i allows for the easy transportation of your laptop, dinner, sports kit or many other items. Compatable with a range of Tern accessories.

Stopping Power

Magura MT4 hydraulic disc brakes provide the stopping power, whether you are laden with cargo or on your way to the market, you can place your confidence in your stopping ability.

Tern Andros Stem

Built for riders of 150cm to 195cm, the HSD S8i accommodates for multiple members of the family.
