Cycle 2 Work Schemes
Power up your commute
We work with a number of cycle scheme providers to help make the purchase of your new eBike and accessories more affordable. Cycle schemes allow you to make a tax-free purchase, saving up to 47%, by paying for the eBike and accessories out of your pre-tax salary. Better still, being a salary sacrifice scheme, the payments are taken out of your salary over an extended period (usually 12 months) meaning you get to spread the costs also!
Cycle to Work schemes can be processed by emailing us at firstname.lastname@example.org.
Who is this bike suitable for?
Tern's HSD boasts an impressively large maximum gross vehicle weight rating of 170kg, meaning the HSD will happily manage the school run, weekend outings or carrying a whole lot of cargo.
With a longer wheelbase and extra-low center of gravity, the HSD is smoother and more stable than your standard ebike. Also it is easy to store, thanks to a folding stem and the capability to stand on it's rear end.
A cleverly adjustable stem and seatpost means you can find a comofortable and upright position, while being flexible for the whole family, accommodating riders from 1.5m to 1.95m.
Whether you need to carry kids, cargo or if you want a versatile commuter, the HSD is a bike of many talents, and capabilities.
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!
What the expert says
‘The HSD can handle up to 374 pounds, accepts one child seat, and works with a variety of cargo accessories for the front and rear for all your commuting and errand-running pleasure.’

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.
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.
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.
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.
