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?
The Tern HSD S+ is an enormously useful and surprisingly small compact eCargo bike for everyday modern use. It is easy to handle, easy to share, exceptionally comfortable to ride and can carry up to 170kg of maximum gross vehicle weight… all of this in a compact design that’s shorter than a standard bicycle.
Thanks to a new partnership with Enviolo, the S+ offers automatic shifting for you, so you can worry less and ride more. The system shifts up as you accelerate from a standstill, and shifts back down when you reach a stop light. This comes complete with the Gates Carbon Belt Drive.
The S+ forms a convenient combination of compact dimensions and high load capacity, which rides harmoniously and comfortably. Simply put it is an ingenious all-rounder for the weekly shop, the school run or discovering new areas beyond the city.
About the HSD S+
The S+ is Tern’s flagship HSD model, equipped with the Bosch Performance Line motor with an Intuvia display and a 500Wh battery (keyed-alike with ABUS front frame lock) for ranges of up to 75 miles without a single charge.
The integrated Enviolo AUTOMATiQ shifting system, with the Enviolo Sport 380 continuous hub makes sure you can focus simply on riding.
Customer Suntour suspension forks and a Cane Creek Thudbuster ST suspension seatpost ensure comfort over any terrain, and with an adjustable stem handlebar, the S+ can fit riders from 4’11 - 6’5 (150-195cm).
The extra long and extra strong Atlas H Rack can handle up to 60 kg of cargo and can fit your kid, your groceries or can be loaded up for an adventure of your choice.
What the expert says
‘Riding the bike is simplicity itself. It’s comfortable and steady, with a nice upright riding position. Tern has tweaked the cockpit angles, raking the seat angle back a bit so that it works a bit better at the top and bottom ends of the size range.’
‘A cheaper eBike will get you to your destination. But a bike like the Tern HSD will get you there reliably, day after day, and the ride will be so much better thanks to the higher quality components and better engineering of the entire system.’
The Bosch Performance Line motor (Gen 3) provides the right support at the right moment, with a natural riding sensation and a barely noticeable pedal resistance when going over 15.5mph. All of this and almost silent too, for maximum riding enjoyment.
Despite its diminutive stature, the HSD is a mid-sized cargo bike with some serious hauling capacity. With a maximum gross vehicle weight of 170 kg (374 lb) and an XL-sized Atlas H Rack, it'll carry a week's worth of groceries or camping equipment for the weekend
Enviolo Automatiq Hub
the new Enviolo AUTOMATiQ system does all of the shifting for you, so you can worry less and bike more. It shifts up as you accelerate from a standstill, and shift down when you reach a stoplight. Set your desired pedaling cadence on the integrated Bosch Intuvia controller and let Enviolo do the rest.
Despite its stature, the HSD is a mid-sized compact cargo bike with serious hauling capacity. With a maximum gross vehicle weight of 170 kg (374lb) and an XL-sixed Atlas H Rack, it’ll carry 60kg of cargo for your child week’s worth of groceries or camping equipment for the weekend. It even has a dedicated trailer mount.
Folding and Parking
Inside of fifteen seconds and the HSD S+ can transform into a flat package that is ideal for fitting into any SUV, station wagon or bus storage compartment. Similar to all HSD’s and GSD’s the S+ flips up for convenient vertical parking.
