Tern HSD S+ Folding Electric Bike

A small e-cargo/folding bike that sits atop the HSD range the Tern HSD S+ Folding Electric Bike is ready to haul, take you places and generally be your daily runabout. 

Pre-order: Check availability

Resplendent in silver or 'shake polish' the HSD S+ is packed full of the best riding features to make urban riding and living easier. A Bosch Performance Line motor and 500Wh battery offer up to 74 miles of riding before a charge is needed, more than enough for at least a couple of days riding we'd say!

The bike's gears are from Enviolo, with shifting happening in an enclosed hub and automatically when you ride - one less thing to worry about if it's raining, you want to get home and are faced with an upcoming brute of a hill. There's no standard bike chain either - a Gates Carbon CDX belt drive requires less maintenance and cleaning plus you won't have to worry about an oily stain on your best chinos either. 

Other features of note include a suspension fork and suspension seatpost for extra comfort on rough city roads - don't miss the Magura hydraulic disc brakes either, powerful stoppers if a red light or pelican crossing approaches.
