Who is this bike suitable for?

Those with a multi-transport commute need look no further! Maybe you live a little too far from the station to cycle a push-bike, but certainly not so far that a car is necessary. The Tern Vektron folds down in under 20 seconds, is allowed on all forms of public transport and is far more enjoyable than the tube at the other end of your journey!

The Vektron D8 is ready for your commuting needs straight out of the box. A large cargo rack suitable for panniers ensures you’re free from back sweat, front and rear mudguards will keep your smart clothing dry in all conditions, and integrated lights ensure you’re visible day and night!

What Makes it Different

There are few folding eBikes on the market which successfully integrate the smoothness of a crank motor with the portability and ease of use of a folding bike. The Vektron being an exception to this…

What the expert says

'To help the rider find the perfect fit, the stem is adjustable. The bike also boasts dynamo powered lights alongside hydraulic disc brakes. The bike will suit riders from 4 ft 10 to 6ft to 5, and also integrates with a child seat. The total weight is 22.5kg, making it admittedly a fairly hefty folder - but that's fairly uniform across electric versions.'

Key Features

Utilising Bafang's M400 drive system combined with a 400Wh battery from the same manufacturer, your estimated range is between 25-60 miles. As to be expected, the D8 gives your four assistance levels to chose from. So as you come to the end of the week, you can crank the assistance up and let the M400 system do the work!

Shimano hydraulic disc brakes and Schwalbe Big Apple tyres will provide control and comfort during your ride, be this in the wet or over extra long distances.

Fitted on the handlebars is Tern's flexible and adjustable stem, the Andros system. Whether your Vektron is being used by different riders, or you want to change up your riding position with as little hassle as possible, the Andros allows this - with no tools!

Additionally, Tern's 150 lumen Valo headlight sits on the stem, illuminating the rise ahead!
