The flagship offering of the firm's fabulous range of folding bicycles, the Tern Vektron S10 rides like a regular, high-end e-bike. If you need to mix your modes of transport up, it's easily manageable on a bus or train, and slots neatly in the trunk of a car. Features include a premium Bosch Active electric drivetrain, child seat-compatible rear cargo rack and a Valo lighting system. What's more it re-sizes in seconds for riders ranging from 147-195cm, meaning it can be shared.
