Vektron D7i

The Accelerator
€2,599

The Vektron is a best-in-class electric bike that folds in 10 seconds to go on trains, in cars, and under desks. With an electric drivetrain, 20” wheel bikes are just as fast as 700c. That means riders can enjoy all the benefits of small wheels—compact size, low center of gravity, quick acceleration, maneuverable handling, and plenty of cargo space—with big wheel speed.

The Vektron D7i comes equipped with a Nexus 7 drivetrain. With all the gearing on the inside, your bike is simple and tidy. Paired with Shimano hydraulic brakes, a heavy-duty Tern Cargo Rack and full fenders, the Vektron D7i is up for all occasions.

Product Reviews

The Tern Vektron is suitable for taking children and transporting groceries. Folded, it is as big as a long-distance suitcase and can be taken on the ICE train.

The Vektron can be quickly and easily shrunk to Hobbit size. The folding hinges and their closing levers are intelligently designed, the frame is rigid and very stable.
