Product Details

Tern Vektron Q9 2020 -  Foldable E-Bike

The Tern Vektron Q9 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.

Key Features

The Vektron Q9 is equipped with hydraulic disc brakes, a sturdy rear rack, Valo Direct light, and fenders—so it is ideal for all-season commuting in the city.

  • German-engineered Bosch Active Line electric drivetrain— one of the industry leaders in electric bike technology
  • Shimano 1x9 drive train offers a wide range of gears to get the most out of the drive unit at all times
  • Hydraulic disc brakes for all-weather stopping power
  • New frame design, with a reclining battery for a lower center of gravity and better ride
  • Integrated Atlas Rack works seamlessly with Thule Yepp Maxi and Nexxt Maxi child seats—no adapters needed
  • Resizes in seconds to fit riders 147 – 195 cm (4’10” – 6’5”) so a single bike can be shared by the family
  • Bosch Powerpack 400Wh battery with a range of 50-130km (dependant on weight and terrain)
  • Manufacturer's Weight: 21.9kg, Max Load Weight: 105kg (230lb)
