The Full Scoop on the Tern Vektron P9


  • Tern bikes are available for purchase at our local shops in San Diego and Los Angeles

    The Tern Vektron P9 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 Tern Vektron P9's Schwalbe Super-wide Big Apple tires are like 2" of super-efficient suspension. They roll smoothly over drainage grates, train tracks and potholes with little complaint. The Tern Vektron P9 has a low-step frame design and resizes in seconds—no tools required—to fit riders between 145 and 195 cm (4’10” – 6’5”), so you can share the bike with anyone in your family.
