The Tern Surge is a modern minivelo. It brings together a unique package of small wheel and diamond frame benefits. While it doesn’t fold, it’s got the compact footprint and faster acceleration of a small-wheeled bike. Thanks to its svelte aero frame, it’s competitively lightweight, yet strong and rigid. With deep rims, integrated brifters, and drop bars, it rides and feels like a road bike, just one designed from the ground up for city living.

  • 451 minivelo design for urban maneuverability and portability
  • Short reach drop bar with Claris STI levers for integrated shifting precision
  • Smooth welded aero-edge tubing for a bold and aggressive ride
  • Internal cable routing for clean body lines
  • Matte black semi-deep rims for rigidity and performance
  • 2 × 8 Shimano Claris drivetrain for speed and versatility
  • ‘Capsule Collections’ for unique limited-edition variants
  • 451 wheels
