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.
