Jamis Bikes | 2023 Sequel S3

📏Size Guide

Built for the city, ready for everything beyond it.

The Jamis Sequel S3 is a steel urban adventure bike designed for riders who want everyday practicality, all-road comfort, and confident handling across city streets, bike paths, and mixed terrain.

Built around Jamis’ 4130 double-butted chromoly frame platform, the 2023 Sequel S3 combines the smooth ride quality of steel with wide 650B tires, hydraulic disc brakes, and a simple Shimano Altus 1x9 drivetrain. Unlike traditional rigid hybrids that can feel harsh and nervous on rough roads, the Sequel S3 focuses on comfort, stability, and versatility for commuting, fitness riding, urban exploration, and light gravel adventures.
