Jamis DXT A3 - Step Thru Hybrid Bike - Seafoam
The Jamis DXT A3 Step-Thru in Seafoam is built to give you the freedom to ride anywhere with confidence and comfort. Designed as a more versatile take on the classic fitness bike, it blends smooth on-road performance with light off-road capability—perfect for commuting, weekend rides, or exploring new paths.
Its lightweight 6061 aluminium step-through frame makes getting on and off easy, while the SR Suntour NVX-DS suspension fork absorbs bumps to keep your ride smooth and controlled. Wide tyres with trail-ready tread grip both pavement and packed paths, so you’re never limited to just the bike lane.
The 21-speed Shimano drivetrain gives you all the gearing you need to tackle steeper hills or cruise effortlessly on flats. Paired with Tektro MD-280 cable-actuated disc brakes, the DXT A3 Step-Thru delivers confident braking power in any weather. Thoughtful touches like the Jamis Touring Saddle and ergonomic geometry keep every ride comfortable, no matter how far you go.
Finished in a fresh Seafoam colour, this bike combines everyday practicality with go-anywhere versatility.
