The engagement problem

Recumbent bikes are comfortable, but they don't ask much of your core or balance

A reclined seat and back support make for an easy ride, but that same setup takes the core and stabilizer muscles almost entirely out of the workout, and it feels nothing like riding an actual bike.

The Star Trac SUBx Upright Bike keeps riders in a natural, seated cycling posture that engages the core and mirrors the feel of road cycling, while staying every bit as low-impact on the joints. Dynamic Heart Rate Control automatically adjusts resistance to keep effort in the right zone during interval work, no manual fumbling with levels mid-ride.

A wide, cushioned seat and an easy-up adjustment lever keep it comfortable for extended sessions, without sacrificing that upright, engaged riding position. The result is a ride that still feels like exercise, not just recovery time.

What dealers say

Not built to be just another stationary bike

"One word you'll never hear used to describe our bikes is 'ordinary.' Settle into its wide, cushioned seat and press start on the most user-friendly display on the market."

Fitness Factory, Authorized Star Trac Dealer

For riders who want the reclined comfort of a recumbent, Star Trac's own SRBx and 4RB cover that well. The SUBx exists for facilities and riders who want an upright, more athletic ride instead, with the same commercial-grade frame and console quality carried across the S Series line, at a price well below a full studio-cycling installation. Warranty coverage is tiered by use case: a 10 year structural frame warranty applies across the board, paired with 10 years parts and 3 years labor for consumer use, or 3 years parts and 3 years labor in light commercial settings, so facilities know exactly what's covered before it ever ships.

Best for

Riders who want an upright, road-bike-style posture with real core engagement, and commercial gyms or multi-housing facilities that want a durable upright option alongside recumbent equipment.

Includes free delivery. The Fitness Outlet is an authorized Star Trac dealer, ensuring full manufacturer warranty support on every purchase.
