Star Trac 4 Series Upright Bike in a fitness facility

The auto-pilot problem

Some riders don't want the bike to set the pace for them

Auto-adjusting resistance is convenient, but plenty of riders would rather dial in their own intensity, especially during interval work where hitting an exact level matters more than staying in an average zone. Handing that decision to an algorithm can feel like giving up control right when it matters most.

The Star Trac 4UB Upright Bike keeps that control in the rider's hands with 40 levels of resistance and Quick Key one-touch presets, so switching from a warmup pace to a hard interval takes one press, not a menu. Racing-style handlebars and elbow supports add a more realistic cycling position than a typical upright console setup.

An easy-up seat adjustment and Soft Trac shock-absorbing pedals round out a ride built for facilities running users through the same bike all day long, where quick turnover between riders matters as much as comfort.

Console options for every budget

Scale the tech to fit the space

Every 4UB shares the same frame, resistance system, and pedals. The console is where facilities choose how much interactivity they want to offer:

10" LCD Display 10" Touchscreen 16" Apex Touchscreen USB Charging Contact Heart Rate Personal Fan

The 16 inch Apex option adds streaming apps and personal device mirroring, while the LCD keeps things simple for spaces that just need reliable, everyday cardio.

What independent reviewers say

A brand built on club-quality reliability

"These award-winning models offer nothing less than real club quality. They are sturdy, quiet, and comfortable, and are backed by excellent customer service."

AllExerciseBikes.net, Independent Exercise Bike Review

Star Trac's own SUBx Upright Bike offers automatic Dynamic Heart Rate Control for riders who prefer to let the bike manage intensity, at a higher price point. The 4UB trades that automation for full manual control and a lower cost of entry, without giving up the commercial-grade frame and 40 levels of resistance riders expect from Star Trac. It's the more affordable path into the S Series build quality, aimed at riders who simply want to run the show themselves.

Ideal for

Hospitality gyms, multi-housing fitness centers, and boutique studios that want hands-on resistance control at a lower price than Star Trac's automated S Series bike.

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