Product Highlights
Elevated Seat Height
The S660 Forge sits higher than standard horizontal rowers, making it easier to get on and off the machine — a practical feature for taller users, older adults, and those using the rower in a rehabilitation or clinical setting.
Double-Sealed Twin Fluid Tank
The precision-aligned twin tank uses an updated impeller design that achieves 15% greater resistance than previous FDF horizontal models, with tighter tolerances and a more robust feel throughout the stroke.
5-Level Fluid Resistance
Five resistance levels allow users to adjust workout intensity directly on the tank, accommodating a wide range of fitness levels within the same machine without any console programming.
Bluetooth Auto-Adjust Monitor (BAM)
The Interactive Performance Monitor (IPM) automatically detects the selected tank resistance level and adjusts its parameters accordingly, displaying time, speed, distance, stroke rate, calories per hour, and watts in real time.
Heart Rate Compatible
The monitor is fitted with a heart rate receiver as standard and is compatible with all major HR chest belts, allowing heart rate data to be displayed alongside other performance metrics during each session.
Self-Cleaning Seat Rail System
Seat rail brushes wipe away grit and debris with each glide, reducing wear on the rail and carriage and keeping maintenance requirements low in high-use environments.
Premium Steel and Aluminum Frame
The frame is constructed from steel and aluminum with a premium black finish, providing the structural rigidity and durability required for commercial daily use.
Contoured Seat and Ergonomic Handle
The contoured, textured seat provides a stable, non-slip rowing position, while the premium ergonomic handle is designed for a secure grip with minimal wrist and forearm strain across extended sessions.
Adjustable Footboard
Height-adjustable foot plates with secure heel captures allow users to set their foot position for a comfortable and efficient rowing stroke, accommodating a range of foot sizes and rowing styles.
Durable Belt Drive with Active Recoil
A durable belt drive system with an active recoil mechanism provides a smooth, consistent pull and return throughout each stroke, reducing mechanical wear over time.
Vertical Storage and Transport Wheels
The S660 Forge stores vertically to minimise floor space when not in use, and transport wheels are included for easy repositioning within a studio or gym floor.

Frequently Asked Questions
How does the S660 Forge differ from the S680 Timber?
The S660 Forge and S680 Timber share the same fluid tank system and Bluetooth Auto-Adjust Monitor. The key differences are the frame material and seat height. The S660 Forge uses a steel and aluminum frame with an elevated seat height for easier on/off access, and carries a full commercial warranty. The S680 Timber features an American Ash wood-grain frame, a lower seat height, and a residential/light commercial warranty.
What type of resistance does the S660 Forge use?
The S660 Forge uses fluid resistance via a double-sealed, precision-aligned twin tank. The updated impeller design delivers 15% greater resistance than previous FDF horizontal models. Five resistance levels are selectable directly on the tank.
How does the Bluetooth Auto-Adjust Monitor work?
The Bluetooth Auto-Adjust Monitor (BAM) automatically detects the resistance level selected on the fluid tank and adjusts the console display parameters accordingly. This means the monitor always reflects the correct resistance setting without any manual console input. You can also connect a compatible smart device via Bluetooth to sync and review training data.
Can the S660 Forge be stored vertically?
Yes. The S660 Forge supports vertical storage with a footprint of 680 mm x 520 mm (27" x 20") when upright. Transport wheels are included to make repositioning straightforward.
What heart rate monitors are compatible?
The Interactive Performance Monitor is fitted with a heart rate receiver as standard and is compatible with all major HR chest belt brands. A chest belt is recommended for accurate heart rate display on the console.
What does the commercial warranty cover?
The frame is covered for 5 years. The fluid tank and all mechanical and non-wearing components are covered for 2 years. Wearing components are covered for 1 year. The warranty applies to commercial use. Refer to the manufacturer’s documentation for full terms and conditions.
