The Fit Pro measures 130.5 cm deep × 60 cm wide × 13.5 cm high. The 13.5 cm height is the critical clearance figure — if your desk frame or crossbar sits more than 13.5 cm above the floor, the treadmill will slide underneath. The 130.5 cm deck length and 60 cm width determine the floor footprint when deployed.

The Fit Pro supports users up to 110 kg. The alloy steel frame construction is what underpins this capacity — the material provides the structural rigidity needed to handle that load consistently across repeated sessions.

The motor is rated at 2HP peak DC. Peak rating reflects the motor's maximum output under load. This is the correct spec for an under-desk walking treadmill where the motor operates at moderate, sustained speeds rather than high-intensity sprint loads.

The maximum speed is 8 km/h. The Fit Pro is designed for walking and low-impact jogging — it is not a running treadmill. Buyers looking for speeds above 8 km/h or high-intensity interval training should consider a full-size treadmill. For desk-based walking sessions or light cardio, 8 km/h is the appropriate ceiling.

The unit weighs 22 kg. For context, many under-desk treadmills in this category weigh 25–30 kg. At 22 kg, most adults can reposition or store the Fit Pro without assistance, making it practical for shared spaces or rooms where it needs to be moved regularly.

The frame is made from alloy steel. This is a structural material choice that contributes to both the unit's durability and its 110 kg weight capacity. Alloy steel frames resist deformation under repeated load better than plastic or standard steel composites.
