Head-to-Head Specs
Here are the two models side by side, from the Amazon US listings of the 2026 models and Sole’s warranty page. A check mark shows the stronger spec on each line. Before you order either model, search the CPSC recall database: the U.S. Consumer Product Safety Commission lists treadmill recalls and the fix offered. The American Heart Association recommends at least 150 minutes of moderate or 75 minutes of vigorous aerobic activity a week. If you train for road races, a 1996 study of trained runners found that a 1% incline best matched the energy cost of outdoor running at about 6.5 to 11 mph.

Round 1 of 5
Sole F63 vs F65: Motor, Speed and Incline
Sole F65 wins this round
Both run from 0.5 to 12 mph and climb to 15% under motor control. The F65 lists 3.25 HP, the F63 3 HP with a brushless design that Sole says runs quieter.
For walking, hills and steady jogs, both have power to spare. Testers of the 2026 F63 noticed slight shaking at high speed on a steep incline, so the heavier F65 is the steadier platform for faster running.
Round 2 of 5
Frame, Deck and Comfort
Sole F65 wins this round
Both list a 20 × 60-inch cushioned running surface. The F65 sits on a frame 80 lb heavier and is rated for 350 lb, which reviewers of the F65 and its close siblings link to a sturdy, stable feel.
Reviewers also describe the F65 deck as firm. Testers of the 2026 F63 found its deck comfortable and roomy for runners up to about 6 feet.
Round 3 of 5
Console and Programs
Tie. Neither model has a clear edge here.
Both use LED consoles with Bluetooth and the free SOLE+ app, and neither needs a membership. The F63 adds speed and incline dials in the hand grips, USB-C charging and Bluetooth speakers.
The F65 lists 10 programs; the F63 lists 10 preset, 2 user and 2 heart rate programs with a Bluetooth heart rate receiver.
Round 4 of 5
Footprint, Folding and Moving
Sole F63 wins this round
The F63 needs about 75 × 34 inches of floor and weighs 187 lb; the F65 needs 77 × 36 inches and weighs 267 lb. Both fold and roll on wheels.
Folded, the F63 takes less floor (42 × 34 inches against 48 × 36) but stands 5 inches taller. The 80-lb difference matters most when you fold, roll or carry it upstairs.
Round 5 of 5
Warranty and Support
Tie. Neither model has a clear edge here.
Both list lifetime frame and motor coverage, 2 years on parts and 1 year on labor from Sole.
Coverage does not separate them.

Final Verdict
The Sole F65 is the better pick if you run, weigh more than 325 lb or want the steadiest frame. If you mainly walk on an incline or jog at steady paces in a smaller room, the Sole F63 gives you the same speed, incline, deck and warranty in a treadmill 80 lb lighter.
