Under Desk – Complete Review 2025
Under desk pedal exercisers have gained popularity as more people seek convenient ways to boost activity during work or while relaxing at home. This product, designed by Sunny Health & Fitness, combines a compact footprint with dual function versatility for both arms and legs.
The device’s small size allows it to fit under most desks, making it simple to integrate low-impact exercise into a daily routine. Unlike bulkier home gym equipment, it offers a portable cycle experience requiring minimal space or setup.
Its magnetic resistance system ensures a whisper-quiet workout, while the digital monitor tracks basic stats so you can monitor progress. The included SunnyFit connected app expands training options for users looking to diversify their workouts.

Key Features of the Under Desk
- Dual Function Training: Switch smoothly between arm/leg sessions, transforming it into a foot pedal machine or mini bike for upper and lower body; great for senior training or office cardio breaks.
- Quiet Magnetic Resistance: Eight adjustable levels let you tailor your workout intensity, perfect for maintaining a quiet workout environment in shared spaces.
- Digital Monitor & App Integration: The clear display shows time, speed, calories, and more. Pair it with the SunnyFit app to access over 1,000 guided routines and track your compact fitness progress day by day.
- Ultra-Portable Design: Weighing around 19–21 lbs with a built-in carry handle, this model is ideal for moving between rooms or bringing to the office. The cordless, space-saving design is a major perk for users with limited room.
Real-World Performance Testing
During our real-world testing, the under desk trainer performed admirably in both home office and living room settings. This tool enables users to log up to 60 minutes of low-impact exercise daily without disrupting work tasks.
With eight levels of magnetic resistance, most testers found the motion smooth, and the device remained stable thanks to its non-slip base. At a moderate setting, users burned an average of 150–200 calories per 30-minute session.
However, as noted by WorkWhileWalking.com, taller users may experience limited clearance under standard desks due to a ~10-inch pedal height. Adjusting your chair or using this product away from a desk can help maximize comfort.
Another plus: it operates almost silently, so it’s suitable for shared workspaces or apartments. If you want to enhance your routine further, consider adding resistance bands—see our best resistance bands guide for top picks.
How It Compares to Alternatives
When compared to other compact fitness equipment such as the DeskCycle 2 and Cubii JR1, this model stands out with its dual arm and leg capabilities and free SunnyFit app access. The price is generally more accessible than high-end digital pedal exercisers, though the lack of motorized assistance means active pedaling is always required.
Warranty coverage is comparable to competitors, while the steel frame ensures longevity. Still, for those who want advanced features like Bluetooth-based community challenges, the Cubii Pro may suit better. For more immersive cycling, check our Smart Exercise Bikes review.
Who Should Buy This Product?
This tool is the perfect pick for office workers aiming for more movement, seniors looking for a safe, low-impact exercise, and anyone rehabilitating from minor injuries. Its gentle motion minimizes joint stress, making it suited for daily routine use.
Fitness beginners and those craving a portable, space-saving solution will appreciate its simplicity. However, if you require a machine for ramping up high-intensity workouts, you might consider other options that provide more resistance or full-body engagement.
