Both the Ninebot by Segway KickScooter F3 Pro and the Segway SuperScooter GT3 share a strong foundation of practical design features: both fold for storage, ride on pneumatic tires with suspension, carry front and rear lights, and hold an IPX6 water-resistance rating — meaning neither is fazed by heavy rain or splashing water. Neither is designed for kids, and both pair with a dedicated smartphone app. At this level, they are evenly matched on safety and convenience essentials.
Where the two diverge significantly is in physical scale. The GT3 is substantially larger, standing 1388 mm tall and 1360 mm wide versus the F3 Pro's 1262 mm height and 1152 mm width. More striking is the weight gap: the GT3 tips the scales at 39,500 g — more than double the F3 Pro's 19,300 g. Even folded, the GT3 is a two-handed, commit-to-carrying proposition, while the F3 Pro remains manageable for most adults navigating stairs, public transit, or tight storage. The GT3 also runs slightly larger 11″ wheels compared to the F3 Pro's 10″, which can contribute to a smoother roll over uneven surfaces but adds to the overall bulk.
On design, the F3 Pro has a clear practical edge for users who prioritize portability and everyday handling. The GT3's greater mass and dimensions are clearly the trade-off of a machine built for more demanding performance use cases — its heft is a design consequence, not an oversight. If compactness and ease of transport matter, the F3 Pro wins this group outright; if you rarely need to carry the scooter and want the larger platform, the GT3's size becomes a non-issue.
