Hiboy S2 Pro & Hiboy KS4 Pro share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Hiboy S2 Pro rather than the Hiboy KS4 Pro.
Why Do I Recommend The Hiboy S2 Pro?
- The Hiboy S2 Pro has a lighter 37.4 lb frame for easier portability and carrying up stairs, whereas the Hiboy KS4 Pro has a heavier 40.6 lb frame that is harder to transport.
- Hiboy S2 Pro features a narrower 16.5-inch deck for more agile handling in crowded urban areas, while the Hiboy KS4 Pro uses a wider 18.9-inch deck that takes up more space.
- It comes with a compact folded 19.3 inches height for simpler storage under desks or in car trunks, whereas the Hiboy KS4 Pro folds to a taller 20.7 inches that requires more clearance.
- The Hiboy S2 Pro supports a 15% climbing angle for better performance on steep hills and inclines, while the Hiboy KS4 Pro supports around a 12% climbing angle that struggles on steeper slopes.
- Hiboy S2 Pro includes dual rear spring suspension for improved shock absorption on bumpy city roads, whereas the Hiboy KS4 Pro relies on a different shock absorption layout.
- It comes with a classic hinge and safety clip stem latch for quick folding and unfolding, while the Hiboy KS4 Pro uses a bulkier latch that takes slightly longer to secure.
- The Hiboy S2 Pro uses a standard kickstand with a slim design to keep the scooter stable without adding extra weight, whereas the Hiboy KS4 Pro uses a longer and wider kickstand.
- Hiboy S2 Pro has a slimmer rear fender for a lighter profile and less obstruction when moving the scooter by hand, compared to the Hiboy KS4 Pro’s wider reinforced fender.
Maybe the Hiboy KS4 Pro price can make you comfortable because it’s a little bit cheaper than the Hiboy S2 Pro. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
