Hiboy KS4 Pro Electric Scooter vs Hiboy S2 Pro Electric Scooter

These are near twins: same 500W motor, same 36V 11.6Ah battery, same 19 mph top speed, same 10-inch solid tires and rear suspension. The S2 Pro adds the Hiboy app for locking and tuning acceleration and braking, and it has far more owner ratings behind its 4.8 score. The KS4 Pro adds a three-light system with sidelights and a reinforced fender. Pick the S2 Pro for app control and a longer track record; pick the KS4 Pro if you ride at night and want extra visibility.

• Choose the Hiboy KS4 Pro if you ride after dark and want headlight, taillight and sidelights, or you want the reinforced fender and slightly higher peak motor rating.
• Choose the Hiboy S2 Pro if you want app-based locking and adjustable acceleration and braking, backed by a much larger pool of owner ratings.
