Hiboy S2 Pro Vs. KS4 Pro: How Do They Compare?

Electric scooters have exploded in popularity in recent years as an eco-friendly and convenient way to commute short distances or zip around town. Two of the top models on the market are the Hiboy S2 Pro and KS4 Pro from leading micromobility brand Hiboy. But how do these premium electric scooters stack up against each other?

In this detailed comparison guide, we’ll break down the key specs, features, pros and cons of the Hiboy S2 Pro and KS4 Pro to help you decide which is the better choice. We’ll also answer some frequently asked questions about these two popular e-scooters

Overview And Specs

Hiboy differentiates its S and KS series of electric scooters as transportation and performance models respectively. As their Pro variants, both the Hiboy S2 Pro and KS4 Pro sit at the top end of Hiboy’s lineup with high-performance motors, extended battery range and speeds, and additional features that enhance the overall riding experience.

At a high level, the KS4 Pro edges out the S2 Pro in terms of raw performance – mainly top speed, motor power, and gradeability. But the S2 Pro is still very capable, while adding advantages in portability. Let’s look at their key specs and measurements head-to-head:

Spec	Hiboy S2 Pro	Hiboy KS4 Pro
Max Rider Weight	260 lbs	330 lbs
Range	Up to 28 miles	Up to 30 miles
Top Speed	19 mph	25 mph
Motor Power	500W	1000W
Hill Grade	15%	25%
Tires	10″ honeycomb pneumatic	10″ honeycomb pneumatic
Brakes	Electric + disc	Electric + disc
Suspension	Front only	Front + rear
Dimensions (unfolded)	45 x 18 x 47 in	47.5 x 21.5 x 48 in
Weight	32 lbs	46 lbs
Water resistance	IPX4 splash-proof	IPX4 splash-proof

Both scooters boast excellent range from their large-capacity batteries, with the KS4 Pro eking out slightly longer distances. The power, speed, and hill climbing advantages clearly go to the more premium KS4 Pro and its beefy 1000W motor. But the S2 Pro makes up ground with a thinner, lighter, and more portable body. So you’ll need to balance performance needs Vs. portability preference.

Performance And Ride Quality

Now let’s dive deeper into how these aspects of performance and ride experience compare between the two Hiboy models:

Speed

The Hiboy KS4 Pro reVs. up to an ultra fast 25 mph top speed that leaves many rival e-scooters in the dust. This gives you more versatility to zip around town or commute longer distances efficiently.

While no slouch either, the Hiboy S2 Pro has a still very capable but tamer 19 mph maximum. This makes the S2 Pro better suited if you prioritize safety and stability over all-out speed. It may also meet local electric scooter regulations in some areas that limit speeds to 15-20 mph ranges.

Power And Hill Climbing

Powering the KS4 Pro’s speed and excellent handling is its brawny 1000 W motor, which also provides superior hill climbing up to 25% inclines. You’ll have no trouble tackling hilly urban terrain or sections of graded bike lanes.

While the S2 Pro’s 500W motor suffices for most everyday uphill and level terrain at its lower weight and speed ceiling, steeper hills will require more rider effort compared to the KS4.

Ride Comfort And Stability

Complementing their power is equally well-designed framework and running gear that provide stable, balanced rides. The pneumatic honeycomb tires on large 10” rims absorb bumps very well, as do the front suspension on both models.

But the KS4 Pro also adds a rear suspension for maximum vibration damping and improved traction. Both share the same thickness anti-slip standing decks that avoid cramps during long rides.

For even better stability at high speeds, the KS4 Pro runs wider 8.7” rubber with a larger 21.5” deck compared to the S2 Pro’s 5” wide tires and 18” deck. However the S2 Pro still offers a very steady base, just expect it to feel more nimble whereas higher speeds on the KS4 Pro feel more planted.

Braking

Safely harnessing all that speed and power are a pair of redundant stopping systems on both e-scooters: regenerative electric brakes amplified by mechanical disc brakes for sharp, short stops even on inclined roads in wet or dry conditions.

The S2 Pro and KS4 Pro brake levers have integrated electric switches to trigger this blended braking.

Portability

If getting around compactly is important to you besides raw performance, the sleeker and 14 lbs lighter Hiboy S2 Pro has advantages over the larger KS4 Pro

Carrying And Storage

Weighing just 32 lbs, the Hiboy S2 Pro is remarkably easy to carry with its integrated handle and stow away in cars, on public transportation, or in small living spaces. Whereas hauling around the 46 lb KS4 Pro requires significantly more effort and space that could be hard to spare when not riding it.

Folding And Transport

Despite beefier builds, both electric scooters retain folding designs for transportation and storage between rides. The steps to collapse and extend their frames are identical using latches built into their steering columns and decks.

Folded down, the dimensions of the KS4 Pro at 47” x 21.5” x 24” are predictably larger Vs. the more compact S2 Pro’s measurements of 41” x 18” x 21”. So the S2 Pro has an easier time fitting into elevators, lockers, car trunks for multi-modal commuters.

Features And Customizations

Connecting and customizing your rides is essential too. Here’s how the S2 Pro and KS4 Pro compare on useful features that enhance the overall ownership experience:

LED Display Panel

Your ride vitals are clearly visible on the bright LED panels built into the handlebars of both scooters. These display current riding mode and speed, battery level, Bluetooth connection status. The KS4 Pro exclusively adds a trip odometer to track distance traveled per ride or over time.

App Connectivity And Customization

Hiboy’s proprietary app unlocks handy connected features on both e-scooters via Bluetooth. You can get real time ride telemetry, update scooter firmware, customize performance settings like acceleration and braking sensitivity to your preferences, and anti-theft locking.

The KS4 Pro exclusively works with an app dashboard widget to switch between Eco, Standard and Sport riding modes. Sport mode unleashes its full 1000W potential with ultra responsive 25 mph top speeds, while Eco reins acceleration for gentler 18 mph rides that maximize battery efficiency to the 30 mile ceiling. The S2 Pro lacks riding modes but its acceleration is still adjustable in the app.

LED Headlight And Tail Lights

Brightening your path when riding dawn, dusk, night are built in LED head and brake lights on both models. The KS4 Pro adds remarkably bright 2W head and tail lamps so cars and pedestrians spot you clearly from further away, whereas the S2 Pro lights have 1.1W power.

Build Construction

Water and abrasion will inevitably come the way of any outdoor mobility gear. So the entire frames of both the S2 Pro and KS4 Pro are IPX4 water-resistant to withstand light splashes and sprays. Their common materials like aluminum alloy, mechanical plastics and rubber tires resist corrosion and impact damage too.

The KS4 does use thicker aluminum plus more steel components driving its weight but at the benefit of higher durability. Also watch the video!
