Hiboy S2 Electric Scooter Review: The Commuter’s Tank or a Bumpy Ride?

Quick Verdict

Rating: 4.3/5

The Hiboy S2 is the Honda Civic of electric scooters. It isn’t flashy, and the ride can feel stiff on rough pavement, but it is reliable, affordable, and gets the job done. I found the solid tires to be a blessing for maintenance but a curse for comfort. If you ride on smooth city bike lanes, this is the best value you will find. If you have to ride over cobblestones or deep potholes, your knees will hate you.

Key Specs (S2 Model):

• Top Speed: 19 mph (Verified)
• Real-World Range: 12–14 miles (Claimed 17)
• Weight: 31 lbs

Best For:

• Rider Height: 5’1″ – 6’2″
• Rider Weight: Under 200 lbs for best performance (Max 220 lbs)
• Commute: 2–6 miles on paved roads

Avoid If:

• You weigh over 230 lbs (Speed drops significantly)
• You have back problems (The ride is stiff)
• You ride on gravel or dirt

Who This Scooter Is Best For

Budget-Conscious Commuters

If you need to get to work or class and don’t want to spend $800+, this fits the bill. It pays for itself in Uber savings within three months.

College Students

It fits easily under a dorm bed or a desk. The locking mechanism via the app is decent for quick stops, though I always recommend a U-lock.

Flat-City Dwellers

Riders in places like Phoenix or Florida will love this. The lack of hills makes the battery last much longer.

Who Should Avoid This Scooter

The Heavy Duty Rider

While it says it supports 220 lbs, I felt the motor struggle on inclines when I loaded my backpack up. If you are 240+ lbs, you need a 500W motor minimum.

The “Cloud” Seeker

There is no air in these tires (on the standard S2). You feel the road. If you want a plush ride, look for a scooter with 10-inch pneumatic tires and dual suspension.

Pros & Cons

How I Evaluated This Scooter

I didn’t just read the spec sheet. I took the Hiboy S2 out on the cracked streets of my city, rode it through a college campus, and tested it on a 15% incline hill. I weigh about 185 lbs. I carried a backpack weighing 15 lbs during testing to simulate a real commute.

I tested the brakes in an emergency stop scenario at 15 mph. I also drained the battery from 100% to dead to see the actual mileage, not just what the box says. My goal was to see if this scooter falls apart after a month or if it keeps ticking.

Build Quality, Design & Durability

Frame Strength & Materials

The stem and deck are aluminum. It feels substantial. When I stepped on it, there was no flex in the deck. It feels like a tank. Some budget scooters feel like toys; this feels like a tool. The matte black finish looks professional, though it scratches if you clip a curb.

The Folding Mechanism

This is a mixed bag. The latch at the base of the stem is solid. It snaps shut with a reassuring click. However, the way it stays folded is annoying. A hook on the handlebars clips onto the rear fender.

Here is the problem: It relies on tension. If you pick up the scooter and the stem tilts back slightly, the hook pops out. I had the deck swing down and smack my shin twice before I learned to keep upward pressure on the handlebars while carrying it. It is a design flaw. It works, but you have to be careful.

Display & Buttons

The dashboard is simple. Speed, battery bars, and mode. You can read it in direct sunlight, which surprised me. One button does everything.

• One click: Light on/off.
• Two clicks: Eco/Sport mode.
• Long press: Power.

Tires & Wheels (The Controversy)

The standard S2 uses 8.5-inch solid honeycomb tires. They have holes drilled through the rubber to provide “give.” They are durable. I drove over glass and didn’t flinch.

Note on the S2 MAX: The MAX model has 10-inch tires. The rear tire on the MAX often houses the motor and is inflatable. I have seen reports, and my experience confirms, that changing a flat on the rear motor wheel of the MAX is incredibly difficult. You have to strip wires. Bike shops often refuse to do it. If you buy the MAX, use slime sealant immediately.

Long-Term Durability

After weeks of riding, the fender started to rattle slightly. This is common. A quick tightening of the screws fixed it. The folding hinge needs to be tightened every few weeks or the stem develops a wobble. Hiboy includes the tool. Use it.

Ride Comfort & Handling

The Solid Tire Reality

Let’s be honest. Solid tires are a trade-off. You trade maintenance for comfort. On smooth asphalt, the S2 glides. It feels fast and nimble.

On brick paths or cracked sidewalks? It vibrates. My hands felt buzzy after a 3-mile ride on bad pavement. The S2 has rear dual shock absorbers. They help a little. They take the edge off big bumps, but they don’t stop the high-frequency vibration from rough roads.

Stability at Top Speed

At 19 mph, the scooter feels planted. The battery weight is in the deck, keeping the center of gravity low. I never felt “speed wobbles.” However, because the tires are solid, you have to be careful turning. Solid rubber does not grip as well as air-filled rubber. If you lean too hard into a turn on a wet road, the back end will slide out.

No Suspension Reality Check

The “suspension” is just springs in the back. The front relies entirely on the tire. If you hit a deep pothole, you will feel a jarring impact through the handlebars. You learn to scan the road ahead very quickly.

Performance: Speed, Acceleration & Hills

Real-World Top Speed

I hit 19 mph consistently on flat ground in Sport mode (red S on the display). It takes about 6–7 seconds to get there. It isn’t a drag racer, but it’s faster than most rental scooters like Lime or Bird, which are often capped at 12–15 mph.

Acceleration Feel

The 350W motor has decent torque. It doesn’t jerk you back, but it doesn’t lag either. You can adjust the acceleration strength in the app. I cranked it to max. It feels zippy.

Hill Climbing Ability

This is where physics takes over.

• Flat Ground: 19 mph.
• 5% Grade (Overpass): Dropped to 16 mph.
• 10% Grade (Steep Driveway): Dropped to 11 mph.
• 15% Grade (San Francisco style): It crawled at 6 mph. I had to kick to help it.

If you live in a very hilly area and weigh over 180 lbs, the standard S2 will struggle. The S2 MAX with the 500W motor handles hills much better, maintaining 14–15 mph on those same grades.

Kick-to-Start

By default, you have to kick the scooter to 3 mph before the throttle works. This is a safety feature so you don’t accidentally launch it across the room. You can turn this off in the app to enable “Zero Start,” but I recommend keeping it on. It saves battery and is safer.

Battery Performance & Charging

Real-World Range

Hiboy claims 17 miles for the S2. Manufacturers always test with a light rider on a flat track at slow speeds.
Here is my real data (185 lb rider, Sport Mode, Mixed Terrain):

• Mile 0-5: Full power, 19 mph.
• Mile 5-9: Still strong, hits 18 mph.
• Mile 10-12: Noticeable power drop. Top speed drops to 15 mph. Acceleration is sluggish.
• Mile 12.5: Dead.

I reliably got 12 to 13 miles. If you put it in Eco mode (10 mph limit), you might hit 17 miles. But nobody rides in Eco mode.

The S2 MAX Range

The S2 MAX claims 40 miles. Expect to get about 25–28 miles in real-world conditions. That is still huge. It means you only charge it twice a week instead of every day.

Charging Time

The charger gets warm, which is normal. The S2 takes about 5 hours to charge from empty. The light on the brick turns green when done. The charging port is high up on the stem, near the handlebars. This is a smart design. It keeps the port away from water and dirt on the ground.

Braking & Safety

Brake Types

The S2 has a dual system. The left thumb lever controls the electronic regenerative brake (front wheel). The hand lever controls the rear mechanical disc brake AND triggers the front regen brake.

Emergency Stopping

This is the S2’s superpower. The brakes are strong. Almost too strong. If you grab the hand brake tight, the rear wheel will lock up and skid. You have to learn to modulate it. I stopped from 19 mph to 0 in about 15 feet. That is excellent.

Lighting Quality

• Headlight: It is mounted high. It projects a decent beam, but it’s more for being seen than seeing far ahead. In pitch black, I would want an extra bike light.
• Taillight: Flashes when you brake.
• Deck Lights: There are red LED strips along the side of the deck. I love this. It makes you look like a moving spaceship at night. Cars seeing you from the side is a huge safety plus.

Water Resistance

It has an IP54 rating. This means “splash proof.” I got caught in a light drizzle, and it was fine. Do not ride it through deep puddles. The motor and battery are sealed well, but water can ruin the bearings over time. Also, solid tires on wet metal plates (like construction covers) are like ice. Be extremely careful in the rain.

Portability & Daily Use

Folding Speed

It takes 3 seconds. Unlatch, fold, hook. Done.

Carrying Weight

At roughly 31 lbs, it is manageable for one flight of stairs. It isn’t “light,” but it isn’t a 50 lb beast. The balance point is right in the middle of the stem.

Public Transport

I took this on the bus. It fits between your legs if you sit. It fits under the seat on the subway. The handlebars do not fold down, so it stays somewhat wide (about 17 inches). If the train is packed, you might annoy people.

Storage

It stands upright with a kickstand. The kickstand is a bit small. If you park on a slope, it can tip over. I wish the kickstand were wider.

Common Issues & Maintenance

The “E2” or “E7” Errors

Some users report error codes. E7 usually means a motor hall sensor issue. This sounds scary. However, Hiboy support is surprisingly proactive. If you email them a video of the issue, they usually send a replacement part or a whole new scooter if it’s new.

Tire Changes (S2 MAX Warning)

I cannot stress this enough. If you get the S2 MAX, fear the rear flat tire. The motor cable connects to the wheel. You cannot just pop the wheel off like a bike. You have to disconnect the wires inside the deck. It is a 2-hour job. The standard S2 does not have this problem because the tires are solid.

Loose Screws

Vibration loosens bolts. Buy a tube of Blue Loctite. Put a drop on the four screws in the handlebar and the screws in the folding mechanism. Do this on day one. You will thank me later.

Long-Term Ownership Expectations

Battery Life

After 6 months, expect about 90% of the original range. Lithium batteries degrade. Do not leave it plugged in for days. Do not leave it in a freezing garage all winter. Treat the battery well, and it will last 2–3 years.

Tire Wear

The solid tires last forever. The tread eventually wears down, making them even more slippery in the wet. Check the tread depth every few months.

Maintenance Costs

Zero. That is the beauty of the S2. No oil changes, no filters, no inner tubes. You might need to adjust the brake cable tension (easy to do with a wrench), but that’s it.

Final Verdict: Is It Worth Buying?

If you have $400 to spend and need a way to get around the city, the Hiboy S2 is a fantastic choice.

I recommend it because it removes the biggest headache of scooter ownership: maintenance. You unbox it, charge it, and ride it. You don’t have to check tire pressure. You don’t have to worry about glass in the bike lane.

Yes, the ride is bumpy. Yes, you have to tighten the screws occasionally. But for the price, the speed and reliability are unmatched.

Buy the S2 if:

• You commute under 10 miles round trip.
• You want to save money on gas/rideshare.
• You are handy enough to tighten a screw but hate changing tires.

Buy the S2 MAX if:

• You weigh over 200 lbs.
• You have hills on your route.
• You need to go 20+ miles without charging.

Skip both if:

• You ride on cobblestones or dirt paths. The vibration will drive you crazy.
