One S1 Couple Riding with wall behind

The cool looking single wheel Segway… Are looking to know more about it and maybe get one for yourself? Your search is over. In this article I will let you know everything you need to know about one of the best single wheeler the market has to offer: The Segway Ninebot One S1, the “big brother” in the one wheel personal transporters arena.

The first and most important thing to say, before we even begin to describe the One S1, is that this is not a transporter for the faint of heart. You will need to invest some hours of training before you can ride normally. But if you have what it takes, if you are bold and love a challenge, the One S1 is certainly your personal transporter. Do you like to try new things, and set yourself apart and be different than the rest? Keep reading and I guarantee you’ll be turning everyone’s heads soon enough!

What is the Segway?

The segway is a self-balancing, battery powered electric vehicle. It was invented by Dean Kamen, and produced by Segway Inc., a US company based in New Hampshire. When turned on, the device is kept upright using computers, sensors and electric motors. The transporter uses gyroscopic and accelerometer sensors to maintain it’s balance, detecting any changes in the pitch angle. The rider controls speed and direction by managing her/his weight over the device.

Aside from being super cool and a great way for personal transportation, a very famous use for the Segways are city or park tours. These tours started almost 2 decades ago and have become really popular. But this is just a curiosity note, as these tours mostly use the two wheel version of the Segway, like the Segway miniPro or Segway I2 SE. If you are interested, you can check this cool company that offer these tour services in several cities:

How to ride the Segway One S1

Before you can ride your One S1 you will need to properly charge it. Be sure to turn the device off before charging it. Also consider to perform a full charge before it’s first use. It’s recommended that you use a power surge protector to keep your unit safe from any surges or voltage spikes in the power line.

To start charging the wheel, plug the power cord into the charging port and also into the surge protector. Now you can plug it to the electric outlet. Be sure to check the voltage of your power grid and the accepted by the device charger (different countries might have different voltages in their power grid).

WARNING: Do not connect the charger if the charge port of the device or the cable is wet.

If you want, you can turn on the One S1 after connecting it to the power, and it will display the charging level in the lights ring. The charging will be done when the LED indicator in the charger changes from red to green. It will take approximately 4 hours to be fully charged. You can top off the charge at any time. The battery charge level appears in the light ring when the One S1 is stationary.

When the batteries are nearly empty, the lights will blink red. You can also use the mobile app to check the remaining charge on the battery and the estimated remaining distance the device could reach.

Prepare yourself for your first ride!

For your safety, the wheel comes equipped with an activation procedure, and also speed and sensitivity limits. The One S1 comes inactive at time of purchase, and the speed and sensitivity are set are low levels.

You must install the mobile app and follow the instructions to activate the vehicle before it’s first use. Please follow these few steps to get started:

Step 1: Download and install the mobile app on your phone / tablet:

Register or login (if you already have an account) using the installed app on your mobile device.

Step 2: Put the vehicle upright and power it on. Turn it off and on again to familiarize yourself with the controls.

Step 3: Click “search device” in the mobile app to connect to your One S1. The vehicle will beep to indicate a successful connection.

Step 4: Follow the instructions in the app.

After performing the previous steps, you should have your One S1 activated. Immediately after activation, the mobile app will guide you through the New Rider Tutorial. Please DO NOT skip the step. It’s vital that you follow along to understand and learn as fast as possible to ride your new personal transporter.

For your safety, the one s1 will limit your max speed to 2.5 mph (4 km/h) before activation. After activation, but before completing the New Rider Tutorial, the max speed will be 4.3 mph (7 km/h). For the first 0.6 miles (1 km) after completing the New Rider Tutorial the max speed will be limited to 7.5 mph (12 km/h). After the first 0.6 miles (1 km) you can disable the speed limiter using the mobile app, and reach a max speed of 12.5 mph (20 km/h).

Becoming a proficient rider can take many hours. Practice each step in the New Rider Tutorial at least 15 minutes each day until you feel comfortable with each specific maneuver. Always wear a helmet and protective clothing when riding. Select an appropriate helmet with a chin strip in place. Bicycle or skate helmets that provide protection for the back of your head are good choices.

You will need access to an indoor or outdoor practice area that has a level and smooth surface with good traction (not slippery!). Do not try your first session in any area where you might encounter children, pedestrians, pets, vehicles, bicycles or other obstacles that might be potential hazards.

Learning to ride and the One S1 basic moves

When you are ready to start, move your One S1 to the center of the riding area that you’ll be using for practice. Keep in mind that learning to ride is a step by step process!

Carefully scan your surroundings. Your eyes are your best tools to evaluate potential hazards and safely avoiding obstacles

Get used to how the one s1 operates with these basic drills:

    • Step on one pedal and swing your leg back and forth gently.
    • With assistance of a friend put one foot in one pedal and gradually shift your weight to the One S1, but keeping your other foot on the ground.
    • With assistance of a friend, put one foot in one pedal, and raise the other feet from the ground for 1-2 seconds.
    • With assistance of a friend, put both feet on the pedals, one by one, and try to move forward and backwards by controlling your center of gravity.
    • To turn, press with one foot hard than the other and shifting slightly your weight.
    • To dismount, be sure your friend is close by. Come to a stop by centering your weight. Then step out and to the back from the One S1.

You’ll need to become very proficient in riding the One S1 before attempting to leave your practice area. The more you practice, the safer you’ll be when riding in new places. Ride in areas free of obstacles and distractions until you are very comfortable with your wheel. Use caution when riding in new environments. Is not unusual to lose your balance when learning to ride. It may take many hours of practice to become a competent rider, so take it easy, one step at a time. You should practice until you can step on, ride forward and backwards, turn, stop and step back as easy as you can walk.

When you are set for the day or reached your destination, and should turn off your One S1. Hold the power button to turn the unit off. A tone will sound, and the power light display will fade out.

It’s important that you develop the habit of maintaining in top condition your wheel, and be safe in every session. Before each ride check your One S1 for loose fastens, any damaged components and low tire pressure.

If the one s1 makes any weird noise or sounds an alarm, immediately stop riding. Contact your dealer or distributor for support and customer service.

Remember to remove the electric cord before performing any maintenance, or installing any part or accessory. Remember to use only approved parts and accessories, and do not modify the vehicle, as they can interfere with the normal operation, resulting in serious injury or damage to the device. The warranty could be voided too.

Important Usage Warnings

Never restart your One S1 after the battery level is indicated in red, nor try to continue using it in this condition. It might not have enough power to keep you balanced. If you restart and continue, you risk falling and injuring yourself and others. You would also risk damaging the batteries, reducing their life and capacity.

Ensure “carry mode” is active before lifting the One S1 by the handle while it’s powered on. Not doing this will cause the wheel to spin and may result in injury or damage to the One S1.

Using the One S1 improperly and not following the provided instructions might result in serious injuries to yourself or others and damages to the device.
