In case you plan to buy one and intuition isn’t telling you which one to go for then you can make a decision matrix using the table. A great technique if it’s done well. Click below to see an example.

Lean Machines Decision Matrix

The text below is really important if you’re going to learn to ride a self-balancing scooter. It’s based on my own experiences learning the Hovertrax.

Learning to Ride an Electric Self-balancing Scooter

Self-balancing electric foot scooters are fun and convenient but not as safe as you might think. It’s essential that you master the following steps before even considering riding beside a road, in a busy public place or other challenging environment.
When learning you will need a safe place with lots of space and a large open flat surface such as a running track, the center of a gymnasium, a tennis court or a playground.

Before going out with your scooter
1. Understand the functions
Read the manual and other information carefully and make sure you know how to turn it on, off, and so on.
2. Understand the concept
Before you hop on, be sure you understand the concept of how it works and can visualise how the angles of the feet correlate with speed and turning.
Tilt forward = go forwards.
Tilt back = go backwards.
Right tilt forwards, left back = turn left
Left tilt forwards, right back = turn right
You can practice angling and turning your hands or sit on a chair or edge of a bed putting your feet on the device while it’s switched off pretending you’re riding.

In a safe practice location
3. Getting on
Put your dominant foot level on the scooter and bring the other foot up quickly.
4. Getting off
Step off behind the scooter keeping one foot level on the platform to prevent the scooter rolling away.
5. Stopping
Practice regular stopping as well as abrupt stopping at high speeds. For high speed stopping as you tilt your feet back crouch down with hands level to the ground until you reach a stop. You should aim to be able to come to a complete stop in the shortest possible distance (about 1 to 1.5 m for the Hovertrax at near top speed).
6. Turning
Practice turning on the spot (one foot tilting back, the other tilting forward) and turning at speed (one foot level, the other tilting forward). You could use plant pots or other such objects to form a practice slalom course.
7. Reversing
Practice going backwards.
8. Reversing & turning
Practice going backwards and turning.
9. Stepping off while moving
Many foot scooters may get stuck on rough terrain. To prepare for this learn to step off while going at speed. Be extra careful because if when you step off your foot pushes down on one side of the platform the scooter will move in the corresponding direction. It could zoom out from under your feet or even back under your feet.
Go slowly in a straight line and then while moving take a quick and little step putting one foot in front of the machine resting on your toes with the heel up. Then follow with a larger step with your other foot flat on the ground. The first foot should stabilize you and stop the machine from rolling on as it goes into the sole of your shoe.

Only once you’re ready and have fully mastered the other steps should you very carefully and very gradually have a go at seeing how fast you can go safely maintaining stability. Take multiple goes, each time increasing your speed a little more. Once the speed control tilts you back, or the device strains or wobbles then slow down right away. You must never try to increase the speed beyond this point otherwise the device may not have enough power to keep up with your leaning and you could fall.
At speed you must make absolutely sure that you keep both feet as level as possible on the platforms to keep a straight line.


  1. Understand the concepts and the machine.
  2. Try doing the basic things until they become natural.
  3. Only then progress toward the more advanced things.

Art in Children’s Language Classes

Just remember: kids like games, stories, and cartoons.  If we help children to see learning as fun – as the greatest game – then we’ve already done them a great service.

The great thing about using art in language classes is that students can use and hear a variety of language in the process and it can also help them to achieve a relaxed focus beneficial to learning.  Furthermore auditory and visual tasks are easily performed in unison so as students draw they can still talk or listen to stories and music.  The students generally love it, it can help them to focus, you get some peace, and you’ll probably get very happy parents who have visual proof that their children are actually learning or doing something constructive.  If the artwork can help the World then all the better.  In some cases the artwork can be part of a wider campaign.  For example, in America various schools took part in an anti-idling campaign in which students drew posters, displayed them, and then even went out to remind parents in cars to not idle their engines.

While students create posters I sometimes read aloud stories or articles they have previously learned.  You can also make it a game by pausing in mid-speech.  The student that can recall the next sentence, word or idea can get a point for their team.

Tip: Each student must first create a sketch including all the text in pencil.  Then a teacher checks and only once the teacher says or writes that it’s OK can the student start to use pen.  It’s often good to use plenty of the target language in the artwork, such as in speech bubbles and so on.

Example artwork from English classes:

Feel free to get in touch and send images by your students.  High quality artwork with beneficial messages could be put online.

If you have a school in Hong Kong and would like to hire Luc (the Peacemaker founder) for a poster making session with students then feel free to get in touch.  Free for orphanages, charities, and non-profit organizations.
