How do I learn to balance on a segway?
user
It’s very important to practice and learn from a trained instructor when you’re first learning to ride a segway.  Once you get the hang of it, you can do many things by using wheelies and balancing on one wheel, which allows you to drive very precisely.  The best way to learn is to spend around 15 minutes riding every day for at least 3 weeks, starting slowly and building up to more difficult riding.  You should probably choose an empty area with grass and a large empty space for practicing, and practice on a flat surface only until you gain more experience.  Good luck!

I’m actually not very familiar with the segway, but if you’re interested in learning how to balance on one, it definitely seems like you would want to practice balancing on a safer, simpler device first.  While riding a bike is probably the best overall introduction to balancing on different surfaces, walking on top of a piece of plywood would also likely be a useful skill to build up.
