When buying a scooter, it's essential to consider factors like budget, intended usage, and type of scooter. Set a budget that includes not only the purchase price but also ongoing expenses such as maintenance and energy costs. Determine your primary use, whether for commuting, leisure, or off-road adventures, and consider the terrain, distance, and portability. Choose between gas-powered, electric, kick, or mobility scooters based on your needs. Also, assess engine or motor power to ensure the scooter meets your requirements for speed, range, and terrain adaptability.
