when did the self balancing scooter come out
Self-balancing scooter Invented in its current form in early 2013, the device is the subject of complex patent disputes. Volume manufacture started in China in 2014 and early units were prone to catch fire due to an overheating battery which resulted in product recalls in 2016, including one of 500,000 units sold in the United States from 8 manufacturers.
Crash/ride cymbal A ride/crash cymbal is similar in design and function to a crash/ride, but slightly heavier and/or less tapered to optimise the ride rather than the crash function. It is far less common than the crash/ride.
