Can the hydrogen and oxygen released by electrolyzed water drive motorcycles? If so, tell me what to do.

It is possible in theory, but it is unnecessary in practice. For example, a battery can store 1 kwh of electricity, and electrolyzed water will lose some energy after heating, and then it will only have 0.9 kwh of electricity, and then hydrogen will be converted into motorcycle power, which will be less than 0.5 kwh. Now the conversion rate of internal combustion engine is less than 50%. If the motor is directly driven, 0.9 kWh can be converted into kinetic energy.
