As we know, it is easier to have heat from mechanical, electrical, chemical energy.
According to thermodynamics, there should be more complex devices for transferring heat to be kinetic energy in reverse.
Hundreds of parts in a car to integrate an auto machine for moving, there is still half heat waste through cooling & exhaust system.
Compared to Internal Combustion Engine, EV is simple to get electricity from chemical energy efficiently based on electrochemical process. The parts and maintenance are less accordingly.
All the industry products are assembled via modules mostly for effortless maintenance following from good system design in whole process.
Therefore E-bike is easier in maintenance and parts replacement than motorcycle.
