The point here is that it is quite common for an employer to provide transportation. It is confusing why the OP need to personally buy a bike to ride quickly around to observe fires. If riding around is part of the job, often times the employer will provide the equipment necessary to do the job- thats why it matters who pays.
But since the OP's job makes little to no sense so far, all this is pretty pointless back and forth.
