Adult mountain bike for commuter (Fortuna/eureka area)

A few years ago I backed up over my husbands nice mountain bike and we were never able to get it fixed! He would be able to especially use one now to commute to his new job with the school district so that the kids and I can have our car. Needs ‘mountain bike’ tires because we have a long dirt driveway before the county road.... Thank you for considering!!! Can pick up anywhere in Norhum or Sohum! (Our cal poly kid could do an Arcata pick up for us they say!)
