I am 14 years old and run a lawn business around my nieghborhood. I am in need of help with the transportation of my supplies, so I am interested in buying a bike hitch (TRAILERON), and using either a wagon on home built storage space to transport my stuff. However, I think I might want to buy a new bike before I begin hauling this stuff. Does anyone have any suggestions or bike recomends? My budget is limited.
