I first had a very old Hawk Trakattak, cost £99 at the time around 89', 90'? It was awfull, but it got me offroad. Had a fair few miles out of it in my mid teens, had 18 gears with plastic, very flexy brake levers, but I had sooo much fun on it! It managed a few rounds on cannock chase then gave up breaking the rear axle. I rode it with a snapped axle for about 5 miles with the tyre rubbing, fixed it then bought others that would cope with proper offroad (Muddyfox Alu Comp) still have both.
