  • Mongoose Tyax
    Love the bike, solid but narrow frame, gears are well spaced out so great for trails but still easy to throw round the forest. Seat is pretty awful on the long trips but will upgrade soon enough. Over all i do reccomend the Tyax. However, picked up xmas eve and the bike was assembled terribly. Chain snapped on first ride, derailleur was way off position, brakes were real noisy, was lucky the chain broke as i was heading into the hills - if i had gone down the hills i would have lost my wheel as hub and wheel were not secured tightly. Found that out when i took it to my local shop and owner did a full service and check up and explained the "lack of" assembly. Cost me $60 but it has never gone better. Love riding it now.
