Trek 3 series hardtail mountain bike for young teenagers. It has 26” wheels and it’s frame is 13” (33 cm), alpha silver aluminum. It is is pretty good condition, has brand new handlebar grips, a kick stand and a bottle holder. The paint is shipped in some places and the suspension is used, however, I tightened the brakes and they have no trouble and I oiled up the gear shifter and it changes gears easily. Overall it was a great bike but is too small for me now.
