12 speed: good to go just about everywhere except very steep hills. The range of different ratios are more than enough for most people. There are 2 front chain rings and 6 rear gears. - Derailleur: Shimano Tourney
Tires 24 x 1.75: medium width tires with small thread, for comfort on asphalt and occasional off-road.
