Fitness Bikes: Mountain Fitness Hybrid Bike. Here at Higher Gear we have all your fitness hybrid bike needs, from Specialized to Scott to Bianchi. Fitness hybrid bikes come with 700c wheels that are a touch wider than a traditional road bike tires. These tires are more resistant to flats and have more traction – a must have if you want to ride on rougher roads or a crushed limestone-like trail. Fitness hybrid bikes are great for people that want an efficient bike but don’t want the dropped body position. Some of the great features of fitness hybrid bikes are: • Disc brakes. These are great for riders who ride year-round, or those who are going to ride in rougher conditions. • Ergonomical grips. These take out some of the vibration your hands and shoulders feel from the road.
