Handlebars
Mountain bike handlebars are angled perpendicular to the ground to allow for riders to press against them while going downhill. Hybrid bike handlebars are often a little higher and angled upward, to allow for a riding stance that emphasizes visibility.
Frame
Mountain bike frames are designed with abuse in mind. Most hybrids could take some light trail riding, but are not meant for sustained shock.
Tires
Mountain bike tires are typically 26 inches in diameter, while hybrid tires are 29 inches to create a more efficient ride on city streets.
Traction
Mountain bike tires are knobby for gripping dirt and rock, while hybrid bike tires are typically designed more for wet-weather traction.
Gears
Mountain biking gears are often designed for more precise work and slower maneuvering. Hybrid bikes often have more gears to choose from when climbing hills or speeding down roads.
