it doesn't, in fact it makes it harder. Inertia resists change, so it makes it a bit difficult to get the bike moving.
inertia
When you ride a bicycle, the force of the wheel against the earth causes the earth to push back on the wheel, propelling the bike forward, according to Newton's law of equal and opposite reactions. If the force exerted by the earth is strong enough, it can overcome the inertia of the bike.
Moment of Inertia is defined as the product of mass and square of distance from its axis of rotation and it is denoted by I. I=mR2 Moment of Inertia depends upon mass from the axis of rotation of wheel rim e.g because the mass of big bicycle lie away from the axis of rotation of wheel rim.So M.O.I of big bicycle is Small than small Bicycle.
A combination of inertia and centrifugal force. The wheels, once rotating, create centrifugal force which in conjunction with gravity cause the bicycle to move forward creating inertia. the more energy put into the bike via the drivetrain, the more inertia is created and the more stable the bike becomes.
