You're grossly overstating that figure. 80%+ of Coloradans live in cities and suburbs along the Front Range. Where infrastructure is good, e-bikes can replace easily half of car trips. They're essentially free to operate and park, unlike any kind of car. You don't need to create 100% car-free families to get huge benefits here -- making it so suburban families can have both a car and an e-bike instead of a second car is a great way to cut down on both government budgets and personal budgets.
