I believe in bicycles
I believe in riding my bike to the store,
riding to work, riding for fun, fitness and adventure -
Road bikes, mountain bikes, single-speeds, you name it.
As long as it has two wheels and a human motor, I'm on it.
And I truly believe, deep down in my easily misdirected soul,
that the world would be a better place if
more people rode bicycles.
