It's cheaper than a normal road bike...
This past weekend I witnessed hundreds of people compete in a triathlon, each of them riding a bike that probably had tires more expensive than my bike. The top men and women were riding $10,000+ bikes. And they all own multiple $$$ bikes, specialized to the particulars of the course they're racing.
A $2000 Peloton that you can train in for recovery or when the weather is bad? That's a bargain by comparison.
