Wow! I want one! This is such a nice product. I can imagine my youngest son riding the stroller while I'm pedaling. This is such a good combination.
Pros:

• multi-functional
• very convenient
• it converts stroller into bike, and vice versa, in a matter of seconds
• nice design
• exercise while bonding with your child, who wouldn't say no right?
• user-friendly

Cons:

• none
