Thank you, I live in an area where the terrain is pretty flat, but I'm still not sure what Vado to purchase@Laurobb: It is worthwhile to mention that in case you like Vado 3.0, the (extra) faster charger alone costs US$200. Specialized is not a cheap company...
While I am very happy with my Trek Allant9s I will spend considerably less for the second bike. I want a Class 3. Specialized seems to offer more for the money.
