Why would Specialized use a different chain ring on the Como vs Vado?
Because they are a global corporation, serving many markets, and their sales planning is poor. This is what I think:
The Vado and Como are probably made in Taiwan. In the marketing/sales planning for the next year, Specialized have to plan how many:
- Euro/Pacific 25 km/h e-bikes could be sold
- Euro 45 km/h e-bikes should be built
- North American Class 1 e-bikes could be sold, especially in Canada (the 20 mph / 32 km/h spec)
- U.S Class 3...
I even don't mention South America or Africa or Asia.
Now, the factories making Vado and Como (I think it is Merida) get the order to make this and this number of e-bikes of this and this spec for this and that market.
If we're talking Europe, there is only a single 45 km/h model, which is the Vado 6.0. It is equipped according to the Euro L1e-B spec and it has the 48T chainring as well as the 1.2
s motor. The Class 3 models dedicated for the United States are Vado 5.0 and Como 5.0: the 1.3 motor and 48t chainring.
Suddenly, Specialized realise they are unable to sell as many Class 1 e-bikes (the 1.2 motor and 40T chainring) as planned but these bikes have been already built. What to do?
"Let us make a double rebate sales in the U.S.! Take the Class 1 Vados, reprogram them to the speed limit of 28 mph, and we'll empty the warehouses!" Does it ring a bell for you?
The 1.2 motor is powerful and it does its work for the Class 3. However, the 40T Vados must be the bikes planned as Class 1 but sold as Class 3 ones. (Why the U.S. Como 4.0 comes with the 48T chainring remains a mystery to me).
@RTeremi, ask your Specialized LBS if they could replace the chainring in your Vado with the 48T one. That should help.
