With the 450, since the owners are our earliest customers who helped us along the journey, we had complimentary plans for the first year, some getting Ather One, and some getting Ather Service.
With the new subscription plans (99k + Plus/Pro performance packs), the monthly subscription fee comes bundled with Ather Charge (Offering connectivity, OTA updates, data storage and pipeline maintenance costs, and unlimited Ather Grid charging). If you’ve pre-ordered the collector’s edition, we’re also offering one year free servicing for your 450X.
We are also working on Ather One/Charge/Service/Connect equivalent plans for the 450X and will announce them soon. We realized there we confused you all with the pricing and didn’t want to complicate that with more numbers 
I’ve added more details comparing the Subscription plans and upfront pricing here:
