Kross first service: distinguish the calendar appointment from zero preparation
Kross first service dates should be read alongside the purchase paperwork, rather than confused with the seller's initial preparation. The Polish manufacturer's help gives a calendar window, a winter-purchase exception and a later inspection period. These are published Kross terms to check for applicability, not a warranty promise from BestBicycle.
Put Kross first service on the right calendar
The help answer says the first inspection should fall between the thirtieth and sixtieth day after purchase. For bicycles purchased from November through the end of January, it says the inspection may instead take place by 31 March at the latest. Keep that stated seasonal exception with the standard window instead of silently deleting either.
Base a service-booking enquiry on your own purchase, even when the model is Kross BERG 3.0 Bike — Black Glossy. Retain the actual purchase date and seller details. A local model listing does not demonstrate that its purchaser has the same contract, documents or service arrangements described on Kross.pl.
Do not mistake zero preparation for that appointment
In a separate help answer, Kross defines przegląd zerowy as the seller's preparation of the bicycle for riding, including assembly and adjustment. That describes work before the handover. It is not the same event as a later inspection calculated from the purchase date.
Ask which preparation was completed and keep the answer apart from the future service booking. If an invoice or handover note merely says the bicycle was prepared, request clarification instead of assuming it also records the first required inspection.
Keep the later inspection visible too
The same service help gives the next periodic inspection as between the eleventh and sixteenth month from purchase. It names authorised Kross service points or Kross sales points as places where inspections may be carried out and directs readers to the warranty statement for the required dates.
Confirm the terms that apply to your actual purchase with the responsible seller or manufacturer. The historical FOCUS image shows a mechanical bicycle, but its appearance cannot establish a purchase date, a service entry or eligibility under Kross terms. The Kross introduction supplies background rather than an individual service history.

FAQ: Preparation and calendar dates
What is the standard first-inspection window on the help page?
It states the thirtieth through sixtieth day after purchase.
Which purchases receive the stated March exception?
The page names purchases from November through the end of January.
Does seller preparation prove that a later inspection happened?
No. Preparation and a subsequent inspection are different events to document.
Arrange Kross first service using the applicable paperwork and a confirmed appointment. The Kross owner guides keep broader model questions separate from those purchase-specific terms.
