Will my bike be assembled? What is the difference between the Base service and the Ready-to-Ride package?
Your bike will be partially assembled. You can choose between two services when ordering your bike, this will determine how much your bike will be assembled when delivered.
Base Service
When you choose the Base service, you will receive the bike as we get it from our sellers.
The assembly requirements can vary based on the manufacturer and seller. Some tasks, such as connecting cables, registering the gearing, and adjusting the brakes, will need to be done manually by you.
Professional mechanic intervention is recommended for proper assembly and safety.
Ready-to-Ride Package
When you choose the Ready-to-Ride Package up to 80% of the bike components will be pre-assembled upon delivery. You will only need to make final adjustments to the handlebar, front wheel, and seat post.
This option significantly reduces the time and effort required to get your bike ready for use.
Do I have to pay import fees/VAT/GST on top of the final price?
For orders delivered in the EU, VAT and GST are always included in your final cart price.
For orders delivered in the United Kingdom: we offer Delivered Duty Paid (DDP) shipping, meaning tariffs and customs clearance fees are already included in your final cart price. You won't face any additional charges upon delivery—what you see is what you pay.
Exception for UK bid orders: If you buy a bike through our bidding system and the delivery address is in the UK, standard Delivered at Place (DAP) terms apply, meaning you'll be responsible for tariffs and customs clearance fees upon arrival.
For orders delivered in all other countries worldwide: we ship using DAP terms, which means you'll be responsible for paying any - if applicable - tariffs and customs clearance fees when your bike arrives in your country. These fees are not included in your cart total and will be collected by the courier or customs authorities upon delivery.
For orders picked up in-person: products with SKU number starting with "BK" - and other selected bikes - can be collected directly from our headquarters in Milan. If you're exporting the bike outside the EU within 90 days of purchase, no local VAT or taxes will apply. You must declare the export and handle import procedures at the country of destination customs office. Please note: it's not possible to have your order shipped to a European country and export it later—tax-free purchases require in-person pickup only.
