I bought a Cube bike to send to Russia. The guys have a very good selection of bicycles for every taste, color and wallet size. There is a parking lot nearby to drive in by car. The staff is very friendly and make a lot of gifts when buying a bike (for 150 Euros it turned out). Now the off-season discounts are 20%. In total, it turned out to be 30% cheaper than ours + gifts. I did not make a tax refund because now everything over 300 euros is blocked at customs.
Please note that the car for transportation should be roomy enough, I had a Volvo XC40, there was enough space, but without a reserve.
Air transportation was done by Air Serbia. You need to book transportation 24 hours before departure and this is only possible for tickets with luggage. In this case, the weight of the luggage and the bike are combined and should not exceed 23 kg. It's free. If this is not done, then you can pay at the airport counter for an additional place for the transportation of sports equipment, the cost will be 100 Euros.
It is advisable to strengthen the bicycle box with adhesive tape at the corners.
