Here is an upgraded and corrected version of your text in English: The bike is in perfect condition and has only been used for occasional rides in Richmond Park, resulting in very low mileage overall. I have consistently maintained it in excellent condition, with professional cleaning and servicing at the shop every 6 months. After every ride, I lubricate the chain, and it's always stored indoors in a private garage. It performs perfectly for me; I am selling it because I am moving to a new city and unfortunately cannot take it with me. Nonetheless, it's a great bike.

New tire covers and a new chain have been installed. The transmission was replaced six months ago. I have conducted regular checks, cleanings, and servicing every six months since I purchased it, always following the shop's recommendations for upgrades and changes.
