Peace be upon you. A new Trekx M136 bicycle, used for only 3 months. Everything in it is sound. The tires have been replaced, the brakes have been replaced, everything has been fixed. The only thing is that there is grease from the oil I used to put on the chain to make the bike lighter. The bike has 6 speeds, 3 on the right and 3 on the left. Every time you shift, the pedal changes and becomes stronger. A flawless sports bike. Contact via WhatsApp only (( Phone number appears when clicking the contact button ) )
