For speed enthusiasts, the famous Trinx road bike 21 speeds 27.5 size Aluminum frame and rims Original gear shifting system Rear tire to withstand greater weight Wide brake pads 4 brake handles for two riding positions New breathable sports seat The bike, praise be to God, has no issues. I bought it for weight loss, but unfortunately, I couldn't ride it due to lack of time and laziness on many occasions... Please do not bargain, especially those who do not understand bikes.
