An adjustable bicycle frame for change in the riding modes is provided with a bottom bracket secured to pedals; a seat tube extending upward out of the bottom bracket; a chain stay extending rearward out of the bottom bracket and the seat tube; a rear wheel rotatably secured to the chain stay and contacting the ground; a head tube with a stem pivotably secured thereto; a fork pivotably secured to the head tube and extending downward; a front wheel rotatably secured to the fork stay and contacting the ground; a rearward inclined telescopic tubing including first and second tubes. After changing length of the telescopic tubing, a length between the front wheel and the rear wheel is changed, an inclined angle of the seat tube is changed, and an inclined angle of the head tube is changed coherently, thereby implementing a racing mode or a slow, urban riding mode.
