Interesting Points• When I went around the corner on my old bike on the way to the letter box, I skidded because there was to much weight on my old bike.• I knew my GT would be the quickest because it suits me and fits me better than the other bikes.
Was my Prediction Correct?• My new bike was the quickest because my old bike is too small for me and I need to grow bigger before I can ride mums bike properly.
