6. 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.
7. 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.
