are you ready to go the concert?
yes. Shoud we go there by bus so we aren't late?
actually, why don't we go there by bike? We could get stuck in traffic if we travel by bus in ruch hour.
that's true. Cycling is good for our environment, too. Let me just get my helmet then.
is your helmet comfortable?
not really, but I liked the design, so I got it.
maybe you shoud think about getting a round helmet; they're better.
I'll think about it.
is that your new bicycle?
yes, my father gave it to me for my birthday. Do you like it?
it's the newest 10 speed cycling mountain bike. These are really expensive!
nothing but the best from my dad. I like everything about it except for the brakes. They are a bit sticky.
I can fix those for you. Is there anything else wrong with it?
well, my saddle is too low for me. Do you know how to change the height?
that's easy. It's important to have the saddle high enough so that your legs can extend fully when you are on your bicycle.
is that why my knees have felt sore after every time I've ridden my bike?
