[speaker001:] are you ready to go the concert?
[speaker002:] yes. Should we go there by bus so we aren't late?
[speaker001:] actually, why don't we go there by bike? We could get stuck in traffic if we travel by bus in such hour.
[speaker002:] that's true. Cycling is good for our environment, too. Let me just get my helmet then.
[speaker001:] is your helmet comfortable?
[speaker002:] not really, but I liked the design, so I got it.
[speaker001:] maybe you should think about getting a round helmet; they're better.
[speaker002:] I'll think about it.
[speaker001:] is that your new bicycle?
[speaker002:] yes, my father gave it to me for my birthday. Do you like it?
[speaker001:] it's the newest 10 speed cycling mountain bike. These are really expensive!
[speaker002:] nothing but the best from my dad. I like everything about it except for the brakes. They are a bit sticky.
[speaker001:] I can fix those for you. Is there anything else wrong with it?
[speaker002:] well, my saddle is too low for me. Do you know how to change the height?
[speaker001:] 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.
[speaker002:] is that why my knees have felt sore after every time I've ridden my bike?
[speaker001:] it's possible. Give me a minute and I can fix these for you and then we can go.
