[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 rush 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.
