Yes . Should 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 rush hour .

Maybe you should think about getting a round helmet ; they're better .
happiness
user
I'll think about 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 ?

user
Well , my saddle is too low for me . Do you know how to change the height ?
neutral
assistant
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 ?
