自行车商店—Bicycle Shop（在线收听）

I've decided to start mountain biking to get in shape and enjoy the scenery around my area, so I took my bike into a cycling shop to get a tune up. My bike was in pretty bad shape, so I wasn't sure if it would serve my needs. However, the man at the shop adjusted my brakes, oiled the chain, fixed my flat tire, and adjusted the spokes in my wheels. He suggested that if I do a lot of heavy riding, I should get self-sealing bike tubes that don't puncture as easily over rough terrain. I'm thinking about getting a lighter bike, but my current bike will have to do for now. I also bought a new bike helmet to protect my head in case I fall off the bike or fly over the handle bars on my rides. Finally, I bought a water hydration backpack so I can drink water and still have my hands free to ride.
