I'm planning to buy a bicycle . As you are quite a cycling enthusiast , I wish you might give me some advice .   With pleasure , chap . But before I start , I need to know what you want a bike for ?   My purposes are two-fold . On the one hand , I've grown bored of commuting on suffocating buses every day and decided to ride to work . On the other hand , bicycling is a sport , and I intend to build up my body through constantly taking a ride over the weekends .   Cycling during weekends ? Do you me riding on the mountainous countryside just the neighboring towns ?   Does that make any difference ?
