I bought a bicycle.

Today, I went to Køge to buy a folding bicycle from someone.

I found the ad on dba.dk which is a famous Danish website.

(similar to e-bay?)

The price was good, however Køge is too far away from my apartment.

However I thought "It's a good opportunity to go to Køge.

Køge is a very small town but it has a good atmosphere.

(similar as to e-bay?)

The price was good, however the distance from my apartment to Køge was too far.

Also, the train and bus would cost were me a total of 150DKK (30USD).

However, I thought: "This is a good opportunity to go to Køge,

Otherwise because I might not ever go there otherwise." anymore.".

It was a nice short trip as I had imagined. (You originally said you thought it was too far though.)

Køge is a very small town but good has a atmosphere.

By the way, speaking of the herring I ate several days ago, that seems bad already.

(similar to e-bay?) Or: same as e-bay

You ate some herring several days ago but...sorry, not sure what was bad already...
