It means the bicycle parking area at the station.

• 駅 = station
• 駐輪場 = bicycle parking area / bike parking lot
• の links the two nouns, so 駅の駐輪場 means the station’s bike parking area or the bike parking area at the station

In natural English, at the station is often the best translation.

の connects one noun to another.

In this sentence:

• 駅の駐輪場
• literally: station + ’s / of + bicycle parking area

So の shows a relationship between the nouns. Depending on context, it can mean things like:

• possession: Y’s X
• location/association: X at Y
• type/category: Y-type X

Here, it shows association or location: the bike parking area belonging to / associated with the station.

は marks the topic of the sentence: what the sentence is about.

So:

• 駅の駐輪場は = As for the station bike parking area, ...

The rest of the sentence says something about that topic:

• 朝とても混みます = it gets very crowded in the morning

Using は gives the sentence a general, descriptive feeling. It sounds like a statement about the usual condition of that place.

Because time words like 朝 often do not need a particle.

So both of these are possible in Japanese, depending on the word and context:

• 朝、混みます
• 朝に混みます (less natural here)

With common time expressions such as:

• 今日 = today
• 明日 = tomorrow
• 朝 = morning
• 毎日 = every day

Japanese often leaves out に.

In this sentence, 朝 simply means in the morning.

とても modifies the verb 混みます.

• 混みます = gets crowded / is crowded
• とても混みます = gets very crowded

So とても works like very in English.

混みます is the polite ます-form of 混む（こむ）.

混む means:

• to be crowded
• to become crowded
• to fill up with people or vehicles

In this sentence, it means the bicycle parking area is very crowded in the morning, or gets very crowded in the morning.

Both English translations can work:

• The station bike parking area is very crowded in the morning.
• The station bike parking area gets very crowded in the morning.

Japanese often does not force the same distinction that English does.

混む can describe a state or a repeated tendency:

• is crowded
• gets crowded
• becomes crowded

In a sentence like this, the meaning is usually habitual:

• In the morning, the station bike parking area gets very crowded.

That sounds natural because the sentence is describing what usually happens.

The readings are:

• 駐輪場 → ちゅうりんじょう
• 混みます → こみます

Full sentence reading:

• えき の ちゅうりんじょう は あさ とても こみます。

Yes, somewhat.

Japanese sentence order here is:

• 駅の駐輪場は = topic
• 朝 = time
• とても = adverb
• 混みます = verb

So the structure is roughly:

• As for the station bike parking area, in the morning, it gets very crowded.

English usually sounds more natural as:

• The station bike parking area gets very crowded in the morning.

Japanese often places the verb at the end.

It normally describes a usual or general situation.

Because it uses the non-past polite form 混みます without any special markers, it often means something like:

• It gets crowded
• It is crowded
• It tends to be crowded

So the sentence suggests a regular pattern: the station bicycle parking area is crowded in the mornings.

No. 駐輪場 specifically means a place for bicycles (and sometimes similar two-wheeled vehicles, depending on context).

Compare:

• 駐車場（ちゅうしゃじょう） = car parking lot
• 駐輪場（ちゅうりんじょう） = bicycle parking area

So this sentence is definitely about bike parking, not car parking.
