zitensyaten wo otozurete, zyousyatekiousintyou wo kakuninsita sueni, tuukinyouzitensya ni kimeta.

In Japanese, some verbs that involve visiting or leaving a place still use を.

Here, 訪れる means to visit, and the place being visited is marked with を:

• 自転車店を訪れる = to visit a bicycle shop

So even though 自転車店 is a place, it is still the grammatical object of 訪れる.

This is similar to other verbs such as:

• 公園を散歩する = to stroll through a park
• 家を出る = to leave the house

A learner might expect に because English often uses to or at with places, but Japanese grammar follows the verb’s pattern, not the English preposition.

訪れて is the て-form of 訪れる.

The て-form is often used to connect actions in sequence. In this sentence, it links the first action to what comes next:

• 自転車店を訪れて、
• having visited a bicycle shop, ...
• more naturally: visited a bicycle shop and ...

So the sentence flows like this:

1. visited a bicycle shop
2. checked the recommended rider height
3. eventually decided on a commuter bicycle

The て-form does not by itself show tense clearly; the tense is usually understood from the whole sentence and the final verb.

乗車適応身長 is a technical noun phrase, probably something you would see in product information.

It can be broken down like this:

• 乗車 = riding
• 適応 = suitability / appropriate range
• 身長 = height

So it means something like:

• recommended rider height
• suitable height range for riding
• height range appropriate for this bicycle

This is not the kind of phrase learners usually meet in everyday conversation, but it is very plausible in a bicycle store or catalog.

Because 〜た末に adds a special nuance that simple 〜て does not.

• 確認して just means checked and then...
• 確認した末に means after checking and considering, and as the result of that process...

So 末に suggests there was some process, thought, or effort before the final decision.

In other words:

• 確認して、通勤用自転車に決めた = checked it and chose a commuter bike
• 確認した末に、通勤用自転車に決めた = after checking it all carefully / after going through that process, ended up choosing a commuter bike

This gives the sentence a more deliberate, considered feeling.

末に means something like:

• after ...
• as the result of ...
• in the end, after a process

It usually follows a verb in the past/plain form or a noun plus の:

• 考えた末に = after thinking it over
• 相談の末に = after discussion

It often implies:

• time passed
• some effort or consideration happened
• the final result came at the end of that process

So in this sentence, 確認した末に suggests that the decision was not completely immediate; it came after checking and considering the height suitability information.

With 決める, Japanese often uses に to mark the option that was selected.

So:

• Aに決める = decide on A

Here:

• 通勤用自転車に決めた = decided on a commuter bicycle

This is a very common pattern. For example:

• 青に決めた = I decided on blue
• この店に決めた = I decided on this store
• 電車で行くことに決めた = I decided to go by train

So the に marks the final choice.

通勤用自転車 means a bicycle for commuting.

It is made of:

• 通勤 = commuting
• 用 = for use in / intended for
• 自転車 = bicycle

So:

• 通勤用 = for commuting
• 通勤用自転車 = commuter bicycle / bicycle for commuting

This Noun + 用 pattern is very common:

• 仕事用パソコン = work computer
• 家庭用ゲーム機 = home-use game console
• 子ども用の椅子 = chair for children

It is a compact and very common way to express purpose.

Japanese often leaves out the subject when it is obvious from context.

So even though English would normally say:

• I visited a bicycle shop, checked the recommended rider height, and decided on a commuter bicycle

Japanese can simply say:

• 自転車店を訪れて、乗車適応身長を確認した末に、通勤用自転車に決めた。

The subject is understood from the situation. This is extremely normal in Japanese.

A learner should not assume the sentence is incomplete just because no pronoun is shown.

In Japanese, connected actions often rely on the final verb to establish the overall tense of the sentence.

Here:

• 訪れて = te-form, linking action
• 確認した = past form, because it modifies 末に
• 決めた = final past-tense verb

The whole sentence is understood as describing past events.

A rough structure is:

• visited a bicycle shop,
• after checking the recommended rider height,
• decided on a commuter bicycle

Japanese does not have to repeat the same tense marking on every linked verb in the same way English might.

Yes, 自転車店 is normal and means bicycle shop/store.

You could also hear:

• 自転車屋 = bicycle shop / bike shop

The difference is mostly in tone:

• 自転車店 sounds a bit more neutral, formal, or business-like
• 自転車屋 sounds more casual and everyday

In a written sentence like this one, especially one with technical wording such as 乗車適応身長, 自転車店 fits well.

It is understandable and grammatically fine, but it sounds a bit formal and written because of words like:

• 訪れる
• 乗車適応身長
• 末に

A more everyday spoken version might be something like:

• 自転車屋に行って、適応身長を確認した上で、通勤用の自転車に決めた。
• or
• 自転車屋で身長に合うか確認して、通勤用の自転車に決めた。

So the original sentence is not wrong, but it has a somewhat stiff, explanatory, or written style.

No, standard Japanese normally does not use spaces between words.

The sentence would usually be written like this:

自転車店を訪れて、乗車適応身長を確認した末に、通勤用自転車に決めた。

Spaces are often added in teaching materials to help learners see word boundaries more easily.

So the spaced version is for readability, not normal native-style writing.
