で marks the place where an action happens, so 店で means at/in the shop.

When は is added, では gives that location a topic or contrast nuance. So この店では means something like:

• as for in this shop...
• at this shop, ...
• in this shop, at least...

In this sentence, では helps set up the shop as the context and can also imply contrast with other places.

Both are possible, but they feel a little different.

• この店で中古の自転車も売っています。
  = more neutral: They sell used bicycles at this shop.

• この店では中古の自転車も売っています。
  = puts more focus on this shop as the topic or contrast:
  At this shop, they also sell used bicycles.

So では can suggest something like:

• speaking of this shop
• in this particular shop
• unlike some other places, here...

この is a determiner, which means it must come directly before a noun.

So:

• この店 = this shop
• この自転車 = this bicycle

You do not use の after この when it directly modifies a noun.

Compare:

• この店 = this shop
• これ = this one

So この works like English this before a noun.

Here, 中古 means used / secondhand, but grammatically it behaves like a noun in this structure. When a noun modifies another noun in Japanese, の is often used.

So:

• 中古 = used goods / secondhand
• 中古の自転車 = a secondhand bicycle / used bicycle

This is similar to:

• 日本の車 = a Japanese car
• 木の机 = a wooden desk

So the の connects 中古 to 自転車.

Not in the same way as a regular -i adjective like 高い or a -na adjective like 静か.

中古 is basically a noun, but it can modify another noun using の:

• 中古の車 = a used car
• 中古の本 = a secondhand book

So even though it translates like an English adjective, in Japanese it is commonly used as a noun + の.

も means also or too.

In 中古の自転車も, it is attached to 中古の自転車, so the meaning is:

• used bicycles too
• used bicycles as well

This implies that the shop sells other things too, and used bicycles are one more item among them.

So the sentence is not just saying they sell used bicycles. It is saying they also sell used bicycles.

〜ています does not only mean an action happening right now. With many verbs, it can also describe a continuing state, a habit, or a regular activity.

Here, 売っています means something like:

• they sell
• they are selling
• they carry for sale

It suggests this is part of the shop’s normal business.

If you said 売ります, it could sound more like:

• will sell
• sell (as a general statement, less focused on the ongoing situation)

In store descriptions, 売っています is very common because it expresses that the item is available there.

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

In this sentence, the seller is understood to be:

• the shop
• or the people at the shop

So English may need a subject like they or the shop, but Japanese does not.

This is very normal. A natural English translation might be:

• This shop also sells used bicycles.
• They also sell used bicycles at this shop.

Japanese is basically an SOV language, which means the verb usually comes at the end of the sentence.

So the order is often:

• topic / setting
• object
• verb

Here:

• この店では = at this shop / as for this shop
• 中古の自転車も = used bicycles too
• 売っています = sell / are selling

This final-verb pattern is one of the most important differences from English.

Yes. 売っています is in the polite ます style.

The plain form would be:

• 売っている

So:

• この店では中古の自転車も売っている。
  = plain style
• この店では中古の自転車も売っています。
  = polite style

The polite version is very common in everyday conversation, explanations, and customer-facing language.

The spaces are usually just for learners.

Normal Japanese writing does not normally put spaces between words like this:

• この店では中古の自転車も売っています。

Japanese is normally written without spaces, and readers identify the word boundaries from grammar, kanji, and context.
