Cyklen repareres på værkstedet i morgen.

In Danish, the present tense is often used for future events when a time expression makes the future meaning clear.

So in:

Cyklen repareres på værkstedet i morgen.

the word i morgen tells you that the action happens tomorrow, so Danish does not need a special future form here.

This is very similar to English sentences like:

• The bike is being repaired tomorrow
• The bike gets repaired tomorrow
• The bike is repaired tomorrow (less common, but possible in scheduled contexts)

Danish can also use vil for future meaning, but it is not necessary here.

Repareres is the passive form of the verb at reparere.

• active: Man reparerer cyklen. = Someone repairs the bike.
• passive: Cyklen repareres. = The bike is repaired / is being repaired.

The ending -s makes the verb passive here. This is called the -s passive.

So:

• reparerer = repairs / is repairing
• repareres = is repaired / is being repaired

Danish has two common ways to form the passive:

1. -s passive
   
   • Cyklen repareres.
2. blive passive
   
   • Cyklen bliver repareret.

Both can often be translated as The bike is being repaired / will be repaired.

In many ordinary factual or formal statements, the -s passive is very common, especially in writing and neutral descriptions.

A rough comparison:

• repareres can sound a bit more neutral, formal, or matter-of-fact
• bliver repareret can sound a bit more spoken and can sometimes emphasize the ongoing event more clearly

In this sentence, Cyklen repareres på værkstedet i morgen is completely natural.

Cyklen means the bike, while en cykel means a bike.

Danish usually expresses definiteness by adding the article to the end of the noun:

• en cykel = a bike
• cyklen = the bike

So the ending -en is the definite article here.

This is one of the biggest differences from English: Danish often puts the at the end of the noun instead of before it.

For the same reason as cyklen:

• et værksted = a workshop / a repair shop
• værkstedet = the workshop / the repair shop

The noun værksted is a neuter noun, so its definite singular ending is -et:

• indefinite singular: et værksted
• definite singular: værkstedet

So på værkstedet means at the workshop / at the repair shop.

This is the normal Danish main-clause word order:

1. subject: Cyklen
2. finite verb: repareres
3. other information: på værkstedet
4. time expression: i morgen

So the structure is:

Subject + verb + place + time

This is a very common neutral order in Danish.

You could move elements around for emphasis, but then Danish still follows the V2 rule in main clauses: the finite verb stays in the second position.

For example:

• I morgen repareres cyklen på værkstedet.

Here I morgen comes first for emphasis, but repareres is still the second element.

På værkstedet means at the workshop / at the repair shop.

Danish often uses på with places where English might use at. So this is very normal.

Compare:

• på skolen = at the school
• på hospitalet = at the hospital
• på værkstedet = at the workshop

English speakers often expect i because they are thinking of physical location in a building, but Danish frequently chooses på for institutions, workplaces, and similar locations.

So here, på værkstedet is the standard choice.

It can overlap with all of those in English, depending on context, but in this sentence the most natural idea is:

• will be repaired tomorrow or
• is being repaired tomorrow in a scheduled sense

Because of i morgen, the sentence clearly refers to a future repair arrangement.

So the best natural English meaning is usually something like:

• The bike will be repaired at the workshop tomorrow.

The Danish present passive does not always match one single English tense exactly.

Yes. The passive leaves the agent unstated.

Cyklen repareres focuses on the bike and the action, not on who does it.

If you wanted to mention the person or people doing it, you could add that information, for example:

• Cyklen repareres af mekanikeren i morgen.
  = The bike is repaired by the mechanic tomorrow.

But Danish, like English, often uses the passive specifically when the doer is unknown, obvious, or unimportant.

Because i morgen is the normal Danish expression meaning tomorrow.

It is written as two words:

• i morgen

Literally, learners sometimes connect it with the preposition i, but as a fixed expression it simply means tomorrow.

You should just learn it as the standard spelling.

A useful comparison:

• i dag = today
• i morgen = tomorrow

Yes, absolutely.

That sentence is also correct and natural:

• Cyklen repareres på værkstedet i morgen.
• Cyklen bliver repareret på værkstedet i morgen.

Both mean roughly the same thing.

A learner-friendly way to think about it is:

• repareres = compact passive form
• bliver repareret = periphrastic passive with bliver

In everyday conversation, many speakers may prefer bliver repareret, while repareres is also very common, especially in neutral statements and writing.

Yes. An active version would name the person or group doing the repair.

For example:

• Mekanikeren reparerer cyklen på værkstedet i morgen.
  = The mechanic repairs / will repair the bike at the workshop tomorrow.

Or more generally:

• De reparerer cyklen på værkstedet i morgen.
  = They are repairing / will repair the bike at the workshop tomorrow.

The passive version is chosen because the important topic is the bike, not who repairs it.

With i morgen, it normally sounds like a specific planned event.

So the sentence suggests something like:

• the repair has been arranged
• the bike is scheduled to be repaired tomorrow
• this is not just a general truth or routine

Without i morgen, Cyklen repareres på værkstedet could be understood more generally depending on context, but with the time expression it clearly points to a particular future occasion.
