Du kan låta cykeln stå kvar vid cykelstället.

Here Du kan can be understood as you can in the sense of it is possible / acceptable for you to.

Depending on context, it may feel like:

• you can = it is possible
• you may = you have permission
• you’re allowed to = a more explicit permission meaning

So in this sentence, Du kan låta cykeln stå kvar... is something like You can leave the bike there or You may leave the bike there.

Låta often means let, allow, or have something remain in a certain state.

In låta cykeln stå kvar, it does not mean let in the sense of giving permission to the bike. It means something more like:

• leave the bike
• let the bike remain
• allow the bike to stay

So låta + object + verb is a very common Swedish pattern:

• låta någon göra något = let someone do something
• låta något stå kvar = leave something standing / leave something where it is

Cykeln is the definite form, meaning the bike.

Swedish often uses the definite form where English might use:

• the bike
• your bike
• it

In context, the speaker probably means a specific bike already understood by both people, so cykeln is natural.

Compare:

• en cykel = a bike (any bike, not specific)
• cykeln = the bike (a particular bike)

Swedish often uses specific position verbs where English might simply use be or leave.

Common ones are:

• stå = stand
• ligga = lie
• sitta = sit

A bike is thought of as something that stands, so Swedish says:

• cykeln står där = the bike is standing there

That is why låta cykeln stå kvar literally looks like let the bike stand remain.

Natural English translation: leave the bike there or leave the bike standing there.

Kvar means remaining, left behind, or still there.

In this sentence, stå kvar means:

• stay where it is
• remain there
• be left there

Some examples:

• Hon är kvar hemma. = She is still at home.
• Låt glaset stå kvar. = Leave the glass there.

So stå kvar is a very useful expression meaning remain standing / stay there.

Vid usually means by, beside, at, or near.

So vid cykelstället means by the bike rack / at the bike rack.

This makes sense because a bike is typically parked next to or at the rack, not literally on it.

Compare:

• vid cykelstället = by the bike rack
• på bordet = on the table
• i garaget = in the garage

So vid is the natural preposition here.

Cykelstället means the bike rack or the bicycle stand.

It is made up of:

• cykel = bicycle / bike
• ställ = stand / rack
• -et = the definite ending for a neuter noun

So:

• ett cykelställ = a bike rack
• cykelstället = the bike rack

This sentence has a verb chain, which is very common in Swedish.

Breakdown:

• kan = modal verb (can)
• låta = infinitive after the modal
• stå = another infinitive connected to låta

Structure:

• Du kan = You can
• låta cykeln = leave/let the bike
• stå kvar = remain standing / stay there

So the full structure is basically:

Du kan + låta + object + stå kvar + place

A useful thing to notice: after kan, Swedish does not use att.

• Jag kan komma. = I can come.

And after låta, Swedish also normally uses a bare infinitive:

• Hon lät honom gå. = She let him go.

That is why you get kan låta cykeln stå kvar with no att.

Yes, absolutely.

Du kan lämna cykeln vid cykelstället means something like You can leave the bike at the bike rack.

The difference is mainly one of nuance:

• låta cykeln stå kvar emphasizes letting it remain there
• lämna cykeln is a more direct leave the bike

So:

• Du kan låta cykeln stå kvar vid cykelstället. = slightly more focused on the bike staying where it is
• Du kan lämna cykeln vid cykelstället. = simpler and more direct

Both are natural, but the original sentence has a nice idiomatic Swedish feel.

The sentence follows normal Swedish main-clause word order.

Parts of the sentence:

• Du = subject
• kan = finite verb
• låta cykeln stå kvar vid cykelstället = rest of the predicate

More detailed breakdown:

• Du = you
• kan = can
• låta = let/leave
• cykeln = the bike
• stå kvar = remain standing / stay there
• vid cykelstället = by the bike rack

So the pattern is:

Subject + finite verb + infinitive + object + second infinitive phrase + place

This may look unusual from an English perspective, but it is a very normal Swedish structure.
