wǒmen zài zìxíngchēdào qíxíng.

Mandarin usually puts time and place before the main verb.

So the basic pattern here is:

Subject + location + verb

• 我们 = we
• 在自行车道 = on/in the bike lane
• 骑行 = ride / cycle

So:

我们在自行车道骑行。
= We ride in the bike lane.

If you put the location after the verb, it usually sounds less natural in a basic sentence like this.

Here, 在 is a preposition meaning something like at / in / on, depending on context.

In this sentence:

• 在自行车道 = in/on the bike lane

So 在 introduces the place where the action happens.

A very important point for learners:
this 在 is not the progressive marker meaning be doing. It is simply marking location.

Compare:

• 我们在自行车道骑行。 = We ride in the bike lane.
• 我们在骑行。 = We are riding.

In the second sentence, 在 is before the verb and helps show an ongoing action. In your sentence, it comes before a place noun, so it means location.

Often, yes, 在自行车道上骑行 sounds especially natural.

Both are understandable:

• 在自行车道骑行
• 在自行车道上骑行

But with places that are thought of as surfaces, routes, or areas, Mandarin often uses 上.

So many native speakers would say:

我们在自行车道上骑行。

That said, your original sentence is still clear and grammatical enough for learners.

It is a compound noun made of three parts:

• 自行车 = bicycle
• 道 = lane / way / path

So:

自行车道 = bicycle lane / bike lane

You can think of it as:

自行车 + 道
= bicycle + lane

This is very common in Mandarin: several words combine to make one noun.

Both are possible, but they are a little different in style.

• 骑自行车 = ride a bicycle

  • more literal
  • very common for everyday learning and speech

• 骑行 = cycle / ride

  • more compact
  • a bit more formal or written
  • often used in signs, articles, rules, or sporty contexts

So:

• 我们在自行车道骑行。 = We cycle in the bike lane.
• 我们在自行车道骑自行车。 = We ride bicycles in the bike lane.

Both make sense, but 骑行 sounds slightly more concise and polished.

Yes. 骑行 can function as a verb meaning to ride or to cycle.

It is made from:

• 骑 = to ride
• 行 = to go / travel

Together, 骑行 means traveling by riding, usually on a bicycle or similar vehicle.

So in this sentence, 骑行 is the main verb.

Mandarin does not use articles like a, an, or the the way English does.

So 自行车道 can mean:

• a bike lane
• the bike lane
• bike lanes

The exact meaning depends on context.

In your sentence, English might translate it as the bike lane or just bike lanes, but Chinese does not need a separate article word.

Mostly yes, but there are a couple of things to notice.

• 我 = I / me
• 们 makes it plural for people
• so 我们 = we / us

One thing English speakers sometimes ask about is whether Mandarin distinguishes inclusive we and exclusive we. Standard Mandarin 我们 does not clearly mark that difference by itself. Context tells you whether we includes the listener.

So 我们 can mean:

• me and you
• me and some other people, not you

depending on the situation.

No, even though it looks similar in pinyin, it is pronounced differently.

• 我 = wǒ (3rd tone)
• 们 = men (neutral tone)

So 我们 is pronounced roughly like:

wǒ men

The wo part does not sound like English woe, and the whole word is definitely not the same as English women.

Also note that 们 here is usually light and unstressed.

Here are the tones:

• 我们 — wǒmen → 3rd tone + neutral
• 在 — zài → 4th tone
• 自行车道 — zìxíngchēdào → 4th, 2nd, 1st, 4th
• 骑行 — qíxíng → 2nd, 2nd

So the full pinyin is:

wǒmen zài zìxíngchēdào qíxíng

A learner tip: say it in chunks:

我们 / 在 / 自行车道 / 骑行

That makes it easier to keep the tones and rhythm clear.

Yes, it is understandable and fairly natural, but it sounds a bit more formal or written because of 骑行.

In everyday speech, people might more often say:

• 我们在自行车道上骑车。
• 我们在自行车道上骑自行车。

These sound a little more conversational.

Your original sentence:

我们在自行车道骑行。

is perfectly good, especially in written Chinese, public safety language, or explanatory material.

Usually, no. If you want to say where the action happens, 在 is normally needed.

• 我们在自行车道骑行。 = correct
• 我们自行车道骑行。 = not natural

So 在 is important because it clearly marks 自行车道 as the location.

A useful pattern is:

Subject + 在 + place + verb

Your sentence fits that exactly:

• 我们 = subject
• 在 = location marker
• 自行车道 = place
• 骑行 = verb

So you can make similar sentences:

• 我们在公园散步。 = We take a walk in the park.
• 他们在教室学习。 = They study in the classroom.
• 我在路上跑步。 = I run on the road.

This is a very common and important Mandarin sentence pattern.
