Bicycles have come a long way since the Penny Farthing, though the general concept hasn't actually changed that much since the 19th century.自行車已經走過了漫長的道路，因為前輪大後輪小，但總的概念其實並沒有發生任何改變，因為19世紀。 The main difference now, you'll be pleased to know, is that bikes are far more comfortable than they were back then!現在的主要區別，你會很高興知道，就是自行車更舒適遠遠比他們回來了！ It's difficult now to imagine a bicycle made out of wood, or solid rubber tires, though I'm sure back then bike manufacturers would not have dreamed a bicycle would have its own suspension either!這是現在很難想像一個自行車由木頭雕刻而成，或實心橡膠輪胎，但我敢肯定，當時自行車製造商也不會想到自行車將有自己的中止其！

One thing which is more difficult nowadays than it was in the 19th century is choosing the right bicycle.有一件事現在更困難比是在19世紀，是選擇正確的自行車。 Bike designs have really evolved, and rather than one bicycle fits all (as was the case back then), there's a variety of different bikes available, suitable for different purposes.自行車的設計真的演變，而不是一個適合所有自行車（如同當年的情況），有一個多種不同的自行車用，適用於不同的目的。

So how do you know what kind of bike will be best for you?所以，你怎麼知道是什麼樣的自行車將最適合您？ Well you first need to start by deciding on what you want yours for.那麼您首先需要首先決定你想要什麼你的。

If it's for a casual jaunt down the road, there's no point in buying a full suspension mountain bike!如果是短途旅遊的休閒在路上，沒有點購買一個完整的懸掛山地自行車！ Equally, a racing bike would be pointless for you too!同樣，賽車是毫無意義的對你呢！ So maybe we should look at what exactly is available on the market.  The four major types of bicycle popular for sale today are所以也許我們應該看看到底是什麼，市場上。四大類型的自行車流行的今天，出售

• racing bicycles,賽車自行車，
• mountain bikes,山地自行車，
• tourers, and旅行車，和
• hybrids.雜種。

Racing bikes 賽車自行車
are designed for speed and aerodynamics, and as such they have dropped handlebars, narrow tires, and little in the way of extras so as to keep the weight down.是專為速度和空氣動力學，因此，他們已放棄了把手，窄輪胎，幾乎沒有額外的方式，以保持體重下降。 These are fine for cyclists who want to cover fair distances at higher speeds, but would be no good for extended cycling trips if all you're relying on is a bike.這些都是騎自行車罰款誰想要支付公平的距離在更高的速度，但沒有好的延長單車旅遊，如果所有你所依賴的自行車。

Mountain bikes 山地自行車
have really risen to popularity in the last decade or so.真正上升到流行在過去10年左右。 Buying a full mountain bike is probably pointless unless you're intending to go tearing up and down mountains!購買一個完整的山地自行車可能是毫無意義的，除非你打算去撕毀上下山！ Mountain bikes have very sturdy and chunky frames, chunky tires, and most these days also have dual suspension.山地自行車非常堅固笨重的框架，笨重的輪胎，而大多數這些天也有雙重暫停。 Importantly they also have very low gear ratios so that riders are able to get up hills effectively.更重要的是他們也有非常低的傳動比，使乘客能夠有效地起床山。 But on the downside, full mountain bikes aren't really very good for cycling on roads because the chunky tires cause a lot of drag.但在下跌，全山地自行車不是真的很好的自行車道路，因為笨重的輪胎造成很大的阻力。

If you're not into hurtling down a mountain, but perhaps want to cycle on a few forest trails, and some roads, a hybrid bicycle is probably better for you.如果你沒有把飛馳下山，但可能要在幾個週期的森林小徑，和一些道路，混合自行車可能更適合您。 These are really a cross between a mountain bike and the old fashioned utility bikes.這實際上是一種跨之間的山地自行車和實用的老式自行車。 It's built to be more practical for a variety of uses – the chunky tires aren't so chunky that you get loads of drag, so they're ok on roads, yet they're chunky enough to handle tracks and light off-roading.它的興建，以更加實際的多種用途-輪胎的大塊大塊的不那麼你得到負載的阻力，所以他們確定的道路，但他們很厚實，足以應付軌跡和輕型越野。 Many of the hybrids now come with front suspension forks, easing the shocks your wrists take if you're cycling on uneven ground.許多混合動力汽車都拿出前懸掛叉，緩解手腕的衝擊，如果你採取單車在不平的地面。

Tourers, 旅行車，
or或 touring bicycles自行車旅遊 , are very popular too. ，也很受歡迎。 These are closest in design to a racing bicycle, but the frames are a little bulkier and heavier because they're designed to be able to handle heavier loads.這是最近在設計的跑車，但幀有點大而笨重的，因為它們被設計成能夠處理更重的負荷。 Tourers come with either straight handlebars or dropped handlebars, depending on your preference, plus an extensive gear range so that you can make it up hills, but also get a good speed going down hills too.旅行車提出要么直接把手或刪除把手，根據您的喜好，以及廣泛的設備範圍，使你可以把它的上坡路，而且還可以得到良好的速度下降山了。 The main feature of touring bicycles is their pannier racks.主要特點的旅遊自行車是他們的儲物架。 These can be front or rear, or both, mounted, and carry specially designed bicycle pannier bags.這些都可能是前或後，或兩者兼而有之，安裝，並進行專門設計的自行車儲物袋。 As the name of this bike suggests, it's designed for touring ie going long distances.正如其名暗示該自行車，它是專為旅遊，即去長的距離。

So those are the big four, and probably the most popular around the world for people who want a bicycle for leisure purposes.因此，這些都是大個，並可能是最流行世界各地的人誰想要單車休閒的目的。 Alternatives include BMX bicycles, Cruiser bicycles, Tandems, Choppers, and fold-up bikes.備選方案包括小輪車自行車，越野自行車，雙人，菜刀，和折疊式自行車。
