A few months ago, Graham Hill (the founder of the site you're reading this on) asked me for some help inchoosing an electric bike。我想帮助,但我知道我的知识有限 - 有这么多的模型,在电池技术和电力电子中一直在进行进展 - 所以我向他指出了一个我知道的人:法院黑麦,e-bike demigod后面ElectricBikeReview.com。但格雷厄姆的问题也让我意识到他当然不是唯一试图弄清楚的人是否适合他,是什么是利弊,如果它确实有意义,那就开始了哪个模型先看看。

这导致了以下采访,法院慷慨地分享来自审查300+型号的电子自行车智慧,因为他开始于2012年覆盖了这个空间(多产的家伙!)。我的问题是粗体:

Why would anyone want an electric bike?

Well, electric bicycles offer the same great benefits as traditional bicycles including cost savings (no licensing or insurance required), improved health and connection with community.

The real advantage to ebikes in my view is efficiency in climbing hills or fighting the wind combined with better range. If you experience knee pain or exercise induced asthma for example, electric bikes can breath new life into the sport of cycling. They might convince your friend or significant other to join you on the trails more often or they might enable you to commute to work in extreme heat without perspiring so much. I've owned cars and mopeds before and neither felt as safe or refreshing as cycling along community paths, away from traffic.

Electric bikes remove many of the roadblocks and challenges that people face with traditional pedal-powered cycles but they aren't perfect. They can be expensive, complex and heavy which is a real pain if the battery runs out half way.

What types of riding are e-bikes best for? What are theyfor?

自美国电动自行车的早期(1999年从Lee Iacocca从1999年开始,从Lee Iacocca开始)框架款式和驱动特性真正增殖。

除了简单的DIY套件外,还有像Ridekick Power Trailer这样的系统,现在除了存储实用程序之外还添加了EBIKE性能!特别是该系统甚至比安装套件更容易,并且可以在家庭成员和朋友之间轻松分享使用常规自行车或靠卧式作为平台。

今天,它可以首先进入选举ric bikes or dip your toe in for a little taste. In some towns you can even rent electric bike to get a better feel for them... Rocket Electrics in Austin Texas for example, offers foodie tours and also has a multi-day SXSW and F1 race week package for people who want to dodge traffic and get an up close view of the city. For the purest experience, purpose built ebikes are the way to go (bikes that were designed and sold as being electric, not converted later). They are lighter, tougher and more capable than ever. Whether you need a folding bike to stow in your loft or take on a plane, a tandem to rent and ride with your friend on vacation or a downhill bomber for free riding on mountain trails (no need for a chairlift!) there is definitely an ebike out there that's fully capable.

Obviously, I'm a huge fan of the technology and it's true that the breadth of products has grown thanks in large part to widespread acceptance in Asia and Europe but there are some things ebikes still struggle with.

如果您是一个纯粹的山地骑​​自行车的骑士,距离徒步旅行的途径勉强接受,Ebikes似乎可能是一种威胁。与80年代的Ebikes中的Vail Colorado这样的滑雪胜地曾经在滑雪胜地被禁止的滑雪板上仍处于早期。最终滑雪板成为主流,伯顿通过推出一个病毒倡议具有挑战性的持有度假村来获得群众接受。这些天,鹿谷犹他州仍然是一个“仅限滑雪”的度假胜地,但你可以在其他地方滑雪,我觉得它也会成为ebikes的情况。一旦技术更好地理解并赞赏,它不会感到如此威胁到某些人。我认为传统的自行车坦率地令人敬畏,我仍然拥有一个沉默,轻度巡航。

To be honest, I mostly use it on wet and snowy days or when parking overnight in high-crime areas where theft or vandalism could be a risk. That said, I recently picked up bicycle insurance (辐条保险和扫地管offer it in almost every state and it covers electric bikes) and am feeling a lot more comfortable from a theft and liability standpoint. To sum up the cons of electric bikes: they tend to be heavier, louder and almost always more expensive than traditional bicycles.

What are the different kinds of electric bikes and their price ranges?

迄今为止审查了300多个电动骑自行车,为每次拍摄照片和拍摄视频,并在我的网站上发布ElectricBikeReview.comthese are the primary "use cases" I've identified to help people navigate the space: Cargo Hauling, Relaxed Cruising, Trail Riding, Mountain Biking, Downhill, Neighborhood Use, Kid Hauling and Grocery Getting, Road Bike, Sand and Snow (Fat Tire), Tandem, Touring or Trekking, Traveling (Folding) and Urban Commuting.

有些场合,有些人有一辆自行车,有些有很小的车轮,旨在容易拾取并携带火车和公共汽车(如果电池超过300瓦特,则甚至是飞机),而其他型号几乎如摩托车或摩托车,具有100+英里的范围能力和再生制动。

现在有很多类型的轻型电动车辆,我实际上开始了第二个网站ElectricRidereView.comto cover electric motorcycles, skateboards and kick scooters. As far as traditional ebikes, prices really vary and can be shocking at first... so brace for impact! The low end starts around $1,000 but a recent crowd funding campaign generated a lot of attention by offering a bare bones $700 model (it was sold as $500 + ~$200 shipping).

我的感觉是1,500美元是现在最值得探索的最低水平。我已经看到了在网上购买的客户太多的客户,现在正在努力修理油门机制或找到替换电池组,因为它们所获得的细胞质量非常低。当廉价电池损坏时,甚至有一些火灾,没有电子管理系统,以防止过载。在Ebike World的上部梯队,有50k美元的产品销售,但这些几乎就像艺术。

对于〜4,000美元,您可以获得高品质,欧元验证,德国工程产品,拥有两年的全面保修支持。像这样的自行车提供直观的控制,综合动力灯,挡泥板和机架以及整体美观的美学。

这家高级级别的自行车范围可达7,000美元,适用于Pro-Level组件,而这可能会震撼一些人,它实际上从Pro-Level踏板动力自行车上不远。

现在让我们回到中间范围,更深入地挖掘成本。我购买的第一辆电动自行车是2,500美元,它在第一年拯救了2,000美元的停车场(我正在奥斯汀市中心,德克萨斯州停车场非常昂贵)。

在YouTube评论中,我经常看到被电动自行车的高价感到不安的人,声称二手车会更便宜......我认为他们经常无法认识到汽车维修的高价格,防止储能等防止养护,保险,保险,保险,许可和停车。汽车和ebikes不是投资,它们是贬值使用的工具或玩具,他们的真实价值高度依赖于手头的环境和任务或娱乐偏好。

So for example, if you live on a highway and commute 20 miles to work each day an ebike might not be a great tool. To that I say, consider renting an apartment near your job and buying an ebike!

抛开生活变化,让我们做一个快速假设的成本调整例子,如果你把所有的汽车维修措施赶走了一会儿,刚刚看了3K全新的汽车与3 00美元的全新的ebike和每加仑2美元的左汽油......平均电动自行车获得〜20英里,填充的费用低于0.15美元(甚至使用夏威夷的规模速度为0.37美元/千瓦时)。所以让我们说你的车每加仑30英里,每加仑是2美元,你的自行车得到20英里,收费为0.15美元,自行车是更便宜的方式?但那不是整个故事。优质电动自行车电池的价格从500美元到800美元替换,持续1,000多美元,所以让我们像燃料成本一样对待这一点,除以500美元/ 1,000美元的费用......我们得到0.50美元。因此,我们将$ 0.15的收费支出加入0.50美元的电池使用费用,并获得0.65美元。

Basically, electric bikes are about three times less expensive to operate than cars from a current fuel cost perspective. Beyond user operating expense they also cost less in terms of negative externalities because they don't create localized pollution which contributes to health issues and spoiled views of the mountains. Ebikes are awesome but so are cars and even when self driving electric cars replace the costs of ownership and reduce pollution, there will still be enormous health and social value to cycling... and why not have an assisted cycle?

这就像比较机械打字机,在那里你强力推动到现代笔记本电脑的钥匙,可以更容易,更快,更快地在更多环境中进行操作,并将其数量保存!也许有些人会声称旧式的打字的纯粹肌肉乐趣和拼写错误的危险将永远持有他们的心中的一个地方......对他们来说有好处,这并不是一个问题和ebikes或传统自行车仍然可以骑在一起,玩得开心!

How far can you typically go on a charge?

A good rule of thumb here is to divide watt hours by 20. So electric bike batteries have voltage and amp hours and a typical pack right now in the US is 36 volts of power with 10 amp hours of capacity for 360 watt hours total. If we divide 360 by 20 we get 18 miles. Given variation between throttle only electric bikes and pedal assist that 18 is really a floor that can go up as riders contribute pedal-power to the system or different drive systems are leveraged.

例如,mid-drive电动自行车可以受益from driving the rear cassette and gears to empower the motor for improved efficiency. In the same way that you would want to shift down when climbing (instead of standing up and working extra hard), so too does the motor and these mid-drive systems offer that flexibility because they pull the bicycle chain along with you. I've seen some electric bikes with that same "360 watt hour" battery capacity reach 50+ miles per charge on a low level of assistance (equivalent to half of the rider's pedal power output). That's pretty amazing to me.

Are e-bikes much faster than regular bikes?

不是真的,大多数低速电动自行车单独在电机功率下每小时超过20英里。您可以随时比踏板更快或落下陡峭的山坡,但联邦调节限制了这种最高速度,以换取分类为“自行车”。最近的一些妥协已经制造,脚蹬辅助电动自行车可能达到每小时达到〜28英里,但只有骑车者严格踩踏。欧洲存在类似于称为“Speed Pedelecs”的类似电动自行车,并成为通勤者的流行。

然而,注意效率显着下降,因为骑手因拖动而获得速度。这是“力作用与相对于周围流体移动的任何物体的相对运动相反”或者在这种情况下。将物体通过流体推动物体所需的功率随着其速度的立方体而增加,而“空气阻力”近似与速度平方成比例。

In short, as you go beyond 15 mph on an ebike, drag really starts to cut into the range you can achieve so speed comes at a high price!

即使它是电动,我还能在自行车上做DIY维护,或者我需要看到专家吗?

This is a great question! When it comes to electric bikes I usually recommend that people buy locally if possible. This is because the bike will be assembled properly, following specific torque ratings on screws and such, and will be fit to the rider for improved comfort.

在自行车行业中,许多销售传统和电动的商店会告诉我Ebikes看到的10次。这是基于客户的反馈和它们提供的调整。人们只是乘坐电动自行车更多,进一步骑,更快!其中一些佩戴可以由最终用户提供服务,但是当涉及节流时,电池和计算机系统的东西可能会变得棘手。

电动自行车用软件和电气复杂地嫁给机械系统。有一个原因是苹果称他们的技术支持“天才”,对吧?在我看来,需要先进的知识和特定的工具集,以确保电动自行车。不提供扭矩传感踏板辅助,液晶显示屏读数或框架路由电缆的最基本的自行车可能是自维修或简单的一次性,但鉴于其较低的价格点,但更具目的地的产品非常受益于该专业触摸和经常次已锁定计算机,具有特殊的诊断工具,如汽车。

您是否有任何最喜欢的E-Bikes型号,您将推荐电子自行车Newbies先查看?

我花了很多时间回答了一次性问题"Compare" sectionof the Electric Bike Review Community Forums where people share their budget, height, weight, intended use and style preference. Feel free to jump on over and ask for yourself! Alternatively, I've put together a这里列出“十大”列表that has actually grown to 26 models for 2014-2015 as I now recommend a value and performance model in 13 categories ranging from Cruisers to Kits. Bikes that I've actually purchased for myself over the years include the Pedego City Commuter, Easy Motion Neo Jumper (now replaced by the Evo Jumper) and the Haibike XDURO FS RX 27.5 but I've been eyeing the new Specialized Turbo X and Felt Outfitter which are remarkable because both companies are long standing purists that focus on performance and racing specs. Seeing them put out electric bikes is a real vote of confidence for the space.

任何结束的想法?

我认为电动自行车是显着的,因为它们与他人联系在一起时恭维人体和思想。

If you'd like to learn more on the topic feel free to download my ebook called "A Practical Guide to Electric Bikes" on Amazon Kindle. The book includes photos, videos and a deeper look into topics like motor design so you can better understand the trade offs between hub motors like I had on my Pedego or mid drives like I had on my Haibike. Feel free to drop me a line anytime and ride safe out there! Oh, and if you or a friend never learned how to ride a bicycle then看看这个额外的视频,我用我的30个朋友拍了它,这是一个从未学过的朋友,就像他错过了。
