The Joy of Folding Bikes

## 折叠自行车的乐趣 作者最近重新发现了他们11年前购买的折叠自行车(Brompton)的好处,并希望他们能更早地投资一辆。 这辆自行车最初是通过“骑行上班”计划购买的,使其价格合理,彻底改变了他们的通勤方式,尤其是在乘坐火车时——即使在“禁止自行车”的政策下,也能轻松放上火车。 主要优点包括防爆轮胎(归功于Schwalbe Marathon Plus)、便携性(单手可提,可放入汽车后备箱)和安全性(易于带入室内,避免被盗风险)。 虽然重点介绍了Brompton,但作者鼓励研究其他品牌。 除了便利性之外,这辆自行车还能节省大量成本——与每天的车站停车费相比,几个月内就能收回成本。 结合Cycle Streets等应用程序进行安全路线规划,以及采取明智的道路安全措施,在像伦敦这样的城市骑自行车变得愉快而高效。 最终,折叠自行车提供了自由、锻炼,以及比以往使用公共自行车计划或传统自行车更愉快的通勤体验。

## 布朗普顿自行车:便利与担忧 一篇 Hacker News 的讨论强调了布朗普顿折叠自行车的吸引力,尤其是在伦敦。用户称赞了它们的便携性——可以轻松带上火车进行一日游,并且方便在城市中出行,而无需依赖公共交通。布朗普顿自行车租赁,提供从自动储物柜租赁的服务,因其自行车本身和合理的价格获得了积极评价,但应用程序因可用性问题而受到批评。 然而,一个主要担忧是盗窃。布朗普顿的受欢迎程度使其成为主要目标,导致车主必须不断监控他们的自行车。这个问题促使一位用户选择购买来自迪卡侬的 менее привлекательный、更便宜的自行车,以避免潜在盗窃的压力。 讨论还包括关于 Y Combinator 2026 年夏季申请期的提醒。

I was chatting to a friend about my folding bike and I had the urge to write about it - because this falls in the category of “Things I wish I’d had decades ago”. And maybe I can encourage some others to try these wonderful devices.

Note: I’m 3 months into a new job so blogging has taken a back seat to drinking from a firehose of new domain knowledge, new people, new tech. I’m still playing with AI-assisted coding, but at a slower pace - I do hope to blog more about this when things calm down.

12 years ago I started cycling in London, commuting by train, and I used the bicycle hire scheme mis-named at the time “Boris Bikes”. It was OK but a bit of a hassle - bikes were heavy, payment was fiddly, and often the hire racks would be empty in the morning and full in the evening.

So I followed the advice of other commuters and got this beautiful device - it cost £1000 at the time, a fair bit of money, but on a Ride to Work scheme I could pay this weekly over a year, so it was £4 a week, pre-tax, which made it quite affordable.

Red Brompton folding bike

It’s a Brompton - and they are a marvellous brand, but I don’t want to just say “Get a Brompton” as I’m sure other brands must be competing in this space - and Bromptons are pricey. So do your own research.

I also (after a couple of annoying flats) got puncture-proof Schwalbe Marathon Plus tyres - and I haven’t had a single puncture since.

And like I said at the start - I so wish I’d had something like this years and years ago. So many years of commuting in Melbourne where I’d walk slowly to a station, or drive to a station and have to cram into busy parking. So many years where my bike would languish in a shed, probably with flat tyres because I only got it out on specific “exercise” attempts.

The folding bike:

  • Lives in my study. I have a nicer bike in the shed but almost never get it out because the bike in my study is so convenient.
  • Can be carried in one hand - it’s heavy, about 12kg plus bags, but that’s ok for short distances.
  • Can go on the train - this is the biggest benefit, commuting is so much easier when you can go cycle -> train -> cycle. Most trains, even ones with “no bikes” rules, allow them - they aren’t any bigger than a large suitcase.
  • Never gets punctures
  • Can go in the boot of the car easily - when I get the car serviced, I drive to the garage, then cycle home, and cycle back to the garage at the end of the day.
  • Can be carried in to the office or cafes or shops - no locking it on the street; a big benefit in London where bike thieves are everywhere and tend to carry bolt cutters or angle grinders!

I do have a lock - a folding ‘silver’ grade Abus Bordo lock that mounts on the bike. But I only really use it in my home town where thieves are much rarer, or on the very rare case where I want to go in a cafe and there isn’t room for the bike - but only if I can sit with the bike in eyeshot!

I get it serviced every year or two. And after 11 years, it’s had nothing major go wrong - a few cable replacements and the like, but it still has the original frame, wheels, and gears. That’s pretty impressive for 11 years of commuting, though post-Covid I only tend to commute one day a week.

For a lot of people this should be fairly should be simple economics. Our station parking is £10 a day - current Brompton prices start at £1400 - so even ignoring pre-tax schemes and savings in other transport like the underground, a Brompton would pay for itself in 140 working days, or 28 weeks for the poor folks still commuting every day.

Plus I just love the freedom of cycling, and the exercise!

#protip If cycling in one of the supported areas the free Cycle Streets app is marvellous. It uses Open StreetMap data so users can update it when roads change, and lets you choose quiet vs fast routes. People ask me if cycling in London is safe - it’s fine if you use an app like this to avoid the worst roads, and ride sensibly with a bit of care about passing trucks or busses, and (gasp) actually obey traffic signals.
