Do it yourself – immediately


Stop right there. Yes, you with the hammer and screwdriver. Don’t you know how dangerous it is doing home improvements? What do you mean, you’d rather be putting up shelves than pedalling into town? Clearly you’ve not read my latest short story, A Risky Ride, which is now available as an eBook on Amazon. So do as I say, put down those tools, get online and order it now.

I don’t read reviews


… but in this case I’ll make an exception! My essay about the mysterious epidemic of cycling injuries, Breaking with Tradition, has received its first review by a reader.

Knowing that the style of my essay was out of the ordinary, I’ve been worried that it might not be well-received. People get used to reading a certain attitude, structure and content and my essay definitely does not follow any of those patterns found in my book. It could easily upset those who might have expected more of the same.

So I’m relieved by what a reader has posted on the essay’s page on Amazon UK website (click here for links to the right Amazon page in other countries). Here’s the review:

‘Not quite what I was expecting from the author of “Cycling Science”, but highly entertaining none the less. No deep enquiry here into the physics of two-wheeled transport, rather a mix of autobiographical recollection, humour and skulduggery. A fun bedtime read. Let’s hope this essay is just the first of a series.’

Not bad for my first essay. It’s enough to make me want to sit on my handlebars and pedal backwards.

Linking with Precision


You’re trying to download my newest essay but can’t find the link, right? I’ve discovered that Amazon has several different ones to my downloadable essay, depending on which of their international sites you are using.

To help you get to the one that’s in your virtual neighbourhood, here are as many of the Amazon links as I can find. I’ll add more as I find them but they are very similar to each other so you might be able to guess the right one for your country:

Breaking with Tradition

Breaking the mould

For several months I’ve been sitting on a few stories that have caught my eye while scouring academic studies relevant to cycling. They are a bit off-track, not solid cycling, excursions from my usual direction, so I couldn’t think which of my usual magazine and web publishers might want them. That’s why I’ve decided to publish themselves myself. But how?

The easiest way to publish an essay so that lots of people can read it is to post it to a blog, such as this. Unfortunately that wouldn’t help me to pay my bills. So, with some reluctance, I’ve chosen to use Amazon’s eBook platform.

The platform really is more suitable for longer works, books, but it might work for the couple of thousand words of an essay. In my next post you’ll find links to the essay on several of Amazon’s international sites and in their local currencies.

Whichever currency you use, I hope the text gives you value for money for what is, after all, something to enjoy over a coffee or even a cup of tea. Or both.

Breaking with Tradition” is the first essay and is available online . It’s an easy read, has some shocking moments and silly recollections. I hope you like it.

No excuses


Hmmm. It’s more than three years since my last post. If you’ve been waiting on tenterhooks and checking back every day then I admire your patience but, honestly, you should seek help.

However, if you’ve been busy like me with other things, please don’t worry that I’m going to keep you here for very long. It’s just to say that during the intervening 40 months, cycling hasn’t stopped nor has science and, consequently, neither have I.

I gave a few talks, chaired the odd conference, wrote a lot of magazine and website articles, sat back in awe as publishers in several countries translated and published new language versions of my book and led some very popular cycling science rides with my mate Derek for the national science festival.

And I’ve been tweeting like there’s no tomorrow (which is always a worrying possibility). Oh, and I revised the UK version of my book and it’s now out in paperback.

I said I wouldn’t keep you for long this time. Hope to see you before another three years pass by. Until then, buy my book, read my articles and wave to me as I pedal past on my way to another laboratory.

Catching up


It’s been a while since I posted anything so I’d like to thank all of my readers, both of them, for being so patient. The reason for the hiatus is that I’ve been writing for a host of magazines, instead.

The magazine list includes, in alphabetical order, Alphr, Bicycling, Bikes Etc, Cycle Sport, Cycling Active, Cycling Weekly, Cyclist and mbr.

If you want to check them out, some of the stories are online. For example, you can see my recent story for Bicycling here.

My contributions to Bikes Etc and Cyclist are online here and there may be more in a few weeks so keep checking back.

And there are a lot of shorter pieces of mine on Cycling Weekly’s website here.

You can read some of my bike-related articles on Alphr here.

The other magazines are not published freely online, although subscribers can download digital versions.

Top tip: Some public libraries in the UK also make digital versions of cycling magazines available to their members for download for free!

I’m still tweeting like crazy about any and every science paper that is related to cycling. I haven’t gone away. I won’t go away. There’s just so much going on that it’s hard to keep up.

A little learning in Oxford


1902981_960111807345477_7702756648112225286_nStill learning. That’s my lesson from the Cycling Science tour in Oxford on the longest day of the year. Even though I’d led it a few times before in other cities and thought I knew it all, I came away knowing even more.

It may have been the lovely bunch of riders who came along – all ages, all genders, all kinds of bikes.  It may have been the lovely route plotted by Science Oxford. It may have been the lovely weather.

Whatever the trigger, there was a moment on the tour when I gained a little bit more understanding about how best to demonstrate some of the science that makes cycling magic. So it’s not just the lovely riders who discover stuff, en route, from the demonstrations and experiments.

Of course, having written a book about Cycling Science, I’d cockily thought there was nothing else to learn.

To write it, I’d read hundreds of thousands of words from hundreds of papers and synthesised them into 192 lovingly illustrated pages.

Yet, to really understand bicycles and the science that makes cycling work, you’ve got to get hands-on, feet on and, yes, bum on, too.

So it was that, during one of the demonstrations, I had a small epiphany.11146479_960111707345487_154455016948870744_n

All the demos and experiments had pretty much worked at each stop on our way to Aston’s Eyot. Then, nervously, I tried to show how the lowest spoke in a wheel gets slacker and carries less load than the other spokes.

I was worried because it hadn’t worked very well on some of the other tours I’d led.

But, in that verdant glade not far from the city centre, on a blazing afternoon on the longest day of the year, it worked perfectly. I became midsummer merry.

The lesson for me was when I realised why it had worked. Unwittingly, I’d used a wheel with spokes laced radially. Prevously I’d always used the more common type, with tangential spokes.



The difference it made to the lovely bunch of riders may have been small. The difference it made to me was enormous. A key point about wire-tensioned wheels had been made clearly and I had learned something new – to always use a radial wheel for that particular demonstration.

To describe the demonstration in detail here would be to spoil the surprise for future Cycling Science tourers. And really, it is an adventure that has to be hands-on, feet on, and, yes, bum on, too.

Naturally I’ll be very happy to bring the new improved resoundingly fantastic demonstration with the radial wheel and the entire tour to everyone who wants it. Drop me a line to book your tour.

And, when that happens, which I hope will be soon, I look forward to learning yet more from the whole experience.

City of Dreaming Tyres


What did I know of Oxford before my visit last Friday? I wore a dubious pair of Oxford bags in the ’80s and that was the sum of it. Now I know a bit more and it’s a revelation.

2933777_1023_2First, there’s The Story Museum. Why aren’t all libraries and museums like this, including those aimed at grown-ups? These beautifully-designed rooms will spur you to read any book, immediately.

As it is, the next Cycling Science presentation will be held there at 6.30pm on Sunday 21 June. I’m privileged to share the bill with Dr Tom Cohen, deputy director of the Transport Institute at UCL.


Tom will give an evidence-based presentation about danger, risk, responsibility and, er, helmets. Yes, helmets. So expect a lot of fireworks. I might have to hide under the giant bed in the room upstairs.

I’m planning to include brand new information about a recently-discovered material that could have as big an impact on bicycles in the 21st century as carbon fibre did in the 20th and steel did in the 19th.

You’ll have to come to the talk to find out if you’ve guessed correctly.

There will also be a couple of Cycling Science Rides during the day. I’m indebted to Tara at Science Oxford for showing me the paths and tracks past the river and through meadows of this surprising city.

Cycling Science the Ride-2Compared to previous Cycling Science rides, these will be positively rural, despite being in the centre of a conurbation. Tara’s picked out a great route and, as ever, they will be family-friendly.

If you think you know HOW a bicycle works, these rides, complete with demonstrations and experiments, will show you WHY a bicycle works. We even dreamed up a couple of new stunts to open your eyes to the magic that is cycling.

There will also be an opportunity to purchase signed, discounted copies of Cycling Science, my book which has grown into live talks, led rides and helped me to discover Oxford.

I hope to see you there.

Roll up, roll up: Nutrition, Colnago, Aerodynamics & Himalayas


I’ve got my work cut out this month, preparing for several gigs at Edinburgh International Science Festival and Chester University.

None of them will be quite the same as each other or the same as what’s gone before.

Ashleigh Fraser, Scottish National Junior Women's Road Race Champion 2014, reveals the winning diet

Ashleigh Fraser, Scottish National Junior Women’s Road Race Champion 2014, reveals the winning diet

Among the line-up in Edinburgh at 5.30pm on Sunday 12th April will be Scottish national junior women’s road race champion Ashleigh Fraser.

She’s going to explain the science of nutrition – what to eat to be an elite cyclist. It’ll tell me where I went wrong because I suspect my teenage diet of apple pies and Cheesey Wotsits weren’t much good.

And Professor Andrea Sella will be going further than Ernesto Colnago ever dared. If Eddie Merckx had come to a Cycling Science presentation before his 1972 attempt on the world hour record, he would’ve done even better. Andrea’s demonstration is a real eye-opener and UCI rule-makers should start taking notice so they can close another loophole…

I’m refining the aerodynamics demonstrations and showing some mildly embarrassing home movie from last century, together with some futuristic stuff. A tenuous link between Edinburgh Castle and the science of cycling will also be fully exploited without apology or shame.

The gigs for Chester are going to be full on and part of the University’s excellent efforts to boost cycling in the city. I used to live nearby and spend my weekends there so it’s great to be going back

Cycling Poster Chester Uni 2015 v2The first day, Friday 24th April, will be for students from year 7 to university level. I’ll be giving a cycling science presentation, with a few demonstrations thrown in, and then leading two short cycling science rides around the Thornton campus.

On the second day, Saturday 25th April, the University and others will be running several events in the city centre. I’ll lead a FREE public ride about cycling and science from the university’s city campus in the afternoon. Come along and take part in the experiments and demonstrations to learn about WHY cycling actually works.

In the evening I’ll be giving a presentation about what was probably the first mountain Autosave-File vom d-lab2/3 der AgfaPhoto GmbHbike crossing of the Greater Himalaya. I can’t believe I actually did it so do come along and learn about the ridiculous risks I took as a fool-hardy and unprepared younger self.

The Chester events are FREE. Book your tickets for the Saturday afternoon ride here. For the Himalayan adventure presentation, book your free tickets here.
