There is a fundamental truth in cycling, and it is this:
听
When riding on a trail, it鈥s virtually impossible to pass a walker, runner, or hiker from behind without scaring the living shit out of them.
听
This puts us in something of a bind. After all, the cyclist-pedestrian relationship is a fragile one, and in some communities our trail access hangs in the balance. However, what are we supposed to do when our very presence is all it takes to frighten people out of their shoes?
听
No doubt this has been an issue since the very first velocipedist called out, 听鈥淎hoy!鈥 And over the years our fair warning cry has evolved thusly:
鈥On your left!鈥
It鈥檚 one of the most common utterances in cycling, but to me it's also one of the most cringe-enducing phrases in the entire English language, right up there with 鈥淲elcome to TGI Friday鈥檚!鈥 and 鈥淥K, I鈥檓 going to check your prostate now.鈥
听
Of course, giving people a heads-up when you鈥檙e about to overtake them is often a good idea, and in this regard 鈥淥n your left!鈥 has certain things going for it. It鈥檚 concise, it conveys your position relative to the passee, and it consists of three monosyllables for weight savings and enhanced stiffness.
听
The problem, however, is in the delivery. Too many bike-path cyclists handle it as awkwardly as they do their carbon time-trial bikes. 鈥淥n your left!” they bellow imperiously, their hips rocking on their maladjusted saddles as they push a way-too-large gear into the distance.
听
In this sense, 鈥淥n your left!” is like a Godfather impression. Sure, some people can pull it off, but the vast majority sound like idiots. For this reason alone, it deserves to die.
听
Of course, the fact remains that you鈥檙e almost certainly going to scare (or at least annoy) people regardless of how politely you warn them of your approach. I know this because I鈥檝e been conducting pedestrian passing experiments for years. Moreover, I鈥檝e been doing so in and around New York City, which as the most densely populated metropolitan area in the United States makes it the CERN lab of passing studies. Here are some warning techniques I鈥檝e applied, with varying degrees of success:
Polite Discourse
If you鈥檙e riding somewhere so crowded that you鈥檝e got to warn other trail users and all you鈥檝e got time for is 鈥淥n your left!”, then you鈥檙e riding too fast. Slow down and use your grown-up words. The rules of polite discourse don鈥檛 change just because you're riding a bike, and if you wouldn鈥檛 say it in a supermarket aisle or on an escalator then you probably shouldn't say it at all.
Bell Ringing
In theory, the delightful chime of a bell would evoke a Buddhist monastery and elevate both you and your fellow trail users to a state of mindfulness. In practice, it can be jangly and irritating, plus there鈥檚 just something about ringing a bike bell that can make you feel like an idiot.
听
This is not to say the bell has no place on a bicycle. After all, if you want to communicate your imminent approach from a distance, it鈥檚 a whole lot better than shouting. Plus, there are all sorts of fancy bike bells now that are just as at home on your race bike as they are on your townie, so it鈥檚 not like you鈥檝e got to ride around with a great big saucepan on your handlebars.
听
Still, depending on the circumstances, your bell might only be slightly less likely to startle someone than an 鈥淥n your left!鈥 and the only time it gets a uniformly positive response is when you use it to greet large groups of schoolchildren.
Using Your Bike
To some extent, warning people that you're going to pass is less about not startling them and more about choosing when to startle them. Do you want to scare them shitless with the bell from 50 feet away or do you want to do it at point blank range when you finally enter their peripheral vision? (Generally you want the former so they don't veer directly into into your path, but in a way it鈥檚 all like waking a sleepwalker anyway, so what鈥檚 the difference?)
听
However, if (and this is a big 鈥渋f鈥) the person you're passing is not wearing headphones, you may be able to gradually enter their consciousness without frightening them by using the mechanical properties of your bicycle. For example, certain boutique hubs emit a loud ratcheting sound while coasting, and that may be enough to gradually get someone's attention without startling or angering them鈥攁ssuming they're not suffering from PTSD after a killer bee attack. Gratuitous shifting might also offer enough of a subtle warning, though if you鈥檙e running an electronic transmission the whirring of the servos might make them think they鈥檙e being stalked by some sort of killer robot.
听
Or, if all else fails, you can pop your rear wheel up and down and hope for some chainslap.
Using the Environment
If it鈥檚 an unpaved trail, you may be able to ride over some twigs or rustle through the underbrush. The best-case scenario is they stop and stand stock-still like a deer. The worst-case scenario is they go scampering into the forest like a deer.
Waiting Silently for an Opportune Moment to Strike
If the walker, hiker, or runner is hearing-impaired due to the application of some form of in-ear speaker, then you may have no choice but to follow behind until there鈥檚 room to pass and then pounce. The danger here is that the person you鈥檙e passing will almost certainly bolt, so make sure you wait until there鈥檚 plenty of room to minimize the risk of collision. Also, in these situations, you can be sure the person will tell you off for not warning them鈥攁nd loudly, because they鈥檝e got to shout over the music.
In the End You Can't Win, So It's All About Your Attitude
Sure, the indignant suburban power-walker or the headphone-addled runner may be annoying, but do you really want to live in a world where people can't relax and zone out once in awhile? As long as they鈥檙e not operating heavy machinery, what鈥檚 the big deal? And in the absence of motor vehicles, it鈥檚 you who's operating the heavy machinery, so act accordingly.
听
And save the 鈥淥n your left!鈥 for warning people about impending animal attacks.
