There's a saying. Well, actually, there's quite a lot of sayings. But yes, there's one saying in particular that we'd like to draw your attention to: "If it ain't broke, don't fix it."
When it comes to bicycles, and the willingness of so many cyclists to modify their rides, it appears that this saying doesn't really apply. Now, of course, plenty of bike modifications serve a real and useful purpose; whether that's making the suspension better, making the seat more comfortable, or something else entirely.
However, many bike modifications are absolutely insane. Some of these, if we're being fair, are insane in the good way; in a way that makes you exclaim "WHY HAS NOBODY ON EARTH THOUGHT OF THIS BEFORE?!"
But then, on the other hand, some of them are insane in the way the evil villain from the Saw movies is considered to be insane so I guess it's swings and roundabouts on that front.
Anyway, for your viewing pleasure, here's 15 insane bike modifications. We'll let you decide which of them are good, and which of them are crap.
1) Push Bike BMX With Flamethrower
We're not entirely sure what purpose this flamethrower modification really serves but if a full-scale action sports war every breaks out, we want this gnarly two-wheeler on our side. Expect James Bond to be riding about on a similar bicycle in the next 007 outing.
"Eat my fire, Blofeld. Eat. My. Fire."
2) Crazy LED BMX/Parkour
Look, we know we've shown you loads of LED bike stuff before but this video is too good not to share with you again. Go on. Give it a watch. It will light up your life like a bunch of BMX LEDS light up a darkened underpass. Great mod, great skills; great!
3) Snow Biking
Skiing?! On bikes?! You must be mad, Mpora! Literally insane. And, yes, while we have been known to write some pretty strange content in the past...this time we're being serious...deadly serious.
This video demonstrates how modified ski-bikes perfectly combine the fun of skiing, with the sheer rush of downhill biking. This video, or the audio at least, also drew attention to how dreadful music can make us want to pierce our own eardrums with a rusty fork.
Thankfully, on that note, the rusty fork was wrestled from our grip before any serious damage could be done. Cool modification. Terrible song.
4) Self-Balancing Unicycle Modification
We've included this video not only because we sort of quite enjoy the "geek chic" of the self-balancing unicycle mod, but also because the presence of the man in the corner of the screen made us laugh.
Clearly, it doesn't take much to make us laugh.
5) Underwater Bicycles
This video by no means a thrill-a-minute rollercoaster of emotion, but there is something genuinely quite satisfying about watching bicycles getting used on the bottom of a swimming pool.
If you ask us, the Tour de France would be a far more entertaining viewing experience if they threw in a couple of underwater sections.
6) Smoothie Bike
You know what it's like. You've just hit a 40km bike ride out of the park, and fancy a well-earned sit down. You're sitting there relaxing, when you find yourself overcome with the urge to slurp on a refreshing smoothie.
But, guess what? Nobody is going to make the refreshing smoothie for you so you've got to somehow drag yourself to the kitchen, and put in some more hard work (you've already done 40km, for crying out loud).
Now, imagine a world where the very process of riding a bike creates the delicious smoothie for you. That world would be amazing, right? You'd want to live in that world, wouldn't you? Newsflash: you already do.
It's never been easier to kill two birds, the bike one and the smoothie one, with one stone. Ride your bike, get off you bike, pick up your smoothie, and have yourself a well-earned sit down. Absolute magic.
7) Amphibious Bike
With this genuinely awesome modification, you'll never again have to swap your bike-riding for a ferry (unless you're going to Calais from Dover, in which case...we recommend still using the ferry).
8) Giant Guitar Bike
Some people love guitars almost as much as they love riding bikes. These people, god bless 'em, find themselves knee-deep in a dilemma. Do they spend their disposable income on a new bike, or a new guitar? Oooooh. Decisions, decisions, decisions.
This guy clearly couldn't decide so came up with a giant-guitar-shaped solution that, depending on your point of view, is either brilliant or shit.
9) Flying Electric Bicycle
"I believe I can fly...I believe I can touch the sky...while riding my bicycle," sang R Kelly on the Space Jam soundtrack.
Now, before seeing this video of a flying-bike modification in action we thought R Kelly was just being figurative rather than literal with his lyrics.
What do we think after seeing the video? We're not entirely sure. Bikes that can fly? *shrugs shoulders* Welcome to the future.
10) Treadmill Bicycle
Nobody said these bike modifications were going to make you look cool. Nobody. That being said, if you're looking to spice up your weekend hikes...you could do a lot worse than these treadmill bicycles.
11) Sofa Bike
With your super-busy outdoor lifestyle, you might not have realised just how many lazy people actually exist. But yes, the world is filled with lazy people; lazy people who would rather eat carpet than go for a lengthy bike ride. For these people, the sofa bike might just be the perfect solution.
12) See-Saw Tandem Bike
Completely pointless and yet, we really, really, really, really, really, really, really, really, really, really, really, really want to have a go on one (after swigging eighteen pints of beer).
13) Back-To-Back Tandem
This is officially Dizzee Rascal's favourite bike.
Why? Because it's...BONKERS!
14) The Forkless Cruiser Bike
Where the fork are the forkin' forks on this forkless bike?!
15) The Shoes-For-Wheels Bike
We wheel-y like this modification. It's stupid, and arguably a complete waste of trainers, but there's just something about the insane quirkiness of this that makes our thumbs point towards the sky like fleshy-pylons.
If, however, this idea takes-off and becomes the mainstream we'll eat our old trainers with a side-order of used football socks.
