This probably sounds suicidal, but, in the case of you about to hit a solid object, like the side, front, of a car or the back of a truck what is the best way to minimize damage to yourself, or more importantly the bike?

Was riding home today and hit the back of a truck that was double parked after a cab cut off my go around route. Needless to say, before I hit the truck, I turned the wheel left and my fork was slightly scraped, and 3 spokes were hit, 2 of which now have a noticeable dent in them and the wheel is out of true; it scrapes my brake pads. I hope I don't need a new wheel... I don't think the rim is bent, but will go to LBS tomorrow to have them look at it. Should I be wary if they try to sell me a new wheel?

As I practice my crashes, is it better to hit head on with the tire absorbing the strike (I assume this will more likely cause the rim to bend, a more costly problem than bent spokes) or turn the wheel and risk having the spokes and fork get hit? But then I don't know if forks are susceptible to easy breaking... what do you think?

throw it into a no handed skid n put your hands out. catch yourself before the bike hits. ride away (actually had a friend do this)

it seems like you did the right thing, it definatly minimized the damage to your wheel. it would seem as if you would want to get the most surface area of your body on the object being hit and not be to clingy to your bike

never ever worry about the bike when an accident is about to happen. best advice i know is to look for a good place to fall (you have .25 seconds to decide) and then tuck yourself up and try to roll when you hit the ground. it's important not to spread your arms out, otherwise you break your collar bone.

I thought it was closer to .24 seconds.

Better have the LBS check out your fork and frame, while they're at it...

Make sure your frames not bent; look for bulges on the top tube and down tube near the head tube junction. Better yet, have your LBS look at it.

Worst advice ever re: falling. "Putting your hands out" will result in a broken limb, or worse.

Whenever you fall, you want to pull your limbs closer to your body, and tuck, to initiate a roll.

But the best way to crash is to anticipate dangerous situations, and avoid it altogether.

If it's totally unavoidable, you want to relax, and practice rolling/falling off the bike (on your carpet at home). Just as in the martial arts.

Sage advice. Don't be like me. Elbow surgery sucks ass. I won' be back on a bike untl mid-feb at the earliest.
I know better, I slipped stepping off of my bike at a stop and ****ered my arm real good. If I was moving I probably would have been fine.

To me, this is science. In my experience, once you realize you're in a crash situation, accept the inevitability of the crash. Assume it WILL happen and try and react in a way that puts you in the best situation AFTER the crash, ie beside the bus as opposed to under it.

if you are going down on a hill, try to position yourself so your feet are pointed down the hill, not your head. if you are getting caught by a car turning right and not seeing they are pinching you, i find it best to lock into a hard skid and keep stay as parallel to the car as you can. unclip the foot you think will need to pull out of if you go down.

Bam. Nailed it. I stopped Jujitsu (Like 3 years ago) and I still roll instinctively. It's saved me from concussions more than a few times.

Depending on which direction your going in, one of your arms raises up and bends at the elbow, rolling yourself onto your shoulder and protecting your head.

If you want to practice, take your hands and lay your fingers on top of eachother (Both hands facing down), making a wheel with your arms. Bend down to one side and put your hands on the ground and slowly try to roll over it.

As you get better at it, that circle becomes smaller and eventually it's just one arm that sort of wraps around your head.

If you just know you're going to t-bone a car and absolutely can't avoid it, its much better to go over the hood and land on the other side than it is to hit the cabin part of the car and get stopped cold. It's all about getting your kinetic energy dissipated over the longest time period as possibe. The faster your body comes to stop, the more you will hurt.

And if your laying the bike down sideways don't put your hand down!. This will be your first (and very strong) instinct, but don't do it! I learnt the hard way and had to have a cast on my arm for 8 weeks and the joint still hurts.

Well, here's what happened to my trek when I plowed into the rear quarter of a honda civic. Not the best photo, but you can see what happens when it's head on; the head tube bent on the frame... the stem lost it's grip, and two of the frame's main tubes buckled. There was more damage to the frame than to the rim at that speed.

I was in my top gear hauling ass (near 25 mph?) when some lady turned left (unsignaled) in front of me in broad daylight. I had a second or two of brake time, but just before impact I decided to go limp. I firmly believe this is what saved my ass. I aimed (as best I could) for the rear of the vehicle, rolled over the trunk after an impact between 15-20 mph. In my unqualified opinion rolling it out, limbs in, also was a positive factor.

I left a nice bike rack in her rear fender.

I also agree about the damage to the bike being the last concern. I remember saying to myself "stay loose, no hospital" right before impact, not "swerve fast avoid truing".

For real, your body should be your main concern when you crash. Crashing on a fg always sucks more for in my opinion cuz there is no freewheel so you kind of just have to go with the bike. Protect you dome and junk at any cost.

The one time I flew off and rolled, I did so into a busy intersection. Now I try to hold on to the bike for an anchor. Second choce Is arms out. I'd rather snap a collarbone than roll safely into oncoming traffic.
Though ,before imact, I try to make it a glancing blow, preferably unclipped, to minimize the imact.

i meant put your hands out against the object your gunna hit. if your going down its tuck and roll time. im really good at falling. i'v had my right shoulder slide on the white line of the bike lane for what felt like 2 feet before i stopped. it was drunken highsiding though. really though. its hard to roll with a bike between your legs. dont stiff arm the ground. just push away from the bike n roll away. dont be afraid to lose some skin though.

Not blaming crash victims here or anything, but if you crash a lot (more than maybe once or twice say ever, but this will vary I guess), you might want to consider how you're riding your bike. In ten years of daily commuting, recreational riding and training in an urban center where, just like everyone else here, the drivers are worse than anywhere else (though visitors to Montreal are regularly shocked at how careless and aggressive the drivers and infrastructure are here), I've been involved in 2 crashes involving other vehicles, both in cases where I was passing a car on the left with plenty of space and completely visible, and the driver suddenly turned left.

Again, I'm not suggesting that it's always a bikers fault when there's a motor vehicle-involved crash, but it certainly can't never be. It certainly hasn't been in my experience :D

A second on not putting your hands out - I separated my shoulder last year when I went over the bars of my mountain bike going fast when I took my eyes off where I was going for a split second, and in the 3 hours that I was flying over the bars (wow did it ever seem slow) my instinct was to put my hands out in front of me. That wasn't the cause of it, but if I didn't land my shoulder directly on a sharp incline, I would have broken any combo of a hand, wrist, arm or collarbone.

I'm far less worried about crashing into cars than I am about the pedestrian situation...

I had the experience once of swerving my bike while simultaneously tackling a startled woman who had darted accross the street, thereby breaking her fall. She explained it to me after the fact, "I am okay - you hugged me"; this wasn't a .24 seconds conscious decision by any means.

Luckily, everybody was okay in the end. The woman was spooked and I got an adorable barely noticable scar on my right elbow. Still, I was waking up in a cold sweat from that nightmare where I level a pregnant jaywalker for weeks...

12-19-06, 09:18 PM
Pregnant jay walkers and poor stroller handling skills are two of my worst fears.

But yes. I've been told to tuck and roll many times, not only for biking. It seems like one of the best policies, along with relaxing. Not easy to do, but when in a strange circumstances, it is usually best to relax.

It's been said before, but can't be said enough, tuck those mother-clucking arms.

I done broke a collar bone and a wrist (separate incidents,) because my dumb behind tried to do the whole cat-landing thing. Turns out that cats trump lanky teenagers in the arena of grace.

In my crashing experience with clips (twice), my feet always get yanked free of the pedal without incident. No problems at all. I keep them on the looser side though.

worst thing to ever happen to me was a fishtail that got out of hand during a skid comp. i did the tuck and roll thing with the bike still on my feet, would have been sweet if i could have gotten back on the wheels and continued the skid... like a sweet barrel roll as part of the skid.

Riding with fridgerobot one day... i was way behind so i sprinted to catch up. I look up, and im closing in on him, then i realize that our destination is about two feet in front of me, he is already stopping. A whole lot quicker than i was ready for. I skidded, managed to turn a little bit, not enough. Slam into said robot. Miraculously unclipped from my Cannondale SPDs, slam into fridge *he catches my bike*, i fly over the handle bars and under a car who was trying to exit where we were entering. Hit my head on the back wheel, slammed under her rear bumper, bending it. Reverted to my rugby days and curled up int a little ball grabbing my head. Meanwhile fridge is trying to coax me out from under the car while i am still in the ball saying, " nah man im good, just leave me, I'm ok." Get up dust myself off and we carry on the day as if nothing happened. Luckily the driver didnt see the massive dent i produced on her 1980s camry POS edition.
good times.

I'm pretty sure I was born with "tuck and roll" programmed into my brain. When I was 5 I un-buckled myself, opened a car door and fell out on a freeway off ramp. My mom says she remebers looking out the back window and seeing me balled up, bouncing and rolling down the road like a basketball. I jumped up and ran after the car, I remember bieng afraid they were going to leave me. I've been in a number of pretty bad BMX and MTB wrecks, a motorcycle wreck and fell off a 15 foot cliff. Tuck and roll saved my ass every time. I've had tons of lacerations, bumps, bruises and even been knocked out a couple of times (I should practice the arm over the head thing), but I've never had a broken bone.

Depends on your priorities.

If you want to protect your bike at all costs: at the point of impact, jump. This will turn your bike into a catapult, all of the kinetic energy you have will go into pitching you forward. Your bike will have minimal kinetic energy to dissipate. You will most likely be tossed far and hard.

If you want to protect your body at all costs: do what everybody else says, tuck and roll you sissy.

My toe clips really messed me up when I crashed last year. A ped walked right in front of me as I was riding down the bridge, I clipped his shoulder with mine and went flying over the bars. I was still clipped in and landed with the bike on top of me and my knees all bent up and bruised. One of them still hurts from time to time thanks to that incident.

i think i am too. at least to some extent. as a kid we used to do lots of stupid stuff on our bikes, and as a result crashed a lot. if you didn't know how to crash, you'd be screwed. i've never broken a bone in my body either.

I've eaten **** twice, and both times I wasn't able to clip out... I'm not sure how I feel about that. Both times I ended up on my back with my bike on top, and both times my bike made it out safe with handlebars tweaked a bit. I think I'm pretty lucky.

queerpunk
12-20-06, 09:51 AM
i'd ad a bit more - afterthisnap mentioned this. try to make it a glancing blow. try real hard not to hit something dead on (T = bad), so turn parallel to whatever you're about to hit, if you can. hitting the ground, it seems to me, is gonna be preferable to hitting a solid object at 20mph and coming to a dead stop.

kemmer
12-20-06, 12:02 PM
True, if you're going to hit a car aim for the trunk or hood so you can (hopefully) fly or roll over the car instead of hitting it.

Edit: you might want to avoid the front of the car if it's still moving. You don't want to be on the business end of a moving vehicle if you can avoid it.

For sure. Clipless will release before it starts twisting your ankle. It may stay clipped in during a crash, but I think it'll only do that if you manage to fall while keeping your foot aligned with the pedal. Toe clips... it's a tossup.
(Actually, I'v had a couple of "crashes" with clipless when I lost it a slow speed and managed to bail out, lay down the bike and stay on my feet. Some of these cases involved stepping over the handlebars... I still don't know how I did that. That's definitely not doable with toe clips cinched tight.)

I just don't crash that much (knock on wood) - I've had a couple of decent wipeouts, both during scavenger hunts, and I can't think at all, let alone do some fancy maneuvers. Maybe I need to crash more to learn how to fall, it's just not something I'm good at.
