Is it necessary to wear a bike helmet when commuting to work?




Tks O


In addition, I only ever ride my bicycle on the pavement/side walk shared by pedestrians; the only time I go on the road is when cross the lights for pedestrians.

Is it really necessary for commuters to wear a bike helmet. I just find it unnecessary to wear helmets on the street because the chances of collision and injury are a lot less than on the road, and I question the compulsory bike helmet laws.

If wearing helmets is mandatory, why don't we make the inclusion of airbags mandatory for all cars as well then?



Answer
Even when I ride on the sidewalk, which is illegal where I live, I have close calls when people are backing out of driveways and such. Not to mention the people that are getting out of their house I almost hit.

http://bicyclesafe.com/
"The Crosswalk Slam

You're riding on the sidewalk and cross the street at a crosswalk, and a car makes a right turn, right into you. Cars aren't expecting bikes in the crosswalk, so you have to be very careful to avoid this one. This collision is so common we've lost track of the number of people who've told us they were hit this way, such as Ray John Ray. One study showed that sidewalk-riding was twice as dangerous as road riding, and another study said it's even more dangerous than that.

How to avoid this collision:

1. Get a headlight. If you're riding at night, you should absolutely use a front headlight. It's required by law, anyway.

2. Slow down. Slow down enough that you're able to completely stop if necessary.

3. Don't ride on the sidewalk in the first place. Crossing between sidewalks can be a fairly dangerous maneuver. If you do it on the left-hand side of the street, you risk getting slammed as per the diagram. If you do it on the right-hand side of the street, you risk getting slammed by a car behind you that's turning right. You also risk getting hit by cars pulling out of parking lots or driveways. These kinds of accidents are hard to avoid, which is a compelling reason to not ride on the sidewalk in the first place.

And another reason not to ride on the sidewalk is that you're threatening to pedestrians. Your bike is as threatening to a pedestrian as a car is threatening to you. Finally, riding on the sidewalk is illegal in some places. (In Austin, those places are the Drag, and downtown on 6th St. and on Congress). If you do plan on riding on sidewalks, do it slowly and EXTRA carefully, ESPECIALLY when crossing the street between two sidewalks."

"1. Don't ride on the sidewalk. When you come off the sidewalk to cross the street you're invisible to motorists. You're just begging to be hit if you do this. Keith Vick was killed this way in Austin, TX in Dec. 2002."
~~~~~
"Contrary to popular belief, you increase your chances of getting hit by car when riding your bike on the sidewalk. I know you may find it hard to believe but its true.

While riding in the street is more intimidating, it places you in a position that makes you more visible to the motorist. Usually people will ride on the sidewalk because they want to stay away from cars or they ride against traffic in the street because they are afraid of being hit from behind: they "want to see the cars coming at me". Crashes on sidewalks comprise close to fifty percent of all crash types. They are more common because every driveway forms an intersection and, if you went to driving school you may remember, that most crashes happen at intersections. In traffic engineering jargon where two vehicles cross paths is referred to as a conflict point and traffic engineers work very hard at reducing or eliminating conflict points.

Essentially every driveway that crosses the sidewalk forms a conflict point. Couple this with motorists not stopping at the sidewalk before entering the street and looking at traffic in the street not for bicyclists on the sidewalk and you have recipe for a crash. By cycling in the street you completely avoid these conflict points. The motorist stops before entering the street and is looking where you will be before they cross your path. While these crashes are usually not fatal, they can easily result in an incapacitating injury especially if you are not wearing a helmet. In my expert witness practice, the majority of sidewalk related crashes I've been involved with the rider was not wearing a helmet and usually result in brain injury"- http://ezinearticles.com/?Bicycle-Safety---The-Problems-With-Sidewalk-Riding-and-Against-the-Flow-of-Traffic&id=1857311

The distance I travel from my house to my work place is relatively low. It's too far to walk, but driving is unnecessary and I think I can save petrol if I cycle instead. Because of the short distance, I think the chances of collision and injury are extremely low.
@ Stef: I would not advise you to show that link again. The material is not suitable for children, and quite frankly, I think you would agree the overtly sexual ads on that page are best not seen.



Answer
It really comes down to your own decission wether you think you will be able to survive the unknown that maybe lurking around the corner , such as an out of control garbage truck that has jumped the footpath and is heading straight for you, with a helmet your chances for head injury are greatly reduced. For example i have a motorcycle licence but i would never ride in the traffic as i have seen too many of them that have been killed, and they got on their bikes just before their accidents thinking it won't happen to me! . what will change you mind about helmets is to take a look on some of those shock web sites and see what people look like after not wearing a helmet , i have listed one below WARNING EXTREEMLY GRAPHIC.

mountain bike for commuting?




Derek


i've decided to use this old mongoose mountain bike that has been sitting in a shed for years to commute from home to work or near by stores. do they make for good commuter bikes? my home town (Tucson) is known for being a bike rider hotspot, but i hear about people on bikes being struck by vehicles often. i figured if i use the mountain bike i could ride on the dirt aside the roads instead of the tiny bike lanes on them. thoughts? opinions? thanks!


Answer
You may not like this answer... I use a mountain bike occasionally for "Urban Assault" riding. And it's a damn good one - the same kind the police use.
http://archive.fujibikes.com/archivebikes.php?prodid=2003&prodname=Police%20Patrol&modelyear=2012
It has lock out front forks & city tires. If that Mongoose has suspension forks & they can't be "locked out" - bad choice for a "commuter bike". But...at least install some Kenda Kross tires on it.

The key to commuting in the city is being SEEN! Designated bike lanes are a joke. Separate but equal my @ss! Bike lanes put you to the far right - out of the "line of sight" of most tunnel vision motorists. Whenever there's a designated bike lane - I hug the LEFT part of it & go out into the traffic lane if need be. Most of these bike lanes also put you right smack dab in the "door zone" should some fool not look first before opening a car door.

What's a good bike for commuting?

Q. I need to learn how to ride a bike, I'm 21 and don't know how. I'd like to use this bike instead of a car (not that I have one). But in the future I wouldn't mind learning how to ride competively.. I'd really like a bike that would be good for health and travelling, then.. I'm a student so I don't want anything too expensive, maybe £200 tops? Must be available in the UK - do you think I'd be better off going to a bike shop or ordering online?


Answer
Hey Rainbow,
Hate to be one of those that echos what you probably do not want to hear but yeah... An inexpensive bike put to use as a regular commuter will have you wishing you'd spent more in the first place.

While I'm not totally against online retailers there are a number of things you have to take into account like what bike is best going to suit your needs? What size frame is best for you? And the real kicker... Who's going to assemble the darn thing? A bike that's been improperly assembled can be a real nightmare to sort out and downright dangerous to ride. Most shops charge dearly for this service and with good reason.

There really is a lot you have to know and specific tools that you have to have to get a bike from out of the box to going safely down the road. Most online retailers make the assumption you already have the skills and tools so any directions that may come with the bike are generic at best and in most instances? Boxed bikes do not come with instructions.

If you have a mate that tells you he's willing to assemble a bike for you? Don't let his grubby paws anywhere near the thing unless he works on bicycles FOR A LIVING! and has ALL the necessary tools to do the job properly!

Used bikes can be a real can of worms as well... While you may find a gem of a bike for little money, you really have to know what you're looking at to be sure and that takes experience.

So my advice is this... Save up some more, Go to a few local bike shops, that's a brick and mortar establishment that sells ONLY bicycles, take a look around and ask some questions. Find out what they charge to assemble a bike,what they charge to check out a used bike, what they have to suggest for a commuter from their stock and see how the pricing stacks up. I think you'll find it's pretty much the same as for what you see online plus assembly. Check out a few shops and pick the one that treats you best. And keep enough in the budget for a good lock, lights and a HELMET and wear the bloody thing EVERY time you ride!

Why are there fewer commuter-cyclists lately? What are the main thresholds to bike-commuting?

best bike helmet commuter on Image for POC Receptor Commuter Bike Helmet

LastGenera


Imho, the bike manufacturers are to blame, and here are my opinions. What's your two cents?

In my view, bike saddles are uncomfortable and possibly cause the dreaded Male Dysfunction Syndrome. Also, the Shimano fancy gears and shifters wear out in only 1,000 miles and are costly. In comparison, old bikes had gears/chains that lasted 20 years or more.

Open-face bike helmets don't protect the teeth from impact, and there imho aren't inexpensive full-face helmets for people who wear glasses, size 63cm, or XXL.

Then, there's bike theft.

Any other reasons not listed here?



Answer
I hate to say it, but I strongly disagree on every point you've listed.

The 'root' of the low visibility of commuter biking is that the population (as a whole) has been encouraged to obtain and then maintain a sedentary lifestyle. Suburbanization and the 'sprawl' left over from the 50's contributes to longer commutes in terms of distance and time. Working longer hours at a given job means less time to make the travel between home and work .. which results in looking for a faster means of doing so.

The average level of activity in today's population is around 50 percent of the activity level of the 1950's population. That means folks are simply doing less in the way of exercise, and when they do attempt it, it is less strenuous. Sure, there's a handful of exceptions who take exercise (and strenuous types at that!) as a way of life ... but they are more than compensated for by those who do absolutely nothing.

I've ridden on the same Shimano drivetrain on each bike I own (the newest one is a 2004, the oldest is a 1969, and there are three from different ages in between). No bike has less than 7500 miles on it ... the 2004 road bike has almost 8000 miles in just over 2.5 years of riding. There's nothing wrong with the shifters, brakes, rings, cassettes, chain, or freewheel on any of the bikes.

The variety of saddle materials and shapes out there means there's something for everyone. The more probable cause of an uncomfortable saddle experience is that you aren't fitted properly to the bike itself! Check your overall fit at a local bike shop ... there's a fair bit of geomtery involved. And no two people are exactly the same, so your setup has to be somewhat 'custom'.

Cleanup after arriving at work from a lengthy commute can be tricky, if your place of employment doesn't have showers. However, it's pretty much guaranteed it DOES have a washroom - which means running water. Pack a cloth and a towel, some work clothes, and some soap/deodorant. You can clean up with relatively little fuss quite quickly.

As to theft - there's a couple of answers to this. One is to use a 'beater' bike for the commute, so it doesn't appear as attractive to potential thieves. The other is to subtly pressure your employer into providing safe storage during the workday. Email me - I can give you a good example of how I changed the way things were done with my previous employer. Or check a previous answer I've given here on Yahoo! Cycling ... it pretty much portrays the same example.

As to actually pressuring the employer ... use the idea that a fit and active employee is a better health risk from an insurance point of view, so it would be to his benefit to set up safe storage in lieu of higher premiums.

Lastly - there are several styles of bicycle out there on the market. The 'commuter' bike is designed specifically for getting around an urban area; it's slightly more comfortable riding position than a true road bike, and easier to pedal and manoeuvre than a mountain bike. They can be found fairly cheaply; take a look at your local shop. Then try a couple of styles out ... there's one out there for everyone. If you can't find a good bike for you out there, it isn't usually the manufacturers fault - it's yours, for not doing the legwork (and yes, sometimes that means exercise as well!).

What amount of cc is good for a starter bike?




Ben Stoepp


I'm about to buy my first motorcycle. I have ridden a moped before but never motorcycle. I want something with a good amount of power but nothing that will knock me off the bike. So what area of cc should I be looking in?


Answer
It seems to me that all your answers (above) are pushing you towards sport-bikes (Ninja, CBR, GSX, etc)... have you considered a cruiser?

Cruisers have a low center of gravity, well balanced, and very easy to learn on for a beginner. The 650-750 Honda Shadow line, V-star from Yamaha, Boulevards (S50/S65) from Suzuki, or Vulcan's from Kawasaki are all pretty much the same look, feel, and ride... All of them are capable around-town, rural-roads, on the Interstate, or cross-country (yes, I've taken a Shadow from coast to coast).

If you want a sport-style bike... I recommend starting small with 250cc to 500cc. But if you're looking at cruisers, starting out at 650-750cc is not out of the question. There are also choices of Sport-Touring bikes in the 500-700cc range, which look sporty, yet maintain the riding position of a cruiser, lightweight, good fuel economy, and VERY comfortable on long rides!

If you're worried about too much power... I'll give you some info/stats on some of the bikes I have...
CBR250... not enough to make you think you're going to fly off, but very capable of highway speeds and faster off the line than any average car. This bike is awesome on the rural roads and around town.
CB750-NightHawk... 0-60 in 2.4-sec... yes, it has the power to scare you to death, so not a good starter bike!
Shadow 750... Great starter bike, good power, capable of cruising 80mph all day long, and not quite "push you off the seat" power. Low center of gravity, and excellent "around-town" or commuter bike.
Sabre 1100... Just like the Shadow, but a little heavier and more "oomph". It is better suited for longer highway trips and 2-up riding, but capable as a commuter. Could be a beginner's bike, but only if you can handle the additional weight and torque.
Goldwing 1800... yeah, we won't go there... it's a rolling couch, weighs as much as a sub-compact car, and this beast is MADE for touring! NOT a beginner's bike!
VT700C Shadow ('85 model)... Yes, its a cruiser, but 0-60 in 3.5-sec. YES, it will launch you into the pillion and make you hang on if you hit it hard! This is also NOT a good beginner bike unless you have some experience!

Take the MSF course... PLEASE! Learn to ride properly, wear the gear (helmet, gloves, jacket, boots, etc), and be safe... remember, all other drivers are trying to kill you... remember that every time you sit on the saddle and you'll be a bit safer every time you ride!

Should i get a full faced helm and how often should i refill?

best bike helmet commuter image



Matrix


i have a nighthawk 250, and wondering if i should get a full faced helmet, because i would feel kinda goofy since it is not a sportsbike. however i have problems where i use my regular half helmet and a pair of sunglasses, i get air in my eyes and i feel funky when i go over 45 mph
also i used to have a ninja and i would refill every 200 miles or so using the odometer, so how often should i refill on this?



Answer
I have a Honda Shadow ACE 750 and a full face helmet. I admit I thought it would feel odd, but I don't mind it and I've noticed a lot of bikers here in Vegas wear full-face regardless of the kind of bike they're on.

As far as refilling goes, the snide answer is "before you run out of gas". But there's truth there. Figure out how much you get, roughly, per gallon and how much the tank holds and try to plan it out accordingly. Of course, if you're using the bike as a commuter, just fill it up once a week regardless and you're golden.

What do you wear for cycling in cold/wet weather?




Rokia K


I'm a bit concerned because I've never really biked in cold weather before, and on the one occasion when I got caught out in the rain in otherwise reasonably warm weather, I was really uncomfortable. With my jacket closed, I was overheating, but with it open I was cold and wet. Can anyone help me figure out what to wear this winter (in Atlanta, not Alaska) for cycling?

Thanks!



Answer
Riding in the wet when temperatures are close to freezing is unpleasant, your extremities will get wet and very cold, but if temperatures are above, say 45 f, you can stay pretty comfortable if you have the right gear and if your bike is equipped for wet weather. My commuter bikes were always equipped with mudguards to keep splashing to a minimum, but even then, my feet always got wet no matter what waterproof footwear I had. Staying warm is more important than staying dry. For colder weather, I have a variety of clothing solutions, tights, leg warmers, knee warmers, arm warmers, vests and jackets. Wicking undershirts, long sleeve jerseys and of course shoe covers. You also may need some kind of thin hat or balaclava to wear under your helmet. If it gets cold, you can also use clear packing tape to cover some of the vents on your helmet. With practice, you can learn to choose the right mix of clothes for the day, a difference of less than 5 degrees can mean 1 more layer, or 1 more item of cold weather gear. Acclimatization also plays a big part, you get used to being out in cooler temperatures. My ride today started out at about 42 f, I wasn't even wearing a jacket, just a windproof vest, long sleeve jersey, short sleeve undershirt, and a short sleeve jersey. I had included arm warmers, but quickly had to take them off because I was too warm, but a month ago I would have been cold, my body has adapted. You have to experiment to find out what works for you. I have been on rides when my water bottle froze without much discomfort.
