Mrs. Kelly


I want to get a bike seat for my baby so she can ride with me. What is the minimum age she can be to ride/wear a helmet? Anyone know?


Answer
Obviously a child can't be on a bike until they can safely wear a helmet.

http://www.helmets.org/little1s.htm
Nobody we have met in the injury prevention field recommends taking an infant of less than 12 months in a bicycle child seat, trailer, sidecar or any other carrier. Nobody. And we do not either.
New York state law prohibits it. The US Consumer Product Safety Commission thinks it is dangerous to take a child under one year on a bicycle, and here is their rationale:

Maurice Keenan, MD, from the American Academy of Pediatrics [21], requested that a minimum age of 1 year be reflected on the label for helmets intended for children under age 5. This would better convey the message that infants (children under age 1) should not be passengers on a bicycle under any circumstance.

The Commission agrees with the commenter that children under 1 year of age should not be on bicycles. Children are just learning to sit unsupported at about 9 months of age. Until this age, infants have not developed sufficient bone mass and muscle tone to enable them to sit unsupported with their backs straight. Pediatricians advise against having infants sitting in a slumped or curled position for prolonged periods. This position may even be exacerbated by the added weight of a bicycle helmet on the infantâs head. Because pediatricians recommend against having children under age 1 as passengers on bicycles, the Commission does not want the certification label to imply that children under age 1 can ride safely.

Source: 16 CFR Part 1203 Safety Standard for Bicycle Helmets; Final Rule, page 11726

That explains why you will not find a child helmet on the market sized for a tiny tot. You certainly do not want to ride with a bare-headed child, and in some places it is illegal. In fact, several states have laws against taking children under one year of age on a bicycle, even with a helmet.

Parents love their babies and love their bicycles, so it is natural to want to put the two together. That thought occurs to every bicycling parent, generally before the child is born. We see messages on the Internet indicating that some parents do put their children in baby seats of one design or another and take them along on trailers starting as young as five weeks. Others use a baby backpack. At slightly older ages, people use front or rear-mounted child seats. A few (mostly in the UK) use sidecars. Each has its advantages and disadvantages. A disclaimer: our purpose here is to cover the risks, so you know what you are getting into. We are hearing more these days about undiagnosed brain injuries, with symptoms too subtle for doctors to detect, but very real to families. And that comes to mind whenever someone asks us about babies and biking. We worry about your six-week-old entering the first grade six years from now with a small but detectable mental handicap. That is alarmist; this is an alarmist page.

Infants: Child Seats Vs. Trailers Vs. Backpacks Vs. Third-wheel Cycles

The primary determinant of when an infant can join his or her parents on bike rides is the strength of the the child's neck. Because of the jostling and the additional weight of a helmet (8-10 oz.), this is a few months after a baby can first hold their head up. Note: Some jurisdictions have laws requiring passengers on bicycles to be at least one year old.

Usually by age 12 months parents can start checking with the child's physician to see if they have the neck development to safely go for a bike ride. Most toddlers' neck and shoulder muscles can tolerate the weight of a helmet and absorb shock from bumps in the road at 1 years old.

We know of no comprehensive study on the best method to carry an infant on a bike and there are risks associated with all of them.. Here are some factors to consider:

what kind of bike do i get for casual riding?

I'm looking for a bicycle that's cheap. I might even get one on craigslist.
I just need it to get to campus and back, and between classes.

1. BMX, mountain, road, etc. Or does it not matter?
2. What size? i'm a 5'7 male. All the bikes online say 20' or something. Is that standard?
3. Any tips?

thanks

You buy a bike, just like a car, for the type of use it will get. You don;t but a jetta if you are gonna haul wall board and sacks of concrete. Nix on the BMX. Get a mountain bike if you are gonna ride on mountain trails and rough roads. Get a cruiser or single speed if your needs are short, slow, riding on perfectly flat terrain. If those are not your needs, get a road bike. If you intent is not to race, then get a hybrid bicycle.

At your height, a 52 cm ( 20 inch) road frame will be just fine. The bike will come with wheels that are either 26 or 27 inches on diameter. The hybrid bike will have upright sitting, road type gearing, wider smooth tires, and a light frame. It will provide you with a fast, safe, and smooth ride on streets, roads, paths, and even light trails made of pavement, dirt, grass, gravel, and even packed sand.

For your use, put a rear rack on the back, and attache a large stainless steel basket to it. You can throw in books, soccer bags, even a large bag of groceries with no muss or fuss. You can use this bike for daily commutes, cardio workouts, or even long distance weekends rides in flats or hilly terrain with no problems.

Get two water bottle cages, quick releases for wheels and saddle... helmet, padded cycling shorts (road or mountain) and a cycling jersey shirt. For your emergency use you should get a seat pack with spare tube, tire irons, patch kit, and a frame mounted mini pump.

For security, because of the campus thing, get two locks, a Krypto Ulock, and a Schlage 6 ft x 5/8 inch cable lock (available at Lowe's) to use for securing your bike while at class or the library. Carry the locks in a back pack. If a high loss campus, or if you will be away for a while, take your bike's saddle and front wheel with you. Store your bike vertically, on it's back wheel, in the corner of your apartment or dorm room.... lock it up there too!

Learn how to ride properly. Read up, or ask about 'spinning' on this forum. There is a proper way to ride a bike.... and that is by 'spinning'. It would be like playing tennis without having a back hand stroke, or playing football without knowing how to block or tackle!

questions about losing weight by riding a bike?

bicycle helmet size 8 on Helmet 192 Matt Bk/Yellow size XLx4192 | #Discount BIKE HELMETS ...

HootOwlPot


hello. My dad has just bought me a bike which has been one of my lifelong dreams since I am really overweight and would like to lose a few pounds before the next school year (June). So, basically I have 5 months to complete this task. My bike is just a normal bike. It's not a BMX and it doesn't have gears and shit; doesn't even have handbrakes, but I do manage with the footbrake.

See, I don't even know my weight or my BMI (my waist circumference is 34. That's as far as I know). We don't have a bathroom scale at home but I am fully aware that I am overweight. So my questions are as follows:

1. How long should I ride my bike and how many times should I do it per day? I just started yesterday and I read somewhere that it should be at least 30-35 minutes. I finished within 30 minutes yesterday, but today I did it in 35. Should I do it before or after breakfast? I do it in the morning when I'm still up and everybody's still asleep (I have a weird sleeping pattern. I am up at night and I sleep during the day). I also do it only once a day since, like I said, I am asleep during the day. I also don't like being seen by people.

2. How many pounds do you suppose should I lose in, say, 2 weeks? I mean, I'm not expecting too much, but maybe 2-3 would be great because then I could just keep it up and I still have a few months to achieve my goal.

3. Do you think my sleeping pattern could be a problem? I know staying up late and stress could actually make you gain a few pounds and of course I wouldn't want that, but it's just like a normal sleeping pattern, though, isn't it?...only in reverse. But still, better safe than sorry.

So there...Also, any tips would be MUCH appreciated.

Thanks.



Answer
I lost a lot of weight riding my bike, and I really love it, so that makes me an expert. 8^) NOT.

First of all you want to make sure the bike is adjusted for your size. Seat height, seat placement forward/backward, and handlebar height. Those things make a huge difference in how comfortable your bike is, and if it's not comfortable you won't ride it. Look on YouTube for bike-fitting videos.

Secondly, you should understand that exercise and diet work together, they are like two sides of the same coin. Either one alone won't work nearly as well as both together. In my experience, the low-carb diet works best.

You should ride as far as is comfortable for you at first. If you overdo it at first you get really sore, and you'll stop. You have to learn to 'challenge yourself', that is, to ride as far as is comfortable and then just a little more. I got up to 5 miles in a couple of months and then 10 miles in about six months, but you will probably do better. My longest ride was 20 miles, which was an accident (I got lost!)

For a single-gear bike it's best to stay on the flat, avoid hills. Stay off busy streets. In fact, look on Google Maps and click on the bicycle logo and you see all the bicycle lanes and dedicated bicycle paths in your neighborhood.

Inflate your tires to the highest of the range on the tire, like if it says 40-50 lbs you go 50 lbs. The harder the tires are, the easier the bike is to pedal. You'd be surprised how much difference it makes! I inflate my tires 15 lbs over the mfgr's recommendation. It works fine for me, but I can't recommend it.

I wouldn't ride before breakfast, when your blood sugar is low and you have no energy. Half an hour after breakfast is optimal. Bring a water bottle and drink lots of water--very important! Drink a little more water than you think you need to.

Find a helmet that's comfortable for you and wear it always. If you ride at night get lights (flashing red light in the back) and a reflective vest. Car drivers don't SEE bicycles! So be paranoid of them.

Keeping strange hours probably doesn't have any effect on your weight. I'm a night person myself. But if you want to get into a 'normal' schedule, riding your bike in the afternoon will tire you out so you can go to bed at a more normal time.

You will see no weight difference in 2 weeks. 2 months maybe. Don't think about weight. Think about 'challenging yourself', wearing yourself out, riding a little farther than you did last month. Losing weight is a bi-product, an incidental.

I listen to audiobooks on my cellphone. It's probably not as safe, but it's an incentive because I always look forward to hearing the next part of the story. 8^)

Is this a good pair of roller blades?

http://www.amazon.com/Rollerblade-Spiritblade-Mens-Skate-Size/dp/B001FOQ86U/ref=sr_1_1?ie=UTF8&s=sporting-goods&qid=1282865028&sr=8-1

I am looking for a good pair of roller blades for around $100 and these look nice they are $170 marked down to $60 so I was just wondering if this brand is good or if these roller blades look good?



Answer
FYI: Rollerblade is only one company. Inline skates is the generic term for the sport and skates.

Rollerblade is one of the two major companies (they made inline skates practical and started the sport) along with K2. Their skates will be durable and good.

The SpiritBlades are a beginners skate for people who are not intending to get seriously into the sport. $60 is a good price for them and is available by some shops like Dick's where you can try the skates on before buying them.
The wheels are smaller than I would generally recommend. If you skate much, you will be replacing your wheels as they wear out. There are companies that make wheels that are much better than the ones that come with the skate but 80mm is the smallest size with a lot of choices.
Larger wheels roll better than small. I paid about $104 for some Rollerblade Activa skates for my girlfriend last year. You might be able to find a good deal on some higher level skates than the SpiritBlades and stay in your price range.

Almost all beginners can learn on skates with up to 84mm wheels.
90mm wheels will be difficult for some beginners.
100mm wheels will be difficult for most beginners and are even too large for some experienced skaters.

It is much better to buy the skates in a store than online, especially for a beginner.
The fit is important and you cannot try them on when ordering online. Don't hesitate to ask if the store has a sales person who skates regularly, some skaters work at sports stores as a second job to get discounts and they will know more than regular shoe sales people about how they should fit.
The skates should fit snugly all around the feet without pinching anywhere. You want the skates to become part of your feet instead of letting the feet move around in them.
Different brands and models will fit different people better. Try on as many as you can find.

Don't forget safety gear.
Head hits are rare but can be horrible. A bicycle helmet is good enough for normal skating. If you want to do tricks, invest in a "multisport" helmet. They are hotter but better protect the sides and back of the head.
Wrist guards will help keep the skin on your hands when (not if) you fall. Saves you significant pain while healing.
Knee and elbow pads depend on your level of balance and aversion to the risk of scraping up your knees (more likely, but less than hands) and elbows (less likely).

Check online if you have a local club. They can help you find good skates locally and learn to skate well.
