Cycling is one of the recent hip activities at the time and we see people riding cycles everywhere. I have been posting cycling safety but I found it very important to know the safety guidelines as accidents with cyclers are rising .
Safety…Did it, done it, doing it tomorrow
Gitzel was riding on a car wrapping up my long long night, when I was by Banyan Garden on the West Kowloon Corridor at around 10.pm, I saw two bicycle riders riding on the main road towards Mei Foo, right where peope take off the corridors to Mei Foo. Those riders has no rear light nor reflector and they seems enjoying their time chatting and pay no attention to the traffic at all. I personally think it is real dangerous .
A regular sedan , Japanese made usually weight about 2000Lb , european made weight about 3500 Lb , this is our M1, M2 is the weight of the bicycle,which I don't know
Speed Limit of the Corridor at 70Km/h (V1=63.7941 feet per second), even when slowing down to 50 km/h (V1=45.5672 feet per second)
Mathematically it is best described by impulse, momentum and it's roughly an inelastic type of collision
m1*v1 - m2*v2 = F*t
m1=mass car 1
m2=mass car 2
v1=velocity car 1
v2=velocity car 2
F=crash force
t=time in which the collision occurs
v is in ft/sec 0.911344415 × km/h = ft/sectime of collision (t) 0.1 second
I can not do the maths because m2 and v2 is unknow ,but
Can you imagine what the force and impact will be in a Collision? I'll tell you that the force is in Tons and this could likely be Fatal.
Guys,
- Plan your route according to your ability
- Know the rules and responsibilities you have as a bicyclist
Bicycle Laws(see below) - Consider the benefits of wearing a helmet - you will be more visible to other drivers, better protected against injury, and motorists have more respect for the cyclist wearing a helmet
- Carry waterproof clothing
- Carry identification
- Wear eye protection
- Wear padded gloves
KNOW Your Bicycle
- Each day before riding check your brakes for wear and tires for appropriate inflation - each week give your bicycle a thorough inspection
- Use a seat pack capable of holding a spare tube; tools, flat tire repair kit; coins for phone call - or cellular phone
- Bring a tire pump (most can be attached to your bike frame)Fenders will keep you and your bicycle clean
- Rear rack and panniers or a bicycle trailer to carry your belongings
- Use a bell to signal to others that you are approaching
- Use a mirror for scanning behind while you ride but also learn the technique of looking back while holding a straight line
At Night or When Conditions Cause Poor Visability
- Front white headlight visible from 500 feet - approximately one city block
- Rear red reflector visible from 600 feet
- Mounted side reflectors visible from 600 feet
- A red rear flashing light is recommended to increase visibility
- Wear light colored clothing or clothing that is retro-reflective
The single most effective safety device available to reduce head injury and death from bicycle crashes is a helmet. Helmet use reduces the risk of bicycle-related death and injury and the severity of head injury when a crash occurs. Unfortunately, national estimates report that bicycle helmet use among child bicyclists ranges only from 15 to 25 percent.
Let’s change that! Everyone in the family should have a helmet and wear it whenever you’re riding. Here are a few tips for finding the right helmets for your family and other bike safety tips. Follow this advice and hopefully you’ll never have to come to RediMed with a bike related injury.
1. Wear the right gear
The right helmet and gear for you
First of all, all helmets should meet the United States Consumer Product Safety Commission standards. Select a helmet that fits snugly, sits flat on the head and doesn’t rock back and forth or side to side. Always buckle the helmet. Use the extra padding that comes with the helmet to ensure a proper fit for children. This padding can be removed as the child’s head grows. In addition to a helmet, wear proper fitting knee and elbow pads and wrist guards.
Wear bright, reflective clothing
Always wear neon, florescent, or other bright colors on your clothes and accessories when riding a bike, especially at dusk and when the weather is bad. Biking at night is far more dangerous than biking during the day, so avoid it if possible. Young children should never ride at night.
If you must ride at night however, do the following:
- Ride with reflectors that are permanently attached to your bike so they are good for daytime use, too. If a carrier is added, make sure the rear reflectors can still be seen.
- Add bright lights to the front and rear of your bicycle.
- Wear retroreflective materials on your ankles, wrists, back and helmet.
- Only ride in familiar areas with brightly lit streets.
- Always assume drivers cannot see you.
2. Maintaining your bike
Make sure your bike is adjusted properly
- Bicycles should be the right size. If necessary, make adjustments to make them fit you.
- Handlebars should be firmly in place and turn easily. Make sure you can see over them.
- Tires should be straight, secure and properly inflated.
- Gears should shift smoothly.
- Carriers should be added to the back of the bike if you need to transport items. Never try to carry things while riding.
Always keep your brakes properly adjusted. You should be able to stop quickly. If your bike has hand brakes, apply the rear brakes slightly before the front brake when stopping. When your hand brakes are fully applied, they should not touch the handlebars. Each brake shoe pad should wear evenly and never be separated more than 1/8” from the rim. Ride slowly in wet weather and apply the brakes sooner since it takes more time to stop.
3. Know the Rules of the Road
Stay on the “left” side of the road
Ride on theleft side of the road in a straight predictable path, single file, in the same direction as vehicles. Never ride against traffic. Young children are not usually able to identify and adjust to many dangerous traffic situations, and therefore, should not be allowed to ride in the street unsupervised. Children who are permitted to ride the street without supervision should have the necessary skills to safely follow the “rules of the road.”
Obey all traffic laws
Because bicycles are considered vehicles, bicyclists must obey the same traffic rules as motorists.
- Obey stop signs and stop lights.
- Always be courteous.
- Signal your moves.
- Never wear headphones while riding.
More than 70 percent of car/bicycle crashes occur at driveways and intersections. Before you enter any street or intersection, check for traffic. Always look left-right-left, and walk your bicycle into the street to begin your ride. If you’re already in the street, always look behind you for a break in traffic, then signal, to alert both cars and pedestrians, before turning either direction.
Stay alert
Watch out for potholes, cracks, expansion joints, railroad tracks, wet leaves, drainage grates or anything that could make you fall. Scan ahead and behind you for a gap in traffic before going around an object. Plan your move, signal your intentions, then make your move. If you’re not certain you can proceed safely, pull off to the right side of the road, and walk your bike around the questionable area. Remember to always cross railroad tracks at a 90 degree angle.

Hong Kong Law and Regulations _ Cycling
The following is a discussion of the ordinances (laws) and regulations of Hong Kong relating to bicycles. Like driving, there are certain fixed penalties including fines and jail time for careless and reckless cycling. Pedestrians generally have more freedom to move about as they are not considered vehicles, and there are apparently no rules or penalties against walking carelessly, though there are cases where such could be considered contributory negligence in the event of a collision.A bicycle is classified as a vehicle under Hong Kong law and as such you are required to stop when asked by a uniformed police officer or traffic warden, or else face a HK$2000 fine. You must also obey traffic signs and have your HK ID card with you at all times.
Summary of laws and regulations
Various regulations covering cycling and bicycles stipulate that:- Cycling is not allowed in road tunnels.
- You may not ride, carry or push a bicycle in any country park or ‘special area’, except on a designated cycling path with a valid country parks cycling permit, unless you are “ordinarily resident” in that area.
- Where designated cycle paths are available, you cannot ride on the road alongside.
- Many bridges have a sign indicating that cycling and pedestrians are prohibited. The sign has legal force, although there is no general law or regulation about cycling on bridges.
- Bicycles may not be rented to unaccompanied children (under 11), who also may not control a multi-cycle unless accompanied by an adult. An exception is when rental is made for use only on designated cycle paths.
- Any child (under 11) must be accompanied by an adult to ride a bicycle on a “road” (道路).
- A “road” (道路) does not include footpaths, pedestrian walkways, or designated bike paths.
- Every bike must have a bell, and no other warning system is allowed (such as a horn or perhaps even a loud shout!).
- When ridden at night (or in poor visibility), a bicycle must be fitted with a white light at front and a red light at the back.
- A rear-facing reflector is required, apparently at any time. It should be at least 40 mm diameter or equivalent.
- A brake must be fitted to any bicycle, tricycle, or multicycle wheel larger than 460 mm.
- Passengers may not be carried, except children under 3 years, in a “properly fitted seat” (Cap 374G Regs 51 and 53)
- On a bike, you may not transport dangerous goods [Cat. 5] (i.e. flammable substances) other than two 20-litre tins of kerosene.
- Cycling while under the influence of drugs or alcohol can result in a fine the first time, and up to three months imprisonment for a repeated offence.
- Electric bicycles and bikes fitted with add-on motors are considered illegal by the Transport Department, based on its interpretation of the law. (See TD Q&A, qu. 13)
- If your bike has a regenerative braking device, you must have third-party insurance.
- Cyclists have a duty to stop in case of accidents (if there is any damage, even without any injury)
