  • Making a Pedal Pitch - Possible Research Topics the Following Are Some Ideas for Guiding a Brainstorming Session
    Intel® Teach Program Designing Effective Projects Making a Pedal Pitch - Possible Research Topics The following are some ideas for guiding a brainstorming session. Numbering corresponds to exercise numbers. 1. Wheel diameter: Is it possible to fill front panniers so full that the bags limit the turning radius of the bicycle? What is the turning radius needed for streets that intersect at various angles? Does the size of the wheel affect the turning radius (compare a BMX bicycle with a mountain bicycle)? Is there a relationship between wheel diameter and coasting distance? 2. Banking of race courses: Calculate the speeds for which a particular bicycle racecourse or velodrome is designed. 3. Reading and making graphs: Create a time and distance graph to describe a summer biathlon competition (cross-country cycling and marksmanship). Create a time and distance graph to describe an Ironman Triathlon (running, swimming, cycling) 4. Bicycle falling over: Has a bicycle or tricycle falling over been used in comedy? Do they fall over at fast or slow speeds? Why are bicycle helmets needed? Who wears them … in your community, in your state, nationally? For a child, teen, or adult, what is the sitting height on a typical tricycle or bicycle for each age group (hot wheels, small bicycle, BMX, trail bicycle, touring bicycle, racing bicycle, an old fashioned bicycle with large front wheel and small back wheel, unicycle)? What are safe ways to transport a child using a bicycle? Is a child safer seated behind the rider, in front of the rider (using a specialized seat and pedals), in a towed cart?

  • Trike, Bike Or Recumbent?
    Cycling with MD 1 Do you want to cycle again? If so, what would suit you? Trike, bike or recumbent? My favourite activity used to be cycling. Unfortunately Meniere’s stopped that. Some years after diagnosis I had gentamicin injection in my MD ear which resulted in balance issues. However with vestibular physiotherapy my balance improved. I started to walk more, hike and looked at ways of getting back on my bike without fear. However, for me two wheels are not suitable so investigated tricycles and ended up with a recumbent trike. Some MD sufferers are still riding a two-wheeler bikes. So, if you were a cyclist and want to get back on your bike the following my help you take the next step. IMPORTANT: • Please remember, we are all different! • There is a lot to consider if you want to ride again. • We are all at various stages of Meniere’s so it may not be timely. • Cycling is not for everyone. • When the time is right, you will know. • Maybe you have said goodbye to cycling and have decided to try something new? (The following information is from sufferers and bike experts.) SUMMARY OF RESEARCH • Some find they can get back on their bike and have no problem • For some touring or mountain bikes suit as they are more stable • Any balance concerns, think about stabilisers until you feel confident. Tricycles • Before you buy one you need to understand cornering is different to riding a bike. • If not steered correctly, your standard tricycle can you can tip.

Add a front basket and rear rack easily to let the bike do the work of carrying things. Most cruisers will accept fenders to help protect you and the bicycle from the rain and snow. The Hybrid Bicycle A hybrid bicycle is mix of a road and mountain bicycle. These bicycles offer a range in gearing and accept wider tires than road bikes do. Some hybrids have a suspension fork while others are rigid. Hybrid bicycles are great for commuting in the winter months because the wider tires offer more stability.

Great for utility, commuting and for leisure rides to and from the lake front.

It's expected to be three dollars a gallon by summer. You are hot, tired, unfit, overweight and fused to the seat of your car. Traffic is at a stand still from the freeway to your driveway. Commute time is eating away at your life, reducing time for family, friends and exercise. Walking would be a faster, healthier and a more efficient form of transportation but work/school is too far away. We remember learning how to ride our first bicycle with our grandparent, parent or older- sibling. Our learning how to ride it is often the only thing we remember about a bicycle. Learning to ride a bicycle is so important that it is considered a developmental step by pediatricians and child psychologists/psychiatrists.
