HPV bicycles 600+ mpg

Did you know a human power vehicle has gone over 80 mph ? They have a competition each year trying to break these records. The fastest use a recumbent type bicycle in an enclosed shell, very fast and aero dynamic.

Did you know a bicycle gets over 600 mile per gallon compared to the amount of energy in a gallon of gas when used in food ? Check out bicycling magazine. A recent college graduate did a study and compared all the food against fuel and went over 660 miles.

The bicycle has to be one of the most efficient machines ever designed. What type do you ride and how often ? If it's just for fun that's not bad but doesn't offset trips using fuel.

Re: HPV bicycles 600+ mpg
The type of bicycle I ride is a Rocky Mountain Moutain bicycle. I had to search all over the place to find a bicycle that wasn't made in China or that wouldn't cost me a fortune. Well, Rocky Mountain bicycles are all hand made and are made in Canada. I live in the D.C. area and ride every change I get. The transit system isn't very bicycle friendly here so I can't take my bicycle to work with me. They only allow bicycles before 7:00 am or after 9:00 am and then after 8:00 pm. This would make my work day extremely long and, since I study meditation and take krav maga this schedule would never work for me. We do, however, have many bicycle paths but getting to them is the big challenge. For example, I could ride to work during the warm months but, because of battling traffic to get to those trails, it would take me 1 1/2 hours to get there. The buses are a little more accommodating with cyclists. They all have racks that can accommodate two bicycles but there are no direct buses to Alexandria where I work. Just goes to show that there is room for improvement when it comes to supporting human-powered vehicles.

Re: HPV bicycles 600+ mpg

I just started biking this year, and I really love it. I'm pushing 40 and hadn't ridden a bike since I was about 13, so I was sort of wondering whether I was going to be able to pull it off. So far, I've been able to travel nearly everywhere I need to by bike and haven't had any problems. I'm fortunate to live in a smaller university city, so my longest round trip commute is only about 10 miles. I was surprised to find that it really doesn't take me that much longer to get places by bike, and depending on traffic patterns and how far I'm going, I can sometimes get places faster that way. It does take more planning to avoid dangerous intersections, and I don't know how committed I'm going to be in January when the temperature falls well below freezing, but so far, so good. I've cut my driving miles in half, and I'm in better shape than I've been in in years. Another side benefit is that I get to see what's going on in the community. When I'm in my car with the windows up and radio on, I feel a lot more detached from the rest of the world. My son is too young to bike very far with me, and my wife's health doesn't permit her to bike, so we have to take a car when we go anywhere as a family. The rest of the time, I really try hard not to drive.

I encourage everyone to bike, walk, take public transportation and carpool whenever possible. The biggest barrier for me to doing these things was in my mind. It's never too late to try something new.

Re: HPV bicycles 600+ mpg

Update, I rechecked and the article is wrong. The young engineer didn't allow for the food that he would have eaten even sitting watching TV all day. He only should have counted the extra food he ate to travel the 633 miles.

  In my own case I don't eat anymore when I bike to work 20 miles each way than I do any other days. I may drink one extra sports drink. So just to be safe let's say you eat twice as much.

That would have you effective mpg on a bike over 1,200 mile per gallon of equal energy.

In my case it's more like 6,330 mpg since I hardly eat or drink more, maybe 1/10th more.

  That is some pretty efficient travel. With only domestic organic foods eaten. No imported oil or pollution tp speak of. Now that's America the land of the FREE and home of the Brave !

Re: HPV bicycles 600+ mpg

I guess my intent was that a vehicle that could travel at car speeds would likely put you in a somewhat safer position in traffic, given the absence of a safe place to ride a bike.
Cars and trucks are certainly WMD in my mind as well. My community is a generally safe place to ride because it as been designed to be so. Once I leave my area however, what a nightmare. I work on a military base and have only a 5 mile commute. 1 safe mile in my neighborhood and 1 safe mile on base. It's the 3 in between that can test your mettle. To tell the truth, if I could wave a wand and make the cars and trucks disappear I would do it in a heartbeat.
I think a good many communities have tried to remake themselves into something sustainable like the neighborhoods of old and many have been successful to a large extent. I am not going to go Howard Kunstler here, but I think better design that takes mass transit, bicycles and pedestrian access into consideration,like much of Europe as you point out, may be what is necessary to get folks out of their cars and follow your recommendation to slow down and smell the roses.It really is the only way to go!!

Re: HPV bicycles 600+ mpg

I am a lifelong cyclist and I must respectfully disagree on a few points. First, let me say that I am fully aware that many gasoline powered scooters do pollute more than a car with it's emission system intact. No argument there.

Where I must disagree is the idea that slower is always safer. I have not found this to be true. In my area, and in fact most areas of this state(Texas), bicycle lanes are few and far between. Nearly any trip I make on my bike, I am in direct competition with cars and trucks for a piece of the right hand lane. In areas that do offer bike lanes they are often so ill conceived that they often make matters worse. Of course drivers who think the road is no place for a cyclist,and they are the majority here, can make bicycle transport a harrowing ordeal rather than the pleasure it should be.
There are some places in Texas (Austin being one) where it is possible to travel day in and day out with little difficulty. I don't live there. Wish I did though. I will continue to use my bikes as much as possible and encourage others likewise but it seems that,much as I hate to say it, bicycles are just not suitable for all areas due to heavy traffic,inconsiderate drivers, and lack of safe bike lanes.

Re: HPV bicycles 600+ mpg

I agree with your information. Bike lanes are great.

I still contend that slower is safer. Would riding your bicycle at 40 mph or even 60 make you safer on roads with no bike lane ? Would car respect you more ? I don't think speed would be safer. Only a safe bike path or getting all the vehicvles off the road and only have bicycles.

If we outlawed cars and trucks we could save over 43,000 lives a year. That's more than Iraq. I think we just found the qweapons of mass destruction, cars and trucks ! Let's slow down and bike and be safe.

I know it would never work. most people just won't slow down and smell the roses. Too bad. In Europe some seem to and bicycle and enjoy it.

Re: HPV bicycles 600+ mpg

The notion of "outlawing" personal vehicular traffic - I LOVE IT!  Don't get me wrong - I love having a car and the freedom it affords but imagine a world or at least a country (USA) where instead of all of us paying about $300 on average for our car payment, gas, insurance, etc - that money went into a fund that paid for amazing mass trasit.  Perhaps there would be allowence for travel beyond the "grid" to remote suburbs...I know it's far fetched but I'd do it and I think one day it may not be a simple choice but rather something that will be mandated - the cities are too crowded and getting worse - Bikes should be respected on the road and not seen as an inconvenience to some knuckleheaded drive in a hurry to nowhere!

 I think this site is about change and inspriing personal change which many (I include myself here) are afraid to make as we have grown acustomed to certain conveniences - we need to realize that it's about survial and the world we leave behind - it's time for drastic change in some cases and I would love it the notion of each and every household having 3.2 cars became a thing of the past and each household had 6.5 bikes!!!!

 Just a thought - Smiling

Re: HPV bicycles 600+ mpg

Don't be fooled by gas motorcycles, they can use less fuel but also make more pollution because most don't have any pollution controls. You also have to use the same road area as much larger vehicles and your speed can be very high so the safety is very poor.
A bicycle rides on the side of the road and more often has it's own bike lane. You can also go slower which is always safer, speed kills is not just the drugs. The bicycle also doesn't endanger others and safety is more that just you. It's all of us.

Re: HPV bicycles 600+ mpg

I have two bikes that I ride on a regular basis. The one that I use for exercise is an old Infinity recumbent. Very comfortable and very fast. The other is for trips to the grocery, hardware store and etc. It is an old Trek 800 that has been fitted with street tires, rack, and a very old three-speed rear hub.It is quite comfortable and just about bomb proof. I may soon replace it with a more modern commuter bike with internal gears and use it for my commute to work.
My daily driver is a motor scooter. It is a 4-stroke Yamaha and gets roughly 70 mpg. It is very fun and dependable but I want to try to go fuel-less as much as I am able. Have to say that riding my bike among thousands of cars every morning does worry me.

Re: HPV bicycles 600+ mpg

here are some links to the event. I plan to bicycle to it next year. I'm only 40 miles away and have never gone yet.

http://www.ihpva.org/dempsey_macready_prize.html

A new World record of 85.991 km was set by Fast Freddy Markham riding the Varna Mephisto. Fred is 49 years old and 20 years ago in 1986 he won the Dupont Prize of $30,000 for being the first cyclist to exceed 65 mph in an HPV (65.48 mph for 200 meters with a flying start). Apparently you don't bet against Fred when prize money is involved. (By the way, Paul MacCready was responsible for initiating the Dupont prize with his connection with Richard Woodward, who was in charge of Public Relations for Dupont).

There were some very fast lap times during the competition - 89.51 kph by Fred on lap 2 (5.662 mile lap), 87.52 kph by Damjan Zabovnik on lap 2, and 87.125 kph by Rob English on lap 2. In his 2004 hour run, Matt Weaver went 90.12 kph on his second lap (2 mile lap). Obviously higher speeds are possible for the HPV hour if conditions were ideal.

Prizes-serious money
1. $18,000 - Fred Markham - 85.991 km - July 2, 2006, Casa Grande Arizona
Nissan Auto Test Track.

2. $10,000 - Sam Whittingham - 84.215 km - July 31, 2004, Dudenhofen, Germany
Opel Auto Test Track.

3. $6,000 - Matt Weaver - 82.755 km - Oct. 9, 2004, Fontana, California.
California Motor Speedway.

4. $4,000 - Damjan Zabovnik - Special prize for fastest foreign competitor
over seven laps in Nissan event. Slovinia.

5. $2,000 - Rob English - Special prize for second fastest foreign competitor
over seven laps in Nissan event. England.
