The auto industry is giving us the same lies that they did in the fifties and sixties about the future of cars, but now they promise pollution free machines, hydrogen-electric computer controlled cars. They even tell us that they can put more cars on the freeway; bumper to bumper at racing speeds. Some want to fill the skys with flying cars, as if fuel could get cheaper. That sounds insane to me.

PRICE OF FUEL. I can't stand to hear people whine about the price of gasoline when they should be raving about the 'true' cost of motor vehicles. According to the Dept. of Labor's Bureau of Labor Statistics, car ownership costs are the second largest household expense in the U.S. In fact, the average household spends almost as much on their cars as they do on food and health care combined for their entire family. If your annual cost of owning a motor vehicle is close to $6400 (as is the American average) you are still paying only a small fraction of the real cost (cars.com). The war for the last of the worlds dwindling oil supplies has cost us $200 billion and is still going up. That’s over $600 million per motor vehicle in America alone (mind blowing at any degree of error). If the 50 thousand American casualties (43 thousand fatalities, not including the lung cancer victims of exhaust poisons) caused annually by cars were caused by war, American wars would become much too unpopular to wage. (iraqbodycount.net/)

There are 204 million motor vehicles (140m cars) in the U.S.A. 600 million worldwide, using 40 million gallons of gasoline a day producing Carbon dioxide emissions of about 7 billion metric tons annually and shooting up because of the governments misinformation campaign about global warming.
The world population is approximately 6.5 billion now, but an extra three billion people are expected by mid-century requiring three times as much energy. Obviusly the world needs voluntary populatuion control, but that’s even less likely to happen than cheap energy.

Hydrogen fuel is a fantasy made up by the halfwits in the white house to give us false hope in the present administration. Hydrogen takes more energy to separate from oxygen than is produced from burning it, so it will never be good as a fuel. The only way to make enough electricity is to build thousands of nuclear power plants, and there is not enough uranium on planet earth to fuel them. Solar vehicles are a dream, and as with any high tech solution it takes almost as much energy to produce the equipment as is returned over its life span. Brazil is going to to be the first to convert to ethinal (from sugar cane) but ethinal can only serve to depleat the soil, like strip mining. Bio-diesel from algae is the best bet for keeping industry moving, but it’s not going to be cheap, and it will take way too much water. To replace Americas $150 billion a year foreign oil addiction would cost over $300 billion to build enough algae farms. And every one will need new diesel electric hybrid cars, don’t think that biodiesel will cure the air pollution problem.

As long as petroleum prices are kept artificially low (gas tax revolts, subsidized acquisition of oil by war, denial of global warming), the post industrial world will continue it's happy addiction! Eventually we will all have to pay the price for not changing our “way of life” when it was easy!!!

Don't worrie, humans will never get rid of cars, there will always be the rich that do anything they want. In fact I predict that the amount of cars will only increase, untill hell freezes over.

however I do think that some cars will evolve into leaning trikes with pedal electric hybrid motors.

MASS TRANSIT. Railcars floating on huge magnets....but can they be built in time? Are there problems with with magnatism? Will the corperate overlords alow it? There is an article in the December '07 issue of Popular Mechanics. search Maglev trains.

HPV's. Modern geared cycles are the most efficient transportation machine ever devised. In terms of energy input per mile nothing else comes close. I burn only about 400 to 800 calories to ride my trike 10 miles round trip. That’s equivalent to a large american breakfast.

I pedal a combined weight of 400 to 450lbs 30 miles a week. If I had a lower gear of 7 inches I could climb the very steep 14 % grade with a QUARTER TON. It’s all a matter of gears and patience.

Fueling your engine with concentrated carbohydrates (more than 10%) will sap your energy. I use diluted fruit juice with electrolytes (alacercorp.com). Stretching my legs during hard climbs and after hard workouts helps prevent muscle pain, but massage is better.
Saving so much money by not owning a car I never worry about how much my cycle weighs and slows me down, because I know that the payload and my self will weigh much more. I make a point of carrying more weight than I need just to help build muscle that I need to over-come the limitations of human powered vehicles.

BIKES. There is a new trend in bikes to make them more comfy for short distance riders. They pushed the seat back and use sit up handlebars. They are not as expensive as recumbent bikes but not as comfortable. Regular bikes have not changed much sense they started using sprocket drives: better gears, different handlebars, all designed for racing. People are obsessed with speed; they pay way too much to get rid of a few ounces. That’s what fuels the bike industry. Unfortunately racing equipment is not strong enough to haul cargo.

There are a few old style cargo bikes (workcycles.com). Recumbent cycles with cranks lower than the seat are the easiest to use. Mountain bikes are good for exercise and ok for pulling a trailer short distances. Xtracycle.com makes add-ons for regular bikes that hold more cargo.

Even the chineese are experimenting with new designs, like a sliding pedal system. See Velovisions.com

TOURING BIKES

In my quest for the right touring bike I learned many things.

Most factory bikes are so light duty that most are limited to a 275lb load by the manufacturer.

Only a few have heavy-duty dropouts, the weakest part of a bike unless you use cheap wheels. Front wheels are effectively twice as strong as rear wheels because of the lopsided dish pattern of the spokes on the rear wheel. So a tandem wheel with symmetric spoke dishing and a drum ‘drag’ brake is very useful for fully loaded touring, and descending a mountain.

The things that make a bike easy to balance at slow speed are:

WHEEL BASE: SWB bikes have a faster minimum speed than the LWB’s because the front wheel changes direction quicker than LWB bikes. This is mostly due to reaction time.

CRANK HEIGHT/ SEAT ANGLE: Vertical positions are easier to balance but horizontal seats are more comfortable on long rides. So the best compromise would be to have the crank 4” below the seat.

TRIKES. Tricycles are much easier to haul cargo with than bikes because of the slow speed balance problems when climbing steep hills. Even if you have a good trailer, balancing perched on top of two wheels can be a real work out.

Riding trikes on the sides of cambered roads or turning fast can present a leaning problem. There are trikes that ride like bikes but still has the tripod effect for hill climbing .One with cargo space under the seat, Stite’s trike is reviewed in RCN #82. (stitesdesign.com) And another that all three oversized 26" wheels and the seat lean into the turn. (tripendo.com)

Turning a budget priced cycle into a machine that can handle cargo is mostly a matter of up grading to stronger wheels and a way to mount the payload. My Ez3-usx trike is reviewed in RCN #89.

Tadpole trikes (two wheels in the front) can accept an electric hub motor much easier than a delta trike (two wheels to the rear), but only if you give up the chain drive, except in the case of the 'Side Winder' trike. But a delta trike is easier to mount cargo on. I have a box behind the seat, and a rack in front. I think Front wheel drive delta trikes and the Light foot trikes are the only ones that are good for hub motors.

I don’t like delta trikes with only one drive wheel, they have steering problems when climbing hills with a payload. But they are good for hard braking from high speed if the rear brakes are on one lever and you have a front brake to even it out.

Tadpole trikes have braking problems, you can loose control with hard braking at high speed because the pressure on the brakes are not always even and the brakes are on the front wheels. Also pot holes and bumps can have effect on the steering,

TIRE PRESSURE. The bicycle industry try’s to censure the instability of tadpole trikes. Top-heavy trikes and low tire pressure (65psi) are the biggest dangers.
I know a man that lost control of his EZ3 tadpole trike because at 30 mph down hill there was too much side-to-side bounce. Brake steer effect can be very dangerous, if your feet drop to the ground they can be pulled under the trike and mangle your bones. That's why you need clippless pedals on trikes.

Tadpole trikes will wobble from side-to-side due to the momentum of the riders legs as they go through a pedal stroke also. Some tadpole trikes do this more than others. The determining factor is the size of the rear wheel. The bigger the wheel the worse it gets?

Delta trikes are much safer than tadpole's. I have never had any of these problems.

RIDING IN THE RAIN

While riding a recumbent cycle in the rain maybe harder to stay dry than a ubiquitous vertical bike [which take nothing more than a rain poncho and gortex gloves]….Riding in the ice cold rain can be a pleasure if you have water proof shoes and a good breathable rain suit. Warm rain is more difficult because you will seat more and still be too cold when removing the rain shield.

A light rain is ok if you generate enough heat to evaporate it.

Wool is the best wicking material there is, cotton is the worst by far as it holds the moisture next to the skin. Polypropylene stinks with just a little seat, but I did find some new poly shirts that were developed by the military industrial complex with silver impregnated threads to keep the bacteria from growing....and it may wick as good as wool?

All breathable rain shields do not breathe enough for hard exercise, so I try to slow down in the rain. And hope that most of the moisture ends up between the wool and the gortex.

The only rainjacket that has a chance of working is one with vents front and rear and under the arms.

If a rain poncho isn’t enough weather protection for you, it is possible to retrofit your trike with a Velomobile body. There are folding trikes that are easier to transport but they still won't fit on a bus.

Cold weather equipment:

Warm cap; extra large shoes for two thick wool sox; snowmobile mittens with liners (ski gloves are not warm enough under 40 degrees)

Layers like 2 scent control polypropylene shirts; wind proof jacket; fiber fill vest; and pant liners for the cold wind.

SPECIAL NEEDS. There are bikes of all sorts out there, I know of some one in origon that designs and builds custom bikes. And there is this hand crank bike: well.com/user/kjcole/Bike/handbike2.html.
And a hand pedal trike at Angletech.com.

QUIKES. the only quadrocycle in america is an over priced sport toy. Hopefully this will change soon because they are better for weight handling. See RCN#80. There is a cheap light duty quad at Rhodes Cars (4wc.com)

There are new designs, like a sliding pedal system (Velovisions.com), and other improvements like short cranks and Rotor cranks with elliptical chain rings for knee pain (rotorcranks.com), although pushing your toes forward as much as possible on the down stroke is a much less expensive method to keep your knee caps from pushing up when pedaling hard, Power Saver pedal pendulums can help also (hostelshoppe.com). Large cushion seats for recumbents are essential. Some people think they can save money with a cheap trike that has a minimal seat (that will eventualy hurt their backs), under seat sterring with laid back seats is essential for carpul tunnel syndrome and bad backs. And there is a puncture proof tire systems (notubes.com). There are trikes that ride like bikes (tripendo.com, stitesdesign.com & culty.de) and quadrocycle trucks (brox.co.uk & a-v-d.com). But pedal powered busses are the best idea yet for big cities. (pednet.org/newshumanbus.html)

VELOMOBILES. are mostly tricycles with aerodynamic bodys.
In 1974 an American reached a track record of 43 mph on a recumbent bike in a velomobile wind fairing. 1986 the record speed for a human powered vehicle was 65mph. 2002 the official world record was 81 mph. A rider who is used to riding frequently can hold a speed of 30mph quite a long time in an aerodynamic velomobile.

For most people, the rain protection is certainly the main characteristic of a velomobile. When wet, the unfaired vehicle is no fun. Besides the rain protection, the cold wind is certainly as important. In wintertime at temperatures below 40 f, the choice of the right clothes is a risky game between sweating and freezing. In contrast, the temperature in velomobiles is controlled by air flaps and not by changing clothes. Admittedly, velomobiles are quite expensive at first. But those who decide to use their velomobiles for commuting can save a lot of money over a long period of time.

CRANK SYSTEMS.

Previous attempts to deal with the dead spot have resulted in some interesting things like The K-drive double jointed crank arm set with gears and chains, developed for a longer power stroke, but too complex and heavy for modern ‘performance’ cyclists.

‘Power Saver’ pedal pendulums ( RCN #57 page33 ) lessons the Plyometric hamstring rebound by shortening the upstroke, but didn’t work with “clippless” cleat pedals. read more

'Power Cranks'These are trainers for learning to crank in an even ballanced rotation with both legs.

Schlumpf Two Speed Cranksets, expensive but much better than the external gears for utility cycles that need many more gears, they can be set up with three chain rings, giving you six crank gears and 14 gears in the rear hub.

Short cranks can help improve your cadence but only if you reduce your gear ratios enough, and your anthropometric characteristics are considered in choosing the crank length. A good reason to use adjustable crank arm shorteners and a computer. Possibly a waste of time for most people.

PEDALS. I used BMX pedals for a long time but later discovered that with clipless pedals I can get a much faster start and climb hills easier. read more

IMPROVED TIRES.
I had to reinvent how to keep tires from being punctured, tires with in tires!

Ten years ago, after finding road testing not accurate enough, a machine for testing tire-rolling resistance was built and they found that wider tires rolled easier than the narrow tires, and that small diameter tires rolled easier than large diameter tires.

ok larger wheels have less rolling resistance than small wheels because of the momentum factor, but if you can get high pressure 2" wide tires in 26" or 20” (100psi ) they should have close to the same rolling resistance.

So why should the fatter small diameter tire roll better than the larger narrow tires? The answer is at the contact point with the road. Narrow tires will have an elongated shape, whereas the fatter tire will have a rounder shape, therefore we can expect more energy to be absorbed by a narrow tire. I use 2” wide 110-psi 20” tires for the rear of my trike.

Bicycle wheels can be very difficult to maintain perfectly round because of the spokes. But Carbon fiber wheels with out spokes that use rim brakes will be way too expensive because the rims wear out fast.

MTB tires on recumbents? the only one I would recommend is the Hutchinson Python New Generation 80psi, and only if you need to ride on bad roads and trails.

Specialized Armadillo is a good almost puncture roof tire but thay have a problem with the tread coming off. That's why they are the only tire with a warrenty, I know some one that got a free replacement even though the tread was almost worn out.

NOTUBES.COM is the stuff, unfortunately the goo is so motion sensitive that it must be replaced twice a year. It would be better to use a steel belted tire if they made one.

Kevlar belts are not much good, I used a schwalbe marathon for a year , and had another years worth of tread on it, but I got a glass puncture that created a bulge in the tire by destroying the casing…. I discovered that I could put that tire into another 1.5” and have he best possible liner but I had to cut off the bead first. That was after wasting $36 on Spinskin tire liners which disintegrated in the tire (another rip off).

KITS.Flevobike developed a kit together with student engineers (velomobileusa.com). In 1993 the Alleweder came into the spotlight with the one-year bike contest organized at the technical university of Eindhoven. An Important part was the one Hour race in which competitors had to prove their vehicles were practical and speedy. They had to travel at least a 22mph average with 33lbs of luggage. The contest got a lot of attention in the news media.

SNOW AND ICE. Riding on ice is very dangerous for a bike, but a trike needs nothing more than good traction. I intend to build a tadpole trike with a 26" rear wheel for a studded snow tire. Also it will have a rain fairing with lexan bubble over my head, a cargo box, and a hub moter built into the back wheel. Single traction delta trikes work ok on sanded ice with studded snow tires.

ERGONOMICS. Something else to consider is the difference in ergonomics between ‘bend-over’ and ‘layback’ seating. The well-known bend-over-the-bars bikes (of who’s design was frozen in time by a racing rules decree in 1934) designed for speed with disregard for comfort, requires gravity and your arms to pull you down onto the pedals. Recumbent lawn chair bikes help build muscle when pushing between the seat and the pedals. However due to the lack of movement of the hips to take advantage of the leverage of long cranks, you get better ergonomics (less knee pain) with short crank arms (130 to 150mm in place of the usual 165 to 175mm). But a lower gear is needed for hill climbing, 14% shorter cranks needs a 14%lower gear.

Ergonomic angle is what makes a bike fast!!! The more bent you are the harder you can push.

The higher the pedals are in relation to the seat the harder it is to keep your feet on the pedals...??, so some use cleats and break their legs, but realy knoby pedals help.
Pedals with cleats convey more energy by helping your foot threw the dead zone at the top of the crank rotation by pulling threw the bottom of the rotation with the other foot.

Most people think the ubiquitous old style bikes are better suited to climb hills because they don’t take the time to develop the new muscle sets that recumbents use, pulling your self down on the pedals may be better for sprinting but not for maintaining more power [page 19 Bicycle Design-by Mike Burrows]. And there is a balance problem with long wheel base bikes on very steep hills because they can’t change direction fast enough to balance at slow speeds.

If you have lower spine problems a seat with a lumbar support really helps. For carpel tunnel syndrome, under seat steering is needed, over seat steering is for racers, even if the long handle bars on long wheel base bikes do help keep the front wheel steady. Twist shifters are a pain to use in wet weather, with gloves or if you have wrist pain.

Narrow seats found on the old style bikes can aggravate your hemorrhoids. Most of the new recumbents have seats with large foam cushions that are more comfortable than I ever thought possible.

PEDALING BACKWARDS

On a bike with an open chainline (and a long 'bent chain), you can try this by just twisting the chain into a figure 8. (BB and pedals will unscrew if you do it for very long.)

I've done it. I think I could do more of it, as a way to change the way my muscles are used on long rides.

There was a company showing a Schlumpf-like BB device that allowed you to power the bike by pedaling forwards or backwards. They were pitching it to mtb riders to use on steep climbs. Company went bust before they got to trying it on 'bents. Seems to be just too weird for people.

TIPI-TOE MANEUVER

There is a zone in the crank circle where there is no power; because when your foot reaches the end of the push stroke the opposite foot is a quarter turn from the right place to push. To help your foot reach the right spot the foot at the end of the push must swipe threw and pull back, with recumbent cycles this is mostly just helping gravity. If you don’t wait until the foot is in the right space, you can push up your kneecap up, causing the infamous knee pain.

There are several mechanisms invented for stand up bikes to help your foot through this dead zone. Clipless pedals (cleats) or straps, and now a very expensive Rotor crank that eliminates the dead zone (rotorcranks.com).

Pedaling my 400lb sport utility vehicle (RCN #89 USX trike) gave me such pain in my knees that I had to back off from pedaling hard and try short cranks, which gave temporary relief, but soon led me to damaging my knee-caps again. As I was thinking about spending around $200 on clippless pedals and shoes, I reinvented a maneuver that places my foot at about 80 or 90 degrees to the crank arms at the beginning of the push stroke.

I push my toes forward as much as I can with out pain (it can’t be done with boots on) positioning my bones in such a way that keeps from pushing my kneecaps up. It’s amazing how much harder I can push now with out creating pain

At the end of the forward push I push down “swiping threw” and pulling back with my foot still on top of the pedal.

I don’t need clipless pedals with this maneuver but I do use BMX pedals and place the top of my foot arch on the pedal rather than the ball of my foot.

Short crank arms are not needed but they can help the foot reach the right position. One person told me that using this maneuver on his “stand on the pedals” mountain bike felt like running on his tippi toes.

Apparently some people can experience toe numbness from “anterior tunnel syndrome”. So don’t force your feet into this position.

I think the primary cause of knee pain is simply pushing before the right spot is reached. That’s why it is still possible for me to damage my knee with this maneuver.

I did move the seat closer to the crank to get more power to the pedals, but still there is a limit to how hard I can push with out lifting my kneecaps. And of course if I could lower the gear-inches below 10.5, I wouldn’t need to crank so hard, but it wouldn’t give me more power.

Then a faster cadence would be possible for most people. I can’t pedal as fast as some because of my large leg muscles. I believe that Power Saver pedal pendulums can help with cadence speed, but no one in America sells them.

I don’t think that the crank placement affects this maneuver but for comparison my crank is 4” lower than the seat.

power is best delivered to recumbents power cranks via the momentum of a fast cadance as aposed the leverage ability of french racing bikes and its mountian bike variation. (stand up bikes)

WALKING. While walking may not be the most efficient use of leg muscle, it is the least harmful our thin biosphere. And walking helps align the spine; it is simply the best for of exercise, and the best way to loose weight!!! cycleing burns to much blood sugar too fast.

And running should be faster than ever with spring loaded boots

LEG PAIN. Stretching and massage are the best, but prevention is better. Learning not to push in the dead zone of the crank circle is essential. Short crank arms can help, but Rotor cranks eliminate the dead zone that pushes your knee cap up.(rotorcranks.com) And I am working on an idea of using pedal pendulums to help the foot threw the no-crank zone.

DRIVE CHAINS. I used to think that longer chains would be a problem. The truth is that they last longer because they only stretch while engaged in the sprockets. My mechanic tells me that Sram is not the best chain, Shimano Hyperglide is the best of three grades, KMC being the bottom of the line.
On recumbents more of the gears can be used simply because the chain has more flex.

CHAIN LUBE 3-IN-1 is the same as Prolink but not thinned out with petrol. Demon tech has really bad fumes and will not dry if applied too heavily. Purple Extreme is the best wax based lube but has a hard time drying in the winter.

BIKE LOCKS I use kriptonite new york Ubar shackle because I want to keep my expensive bike, But now some one came up with something better: Master Lock Street Cuff Bike Lock... I may need one of these, they are 3 to 4 inches ID and made to be bolt cutter proof. they are BIG!

POWER ASSISTANCE. Iceland will be the first country to give up the use of petroleum, the usa will be burning it as long as possible. People are improving hydrogen fuel technology to burn in cars, but hydrogen is already available for cycles, in the form of improved battery systems for electric hub motors (lightfootcycles.com/power). This could be a good way to keep car drivers off your back on narrow roads. Pedaling a cargo trike up a steep hill will be slow and people are so hyped up on caffeine that they just can’t stand it some times. There are several electric hybrid bikes for lazy commuters and there are going to be a lot of pedal assisted electric cars like the Twike. (twike.ca)

Electric hub motors are best but if you must have a gasoline engine, get a four stroke, they are less polluting.

TRAILERS. Trailers are the best way to haul light cargo. Not all recumbent bikes can use the B.O.B. trailers and two wheel trailers are more stable with a load, Cycletote trailers are my favorite. (cycletote.com) I don’t like cloth panniers because they wear out too fast. Bikes at work’s trailers are the strongest. (bikesatwork.com)
A really good way to have an electric motor that you don’t have to carry with you unless your going to need it is to have the motor and battery on the trailer. (thunderstruck-ev.com/motobob)

LIGHTS. Effective lighting for roads with out streetlights can be expensive. Even two $50 LED headlights are barely enough. I find it very difficult to balance a bicycle at slow hill climbing speeds with out a wide visual reference.
I would rather spend $200 on a double quarts halogen head light with NiMH rechargeable system. The LED's effective power supply does not last as long as they say. So even tail light batteries should be rechargeable. A flashing white headlight will help make you more visible.

SUN BURN. Roll on vt E oil is so much better than sunblock.

GEAR INCH FORMULAS. Obviously every one is different, even at different times. So you can use this only to for estimation with 170mm cranks. If an average healthy man can sustain a power output of about 0.33 hp, or 10890 ft-lbs per minute, up to 45 minutes. Or .2hp = 6600ft.-lbs/min. for 1.5 to 2 hours for climbing those long mountain roads. If you're trying to climb a 14% grade with a combined weight of 390 pounds with a power output of 10890 ft-lbs/min, divide by (.14 grade x 390 lbs) = 199.4505 feet per minute. Now, if your cadence is 80 rpm at the crank, and you're moving at 199.4505 ft/min x 12”= 2393.406 inches per minute, divide by (80rpm x pi)= 9.52gi. [70rpm= 10.88gi and 60rpm= 12.69gi]. It is best to calculate at 80rpm cadence to give yourself room for error in your strength level. If you’re forced to slow down to 60rpm you’re pushing too hard. Over 80rpm your wasting too much energy just heating your legs. An approximate 14% grade is the maximum that I can pedal aprox. 390lb at 12.5gi. (slower than 60rpm) resting my legs every 20ft or so. Don’t worry most hills are never more than 9%. To move a quarter ton up a 10% grade 10.4 gear inches would be needed.

The best way to measure the road grade is to hold a level, one end to the road surface and measure the other ends height when level. The grade is the vertical distance divided by the horizontal.

Gear inch: driving sprockets divided by driven gear sprockets, multiplied by measured diameter of drive wheel and tire. A set of gears equaling a 20” is like pedaling a 20” wheel with out gears. See bikeatwork.com for more info.

what gear does the short cranks feel like?. 170mm crank minus 155 devide 170%=8.823 then 22sprockets plus 8.823%= 23.9 sprockets.
