To reduce some of the fatigue and stress of biking it's good to have an effective bike peddle stroke, it takes practice and focus but it will become second nature before you know it. Momentum is key, so keep a constant speed peddle stroke. You want to use the weight of your leg to push the pedal down, but you have to lift the other leg up at the same time because you don't want to be pushing against the weight of your other leg, that would waste energy. When done right it feels like your feet are floating on the pedals. You also want the ideal number of pedal strokes per minute, called 'cadence', which is around 60 to 90 strokes per minute, or RPM's (Revolutions Per Minute). In other words, you should aim to turn each pedal at least once per second. Try to keep your Cadence constant across all conditions. For example, if you start going uphill, you need to change down to a lower gear so that you can still spin the pedals comfortably and maintain your cadence. You will learn that this pedaling speed is very efficient because it's using the momentum of the pedaling speed to your advantage. If you pedal slow you can actually work harder, unless you're going down hill. It takes a lot less effort if you pedal faster at a constant rate, this is true whether you're riding on the flat or up a hill. Another bike pedal technique is to Push Forward with one foot pedal and Pull Back with the other foot Pedal simultaneously. If your shoes are clipped to the pedal it makes it easier but you can still do this technique even without attaching your foot to the pedal but it's not as efficient and sometimes your foot slips off the pedal. So concentrate more on just pushing the pedal forward then pulling back. As more power is needed I just push down more on the down stroke and or pull up more on the up stroke, that's if I'm clipped to the pedal.

Need a Bicycle Computer that Automatically shifts my electric gears, based on the speed I prefer, the angle of the road whether going up hill or downhill, and the preferred cadence or peddle speed. This way I have total control of how hard I want to work, and how quickly I want to arrive at my destination at a desired time. Also have the computer avoid cross chaining to decrease wear on the chains rings and chain.

Use the correct saddle or bike seat. Pro-cyclists use a hard narrow seat because of their style of riding, which is leaned forward so the contact on the seat is minimal. A leisure bike rider has more contact with the seat, thus puts more pressure on their bottom, which could cause discomfort and sometimes damage the Perineum.

I also like to use the Front Shifter more then the back shifter now. I leave the back shifter, or the Rear Derailleur Gear in the middle and use the front shifter as 1st, 2nd and 3rd gear. I only use the back shifter upper and lower gears when my front shifter is in 1st or 3rd gear for going up steep hills or for peddling down hill or for peddling fast on nice flat road with little wind resistance. You want to avoid cross chaining, which is caused by a bad gear selection that puts your chain on an extreme angle, which is bad for your the chain and gears. I have a 30 speed Road Bike, with Front Chain Rings (30t, 39t, 49t) and Rear 10 speed that has a 25t-12t cassette. A 30 speed bike does not really have 30 speeds because several of those possible combinations of front and back cogs will probably result in the same number of back wheel revolutions per pedal. My bike is fine for all around riding, but not for racing. If you have to use the granny gear during a race you might as well walk fast because you'll be going about the same speed, so removing that front low gear will force you to keep a faster pace or speed.

Road Crank-Arms now range from 165 to 180mm long. Femur length and foot size, both of which are primary lever arms in a pedal stroke. If you do end up changing crank-arm lengths, it will change your gearing as well. How hard or easy an individual gear feels depends on three things: the combination of chain-ring and cog size that actually produces it, the wheel size it rolls on, and the crank length that turns it. Adjusting saddle height to account for the longer or shorter cranks may be all you need to do. A lot of triathletes who go to shorter cranks do it in part because it opens up the hip angle at the top of the pedal stroke as the seat rises. Gain Ratios

The cold in the air changes the pressure of the air. So every time you pump them when it is warmer outside, once the temperature drops the pressure of the air itself in the tires decreases. Most tires are inflated with air, although some dealers are now using nitrogen because the nitrogen molecules are larger than oxygen molecules. The tire doesn't 'lose' air, the air just becomes denser, because the air molecules are cooler. So the denser air means it doesn't take as much space in the tires therefore the pressure is lower.


I Keep Breaking Spokes
32 spokes make a good durable wheel, but if you're large and ride off-road, then 36 spokes is better. And you might want to consider double butted spokes. The spokes are thinner in the middle section which allows them to stretch a bit when the wheel is hit. This helps to prevent the elbow near the spokes head from flexing (which leads to fatigue and spoke breakage), and also takes the stress away from the rim wall near the nipples. Heavy riders should look up the manufacturers maximum spoke tension spec for the rim and dial that in with a good tensiometer.

Electric Bike Pros: Increased Distances, Less Time to Travel and Less Human Energy Needed.
Cons: More Expensive, More Maintenance, More Weight, More Things that can go wrong and More Risk of an accident because of longer travel distances and higher speeds. But I will still buy an electric bike in around 20 years when I'm around 80 years old. And the e-bike will be a Step-Thru frame style, and also be pedal assist, just incase the battery dies, or if I feel like pedaling myself. But if I move to a place where food and necessities are 10 miles away or more, then I will most likely buy an e-bike before I'm 80. But for now I live in a city where a lot of things are nearby. So it's not so bad to pedal myself. And I also get some exercise, which is always a plus, except for the car pollution, which totally kills a lot of the benefits of riding a bike and other things. So electric cars will save the day, for everyone and everything. Electric Bike Review

Shifting Gears problem on my bicycle in cold weather. You might be right about the thicker grease. About the only effective way to get it out (aside from a complete teardown/rebuild) is with a thinner/lighter hydrocarbon-based solvent. WD-40 comes to mind as a quick fix. I'd just shoot some in and see what happens. If you want, you could then follow that up with a lighter lube to keep everything running smooth. temperature-related shifting problems like this as well. I can only guess that it is the caused by the difference in expansion of the cables and frame in response to the cold. I suggest you adjust your shifting cables outside in the cold, where you normally will ride it. Otherwise you might have to adjust them whenever there is significant temperature changes. freezing up and preventing cable release. Last winter I replaced the shifter cable housing presuming moisture or other foreign substance was freezing up and preventing cable release. (I could force the shift to higher gear but it would not release back to lower gear during sub freezing temperatures) It did not fix the problem --leaving me to presume either the shifter or the internal hub shifting mechanisms were at fault. Either way I have to just deal with it. There are lots of threads detailing the flush/relube procedure for shifters that fail to shift properly in cold weather. It's a pretty easy process- good luck! think trigger shifters rely on the cable pull provided by the derailleur spring to shift in one direction so anything you can do to increase that pulling force should help. The factory grease in the shifters tends to dry up a bit and get stiff as time passes,
and the problem is exacerbated in cold weather. The easiest solution is to remove the plastic cover, squirt some light oil in and around the ratchet and pawls (chain lube is just fine) and then shift up and down a few times to work it in. That'll thin out the grease and usually solve your problem. With three of my bikes, it's been easily fixed by flushing and regreasing with lighter lube. One was an old Trek with early RSX shifters, one was a mid-90s Fisher with trigger shifters, and one was similar to the Trek's shifters- early 600 parts or something along those lines. My method was to flush the shifters with a good bit of degreaser, then flush that out as well as possible with a light lube (something you can spray or drip in rather than a grease), and then to reapply light lube a day or two later. The symptoms are what everybody here is describing: it'll shift fine in room temperatures, but the pawls won't catch properly once the temperature drops. Sometimes careful, slow movement of the shift lever will allow it to catch, indicating that the small springs are still trying to push the pawls into place but can't do so as quickly as when the grease is warmer and less viscous. .
 

I ride my bike, I roller skate, don't drive no car, don't go too fast, but I go pretty far..Melanie Safka

It's not just riding a bike, It's being healthy, it's saving resources, it's saving the environment, and it's saving lives. Cars with combustion engines are outdate, obsolete and an insult to our intelligence. You can't even begin to justify using all those resources, time and people just to build these over priced inefficient machines that need constant maintenance, and on top of that when you use them you pollute the earth. You're basically saying to the world "F*ck you I'm an idiot and I don't care", well maybe not that bad because most people just don't know any better and some people are just too afraid to face the truth. Yes there are a small number of people who are actually making a difference using these ignorant modes of transportation, but that's less then 10 percent, so there's a lot of room for improvement.   Gas Prices

People who have more protective gear take more risks. People who drive cars have more head injuries. People have more head injuries falling at home then bikers.
