Disclaimer: I believe the things I say are true, but I don't necessarily have scientific evidence to back everything up. Keep in mind that I am older than you.

  1. Bicycling requires stamina. Think about it. Bicycling is all uphill (unless you live in the plains of the Mid-West). It may take you a half hour to climb a hill, but it will only take a few minutes on your descent. It takes time and effort (i.e. training) to build stamina. To build stamina, I would do the 2 miles a day several times a week until it started to feel comfortable. Then I'd go to 3 miles, etc. After a while, your stamina will increase.

  2. Another thing to consider is warming up. Professional cyclists never just jump on a bike and race. Before any race, they either ride a stationary trainer or go for a warm up ride. This allows their bodies to prepare for the extra effort they're demanding from their bodies. When I ride, the first few miles are frequently the most difficult. I need my blood vessels to dilate in order to increase blood flow while maintaining increased respiration for several hours. Sometimes, it takes 2 or 3 or 4 miles until my body feels ready to hit its cadence and ride all day. It's possible that your body needs a little more than the 2 miles to warm up. That may be why you feel tired. You may want to try pushing through it to see if you feel better and ensuring that your body is "warm".

  3. It's not the bicycle; it's the rider (Part 1) - The bike you have should be fine for the riding you are doing now. Take it to a reputable bike shop and have it tuned up and save your money for your new bike once you see what kind of riding is right for you. I still ride my 1969 Peugeot UO-8. By today's standards, it's old and clunky and several pounds heavier than anything available today, but I absolutely love it.

  4. It's not the bicycle; it's the rider (Part 2) - I'll give you an example using Peter Sagan. Peter is one of the world's best professional bicyclists. His exploits are legendary and he is a true bicycling rock star. Three time World Road Racing Champion, six time Green Jersey winner in The Tour de France, and a string of wins in other major races as long as your arm.

When Peter was a teenager, he had to borrow his sister's "supermarket" bike in order to compete in the Slovak Cup Race. While all of the other riders had their bicycles tuned to the hilt and donned their fancy aerodynamic skin suits, Peter showed up in a tee shirt and sneakers riding his sister's bike with poor gearing and poor brakes. He won and has never looked back. Now, he rides a Specialized S-Works Venge with a starting price $12,500.00. I don't really care what he's riding, if he's in a race, I'm betting on him.

Bicycling is a wonderful activity and sport. Regardless of whether you are doing 2 mile rides or several day tours of hundreds of miles, I hope you're having fun. That's really what its all about!

29" wheels are a little bigger than 700c. Generally they have more cyclocross or mountain tread. The idea is that they roll over more easily

Yeah I checked and the rear would be a problem, 24 in tire is to close to the frame down by the Bicycle Crankset

Bigger wheels and slick tires make it easier to go farther, more easily. So if you put 26 or even 29 inch tires it'd help - a little.

Really, though, the biggest thing is just ride more. 2 months isn't that long. Are you riding really hard or more moderate? And how much experience riding do you have?

One thing you might not know is to keep a constant cadence is around 90rpm. That's the range your legs operate most efficiently at. If you have the gears too hard you'll get tired more quickly.

Yes I've read about cadence and mine is 60, I'm working on improvement.

[–] clamhurt_legbeard 0 points 0 points (+0|-0) ago 

60 is good.

If you want more rpm, just shift down!

Upgrading the bike will not improve your health. Try a different gear either peddling faster but not as hard or harder but not as fast.

A good road bike cost a lot and I'm a pensioner so I was thinking upgrading what I have and ride it and save for better.

If you are doing this for fitness and health how far or fast you go doesn't matter. What matters is that you push and get farther over time. Upgrading will make it easier but you gain no health benefits and have spent money.

What kind of terrain are you riding on?

[–] aileron_ron [S] 0 points 0 points (+0|-0) ago 

Just streets.
