The simplest answer is balance.
It isn't energy - you expend the same whether you're pedalling or walking to achieve the difference in altitude.
However, the cadence (rate at which you spin the pedals), and the gearing between your foot speed and the (rear) wheel speed is a factor in the how fast the wheels move ... and therefore in how good a gyroscope you have. Faster feet (and faster wheel speed) means better balance.
Climbing a hill, you trade off mechanical advantage for foot speed, at the expense of wheel speed. The amount of strength expended to keep the bike upright (by tweaking with your upper body) increases after a certain foot/wheel combination is achieved. Thus it becomes "harder" to do.
The other point of balance has been referred to earlier by another answerer; if the center of gravity (of the system, which includes both the rider and the bike) advances too far forward, there's a loss of balance. The same occurs if it moves too far rearward. At intermediate points, it requires more concentration and percieved effort to keep everything "rubber side down" ... thus it appears harder to accomplish some maneuvers on the bike.

try some weekend rides first. And do as others have stated. Tuesday Thursday, Then Tuesday, Thursday Friday for a pair of weeks. Then throw in a Monday. final, upload the mid week Wednesday to the equation. Scope your path. are able to throw in a short decrease or 2. purchase high quality kit. Fity kms an afternoon will root much low priced kit below a huge guy without delay and price you greater to swap than a high quality holiday first up. And Carlos, i think of he will have the potential to regulate a yet greater suitable than 20kph! yet . . . your suitable, it relatively is going to take a whilst to get the activity executed initially and a mountain motorcycle is relatively no longer the perfect device for the activity. The furtherest distance everyone in the international has ever ridden in one hour is only below 50km. An hour each and every way would be a real looking objective time to start up with, which remains a heck of the thank you to awaken. Dude, pass to a bike shop, communicate with actual human beings, try holiday a bike or 2. Edit: i'm getting perplexed right here, 25km to artwork, 25 km to residing house, thats 50 km around holiday yeah ? if so then you definately will comfortably do 25kms in one hour, in all threat plenty much less. you will desire to be cranking alongside between 25 to 30kph without too plenty attempt. No way in hell it takes 2 hours to holiday 25 km !

riding a bike on flat land your center of gravity for you and the bike is at the pedals....when you go down hill that center of gravity slides forward and the steeper the hill, the more it moves forward. once it reaches the axle of the front wheel...your body weight will take you over the handle bars.
same principle if going up a hill.....steeper it is the center of gravity slides back and once it hits axle of back tire, backwards you fall off.
when walking....your ears and balance mechanism is like a ball foating in a bowl of water.....as you change from flat to hills....that water moves around but the ball remains on top of it all....in turn...keeping you in balance. plus your legs take up the extra strain in muscles and you'll either lean forward or back depening on how steep it is.

When you are riding the bike you are controlling more weight ina differant angle and it is harder to controll . where as if you are walking with it it is much easier to control . you can stop quicker.

because your using the pedals, unlike walking, your feet is on the ground and you get grip
