Stationary Bicycle, Generator, Cooling Wind

post HFA 26 show edit:
1. A load variation knob control is available. The show bike was set up for low load physical therapy rehab weak user condition, which was my error for an athletic show HFA.
( Said knob changes the amount of fan power by reducing the electricity delivered to the fan when driven by a larger high gear fan reduction drive pulley with some increase in radio audio noise.)
2. The show bike had the pedals in the crank arm low length pedal arm position,
-the pedal arm has additional positions for longer typical pedal arm radius of rotation.
-(and two types of threaded holes to accommodate all types of pedals from real bikes and exercise bikes)
-the short pedal arm option has 3 use cases:
a. less body motion to interfere with writing at the desk, using phone etc.
b. easier to achieve higher voltage in PR rehab weak user situations.
c. There is a bike endurance champion who used such short crank arms.
3. Constant Future Service and Upgrade policy, My career building out and managing Physical Therapy, Orthopedic Offices and Residential Apartments, means quick on site repairs and upgrades are the rule. Product Liability risk is reduced for you the user and RetroProto LLC with a Lease type transaction. The whole product design is to reduce sweat, grief, wasted time and suffering of the exercise user, the gym operator, and RetroProto LLC.
4.All known seat types and adjustments exist. Banana, conventional, ledge, sling, rowing
RetroProto's stationary bike has Air Cooling like a real Bike, and thus has 10 times the exercise duration of conventional stationary bikes.
Your facility will have reduced need for air conditioning

"Figure 2.4 shows that athlete cyclists can exert greater than 400 W (0.54 hp) for periods of up to 1 h. A common range of endurance when pedaling ergometers at 0.5 hp (373 W) is 5– 15 min (Whitt 1973), which again demonstrates vividly the value of flowing air in prolonging the tolerable period of hard work.

"Bicycling generates a relative airflow of such magnitude that it bears little resemblance to the drafts produced by the small electric fans often used for cooling people pedaling ergometers,"

Sweating is Overheating

Sweat is Bad

1. Dehydration

2. Ineffective Cooling
