Best BMX Crank Length Calculator | Find Your Size

A tool designed to determine the optimal crank arm length for BMX riders considers factors such as rider height, inseam, riding style, and bike size. For instance, a taller rider with a longer inseam might benefit from longer cranks, while a street rider might prefer shorter cranks for increased ground clearance. These tools often provide recommended lengths based on inputted data and can be presented as online calculators, charts, or formulas.

Proper crank arm length is crucial for efficient power transfer and comfortable riding. Choosing an appropriate length can improve pedaling efficiency, reduce the risk of knee injuries, and optimize bike control. Historically, crank length selection was based on experience and anecdotal evidence, but the availability of analytical tools offers a more precise and data-driven approach. This allows riders to fine-tune their setup for improved performance and comfort.

8+ Exceptional Kelley Crank Easels from the Leading Brands

A Kelley crank easel is a type of easel that uses a crank to raise and lower the canvas. It is a versatile easel that can be used for a variety of painting techniques, from oil painting to watercolor. Kelley crank easels are also relatively portable, making them a good choice for plein air painters.

One of the main benefits of a Kelley crank easel is its ability to hold the canvas at a variety of angles. This makes it ideal for painting subjects that are located at different heights. The crank also makes it easy to adjust the height of the canvas, which can be helpful when working on large paintings.

6+ Best Crank to Wheel HP Calculators (2024)

A drivetrain power loss calculator estimates the horsepower delivered to the wheels of a vehicle, accounting for losses due to friction and inefficiencies in components like the transmission, differential, and driveshaft. This “wheel horsepower” figure represents the actual power propelling the vehicle, which is always lower than the engine’s output, or “crank horsepower,” measured directly at the crankshaft. For instance, if an engine produces 200 crank horsepower but only 160 horsepower reaches the wheels, the drivetrain loss is 40 horsepower or 20%.

Understanding the difference between crank and wheel horsepower is crucial for accurate performance assessment. Wheel horsepower provides a more realistic measure of a vehicle’s usable power, influencing acceleration, top speed, and overall driving dynamics. Historically, measuring wheel horsepower required specialized equipment called a chassis dynamometer. However, advancements in technology allow for estimation through calculators using crank horsepower and estimated drivetrain loss percentages based on vehicle type and drivetrain components.
