1. What is Ebike Frame Size?

The ebike frame size is a crucial measurement that determines how well the bike will fit your body. A properly sized frame ensures comfortable riding, efficient pedaling, and better control of the bicycle.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• \( Inseam \) — Your leg length measured from crotch to floor (cm)
• \( 0.66 \) — Standard multiplier for ebike frame sizing

Explanation: This formula provides a good starting point for most riders, though individual preferences may vary based on riding style and flexibility.

3. Importance of Proper Frame Size

Details: A correctly sized frame prevents discomfort, reduces injury risk, and improves riding efficiency. Too large a frame can be hard to control, while too small may cause cramped riding position.

4. Using the Calculator

Tips: Measure your inseam accurately by standing barefoot against a wall with a book between your legs (simulating a bike seat). Measure from the top of the book to the floor.

5. Frequently Asked Questions (FAQ)

Q1: Is this formula suitable for all ebike types?
A: This works well for standard ebikes. Mountain bikes may need slightly smaller frames (0.63-0.65 multiplier), while road bikes might use 0.67.

Q2: How does frame size affect comfort?
A: Proper size ensures optimal leg extension, back angle, and reach to handlebars - all critical for comfort.

Q3: Should I round up or down?
A: If between sizes, consider your flexibility and riding style. More aggressive riders may prefer smaller frames.

Q4: Does this work for step-through frames?
A: Step-through frames use different sizing. Consult manufacturer's size charts for these models.

Q5: What if my calculated size isn't available?
A: Choose the closest size and adjust with seat height and stem length. Test ride if possible.
