E-Bike Range Calculator + Playground (April 2026 Update)

Two e-bike tools in one project: a route-aware range calculator for real ride planning and a real-time playground for simulation, tuning, and testing.

📖Project Details

E-Bike Range Calculator Project (April 2026)

This project now has two connected apps, each built for a different stage of ride planning and bike setup:

The goal is simple: make battery decisions obvious before the ride starts, then let you test setup behavior in a live simulator.

Two apps, one workflow

1) Main app — route-aware range planning

Use the main app when you want to answer practical questions like:

  • Can I finish this route on one charge?
  • How much does wind and climbing change my expected range?
  • Where should I recharge on longer rides?

What it does best:

  • GPX-based route analysis
  • Weather-aware and elevation-aware energy estimates
  • Battery consumption breakdown and charging-stop planning
  • Browser-first workflow with private, local planning

2) Playground — real-time simulation and tuning

Use the playground when you want to experiment:

  • How does changing motor/controller/battery setup affect ride behavior?
  • What happens to dynamics under different assist, throttle, slope, and load?
  • How does a specific scenario feel before trying it outside?

What it does best:

  • Real-time simulation engine
  • Component-level setup experimentation
  • Scenario-driven testing and iteration
  • Fast feedback loop for advanced users

How they work together

The main app helps you plan the actual ride outcome.
The playground helps you understand and tune the machine behavior behind that outcome.

If you're planning a trip, start with the calculator.
If you're comparing setups or exploring performance tradeoffs, move to the playground.
