E‑Bike Hill Climb Calculator
E‑Bike Hill Climb Calculator
Estimate required motor power to climb a slope, or calculate the maximum sustained incline for a given motor power.
Typical: 0.003–0.01 (road to off‑road)
Typical upright e-bike: 0.5–0.8
Required motor power: — W
Breakdown: —
Maximum sustainable grade: — %
Note: This is an estimate. For short bursts (e.g. sprints) motors can exceed continuous power.
Advanced: formula & code notes
Power components used:
- Gravity (climb): m * g * v * sin(theta)
- Rolling resistance: C_rr * m * g * v * cos(theta)
- Aero drag: 0.5 * rho * CdA * v^3
