what size e-bike battery do I need
Choosing the right battery size prevents overpaying while ensuring reliability.
Step 1: Measure Your Typical Distance
Most UK riders travel:
- 5–10 miles per trip
- 20–30 miles per week
Step 2: Factor in Terrain
Hills dramatically increase energy use.
Step 3: Consider Usage Type
- Short commutes → smaller batteries
- Leisure touring → mid-range batteries
- Long rides / cargo → larger batteries
Oversizing vs Undersizing
A slightly larger battery offers flexibility but adds weight and cost.
The Bottom Line
Battery size should match real usage, not occasional extremes.
