“How Far Will It Go?” — The Most Important E-Bike Question
Range anxiety is real. Nobody wants to run out of battery halfway to work. The problem is that e-bike range claims are routinely overstated — sometimes by 40–50%. This guide gives you a realistic picture of what to expect on Australian roads, not in a manufacturer’s test lab.
What the Numbers Actually Mean
Most e-bikes advertise range based on ideal conditions: flat ground, light assist, 70kg rider, 20°C temperature. Real-world Australian commuting involves hills, heat, heavier riders, and higher assist levels. Here’s what to expect in practice:
| Battery Size | Advertised Range | Real-World Range (AU) | Best For |
|---|---|---|---|
| 250–360 Wh | 40–60 km | 25–40 km | Short flat commutes under 12km |
| 400–500 Wh | 60–90 km | 45–65 km | Typical city commutes 15–25km |
| 600–750 Wh | 90–130 km | 65–90 km | Long commutes, hilly terrain, touring |
| 900 Wh+ | 120–180 km | 85–130 km | Heavy use, cargo bikes, adventures |
The 5 Factors That Kill Your Range
1. Hills
Sydney, Melbourne, and Brisbane are not flat cities. A hilly commute can cut your range by 30–40% compared to flat riding. If your route has significant climbs, size your battery up one category from what you think you need.
2. Assist Level
Using maximum assist burns battery 3–4x faster than eco mode. Most commuters find mid-level assist (level 2–3 of 5) the best compromise between effort and range. Save high assist for hills.
3. Rider Weight
The motor works harder for heavier riders. A 90kg rider will see roughly 15–20% less range than a 70kg rider on the same bike.
4. Tyre Pressure
Underinflated tyres create more rolling resistance and drain the battery faster. Check tyre pressure weekly — it takes 30 seconds and can add kilometres to every ride.
5. Temperature
Lithium-ion batteries perform poorly in cold weather. An Australian winter morning (10–15°C) can reduce effective battery capacity by 10–15%. Not a massive issue in most Australian cities, but worth knowing.
How to Maximise Your Range
- Start in eco mode and only bump up assist for hills
- Keep tyres pumped to the recommended pressure
- Pedal more, especially on flat sections
- Store the bike indoors in winter so the battery starts warm
- Charge after every ride rather than running the battery flat
What Battery Size Do You Need?
A simple rule: take your one-way commute distance, double it (for the return), add 20% buffer, and that’s your minimum range target. For a 15km each-way commute in Sydney with moderate hills, you want a bike with at least 45km real-world range — meaning a 500Wh battery is your minimum.
Don’t Let Range Anxiety Hold You Back
The right battery size for your commute makes range anxiety irrelevant. Most quality e-bikes with a 500Wh+ battery handle the typical Australian daily commute with charge to spare.
