Quick answers

Is the Merkx S600 Pro legal in Australia?

Not as a road-legal e-bike: its motor is listed as assisting to 50 km/h (the limit is 25 km/h). On public roads and paths it would be treated as an illegal device or an electric motorcycle needing registration, and in Queensland police can seize illegal e-bikes. It can be ridden on private property.

What is the real-world range of the Merkx S600 Pro?

EbikeMate estimates about 54–80 km per charge from its 1200 Wh battery, for an 80 kg rider on rolling terrain in a middle assist level at about 20 km/h. Hills, headwinds, cold weather and higher assist cut range.

How big is the Merkx S600 Pro battery?

1200 Wh. Use only the original or a maker-approved battery and charger.

What motor does the Merkx S600 Pro have?

A front + rear geared hub (AWD) motor with 160 Nm of torque.

How much does the Merkx S600 Pro cost in Australia?

Its recommended retail price is listed at $2,599.

How heavy is the Merkx S600 Pro?

About 40 kg, as listed by the maker (usually including the battery).

Has the Merkx S600 Pro been recalled?

No recall for the Merkx S600 Pro is listed in the EbikeMate Recall Centre, which tracks Product Safety Australia and maker notices. Registered owners are emailed if one is published.

Australian rules

Government informationEbikeMate editorial guidance

Across Australia a pedal-assisted e-bike (EN 15194) may have up to 250 W continuous rated power, with assistance cutting out by 25 km/h. Throttle rules differ by state. What the maker states for this model:

Rated power: not stated by the source
Assistance to: 50 km/h — above 25 km/h, so it is not a pedal-assisted e-bike for public roads and paths
Throttle: not stated

Real-world range

54–80 km

Our estimate for an 80 kg rider on rolling terrain in medium assist at about 20 km/h, with a healthy battery. Hills, wind, cold, high assist and speed cut it a lot.

Work out my range

Battery and charger

Use the maker’s own replacement battery, or one the maker or a specialist confirms is approved for this motor system. Voltage, connector and battery-management system all have to match.
Use the original charger, or one the maker approves for this battery. Never use a charger with a different output, even if the plug fits.
Check the battery’s own label (Wh, V and serial) matches what the seller says.
Damaged, swollen, hot or smelly batteries: stop using them, keep them outside away from anything that can burn, and take them to a battery drop-off — never household bins.

Check my battery and charger

Servicing

A first check after the first few hundred kilometres — new cables stretch and bolts settle.
Chain: clean and lube regularly and measure wear — e-bikes wear chains and cassettes faster than regular bikes.
Brakes: check pads and cable tension often — the extra weight and speed wear them faster.
Hub motor: check the axle nuts or thru-axle and torque arms, and that the motor cable isn’t pinched or rubbing.
Battery: keep it between 20% and 80% for daily use, store it at about half charge, and keep it out of hot cars.

Buying a used one

Run the serial through the free EbikeMate buyer check — theft status, recalls and ownership on record.
Find the frame serial yourself (usually under the bottom bracket) and check it matches the seller’s papers.
Ask how old the battery is and check it holds charge on a test ride up a hill.
Look for signs of derestriction: tuning dongles, unusual wiring, or a top assisted speed above 25 km/h on the display.
Ask for the receipt, the original charger and the key for the battery lock.
