Quick answers

Is the Polygon Tambora AE-N legal in Australia?

The specs we have don’t state its rated power or assist speed, so check the bike itself: a legal pedal-assist e-bike has at most 250 W rated power (shown on the motor or frame label) and stops assisting at 25 km/h. In Queensland it also needs an EN 15194 (or Legacy EPAC) compliance label to be ridden in public from 1 March 2027 — check the frame for the sticker.

What is the real-world range of the Polygon Tambora AE-N?

EbikeMate estimates about 25–37 km per charge from its 400 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 Polygon Tambora AE-N battery?

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

What motor does the Polygon Tambora AE-N have?

A Bosch Performance Line SX mid-drive motor with 55 Nm of torque.

Has the Polygon Tambora AE-N been recalled?

No recall for the Polygon Tambora AE-N is listed in the EbikeMate Recall Centre, which tracks Product Safety Australia and maker notices. Registered owners are emailed if one is published.

Real-world range

25–37 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.

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.
  • Mid-drive: ask the shop to read the motor’s error log and update firmware with the maker’s diagnostic tool at each service.
  • Battery: keep it between 20% and 80% for daily use, store it at about half charge, and keep it out of hot cars.

Find a shop near you.

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 for a recent diagnostic printout — most mid-drive systems record battery health, charge cycles and motor hours.
  • 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.
