How much does the Tern Vektron P5i cost in Australia?
The Tern Vektron P5i is listed at $6,995 (ride-away). eBikeFinder checks pricing against manufacturer and distributor information, and prices can change with sales and stock. This price was last checked on 9 Oct 2026.
Is the Tern Vektron P5i road legal in Australia?
Yes. The Tern Vektron P5i is a 250W pedal-assist e-bike that stops assisting at 25 km/h, which meets the road-legal e-bike standard in every Australian state. Compliance is asserted by the brand rather than independently verified, so confirm the current spec with the seller.
What is the range of the Tern Vektron P5i?
The Tern Vektron P5i has a claimed range of 55 to 120 km from its 545Wh battery. Real-world range is usually lower than the claim, since it depends on assist level, rider weight, terrain and wind.
What motor does the Tern Vektron P5i have?
The Tern Vektron P5i uses a Bosch Performance Line motor, in a mid-drive position, producing 75Nm of torque. Mid-drive motors climb hills better because they work through the bike's gears.
How much does the Tern Vektron P5i weigh?
The Tern Vektron P5i weighs about 23.6 kg. That matters if you need to lift it onto a car rack, carry it up stairs, or store it, since e-bikes are heavier than regular bikes because of the motor and battery.
Who sells and backs the Tern Vektron P5i in Australia?
The Tern range is distributed in Australia by 99 Bikes and independent dealers. It comes with a 2 years frame, 2 years motor and battery warranty. Buying from a brand with real Australian support matters most when something needs a warranty claim or a service.
