Who is this for?
Best suited to
Commuters who want a mid-drive step-up from the rear-hub Level 3, with strong hill torque, big range and Aventon's connected anti-theft hardware built in.
Consider alternatives if
You live in NSW, where BikesOnline does not ship it and NSW sale approval is not yet verified, or you want to spend less and the rear hub Level 3 covers your commute.
Standout strength
A 250W Ultro S mid-drive with up to 100Nm of torque, an 800Wh battery and electronic AutoShift, plus GPS and 4G tracking, geofencing and an integrated wheel lock.
Check before buying: Check stock (it was out of stock in every size on 8 October 2026), confirm delivery to your state, choose between the step-over Level 4 ADV and the step-through Level 4 ADV ST, and ask BikesOnline for the EN 15194 paperwork and the battery's true capacity before you pay.
