Aventon Aventure 3 Step-Through
The easy-mount Aventure 3 — the same 750W (1440W boost) fat-tire drivetrain, 733Wh battery and ACU smarts as the standard bike, with a dropped top tube for a low, confident stand-over.

A lockout suspension fork plus a 50mm suspension seatpost take the sting out of rough ground.

750W Boost Hub
750W nom · 1440W boost · 80 Nm
Boost To 1440W
The 750W hub peaks at 1440W in Boost Mode with 80Nm — strong launches and confident climbs on loose terrain.
Torque-Sensor Ride
A torque sensor meters assist to your effort so the power feels natural, not switch-like.
Up To 65 Miles
A 36V 20Ah 733Wh LG-cell battery is good for up to 65 miles and refills in about 5 hours.
Stops, Safety & Smarts
ACU · hydraulic disc
Hydraulic Disc Brakes
Tektro HD-E3520 hydraulic discs with 180mm rotors handle the heavier fat-tire chassis.
ACU Smart Bike
GPS, 4G, geofencing, an integrated rear-wheel lock and Apple Watch support come built in.
Cruise & Boost
Cruise control and Boost Mode make longer rides and steep pitches easier to manage.
The Cockpit
A Bright, Connected Cockpit
BC280 Display + Torque Sensor + ACU Smart Features
The Aventure 3 steps up to Aventon's larger BC280 display, keeping speed, battery, range and assist clear in daylight, with a torque/cadence sensor switch for the ride feel you prefer.
Full ACU connectivity — GPS, 4G, geofencing, rear-wheel lock and Apple Watch integration — makes it a genuinely smart adventure bike.

The step-through Aventure 3 shares the standard bike's fat-tire drivetrain but drops the top tube for a low, easy stand-over — a better fit for riders about 4'11" to 6'1" or anyone who wants to hop on and off easily. It weighs 77 lbs with the same 400 lb payload.

The Bike Cave Verdict
Ben's Take
The step-through Aventure 3 is the same capable fat bike with the barrier taken away. You still get the 750W hub that boosts to 1440W with 80Nm, the torque sensor, 26 × 4.0 tires, the 80mm fork and up to 65 miles of range — but a dropped top tube makes mounting, stopping in traffic and loading up far easier. For shorter riders, anyone with mobility considerations, or riders who just prefer a low step-over, this is the Aventure 3 to buy. I haven't ridden it on camera yet, but at $1,799 it's the same strong all-rounder value. Full review to come.
