The Aventon Aventure 3
Electric fat bikes trade efficiency for grip. Tyres around 4in wide spread the load, so a fat tyre electric bike floats over sand, snow and loose gravel rather than cutting into it. The two here are $1,899 and $1,999, weigh 31.8 and 34.5 kg, and publish 89 and 105 km. Those are the heaviest non-cargo bikes we sell, and the weight is the whole trade. This one runs 36V 750W hub (1440W boost), paired with a 733 Wh battery for up to 105 km of real-world range.
Specs verified against aventon.com. TOP ASSIST CORRECTED 28 to 20: the standard Aventure 3 is Class 2 (20 mph); the separate Aventure 3 HS is the 28 mph Class 3 model. Battery 36V 20Ah 733Wh LG 21700 cells (UL 2271). Weight 76 lb / 34.5 kg; 400 lb total limit. Sensor Switch lets the rider pick torque or cadence sensing. Aventon BC280 display; 36V 33A controller; left-hand throttle; 4in fat tyres; range up to 65 mi.

The Aventon Aventure 3 is a fat tire ebike for riders who stop planning their route around the surface. Four-inch tyres, 80 Nm of torque and a 733 Wh battery, at $1,999 ride-away. Gravel, broken pavement, wet grass, sand and packed snow all stop being a decision.
It replaces the Aventure 2, and the interesting change is not the motor. Both run a 750 W rear hub. What Aventon added is a switch that changes how the bike reads your legs, and that matters more than any headline wattage.
The Sensor Switch is the actual upgrade
Most e-bikes pick your assist style for you. A cadence sensor watches whether the pedals are turning and feeds in power accordingly. A torque sensor measures how hard you are pushing and matches it. The Aventure 3 lets you choose, from the bar, whenever you like.
That matters because the two feel nothing alike. Cadence assist surges. You turn the pedals and the bike shoves. It is useful when you are tired, carrying shopping, or pulling away uphill from a standing start. Torque assist feels like your own legs on a very good day. It is smoother, it flatters your riding, and it draws less power for the same distance.
Nine times out of ten we would tell someone to buy the torque-sensing bike and never look back. Here you get both, so the honest advice changes: ride it in torque mode, and keep cadence for the days your legs have nothing left.
Range: the number, and the number you will actually see
Aventon quotes up to 105 km on a charge. That figure is real, and it is a lab figure. It assumes a 75 kg rider, low assist, flat ground and no wind. Ride like that and you will get close to it.
Plan around 55 to 75 km for normal riding on mixed ground at middling assist. Fat tyres cost you range because there is simply more rubber pressed into the road. Push the throttle a lot and the number drops again. That is not a fault of this bike, it is physics, and any brand quoting a single number without conditions is selling you the lab.
For most riders the practical question is simpler than any of that. A 733 Wh pack on a 20 km round-trip commute is three or four days of riding between charges. Most people never see the bottom of it.
It weighs 34.5 kg. Plan for that before you buy
This is the specification nobody puts in the headline. The Aventure 3 weighs 76 lb, or 34.5 kg. That is heavier than most city e-bikes and close to cargo-bike territory.
On the road it is a non-issue. The weight sits low, the tyres soak up the surface, and the motor does not care. Off the road it is the whole story. Carrying this up a flight of stairs to a first-floor flat is a genuinely bad time, every day, forever. Lifting it onto a boot-mounted car rack needs two people or a very good technique.
Rule of thumb: if the bike lives in a garage, a shed or a ground-floor hallway, the weight will never bother you. If it has to go up stairs, buy something else and thank us later.
Step-through or step-over, and how to pick
The Aventure 3 comes in two frames at the same price. The step-over has the traditional top tube. The step-through drops it, so you swing a leg through the middle rather than over the back.
Pick the step-through if you have any hip or knee restriction, if you ride in work clothes, or if you stop and start constantly in traffic. On a 34.5 kg bike, not having to lift your leg over the saddle is worth more than it sounds.
Pick the step-over if you want the stiffer frame and you ride longer distances. Sizing splits by height rather than frame style: the regular fits roughly 5'3" to 5'10", the large 5'10" to 6'4".
Is this the right bike?
Buy it if
- Riders whose route mixes tarmac, gravel, tracks and the occasional bit of sand or snow
- Anyone who wants a throttle as well as pedal assist, for pulling away or arriving unsweaty
- Riders between 5'3" and 6'4", with a total load of up to 400 lb including luggage
- People who want to try both torque and cadence assist without buying two bikes
Buy something else if
- Anyone carrying a bike up stairs. At 34.5 kg this is the wrong bike for a first-floor flat, and no feature on the spec sheet changes that.
- Riders who want 28 mph assist. The standard Aventure 3 is a Class 2 bike capped at 20 mph. The 28 mph version is the separate Aventure 3 HS, so check which one you are ordering.
- Commuters who only ever ride smooth tarmac. Fat tyres cost you rolling efficiency and range for grip you are not using. A city bike will be faster, lighter and cheaper.
- Anyone who needs to lift the bike onto a high car rack alone.

Straight answers
Does the Aventon Aventure 3 have a throttle?
Yes. It has a left-hand handlebar-mounted throttle alongside the pedal assist, which is what makes it a Class 2 ebike. The throttle works up to 20 mph.
How fast does the Aventon Aventure 3 go?
Assist and throttle both cut out at 20 mph, because the standard model is Class 2. If you want 28 mph you need the Aventure 3 HS, which is a different bike. Assist limits vary by country, so check what is legal where you ride.
What is the difference between the Aventure 2 and the Aventure 3?
Both use a 750 W rear hub motor. The Aventure 3 adds the Sensor Switch, which lets you swap between torque and cadence sensing from the handlebar, plus a 733 Wh battery using LG 21700 cells and the BC280 display.
How long does the battery last?
The 733 Wh pack is good for roughly 800 to 1,000 full charge cycles before it drops to 80% of its rated capacity, which is three to five years of normal riding. Keep it between 20% and 80% for long storage and it will get there comfortably.
What's the range on the Aventure 3?
105 km on a single charge under normal conditions. Real-world range varies with rider weight, terrain and assist level.
Is the Aventon Aventure 3 in stock?
Current availability: In Stock.
What warranty does it come with?
