Aventon Aventure M review

Should you buy one?

Buy the Aventure M if you want a fat tire bike for gravel, dirt and rocky trails and you’d rather let the bike pick the gear and assist level. Its Auto mode and AutoShift are the biggest improvement I’ve seen from Aventon in about 10 years of testing their bikes. Going back to the Sinch and the Level, this is the one I’d buy for a go-anywhere bike.

Skip it if you want a throttle or a bike you can lift easily. It’s Class 1, so it has no throttle out of the box, and Aventon lists it at 73 lbs.

The deciding factors: throttle or no throttle, and how much you’ll ride rough ground. If you need a throttle, the Aventure 3 is the better fit. If you want the bike to handle the shifting and assist on its own, the Aventure M is the one.

Quick specs

From Aventon’s Aventure M page, checked Oct 22, 2026.

Aventon lists IPX6 for the bike and IP67 for the motor. The throttle is sold separately.

Who it’s for

• Riders new to mountain biking who find shifting frustrating. When you don’t know which gear you should be in, Auto mode makes that decision for you.
• Experienced cyclists who want a fat tire bike that pedals like a real bike. If you already ride mountain bikes, this is the Aventon to try.
• Commuters who also ride trails. The rack, fenders, integrated lights and turn signals cover the commute, and the fat tires and suspension handle the dirt.
• Riders from about 5’3” up. Aventon sells a Regular for 5’3” to 5’10” and a Large for 5’10” to 6’4”.

Who should look elsewhere

• If you want a throttle, get the Aventure 3. Aventon sells an aftermarket throttle that converts the M to Class 2, but it doesn’t come with one.
• If you want full suspension, the Mokwheel Obsidian has a rear shock.
• If you ride technical singletrack and want a lighter trail bike, the Ramblas uses the same family of A100 motor in a hardtail mountain bike frame.

Aventure M vs Aventure 3 vs Mokwheel Obsidian

Every figure comes from the current manufacturer pages.

The Aventure 3’s 1440W is Aventon’s Boost Mode figure. For the head-to-head between the two Aventons, see Aventure 3 vs Aventure M.

Auto mode and AutoShift on the trail

This is why you’d buy the bike. The modes are Off, Eco, Sport, Auto and Turbo. In Auto, the bike reads how hard you’re pushing on the pedals and adjusts the assist itself. I was worried Auto wouldn’t keep up on steep climbs, but it did.

The second part is the electronic rear shifter. Hold the back button until a blue light comes on, and the shifter goes automatic. It measures your torque and cadence and shifts for you. On a climb I started pedaling harder, my cadence picked up, and I felt it shift up twice. On a very steep pitch I had to slow down, and it shifted me into a lower gear. Going downhill, it shifts up.

With both on, I didn’t have to think about gears or assist on any terrain. Aventon runs it through a Shimano Cues 10-speed with an 11 to 39 tooth cassette.

Motor and power

The motor is Aventon’s A100 mid-drive, a similar setup to the Ramblas. On paper it’s 250W sustained and 750W peak, with 100Nm of torque, and that’s why it’s Class 1 with assist up to 20 mph. Despite the 250W rating, it gave me all the power I wanted on steep inclines.

There’s no throttle, so Aventon added hill start assist. If you’re stopped on a hill, push down on the pedal and you feel a strong push from the motor right away. It makes up for most of what a throttle would do at a standstill.

In full Auto, pedaling hard, I lifted the front tire off the ground on purpose and still felt in control. If you try that, wear a helmet, and it’s at your own risk.

What the specs mean on the road

Mid-drive, 250W sustained, 100 Nm. A mid-drive drives the chain, so it works through the gears. The 250W rating didn’t feel weak to me on steep climbs.

Double-sided torque sensor. Aventon lists one. It measures how hard you push, and that’s what Auto mode and AutoShift use to decide how much help to give and which gear you need.

11-39 cassette with a 44T chainring. The 39-tooth cog is the climbing gear and the 11 is for speed.

The crank doesn’t spin the chain. In the video I pointed out that the crank is tied to the motor, not the chain, so the chain only moves when you pedal forward. It’s a slightly different feel from a hub-motor bike.

733Wh battery, 85 miles. That’s the same capacity as the Aventure 3, which Aventon rates at 65 miles. I didn’t test range, so I can’t say where the 20-mile difference comes from.

Class 1. Adding Aventon’s throttle makes it Class 2, which some trails don’t allow.

73 lbs, 400 lb limit. It’s heavy, so plan on a strong rack. The 400 lb limit covers you plus your gear, so at 200 lb I had plenty of margin.

Brakes, fork and comfort

The brakes are SRAM DB4 hydraulic discs, and they have plenty of stopping power. Aventon lists a 200mm front rotor. The Aventon-branded fork has 80mm of travel and a lockout.

The suspension seatpost is the main comfort upgrade. On rocky ground and in the woods, it’s much more comfortable than a fixed post. It’s almost like having a dual suspension bike without the rear suspension. Add the 26 x 4.0 puncture-resistant tires, and rough trails get noticeably softer.

The saddle is Aventon-branded and co-branded with 3D Groove. It has a little more dip in the middle than the Aventon seats I’d been testing, but it feels about the same.

Commuter features

The full color display connects to Aventon’s app, and a location dot shows on the display. Aventon lists GPS tracking and an integrated lock. The turn signals show on the center display, and the integrated rear brake lights blink as turn signals too. Front and rear fenders come standard, and so does an integrated rear rack, rated at 59 lb. The grips are easy to swap with a single nut if you prefer a different shape. With integrated lights front and back and the included fenders, I said you could easily commute on it, even in bad weather.

Mine was the blue color, which reminds me of a Sprinter van’s gray blue.

A commenter asked about panniers. Aventon no longer sells its panniers, so plan on a third-party rack bag. I said the rack easily fits your bags.

Fit

I’m about 6’1” and 200 lb, and I rode the Large. Aventon’s sizing puts the Large at 5’10” to 6’4” and the Regular at 5’3” to 5’10”. The total weight limit is 400 lbs.

FAQ

Is the Aventure M a mid-drive?

Yes. It uses Aventon’s A100 mid-drive, rated 250W sustained, 750W peak and 100Nm.

Aventure M vs Aventure 3: which should I buy?

In my July 2025 Aventure 3 video, the Aventure 3 was my top pick. In this September 2025 video, I said the M had taken its place. The M gets the mid-drive, Auto mode, AutoShift and hill start assist. The Aventure 3 keeps a throttle, a 750W hub motor and a lower price. If you want the bike to handle the shifting and you don’t need a throttle, get the M.

Aventure M vs Velotric Summit 2?

I haven’t ridden the Summit 2, so I can’t compare them directly. For a go-anywhere job, the Aventure M is the one I’d buy. Just know it has no throttle, and as a Class 1 bike its assist stops at 20 mph.

How does it do off road?

Very well. It climbed steep inclines in Auto without running out of power. The suspension seatpost and fat tires smoothed out rocky sections.

Can I add a throttle?

Aventon lists an aftermarket throttle that converts it to Class 2. Check your local rules first in the e-bike laws by state guide.

What’s the range?

Aventon rates it at up to 85 miles from a 733Wh battery. I didn’t run a range test.

Is it the best mid-drive fat tire e-bike under $3,000?

At $2,899 as of Oct 22, 2026, it fits the budget. It’s also the bike I’d buy for a go-anywhere job.

Price

Aventon lists the Aventure M at $2,899 as of Oct 22, 2026. That’s $900 more than the Aventure 3 at $1,999 as of the same date. The difference buys you the mid-drive, Auto mode, AutoShift and hill start assist. You give up the throttle.
