Aventon significantly expanded its market reach when the company rolled out its first Aventure e-bike in 2021. Now the brand has updated the hot-selling e-bike with key upgrades. And of course we made sure to get an early look at the bike to tell you exactly how it looks, feels, and rides. Check out my complete review of the Aventon Aventure.2 below.
The e-bike includes a number of upgrades, but perhaps the most important is the inclusion of a new torque sensor.
For those that have had the pleasure of riding an e-bike with a well-designed torque sensor, you’ll know that it seriously improves the riding experience. When you press on the pedals, you get near-instantaneous pedal assist response. It’s fast, it’s intuitive, and it just feels better.
But that’s not the only upgrade. The Aventon Aventure.2 comes with several new pieces of kit including a rear rack as standard equipment, upgraded taillights with built-in turn signals, and a new pedal-assist layout with four power levels.
You can check it all out in my review video below, but you’ll want to keep reading afterward for even more detail.

Real quick, I want to start with the packaging. I know this is an e-bike review, not a box review. But Aventon deserves credit for replacing nearly every single piece of plastic and foam packaging normally included in e-bike packaging with more sustainable alternatives from recyclable material.
Plastic sleeves are replaced with cardboard. Foam is replaced with expanded fiberboard blocks. Even the plastic cable ties are replaced with kraft paper rope. It’s frankly incredible. Bravo.
Okay, now back to your regularly scheduled e-bike review.
How well does this adventure e-bike ride?
The Aventure.2 is a big bike, there’s no tip-toeing around that. But it doesn’t feel quite as big as it looks. Somehow the e-bike retains a level of grace that doesn’t seem to fit its big and brawny appearance.
That translates into a fat-tire e-bike that actually works quite well on the road too, even if it was designed to handle the trails as well.
But off-roading is where this e-bike shines, and it’s also where that new torque sensor makes the biggest difference. Getting rolling on a big, heavy e-bike like these fat-tire e-bikes can be tricky, especially if you’ve forgotten to downshift (or just didn’t downshift far enough before stopping).
A torque sensor gives you near-instant motor response when you step on the pedal, instead of the laggy response of a cadence sensor that can take a pedal revolution or two to kick in. That’s a game-changer off-road where tricky terrain can compound a rough start.
The top speed of 28 mph (45 km/h) likely won’t have too much of an impact on most off-roaders since you rarely ever get the chance to go that fast on trails. But back on the road, rolling away from a stop sign or a green light is easier than ever with the new sensor setup and the higher speed makes this a serious commuter contender for anyone who regularly shares the road with cars.
If you do most of your commuting in the bike lane though, go easy with the Class 3 speeds. This is a big and heavy e-bike to come barreling down on other riders.
There are also four new levels of pedal assist selectable on the color LCD screen, and a color-coded label makes it easier to see which level you’re in at a quick glance.
For on-road riders that enjoy fat-tire e-bikes for their ability to nearly erase potholes, you’ll be happy to see two other inclusion: a rear rack and turn signals.
The rear rack is no longer behind a paywall but instead comes as standard equipment. And don’t get me started on how awesome these turn signals are. In the past I’ve ribbed e-bikes with turn signals when those signals were so close together that they failed to serve their indicator purpose. But with Aventon’s signature taillights mounted on either side of the rear wheel as integrated frame lighting, the turn signals are actually far apart and quite apparent in their role as directional indicators.
I still think riders shouldn’t completely rely on e-bike turn signals since most drivers are not expecting to see a blinking indicator on a bike. So I generally still use hand signals, but it’s nice to have a turn signal setup that gives you the best chance of drivers correctly interpreting your intentions.
I also really like how Aventon gives you plenty of options for frames. Not only is there a step-through AND a step-over option, but both are available in two frame sizes.
Not everything here is rosy though. I was a bit bummed to see Aventon stick with the same 48V 14Ah battery size. That 672 Wh battery is fine, don’t get me wrong. But it’s not as big as I would have liked. It will give you plenty of range if you’re sticking to lower pedal assist levels, such as Aventon’s real-world range rating on Level 1 at 60 miles (96 km).
The 30-mile (48 km) range rating on throttle-only riding isn’t bad either, but riders who generally go faster off-road will likely burn through that battery even quicker. If they could have found a way to stuff one more row of cells into that battery for a 17.5Ah setup and an 840Wh capacity, I’d be over the moon. But as it stands, the Aventure.2 still gets great range on pedal assist on the road and respectable range off-road or on throttle. Though that doesn’t mean I can’t still beg for more.
The only other downside for me is just that the bike is kind of huge. It’s big and heavy. But that’s what you get with an adventure e-bike. You’re not going to traverse the same terrain on a 20″ folding e-bike, so you’ve got to pack more in to go explore rougher and tougher places.
All told, you’re getting one hell of a bike here for a more than reasonable price of $1,899. Punchy hydraulic brakes, a good suspension setup with comfort-enhancing fat tires, awesome LED lighting in the front and rear, and a torque-sensor to boot! There’s just so much to be happy about with the Aventon Aventure.2 that I almost feel bad complaining about the average-size battery or heavy weight. Almost, but not quite. I’ll still complain. But I’ll do it while wearing a huge smile on my face as I sling sand and rocks around my local trails on this fun and adventurous e-bike.
Oh and by the way, if you want a deal on Aventon’s original cadence sensor-based Aventure, that model is now on sale for $1,499. That’s a freakin’ steal!

Silicon anodes appear to be leading the way in the race to commercialize next-generation battery technologies for electric vehicles.
The buzz around silicon-based anodes, which promise improved power and faster charging capabilities for EVs, has been growing in recent months — just as the hype around solid-state batteries seems to have fizzled.
It comes as increasing EV sales continue to drive up global battery demand, prompting auto giants to team up with major cell manufacturers on the road to full electrification.
While some OEMs (original equipment manufacturers) have inked deals with solid-state battery developers, carmakers such as Mercedes, Porsche and GM have all bet big on silicon anodes to deliver transformative change in the science behind EVs.
A recent report from consultancy IDTechEx described the promise of advanced silicon anode materials as “immense” for improving critical areas of battery performance, noting that this potential hadn’t gone unnoticed by carmakers and key players in the battery industry.
It warned, however, that challenges such as cycle life, shelf life and — perhaps most importantly — cost, need to be addressed for widespread adoption.
Venkat Srinivasan, director of the Collaborative Center for Energy Storage Science at the U.S. government’s Argonne National Laboratory in Chicago, said silicon anodes appear to have the edge over solid-state batteries.
“If there’s a horse race, silicon does seem to be ahead at least at this moment, but we haven’t commercialized either one of them,” Srinivasan told CNBC via videoconference.
Srinivasan said five years ago silicon-anode batteries had a calendar life of roughly one year, but recent data appears to show a dramatic improvement in the durability of these materials, with some tests now projecting a three to four-year calendar life.
Unlike the cycle life of a battery, which counts the number of times it can be charged and discharged, the calendar life measures degradation over time. Typically, the calendar life of a battery refers to the period in which it can function at over 80% of its initial capacity, regardless of its usage.
Srinivasan said solid-state batteries, long billed as the “holy grail” of sustainable driving, still have a long way to go before they can match the recent progress made by silicon anodes.
“That transition still has to be made in solid-state with their metal batteries and that’s why I think you’re hearing from people that, hey, it looks like that promise hasn’t panned out,” Srinivasan said.
“That doesn’t mean we won’t get there. It may happen in a few years. It just means that it feels like today silicon is in a different part of the technology readiness level.”
Silicon anodes vs. solid-state batteries
Analysts say silicon anodes theoretically offer 10 times the energy density as graphite, which are commonly used in battery anodes today. Yet, these same materials typically suffer from rapid degradation when lots of silicon is used.
“Silicon anodes and solid-state batteries are two emerging technology trends in the EV battery market aimed at pushing the boundaries of high-performance battery cells,” Rory McNulty, senior research analyst at Benchmark Mineral Intelligence, told CNBC via email.

It has typically been the case that better battery performance comes at the cost of longevity or safety, McNulty said. Silicon anodes, for example, are known to swell significantly during charging, which reduces the battery’s longevity.
By comparison, McNulty said solid-state batteries were claimed to greatly improve the stability of the electrolyte to high performance electrode materials, combating the challenges of using high energy density materials such as silicon and lithium.
As the name suggests, solid-state batteries contain a solid electrolyte, made from materials such as ceramics. That makes them different from conventional lithium-ion batteries, which contain liquid electrolyte.
Especially in the West, advances in the area of silicon anodes [are] seen as strategic opportunity to catch up with China.

Japan’s Toyota and Nissan have both said they are aiming to bring solid-state batteries into mass production over the coming years, while China’s SAIC Motor Corp reportedly said in early September that its MG brand would equip cars with solid-state batteries within the next 12 months.
Nonetheless, analysts remain skeptical about when solid-state batteries will actually make it to market.
A strategic opportunity?
“Silicon based anodes promise to be the next-generation technology in the anode field, providing a solution for faster charging,” Georgi Georgiev, battery raw materials analyst at consultancy Fastmarkets, told CNBC via email.
Georgiev said several industry players have been looking into the potential of silicon anodes, from well-established anode suppliers in China and South Korea to new players like Taiwan’s ProLogium and U.S. manufacturers Group14 and Sila Nanotechnologies.
“Especially in the West, advances in the area of silicon anodes [are] seen as strategic opportunity to catch up with China, which dominates the graphite-based anode supply chains with Chinese anode producers holding 98% of the global anode market for batteries,” Georgiev said.
“However, there are significant technical challenges going to 100% silicon anode such as silicon expansion affecting the longevity of the batteries and currently there are several routes to produce silicon anodes,” he added.

Taiwanese battery maker ProLogium debuted the world’s first fully silicon anode battery at the Paris Motor Show last month, saying it’s new fast-charging battery system not only surpassed traditional lithium-ion batteries in performance and charging efficiency but also “critical industry challenges.”
ProLogium, citing test data, said it’s 100% silicon anode battery could charge from 5% to 60% in just 5 minutes, and reach 80% in 8.5 minutes. It described the advancement as an “unmatched achievement in the competitive EV market,” which will help to reduce charging times and extend the range of EVs.
Fastmarkets’ Georgiev said a big question mark over the commercialization of silicon anodes is the cost of production and whether any of the major silicon-anode producers “could produce material at scale with a consistent quality and at a competitive price — [a] major requirements of OEMs.”
“At this stage silicon anodes are used more as an additive to graphite-based anodes and in the years to come we expect to see increase of silicon share in anode, but in combination with graphite, while 100% silicon anodes will take longer time to enter the mass market,” he added.
Saudi Aramco’s Ras Tanura oil refinery and oil terminal

Saudi state oil giant Aramco reported a 15.4% drop in net profit in the third-quarter on the back of “lower crude oil prices and weakening refining margins,” but maintained a 31.05 billion dividend.
The company reported net income of $27.56 billion in the July-September period, topping a company-provided estimate of $26.9 billion. The print is also a 5% drop from the previous quarter, which came in at $29.1 billion, as lower global oil prices, weaker demand and prolonged OPEC+ production cuts led by Saudi Arabia continue to impact crude prices.
The average selling price of oil for the second quarter of 2024 stood at $85 per barrel, but dropped to $78.7 per barrel during the third quarter, according to Saudi-based bank Al Rajhi capital, as non-OPEC supply volumes grew.
The oil firm said its year-on-year decline was partly offset by a “reduction in selling, administrative and general expenses primarily driven by a gain from derivative instruments, and a decrease in production royalties largely reflecting lower crude oil prices and a lower average effective royalty rate compared to the same quarter last year.”
Aramco’s dividend includes a base payout of $20.3 billion and an atypical performance-linked one of $10.8 billion. The Saudi government and the kingdom’s sovereign wealth vehicle, the Public Investment Fund, are the main beneficiaries of the dividend, holding stakes of roughly 81.5% and 16% in the company.
The remaining shareholding trades freely on Saudi Arabia’s Tadāwul stock exchange, with the company having finalized its second public share offering back in June.
Aramco’s earnings before Interest and Taxes (EBIT) came in at $51.45 billion in the third quarter, down 17% year-on-year. Aramco’s capital expenditure guidance was brought up 20% to $13.23 billion.
The company was trading at 27.45 riyals following the announcement, down 0.18% on the previous day.
The earnings align with a broader trend across oil majors, whose third-quarter profits have also suffered from declines in crude prices and refining margins. Aramco said it achieved average realized crude price of $79.3 per barrel in the third quarter, compared with $89.3 per barrel in the same period of last year.
Saudi Arabia, the world’s largest crude exporter who produces roughly 9 million barrels per day of crude at present, serves as the de facto leader of the OPEC+ oil producers’ alliance, a subset of whom agreed over the weekend to delay a planned December output hike by one month.
“Aramco delivered robust net income and generated strong free cash flow during the third quarter, despite a lower oil price environment,” CEO Amin Nasser said in a statement. “We also progressed our upstream developments, strengthened our downstream value chain, and advanced our new energies program as we continue to invest through cycles.”
The revenues will be a boon to the Saudi economy, which is currently undergoing a diversification process under Crown Prince Mohammed bin Salman’s legacy Vision 2030 scheme spanning a slew of high-cost infrastructure “gigaprojects.”
Earlier this year, Saudi Arabia’s Ministry of Finance cut the kingdom’s growth forecast to 0.8% in 2024, in a steep decline from a previous projection of 4.4%, and raised the outlook for the national budgetary shortfall to roughly 2.9% of GDP, from a prior indication of 1.9%.
