As one of the most trusted publications dedicated exclusively to e-bikes, Electric Bike Journal has built its reputation on deep technical insight, real-world testing, and credible evaluations of the latest electric bikes.
Known for spotlighting innovation that genuinely moves the category forward, the publication recently took a first look at the Tambora AE gravel bike, praising it as a model that redefines the boundaries of adventure and utility within the fast-growing electric gravel bike segment.
Positioned as a versatile electric gravel bike built for riders who want to go further, faster, and more comfortably, the Tambora AE immediately stood out in Electric Bike Journal’s coverage for blending performance-driven engineering with thoughtful, adventure-ready design.
First Impressions: Comfort Meets Confident Power
From the first shakedown rides, Electric Bike Journal reported being “beyond pleased” with how the Tambora AE balances comfort, control, and motor assistance. Built around a lightweight ACX carbon frame and fork, the gravel bike delivers a ride feel that’s firm and responsive under power, yet noticeably smooth over rough gravel and broken pavement.
The dropped seatstay design plays a key role here, helping dampen vibrations during long rides while preserving stiffness through the short 432mm chainstays.
According to the review, this combination creates an ideal platform for extended days in the saddle, whether on mixed-surface routes, gravel backroads, or high-speed tarmac stretches.
Power comes from the Bosch Performance Line Sprint motor, a Class 3 system delivering pedal assist up to 28mph. Electric Bike Journal highlighted the motor’s quick acceleration and preference for higher cadence, rewarding riders who enjoy maintaining momentum and speed across rolling terrain and longer climbs.
In real-world testing, maintaining an average of around 20mph in Eco and Tour+ modes felt achievable and efficient, reinforcing the Tambora AE’s all-day riding credentials.
Engineered for All-Terrain Exploration
Electric Bike Journal also emphasized how thoughtfully the Tambora AE is engineered for adaptability, an essential trait for any contender among the best gravel bikes in the electric category.
One of the standout features is the fork-mounted FLIP CHIP system, which allows riders to fine-tune geometry between a longer, more relaxed setup and a shorter, more aggressive riding position. Learn more about the FLIP CHIP technology here!
This adjustability impacts head tube angle, wheelbase, and bottom bracket height, giving riders the flexibility to prioritize stability and comfort for adventure rides or sharpen handling for faster, performance-oriented outings.
With clearance for up to 45c tyres and stock 40c Schwalbe G-One Allrounds, the Tambora AE confidently straddles the line between gravel bicycle and high-speed road companion.
The lineup includes two distinct builds: the AE-GRX with Shimano GRX 1×12 and the AE-GX featuring a wireless SRAM Rival eTap AXS and GX Eagle mullet drivetrain. Both models roll on carbon Novatec G24 wheels and use an integrated Bosch Compact Tube 400 battery, with the option to add a Powermore 250 range extender, pushing estimated range up to approximately 73 miles.
Product Takeaway
As highlighted by Electric Bike Journal, the Tambora AE gravel bike delivers a compelling mix of comfort, power, and versatility that sets it apart in the evolving electric gravel bike space.
Whether you’re expanding your adventure routes or elevating everyday rides, Tambora AE proves that a modern gravel bike can be both technically advanced and genuinely enjoyable across all terrain.
