Born from a skunkworks team at Rivian, the electric carmaker best known for its pickup trucks and SUVs, a group of engineers is now applying that same magic DNA to smaller wheels. An e-bike like a futuristic promise: sleek, software-driven, and distinctly Rivian in spirit.
Their new spinoff, called Also, has unveiled the TM-B, a high-tech, modular e-bike that reimagines what pedal-assist transportation can be. The most radical feature is the bike’s pedal-by-wire system, called DreamRide. And the fact that it is a commuter, trail, or gravel bike, all in one.
Pedaling to power a generator
Instead of using a traditional chain or belt, the TM-B converts pedal input into electrical signals that power a rear-mounted motor. It is a concept closer to drive-by-wire cars than to classic bicycles.
You can think of the TM-B’s pedal-by-wire drivetrain as conceptually similar to how an EREV (Extended-Range Electric Vehicle) works, where a generator powers the wheels, except scaled down and the generator being human-powered instead of by a small combustion engine.
The result, Also claims, is a smoother, quieter, and more adaptable ride, with regenerative braking that can recover up to 25 percent of the bike’s energy.
City or gravel bike?
Riders of the TM-B can choose from a suite of built-in ride modes, including All Purpose, Sport, Conserve, and Trail, each of which adjusts how the bike responds in terms of acceleration, torque, and top-speed behavior. Additionally, the bike is equipped with a front suspension fork that offers 120 mm of travel, providing significant shock absorption even on rough surfaces.
The TM-B rolls on 24-inch wheels wrapped in 2.6-inch tires, a slightly smaller but wider setup that strikes a balance between agility and stability. Also offers two configurations.
A Road Package with smoother tread is designed for city riding, while an All-Terrain Package, co-developed with Kenda, features a more aggressive pattern for gravel and uneven surfaces. It’s a design that reflects Rivian’s all-surface DNA, equally at home on urban bike lanes or weekend trails.
Two battery options
Two battery options, roughly 538 Wh and 808 Wh, promise ranges of up to 100 miles (160 km). A 5-inch touchscreen display brings software features more typical of Rivian’s vehicles, including over-the-air updates, navigation, and app-based locking.
It acts as a command center, showing navigation, speed, and ride stats while handling system updates and diagnostics. Through a mobile app, riders can personalize profiles, lock or unlock the bike, and receive anti-theft alerts. That’s something we also see on other premium e-bikes.
USB-C charging for your phone
One of the TM-B’s more thoughtful touches is its USB-C charging system. The removable battery pack not only powers the bike. It can also power your devices. Riders can plug in a phone, GPS unit, or even a small laptop directly into USB-C ports integrated into the battery housing.
This bidirectional design echoes Rivian’s approach in its electric trucks, where onboard outlets let users charge tools or camping gear. For cyclists, it means your e-bike becomes a mobile power bank, capable of recharging a smartphone several times or keeping navigation gear running during long rides.
Even the bike’s handlebar display and control electronics can draw power from these ports, allowing future accessories, such as lights, cameras, or even heated grips, to tap into the same energy source.
It’s another example of how Also is thinking beyond the ride, treating the TM-B as a piece of connected technology rather than a simple vehicle.
No fixed frame style
Unlike most e-bikes, the Also TM-B isn’t built around a fixed frame style. Instead, it uses a modular ‘top frame’ concept — a structural section that can be swapped out in minutes without tools. This lets riders transform the same base bike into different configurations for commuting, cargo hauling, or two-up riding.
You can have a streamlined, single-rider setup designed for everyday commuting or leisure riding. A bench seat is a longer, padded seat that accommodates a passenger or adds room for a child seat.
Alternatively, you can make it a cargo platform, a utility version with a flat rack for boxes, panniers, or baskets, ideal for small deliveries or transporting gear.
Will it come to Europe?
In the US, the price for the Also TM‑B e-bike is $4,500 (€3,880) for the Launch Edition. A base version is expected later, priced at under US $4,000.
Also has publicly stated its ambition to expand globally, and Europe is clearly on the roadmap. In their launch announcement, the company said the TM-B will be part of a ‘broader platform’.
The TM-B will likely be adjusted for different regions, with a 250 W output version planned for the EU. While the exact timing and pricing for the European market haven’t been disclosed yet, pre-orders are already open, with an expected first delivery window in spring 2026.
In the United States, the TM-B is positioned as a Class 3 e-bike, offering pedal-assist speeds of up to 28 mph (45 km/h). Early reviews describe it as powerful yet smooth, with the pedal-by-wire system delivering instant torque and a near-silent ride.
Speed pedelec or not?
However, when the bike crosses the Atlantic, things will look different. Also has confirmed plans to adapt the TM-B to local regulations, which in Europe and notably Belgium, means assistance will likely be capped at 25 km/h with a 250 W nominal motor output.
This keeps it within the EU’s legal definition of a pedelec, a category that enjoys full access to bike lanes and requires no registration, license, or insurance.
If the company were to retain the 45 km/h capability of the US version, the TM-B would instead be classified as a speed-pedelec or moped under Belgian law. That would bring stricter conditions: a registration plate, insurance, and a certified helmet, with the bike restricted to roads in some cities rather than standard cycle paths.
Beyond bicycles
Also isn’t stopping at bikes. The company is developing a full family of small electric vehicles, including a four-wheel pedal-assist cargo quad aimed at urban deliveries and fleet use.
Early prototypes resemble compact electric vans for bike lanes — able to haul hundreds of kilos while remaining narrow enough for city infrastructure. The firm’s mission, inherited from its Rivian roots, is to apply EV-grade engineering and software to micromobility platforms of every shape, from commuter bikes to logistics vehicles.
