ALSO’s TM-B is not a Rivian-branded bicycle, but a separate micromobility product from a company spun out of Rivian’s electric-vehicle work. Its defining feature is a pedal-by-wire drivetrain: the pedals generate electricity, software manages the assistance, and a motor drives the wheel. The TM-B can also be reconfigured as a solo commuter, passenger bike, or cargo hauler.
That flexibility comes with important qualifications. ALSO’s published claims include up to 100 miles of range, 28-mph pedal assist, 180 Nm of wheel torque, and a 324-pound maximum payload, but the bike remains a premium, first-generation product with a refundable reservation and waitlist rather than ordinary immediate availability.

What is ALSO?
ALSO is a Rivian-related micromobility company focused on smaller electric vehicles rather than passenger cars. Rivian’s connection matters because the startup is drawing on ideas associated with modern electric vehicles: software-controlled systems, integrated batteries, connected security, vehicle-style controls, and a platform approach that can support multiple configurations.
However, the TM-B should not be called “Rivian’s e-bike” without explanation. The consumer product is made by ALSO, a separate company that emerged from Rivian’s micromobility work. Rivian’s name and engineering heritage provide context, but buyers should not assume that Rivian sells, services, warranties, or manufactures every TM-B directly. ALSO announced the TM-B alongside its TM-Q four-wheel pedal-assist vehicles in October 2025.
#1 Best Overall
- 1000 W Motor & Upgraded Display: The EB5 electric bike equipped with a 1000 W peak motor, boosted a top speed of 20 MPH. The display panel has adjustable backlight brightness from 1-5 levels. In addition, the upgraded LCD Display provides riding data support, such as ODO/MAX/AVG SPEED, PAS mode can be customized up to 3 modes
- Removable Large Battery: The EB5 e-bike is equipped with a 360Wh battery, which covers a range of up to 25-40 miles per charge for 5-6 hours so that it can meet travel or daily commute needs. Removable battery makes charging more convenient whether you are at home or in the office
- 4 Working Modes: PAS mode will assist you with a moderate amount of power as you pedal the bike, kick in 1-3 levels of pedal assist to suit your needs. In pure electric mode, you can twist the throttle in any increments of power you desire. Pedal mode allows the rider to pedal as an ordinary bike. Booster mode will help you push your EB5 at 4.5-7.5 km/h when uphill, which will save you a lot of efforts
- Riding Comfortably and Handily: The 26" puncture resistant tires are for greater durability. A high-strength front fork suspension, 7-speed gears, dual lights, LCD display, front and rear mechanical disc brakes can bring your riding more comforts, make your e-bike adapted to complex terrains and keep you safe
- Minimalist Appearance & Lightweight Frame: A highly efficient, city style affordable electric bicycle offering minimalist and sleek appearance and only weighs 49.6 lbs. The triangular high-carbon steel frame provides more stability
ALSO’s launch announcement describes a broader electric-mobility platform, while the TM-B is the company’s first major consumer bicycle.
How the TM-B’s pedal-by-wire drivetrain works
The TM-B does not use a conventional chain-and-gear connection between the pedals and the rear wheel. Its basic energy path is:
Pedals → generator → battery and control system → electric motor → wheel
When the rider pedals, the pedals turn a generator. That electrical input is interpreted by the bike’s control software, which commands the motor. The motor then drives the wheel. The rider is therefore producing electrical input rather than mechanically turning the wheel through a chain, cassette, and derailleur.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsALSO calls the system DreamRide and describes it as a software-driven pedal-by-wire system. The company says software can adjust assistance, cadence behavior, and simulated gearing. Launch coverage also reported regenerative braking and, where regulations allow, a powered throttle capable of reaching 20 mph; that throttle configuration should be confirmed for the buyer’s region rather than treated as universal.
Why the unusual drivetrain could be useful
- There is no conventional chain-driven drivetrain between the pedals and driven wheel.
- Software can change the riding feel without replacing mechanical gears.
- Automatic assistance and simulated gears may make varying rider strengths and loads easier to accommodate.
- The same control architecture could suit commuting, cargo, hills, and passenger use.
- Regenerative braking may recover some energy, although its real-world range benefit is not established here.
The trade-off is that mechanical simplicity in one area creates electrical dependence elsewhere. A failed chain is a familiar bicycle problem. A failure involving the generator, motor controller, sensors, display, firmware, or battery may require specialized diagnosis and parts. There is not yet enough public long-term service data to conclude that the TM-B will be more reliable, more efficient, or cheaper to repair than a conventional mid-drive e-bike.
What “modular” means on the TM-B
The TM-B’s upper-frame sections can be exchanged without tools. The published configurations include:
- Solo: a conventional individual riding setup.
- Bench/passenger: a longer seating arrangement for carrying another person where legally and safely permitted.
- Cargo: a rack-oriented setup for bags, groceries, and utility loads.
ALSO says the top frame can be swapped in seconds. The bike can also be specified with road or all-terrain tire setups, different handlebars, and accessories. In concept, one TM-B can replace a commuter bike on Monday, a family bike on Wednesday, and a cargo bike on Saturday.
The practical value depends on details that are not fully established on the public product pages. ALSO has not published a complete, universally applicable price list for every replacement frame module and accessory. Buyers should confirm whether modules are sold separately, whether a second configuration changes payload or handling limits, whether software settings change with the module, and how unused parts should be stored. A tool-free swap is useful only if the alternate module is affordable, available, and convenient enough to use regularly.

How to interpret the headline numbers
Up to 100 miles does not mean 100 miles for every ride. ALSO says range varies with terrain, rider weight, ride mode, weather, and other conditions. A passenger, heavy cargo, hills, cold temperatures, high assistance, and frequent acceleration can all reduce usable range.
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →The 180 Nm figure should also be treated carefully. It is presented as a wheel-torque claim, whereas conventional e-bike specifications often emphasize crank or motor torque. Those measurements are not directly interchangeable, so the number alone does not prove that the TM-B climbs better than a competing mid-drive bike.
A 28-mph pedal-assist limit generally resembles the U.S. Class 3 category, but local law controls where and how the bike can be used. A 324-pound maximum payload is the combined limit for the relevant load, not automatically a 324-pound rear-rack or passenger capacity.
Price, trims, and what the premium buys
Launch reporting put the TM-B’s Launch Edition and Performance versions at approximately $4,500. The base TM-B was described as costing less than $4,000 and having a smaller battery and fewer performance features. The current reservation page is not a complete public configuration-and-checkout page, so those launch figures should be distinguished from a confirmed current transaction price.
Higher trims appear to add features such as a larger battery, more assistance levels, a sport mode, higher-end suspension components, and additional equipment. Before reserving, a buyer should obtain the current build sheet and confirm:

Potential strengths in everyday use
One platform for several jobs
The strongest argument for the TM-B is flexibility. A household that needs commuting, errands, occasional passenger transport, and light cargo may prefer one configurable vehicle over multiple specialized bicycles. The small-wheel format, suspension, integrated lighting, and software controls are intended to make it feel more like a compact electric vehicle than a traditional bicycle.
Integrated technology
The touchscreen, app connectivity, location features, electronic lock, powerful lights, and removable USB-C power-bank battery could be useful to riders who value an integrated system. The security functions may also be more convenient than adding separate trackers and accessories, although a connected lock does not replace a strong physical lock or theft insurance.
Assistance and suspension
The claimed 10× assistance multiplier, 180 Nm of wheel torque, and 120 mm of front and rear travel suggest a bike designed for substantial loads, hills, and rougher surfaces. Those are manufacturer claims, not a substitute for an independent loaded-range, braking, hill-climbing, or trail test. Technical mountain-bike riders should also remember that a configurable utility bike is not automatically equivalent to a dedicated mountain bike.

What happens when the battery is empty?
ALSO has described a battery-empty or “limp” riding mode. The practical speed and effort required in that mode are important unanswered ownership details. Buyers should ask whether the bike remains comfortably pedalable, whether assistance disappears gradually or abruptly, and whether the display and controls continue working without battery power.
What if the electronics fail?
Ask what happens if the generator, motor, controller, touchscreen, phone connection, or firmware fails. Can the bike be pedaled home? Can it be unlocked without a phone? Is a cellular connection or subscription required for location and remote functions? What is the recovery process if the account is inaccessible or the phone is lost?
Weather and maintenance
The public launch material does not establish every water-resistance rating for the touchscreen, battery, connectors, and drive unit. Confirm the permitted weather exposure, charging requirements, storage temperature, and cleaning procedure. Also confirm where replacement tires, modules, battery packs, and electronic components can be obtained.
Passengers and cargo
The bench configuration should not be treated as automatic approval for carrying children. Verify the permitted passenger age and weight, foot protection, restraints, child-seat compatibility, and local regulations. Similarly, the 324-pound maximum payload does not tell you how much weight a particular rack or cargo module can carry or how the bike behaves when that load is mounted high or far behind the rider.
Transport and storage
The TM-B’s weight and unusual frame shape may matter more than its wheel size. Confirm whether a hitch rack is rated for the complete bike, whether the frame can be safely supported by that rack, and whether the bike fits through doors, into an elevator, or inside the intended storage area. A removable battery may reduce lifting weight, but it does not make the complete bike lightweight.

Legal classification is location-dependent
A 28-mph pedal-assist claim generally aligns with the commonly used U.S. Class 3 category, but marketing language does not determine every legal right. State and municipal rules can differ, particularly for throttles and passenger-carrying configurations.
Before riding, check:
- the local definition of a Class 3 e-bike;
- whether the specific TM-B configuration includes or permits a throttle;
- bike-lane and multi-use-path access;
- helmet and minimum-age requirements;
- passenger and child-transport rules;
- trail restrictions based on speed, weight, or tires; and
- rules governing transit, bike racks, and public charging or storage.
The TM-B is a rider-operated electric bike, not an autonomous vehicle. ALSO’s separate TM-Q commercial-vehicle plans should not be used to describe the TM-B as self-driving.
Who should consider the TM-B?
The TM-B is most compelling for a buyer who wants one premium vehicle for several local trips, values app-connected security and integrated controls, has secure storage and charging, and is comfortable with first-generation technology. It may suit a family that needs occasional passenger or cargo capability but does not want separate bicycles for every task.
It is less suitable for someone who needs a lightweight bike, wants immediate delivery, depends on a nearby ordinary bicycle shop for repairs, rides primarily technical mountain-bike trails, or wants the lowest cost per mile. It is also a poor choice for anyone unwilling to accept uncertainty around final configuration pricing, service coverage, replacement parts, or long-term software support.

| Alternative | Likely advantage over TM-B | Likely trade-off |
|---|---|---|
| Established long-tail or cargo e-bike | More proven child-seat, rack, parts, and dealer ecosystem | Less modular and less software-integrated |
| Premium commuter e-bike | Usually lighter, simpler, and easier to store | Less capable for passengers and large cargo loads |
| Utility e-bike with a conventional mid-drive | Familiar mechanical service model and established drivetrain parts | May have fewer connected features and less configurable ride behavior |
| Lower-cost e-bike plus trailer or child seat | Potentially better value and immediate availability | More separate equipment and less seamless switching between uses |
The right comparison is not just range or motor torque. Compare total cost, loaded range, passenger approval, rack capacity, weight, storage, legal access, repairability, warranty support, and delivery certainty. A conventional bike that is in stock and repairable locally may be more useful than a technically ambitious bike on a waitlist.
Questions to ask ALSO before reserving
- What is the current delivered price of each TM-B trim?
- Which solo, bench, and cargo modules are included, and what do additional modules cost?
- What is the current estimated delivery window for a new reservation?
- Can the bike be pedaled home if the battery, generator, controller, or display fails?
- Which features require a phone, account, cellular connection, or subscription?
- How is the bike unlocked if the phone or account is unavailable?
- What local service options exist, and which parts are stocked?
- What are the warranty terms for the battery, electronics, motor, and frame modules?
- What are the approved passenger, child-seat, rack, and payload limits for the selected configuration?
- What water-resistance, charging, and storage requirements apply?
Verdict
The TM-B is an unusually ambitious e-bike: its pedal-by-wire drivetrain, interchangeable upper frame, connected security, suspension, and integrated controls could make one compact vehicle useful for commuting, family transport, cargo, and recreation.
But the same features make it less like a conventional bicycle and more dependent on software, electronics, proprietary parts, and company support. At roughly $4,500 for the announced upper trims, the buyer is paying for flexibility and integration—not simply for range or motor power. With reservations still open and delivery timing having changed, the TM-B makes the most sense for an early adopter who values its configurable platform and can tolerate uncertainty. Buyers seeking immediate, repairable, proven transportation should compare established cargo, utility, and commuter e-bikes first.
