DJI Avinox MGU Explained: How to Read the Drive System’s Specifications

When comparing an Avinox-equipped e-bike, the motor headline is only one part of the decision. A drive unit’s torque and peak-power figures do not establish a bike’s range, total weight, handling, legal classification or real-world performance. Those outcomes depend on the battery, bicycle design, market configuration and riding conditions.

This guide explains how to read specifications for the Avinox MGU system without mixing component-level figures with complete-bike figures. It covers published Avinox drive-system documentation, not the separate Avinox MG concept or any individual e-bike review.

What the Avinox MGU system is — and what this guide covers

In Avinox documentation, the central powered component is generally described as a drive unit. The Avinox system uses a mid-drive motor, meaning the motor is mounted around the bicycle’s crank area and delivers assistance through the drivetrain rather than through a wheel hub.¹

The complete drive system includes more than the drive unit. DJI and Avinox documentation identifies a battery, controller functions, sensors, display and app as relevant parts of the wider system.² On an integrated e-bike, some of these elements may be physically combined or hidden within the frame and drive-unit assembly, but they remain different specification categories.

That distinction matters because marketing material can place several numbers close together: motor power, torque, battery energy, bike weight and claimed range may all appear on one product page. They should not be read as though they describe the same component.

For this article:

MGU/drive unit refers to the motor-and-drive assembly at the crank area.
Battery refers to the energy-storage pack, usually specified in watt-hours.
Drive system refers to the connected motor, battery, electronics, sensors, display and software ecosystem.
Complete bicycle means the finished e-bike, including its frame, suspension, wheels, tyres, drivetrain and market-specific configuration.

Avinox was introduced by DJI at Eurobike in July 2024 as an e-bike drive-system family.³ That product-family context does not mean every published Avinox figure applies to every drive-unit version or every e-bike fitted with the system.

Start with the specification boundary: motor, battery, system and bicycle

A useful comparison starts by asking a simple question: what exactly does this number describe?

Specification	Usually belongs to	What it can tell you	What it cannot establish alone
Rated power, peak power, torque, maximum cadence	Drive unit	The motor’s published output limits or operating characteristics	Whole-bike acceleration, climbing speed or legal classification in every market
Watt-hours, amp-hours, nominal voltage, battery mass	Battery	Stored energy and battery-level mass	Actual range on a particular bike or route
Assist modes, display, app settings, Walk Mode	Drive system	Available control functions and configurable behaviour	The mechanical quality of the complete bicycle
Total mass, tyre size, suspension travel, gearing, range claim	Complete bicycle	The specification of a specific production model	The capability of every bike using the same motor

The Avinox drive-system guide makes the same broad separation: motor specifications normally include power, torque and mass, while battery specifications include energy, capacity, voltage, mass and energy density.²

For buyers, this is particularly important when comparing two bikes that use the same Avinox drive unit. One may have a larger battery, heavier casing, longer-travel suspension and more aggressive tyres. The motor may be unchanged, while the riding result differs substantially.

For importers and industry readers, the same boundary helps prevent specification errors in listings and technical documents. A supplier’s motor figure should not be copied into a complete-bike range claim, and a bicycle’s total weight should not be presented as drive-unit mass.

How to interpret MGU power, torque, cadence and weight figures

Rated power is not peak power

Rated power is the sustained nominal output figure used in a product specification. Peak power is a higher maximum figure that may be available only under particular operating conditions or for a limited period. They answer different questions and should not be compared as if they were interchangeable.

The Avinox FAQ states that the rated power for all listed Avinox drive units is 250 W. It lists different peak-power figures for M1, M2 and M2S drive units, with an explicit condition attached to the M2S figure: the stated 1,500 W value is measured in Boost mode under specified test conditions when paired with an FP700 or RS800 battery. The FAQ states lower peak output when M2S is paired with an FS600 or FS800 battery.¹

That qualification is a useful reminder for every system comparison:

Confirm the exact drive-unit model.
Confirm whether the number is rated, peak, regular-assist or Boost-mode output.
Check the battery pairing and stated measurement condition.
Check whether the manufacturer’s page applies to the target market.

There is also a reason to verify the current source rather than repeating a number from a single page. DJI’s Austria product-specification page for the M1 lists 250 W rated power and 850 W peak power, while the current Avinox FAQ lists 1,000 W peak power for the M1.⁴¹ The supplied documentation does not, by itself, explain why those figures differ. They may reflect different documentation versions, configurations or measurement conventions. The practical conclusion is not to average them or select the larger figure; it is to use the specification tied to the exact model, market and current product documentation being considered.

Torque needs its own label

Motor torque is expressed in newton-metres (N·m). It describes rotational force, not electrical power and not a direct prediction of climbing performance.

The M1 specifications page lists a maximum continuous torque of 105 N·m.⁴ Separately, the Avinox FAQ describes M1 output as up to 105 N·m in regular assist modes and up to 120 N·m in Boost mode.¹ These labels matter. “Maximum continuous torque,” “regular-assist torque” and “Boost-mode torque” should not be silently treated as the same measurement.

A high torque figure may be relevant to low-cadence starts or steep terrain, but the result at the rear wheel also depends on the selected gear, wheel size, tyre grip, rider input, controller calibration and whether the system permits the relevant mode in that situation. It is therefore better to use torque as one comparison point within the same documentation framework, not as a universal ranking of e-bikes.

Maximum cadence describes pedalling compatibility

Cadence is the rider’s crank rotation rate, measured in revolutions per minute (rpm). A published maximum cadence indicates the upper pedalling speed at which the system is designed to continue supporting assistance within its operating rules.

For M1, DJI lists a maximum cadence of 150 rpm.⁴ This is not a statement that riders should pedal at 150 rpm, nor does it describe a bicycle’s top speed. It is primarily a system-operating parameter that can matter to riders who pedal at high cadence, particularly in changing terrain or with certain gearing choices.

Drive-unit weight is not e-bike weight

The M1 drive-unit mass is listed as approximately 2.52 kg on DJI’s M1 specifications page.⁴ This is useful when assessing frame integration or comparing motor assemblies. It is not the weight of an Avinox-equipped bicycle.

A complete e-bike adds a frame, fork or rear suspension, battery, wheels, tyres, drivetrain, brakes, cockpit, display hardware and accessories. Two bikes with the same drive unit can therefore differ materially in total mass.

Battery specifications: read watt-hours before making range comparisons

Battery specifications can look technical, but the first useful number for most comparisons is watt-hours (Wh).

Watt-hours measure stored energy. In simple terms, a battery with a larger Wh figure can store more energy than a smaller Wh battery, assuming the published figures use the same basis. It does not guarantee a proportional increase in real-world range.

Other common battery figures include:

Amp-hours (Ah): electrical charge capacity.
Nominal voltage (V): the battery system’s stated operating voltage.
Battery mass: relevant to complete-bike weight and handling.
Energy density (Wh/kg): stored energy relative to battery mass.

Avinox’s system guide lists these as the usual categories for battery specifications and identifies Wh as energy stored in the pack.²

Why Wh is more useful than Ah for first comparisons

Ah alone does not show stored energy unless voltage is also known. A simplified relationship is:

Watt-hours ≈ nominal voltage × amp-hours

This is why two battery packs with the same Ah rating can have different energy capacity if their nominal voltages differ. For a first comparison between compatible e-bike battery options, Wh is generally the clearer starting point.

However, a larger battery does not automatically produce a fixed percentage increase in range. Actual energy consumption changes with rider mass, cargo, terrain, elevation change, wind, temperature, tyre pressure, tyre construction, speed, assist mode and riding style. A heavier battery may also slightly alter the bike’s total mass.

Range should therefore be read as a complete-bike claim, not as a battery specification. If a bicycle manufacturer publishes a range estimate, check whether it states the battery size, selected mode, route profile, rider assumptions, speed and test method. Without those conditions, the number can be useful only as a broad manufacturer estimate.

Assist modes, Boost and legal assistance speed are separate specifications

Assist modes describe how the system responds to rider input. They are not the same as the legal speed at which assistance stops, and they are not automatically equivalent to a fixed motor-power output.

For the M1, DJI lists Auto, Eco, Trail, Turbo and Boost modes, along with Walk Mode.⁴ The M1 page also publishes mode-level torque and support settings, including app-adjustable ranges for some modes. In Auto mode, the system uses sensor input and bike-attitude data to adjust support; the product information document says the system’s built-in IMU detects pitch and roll and can adjust assistance in Auto mode.⁵

Boost deserves careful reading. It is a selectable function with its own published output conditions, not a figure that should be assumed to be continuously available in every mode. The user manual also warns riders to understand the system functions and follow the bicycle manufacturer’s instructions before use.⁶

Assistance cut-off speed is market-specific

The DJI Austria M1 specifications page lists maximum assistance speeds of 25 km/h for Europe and China and 32 km/h for North America.⁴ These are regional product-page statements, not a universal rule for every market, model year or bicycle configuration.

Legal requirements may vary by jurisdiction and can depend on factors beyond a motor’s headline output. Buyers and importers should verify the applicable local rules and the precise regional configuration of the finished bicycle. A motor capable of a certain output does not, by itself, establish how a particular e-bike is classified for road use.

Why an Avinox-equipped bike can differ from published MGU figures

The drive unit is important, but it is only one subsystem. Two Avinox-equipped e-bikes may differ in practical use because of:

battery capacity and battery type;
frame material and frame size;
hardtail or full-suspension layout;
suspension travel and setup;
wheel diameter, rim width and tyre casing;
gearing range and drivetrain components;
brake specification;
total bicycle mass;
firmware and permitted app settings;
local speed-limit configuration; and
rider, route and weather conditions.

The Avinox system documentation notes that system settings can be personalized through the app, including bike-screen display and assist parameters.⁵ That does not mean every setting is unrestricted: the bike manufacturer, firmware version and local configuration may define what is available on a particular model.

A practical comparison method is to make two separate lists. First compare drive-system facts: MGU version, rated power, peak-power conditions, torque labels, battery Wh and market setting. Then compare bicycle facts: total mass, geometry, suspension, wheel and tyre specification, gearing, brakes and manufacturer-stated range conditions.

This avoids a common mistake: assuming that two bikes with the same M1, M2 or M2S designation will ride alike or have the same range.

A practical checklist for comparing Avinox MGU system specifications

Before making a purchase, sourcing decision or product comparison, use this sequence:

Identify the exact drive-unit version. Do not apply M1, M2 or M2S figures interchangeably.
Check the source market and publication date. Assistance-speed and output figures can be region- or documentation-specific.
Separate rated from peak output. Record whether the figure is quoted in normal assistance or Boost mode.
Read torque labels exactly. Maximum continuous, regular-assist and Boost torque are different claims.
Confirm battery pairing. For conditional peak-power figures, battery type can be part of the specification.
Compare battery energy in Wh. Use Ah and voltage as supporting details, not as substitutes for Wh.
Assess the complete bike separately. Check weight, tyres, gearing, suspension, brakes and included equipment on the bicycle manufacturer’s specification page.
Treat range as an estimate. Give greater weight to claims that disclose battery size and test conditions.
Verify local compliance separately. Use the actual market configuration and applicable local requirements rather than a generic motor description.

Frequently asked questions

What does MGU mean in the DJI Avinox system?

In the supplied Avinox materials, the main motor assembly is described as a drive unit. “MGU” is commonly used as shorthand for a motor-and-gear drive assembly, but buyers should rely on the exact model designation shown in the current Avinox or bicycle documentation rather than assuming that every use of the term refers to the same hardware.

Is rated power the same as peak power on an Avinox drive unit?

No. Rated power is the published nominal output figure, while peak power is a higher maximum figure that may depend on operating mode, test conditions and battery pairing. The Avinox FAQ attaches specific conditions to at least some M2S peak-power figures.¹

Does a larger Avinox battery automatically mean a longer real-world range?

A larger Wh figure means more stored energy, but actual range also depends on the bicycle, assist mode, terrain, temperature, rider input, tyres and speed. Compare Wh first, then review any bicycle-level range estimate and its stated conditions.

Are Avinox assistance-speed limits the same in every market?

No. DJI’s M1 page lists different maximum assistance speeds for Europe and China than for North America.⁴ Confirm the specification for the intended sales market and the finished bicycle configuration.

The key takeaway is simple: read Avinox specifications in layers. Start with the exact drive unit, then the battery and software conditions, and finally the complete bicycle. That approach makes published figures more useful while avoiding claims that the component documentation does not support.
