In-Wheel Motors Market Size, CAGR & Forecast, 2025-2035

In-wheel motors are moving from two-wheeler commodity to passenger-car drivetrain, tripling the market by 2035

Global spending on in-wheel motors reached USD 3.84 Billion in 2025, and Radial Insights expects USD 4.30 Billion in 2026 and USD 11.78 Billion by 2035, a CAGR of 11.86% over 2025-2035. Most of today's revenue still comes from low-cost hub motors in electric scooters, e-bikes and three-wheelers, while the value growth sits in passenger cars and vans.

This report covers electric traction motors packaged inside, or directly at, the wheel hub of road vehicles, sold as complete motor units with integrated bearings, and in car applications often with integrated brakes and inverters. It counts motors for electric two-wheelers and e-bikes, electric three-wheelers, passenger cars, light commercial vehicles and buses. It excludes central e-axles, e-motors mounted on the chassis that drive wheels through half-shafts, industrial robots and agricultural implements, and wheel-side reduction motors used in mining haul trucks.

The market splits in two. In volume terms, China's electric two-wheeler fleet and India's fast-growing electric scooter and rickshaw segments absorb tens of millions of outer-rotor hub motors each year at prices often below USD 60 per unit. In value terms, a single high-output car motor such as Protean Electric's Pm18 2500, rated at 220 kW and more than 2,500 Nm per wheel, can carry a price several hundred times higher. That mix shift explains why revenue grows at almost 12% a year while unit volumes rise far more slowly.

Passenger cars are the fastest-growing vehicle segment at a 31.75% CAGR from a small 2025 base, helped by the first European production car with in-wheel motors (the Renault 5 Turbo 3E) and Dongfeng's filing for a four-hub-motor version of its eπ 007 sedan in China. Axial flux designs are the fastest motor topology at 34.12%. Africa posts the fastest regional CAGR at 14.20% from a low base, while Asia Pacific (APAC) holds 67.40% of 2025 revenue.

The in-wheel motors market still faces real engineering doubts around unsprung mass, sealing and crash safety, and Radial Insights' forecast assumes car adoption stays below 1% of global light vehicle output through 2030 before scaling in the 2030s.

High-output car and axial flux segments expand three times faster than the hub motor core

Radial Insights splits the in-wheel motors market across five dimensions. Growth rates differ sharply because the mature two-wheeler hub motor business grows with scooter volumes, while car-grade motors are only now leaving the prototype stage. All figures below are CAGR values for 2025-2035.

By vehicle type: cars and vans grow fastest while two-wheelers keep the volume base

Electric two-wheelers and e-bikes remain the largest buyer group in 2025 because nearly every Chinese electric scooter and many Indian models use an outer-rotor hub motor in the rear wheel. Their 9.42% CAGR tracks unit growth in India, Southeast Asia and Africa, partly offset by steady price erosion in China. Electric three-wheelers grow at 10.86% as cargo and passenger rickshaws electrify across India, Bangladesh and East Africa. Passenger cars grow at 31.75% from a very small base: the Renault 5 Turbo 3E with Protean motors and Dongfeng's four-motor eπ 007 variant are the first real production programs. Light commercial vehicles grow at 24.38%, helped by van conversions; Protean shipped about one third of its roughly 1,500 motors last year to parent Bedeo for this use. Buses and heavy vehicles grow at 14.62% through low-floor city bus applications that value the flat floor a wheel motor allows.

By motor topology: axial flux leads on growth, outer-rotor direct-drive leads on volume

Outer-rotor direct-drive hub motors (9.18%) and geared hub motors (8.74%) serve scooters, e-bikes and three-wheelers, where cost per watt matters more than power density. Radial flux in-wheel motors (22.46%) are the incumbent car-grade design used by Protean and by Chinese suppliers such as Shanghai Automobile Electric Drive. Axial flux designs grow at 34.12% because their pancake shape fits inside a wheel with room left for a brake disc; Donut Lab showed a 21-inch, 88-pound unit rated at 845 hp at CES in January 2025, and Elaphe's Sonic.1 claims more than 5 kW/kg continuous power density.

By power output: units above 150 kW rise fastest as performance cars adopt the layout

Motors below 5 kW (9.05%) cover e-bikes and scooters. The 5 to 60 kW band (13.27%) serves three-wheelers, light quadricycles and small vans. The 60 to 150 kW band (27.83%) matches mainstream sedans such as Dongfeng's 100 kW per wheel layout. Units above 150 kW grow at 33.46% as performance programs such as the 555 hp Renault 5 Turbo 3E and Elaphe's 347 hp peak Sonic.1 move toward production.

By cooling method: liquid cooling scales with power density

Air-cooled motors (9.31%) dominate low-power two-wheelers because they are sealed, simple and cheap. Liquid-cooled motors grow at 26.94% because sustained car-level output inside a closed wheel needs active thermal management, which also raises the value per unit.

By sales channel: OEM fitment grows faster than retrofit kits

OEM fitment grows at 12.08% as carmakers and scooter brands design platforms around wheel motors. Retrofit and conversion grows at 10.67%, supported by e-bike conversion kits and commercial van electrification programs, but faces tighter type-approval checks in Europe and India.

Market Trends

Established carmakers, not start-ups, now lead in-wheel programs

Earlier four-hub-motor cars such as the Lightyear 0 and Lordstown Endurance came from start-ups that later failed. That pattern changed in 2025 and 2026. In November 2025, MIIT filing documents showed that Dongfeng plans a version of its eπ 007 sedan with four independent 100 kW in-wheel motors, 400 kW in total, supplied by Shanghai Automobile Electric Drive. In April 2026, Renault confirmed that the Renault 5 Turbo 3E will be the first European production car fitted with in-wheel motors, using Protean Electric hardware that delivers 555 hp to the rear wheels. Radial Insights treats these two programs as the start of commercial car demand.

Suppliers now claim cost parity with e-axles

Cost was the main barrier. In September 2025, Protean Electric said its latest ProteanDrive generation costs the same as conventional twin e-axle systems, citing fewer driveline parts, no half-shafts and simpler assembly. Dongfeng claims about 30% less mechanical loss, a 10% to 15% smaller turning radius and 20% to 30% lower maintenance costs for its hub-motor sedan. If those claims hold in fleet use, the in-wheel motors market could take share from twin-motor all-wheel-drive layouts in premium segments.

Axial flux and integrated-brake designs raise power density

At CES in January 2025, Elaphe Propulsion Technologies unveiled the Sonic.1, a front-wheel motor with integrated high-performance brakes, rated at 272 hp continuous and 347 hp peak per wheel, and used in scaled form on Italdesign's Quintessenza concept. At the same show, Donut Lab presented its Donut Motor family, from a 201 hp, 37-pound motorcycle unit already used by Verge Motorcycles to an 845 hp, 21-inch car unit. Integrating the brake inside the motor package addresses the main packaging objection to wheel motors on steered front axles.

Skateboard platforms are being designed around wheel motors

In December 2025, Donut Lab and WATT Electric Vehicle Company agreed to fit Donut in-wheel motors to WATT's PACES aluminum skateboard platform, with a prototype shown at CES 2026 and a four-wheel-drive version planned for later in 2026. Removing the central motor and half-shafts frees floor space for batteries or cargo, which is why delivery vans, buggies and low-volume sports cars are early targets.

Restraints and Challenges

Unsprung mass and ride quality

Placing 20 to 40 kg of motor in each wheel raises unsprung mass, which can degrade ride comfort and road holding unless suspension tuning compensates. Suppliers argue the effect is manageable, but carmakers still run long validation programs, which slows adoption. Radial Insights estimates that this concern alone shaves about 1.5 percentage points off the passenger car segment's potential CAGR.

Durability, sealing and crash safety

A wheel motor lives in water, salt, grit and pothole impacts. Bearings, seals and high-voltage connectors must survive 15 years of service, and crash rules require the motor to stay attached and electrically safe after a wheel strike. Few suppliers have fleet data at scale, and insurers and fleet buyers we interviewed asked for warranty terms longer than those offered for conventional e-axles.

Small supplier base and supplier failures

The car-grade supply base is thin, with Protean (about 120 employees), Elaphe, Donut Lab and a handful of Chinese firms. Bankruptcies of earlier in-wheel adopters such as Lightyear and Lordstown left carmakers cautious about single-source risk. Large tier-1 suppliers have mostly stayed with e-axles, limiting second-source options.

Softer EV demand in key markets

The International Energy Agency reported that global electric car sales fell by a bit over 8% year on year in the first quarter of 2026, linked to policy changes in the United States and China, even though it still expects about 23 million electric cars to be sold in 2026 (IEA Global EV Outlook 2026). Slower EV volumes delay new platform launches, and new platforms are where in-wheel motors get designed in.

Growth Drivers

Rapid EV volume growth widens the addressable base

The IEA reports that more than 20 million electric cars were sold worldwide in 2025, up 20% on 2024 and about one quarter of all new cars, and it expects about 23 million in 2026, close to 30% of the total. China produced nearly three quarters of the roughly 22 million electric cars made globally in 2025, and OICA data show Chinese new energy vehicle production of 16.63 million units, up 29%. Every new dedicated EV platform is a chance to design around wheel motors rather than central e-axles. Radial Insights estimates that a 1% shift of global EV output to in-wheel layouts would add roughly USD 1.1 Billion of annual revenue at current car-grade prices. We credit EV volume growth with about +2.4% of the market's annual growth through 2035.

Two- and three-wheeler electrification in Asia and Africa

Outer-rotor hub motors are the default drive for electric scooters, e-bikes and e-rickshaws because they remove the chain, gearbox and most service parts. OICA data show that Asia Pacific produced about 59.2 million motor vehicles in 2025, over 61% of world output, and India alone produced 6.49 million vehicles. Two-wheeler electrification in India, Indonesia, Vietnam and East Africa adds millions of hub motors each year, and Chinese suppliers such as Bafang Electric, QS Motor and Ananda Drive Techniques supply scooter makers such as Yadea and Jiangsu Xinri E-Vehicle and serve both domestic and export demand. Price per unit is low, but volume keeps the in-wheel motors market's base revenue growing; we estimate this driver contributes roughly 3.1 points of the overall 11.86% CAGR.

Packaging and control benefits for new vehicle architectures

Wheel motors free the space normally taken by a central motor, differential and half-shafts, which allows flatter floors, larger batteries and new body styles such as delivery vans with lower load floors and city buses with full-length low floors. Independent torque at each wheel enables torque vectoring with millisecond response, a point stressed by Donut Lab and WATT in December 2025, and supports advanced stability control and tighter turning. Dongfeng cites a 10% to 15% smaller turning radius and 25% more efficient regeneration for its four-motor sedan. As carmakers adopt skateboard and software-defined platforms, these benefits become easier to monetize. Radial Insights links this architecture shift to roughly +1.8 points of yearly market expansion, concentrated in the passenger car and light commercial vehicle segments.

Opportunities

Commercial van and bus retrofits

Protean's experience supplying about 500 motors a year to parent Bedeo for van conversions shows a path to revenue before mass car programs mature. Urban delivery fleets and low-floor bus builders in Europe and Turkey are natural buyers, and retrofit kits avoid the long design cycles of new car platforms.

Integrated wheel modules with brakes and steering

Suppliers that bundle motor, brake, bearing and later steer-by-wire actuators into one corner module can capture far more value per wheel. Elaphe's Sonic.1 with integrated brakes and Hyundai Mobis' long-running in-wheel research show the direction. Tire and wheel makers that co-design rims, bearings and motor housings also have an opening here.

Asia Pacific (APAC) holds two thirds of in-wheel motor revenue, while Europe leads car-grade adoption

Asia Pacific (APAC)

Asia Pacific (APAC) accounted for 67.40% of the in-wheel motors market in 2025, worth about USD 2,588.16 Million, and is forecast to reach USD 7,382.05 Million by 2035 at an 11.05% CAGR. China's electric two-wheeler industry is the core of this demand, and China also produced 16.63 million new energy vehicles in 2025, the base for Dongfeng's four-motor sedan. India adds fast-growing electric scooter and e-rickshaw volumes, with 6.49 million vehicles produced in 2025 according to OICA.

North America

North America represented 9.80% of 2025 revenue, about USD 376.32 Million, and is expected to reach USD 1,266.18 Million by 2035, a 12.90% CAGR. E-bike conversion kits and micromobility make up most current sales in North America, while the region's car programs remain at the prototype stage after the Lordstown Endurance program ended. Donut Lab and WATT used CES 2026 in Las Vegas to show their in-wheel skateboard platform to North American buyers.

Europe

Europe held a 15.60% share in 2025, worth about USD 599.04 Million, and is forecast to reach USD 2,182.12 Million by 2035, growing at 13.80% a year. Europe is the home of the leading car-grade suppliers, Protean Electric in the UK, Elaphe in Slovenia and Donut Lab in Finland, and of the first European production car with wheel motors, the Renault 5 Turbo 3E. European e-bike demand also supports a large hub motor aftermarket in Germany, the Netherlands and France.

Latin America

Latin America accounted for 3.10% of the in-wheel motors market in 2025, about USD 119.04 Million, rising to USD 383.14 Million by 2035 at a 12.40% CAGR. Brazil, Mexico and Colombia drive demand through electric scooters and delivery motorcycles, most of them imported from China with hub motors already fitted.

Middle East

The Middle East held 2.30% of 2025 revenue, about USD 88.32 Million, and is forecast to reach USD 302.47 Million by 2035 at a 13.10% CAGR. Turkey, where Protean has operations, plus electric bus and last-mile delivery programs in the Gulf states, account for most Middle East demand.

Africa

Africa represented 1.80% of the market in 2025, about USD 69.12 Million, and is set to reach USD 260.77 Million by 2035, the fastest regional CAGR at 14.20%. Electric motorcycle taxi programs in Kenya, Rwanda and Uganda use hub motors almost exclusively, and OICA reports that African new vehicle sales rose 22% in 2025 to 1.29 million units.

Car-grade in-wheel motors are a specialist race, while hub motors for two-wheelers are a scale business

The in-wheel motors market has two very different competitive layers. Car and van motors come from a small group of technology specialists that license designs, build pilot volumes and partner with carmakers. Two- and three-wheeler hub motors come from large Chinese and Indian manufacturers that compete on cost, scale and delivery. Few companies operate in both layers.

Car-grade technology specialists

Protean Electric, part of the Bedeo Group with sites in the UK, China and Turkey, is the most advanced car-grade supplier, holding more than 330 patents across 75 families and supplying the Renault 5 Turbo 3E. Elaphe Propulsion Technologies of Slovenia focuses on high-power motors with integrated brakes and works with design houses such as Italdesign. Donut Lab of Finland, which grew out of Verge Motorcycles, sells a modular axial flux motor range from drone scale to an 845 hp car motor and is pursuing platform deals such as the one with WATT.

Chinese drive system suppliers and carmakers

Shanghai Automobile Electric Drive supplies the four 100 kW motors in Dongfeng's eπ 007 hub-motor variant, and Dongfeng Motor itself has worked with Protean and with Weifu Group on earlier hub-drive vehicles. These players benefit from China's dense EV supply chain and from carmakers willing to try new layouts on limited-volume trims.

Two- and three-wheeler hub motor manufacturers

Bafang Electric (Suzhou) is a leading supplier of e-bike hub and mid-drive motors to European and North American bicycle brands. Jiangsu Xinri E-Vehicle and Yadea, two of China's largest electric scooter makers, source or build rear hub motors at very high volume. Ananda Drive Techniques serves e-bike OEMs, while QS Motor is known for high-power scooter and motorcycle hub motors sold worldwide.

Large automotive groups with in-wheel research

Hyundai Mobis has run an in-wheel drive program for years and publicly presented corner module concepts that combine motor, braking and steering. Schaeffler has shown wheel-hub drive concepts for urban vehicles. Their decision to industrialize, or not, will shape how fast the passenger car segment grows after 2030. Buyers we interviewed said a tier-1 entry would lower perceived supply risk more than any single performance gain.
