Learn MoreMexico City (CDMX) is currently undergoing one of the most critical environmental and transportation transformations in Latin America. With a metropolitan area housing over 22 million residents, the local government has placed strict mandates on carbon emissions, pushing for rapid fleet electrification. However, purchasing brand-new electric buses, delivery vans, and heavy-duty trucks involves massive capital expenditure. This economic barrier has catalyzed a high demand for in-wheel electric motor car conversion kits in Mexico City.
By utilizing advanced permanent magnet synchronous motors (PMSM) and integrated e-axles, fleet operators in Mexico City can convert their existing internal combustion engine (ICE) fleets into zero-emission electric vehicles. This retrofitting strategy bypasses the steep acquisition costs of new EVs while utilizing the robust, functional chassis of existing commercial fleets.
In-wheel motor technology eliminates traditional mechanical transmission components, saving valuable chassis space for batteries, which is critical for navigating Mexico City's heavily congested arterial roads.
Retrofitting with high-efficiency PMSM motors allows commercial vehicles to bypass the "Hoy No Circula" restrictions, permitting 24/7 logistics and passenger transit operations.
Creating an integrated solution for electric vehicle drive platforms that meet various usage needs in urban and industrial environments.






The implementation of in-wheel electric motor car conversion kits in Mexico City addresses several key localized application scenarios:
Thousands of microbuses (colectivos) serve as the backbone of CDMX public transit. Converting these high-mileage diesel and gasoline passenger vans into electric vehicles using our 60KW to 120KW PMSM motors drastically reduces the city's particulate matter emissions. In-wheel systems allow transit operators to retain passenger cabin space while converting the drivetrain efficiently.
Logistics giants operating in areas like the Centro Histórico face narrow streets, heavy traffic, and strict idling rules. Integrating 130/286kW Integrated e-Axles or compact in-wheel motor kits into 4.5T logistics trucks guarantees high low-end torque, regenerative braking to recover energy in stop-and-go traffic, and silent nighttime deliveries.
Mexico City's government is prioritizing the greening of public works. Sanitation trucks, which operate on fixed routes with high stop-start frequencies, are perfect candidates for e-Axle conversions. Pumbaa’s central and integrated e-axles provide the high-torque, heavy-duty durability needed to support waste management operations without producing tailpipe emissions.

Mexico City sits at an elevation of 2,240 meters above sea level. This high altitude presents a unique challenge for traditional internal combustion engines, which experience a significant drop in oxygen levels, leading to incomplete combustion, power loss, and increased emissions.
Electric vehicle drivetrains, particularly Pumbaa's Permanent Magnet Synchronous Motors (PMSM), are completely unaffected by altitude. They deliver 100% torque instantly, regardless of elevation or air density. By converting fleet vehicles with our in-wheel electric motor kits, operators in CDMX experience consistent, high-efficiency power output. Additionally, our advanced liquid cooling and thermal management systems prevent overheating during long climbs up the valley basin surrounding the city.
Furthermore, our integrated Motor Controller Units (MCU) and Vehicle Control Units (VCU) utilize SVPWM modulation and space vector control strategies to optimize energy usage, allowing converted vehicles to achieve up to 10% higher energy efficiency than standard industry drivetrains.

Hear from our global partners and fleet operators who have successfully integrated Pumbaa E-Drive systems.
"We used to source motors globally, but those suppliers rarely allowed any design modifications. Working with PUMBAA has completely changed that. I can request various custom design changes based on project needs—whether for their Permanent Magnet Synchronous Motors (PMSM), Motor Controller Units (MCU), or Integrated E-Axles—they always accurately understand our drawings and deliver on time. The product precision is extremely high, fully meeting our specifications."
"Doing business with PUMBAA is seamless. When we encounter technical challenges—whether during the integration of their Central E-Axle into our logistics vehicles or fine-tuning the Motor Controller Unit (MCU) for optimal performance—their engineering team provides precise, clear solutions faster than we anticipate. They don't just sell components; they provide a holistic electric drive platform solution."
Our partner in China is a consortium of leading OEMs, including Sany, Zoomlion, Jiangling, Chery, China CNR, Ruichi, Chang'an, JAC, Dongfeng, and Jinlong.
