Explore our premium range of light electric vehicles, performance carbon bikes, and versatile urban cruisers manufactured to the highest international compliance standards.
Analyzing the strategic shift from ground-up electric vehicle builds to highly customizable, eco-friendly e-bike retrofit kits.
The global micro-mobility industry is undergoing a seismic shift. As urban density increases and carbon-neutral targets loom closer, traditional transport infrastructures are proving inadequate. Electric bicycle conversion kits represent a critical bridge in this evolutionary cycle. Instead of forcing consumers and enterprise fleets to scrap high-value mechanical bicycles, conversion systems allow for the seamless integration of modern propulsion tech into existing frameworks.
From an environmental lifecycle perspective, retrofitting represents a massive net-positive in comparison to full-vehicle replacement. It reduces raw material consumption, saves energy that would otherwise be expended in frame fabrication, and extends the utility of high-end mechanical components. Manufacturers who recognize this potential are rapidly securing first-mover advantages in regions like Europe and North America, where e-bike adoption rates have skyrocketed.
Governments worldwide are accelerating micro-mobility infrastructure development. In the European Union, anti-dumping policies coupled with structural green transit subsidies have created a strong demand for reliable, European-compliant parts. In North America, the classification system of e-bikes (Class 1, 2, and 3) has created a complex array of regional demands that only agile manufacturers can satisfy through adaptable conversion systems.
Understanding the critical technologies underpinning modern conversion kits—from intelligent drive systems to energy-dense battery architectures.
Direct-drive and geared hub motor designs provide distinct operational envelopes. Geared hub motors offer high torque profiles ideal for city commuting and steep inclines, while direct-drive brushless motors offer long-term mechanical simplicity and regenerative braking functionality, capturing kinetic energy to feed back into the battery pack.
Integrating mid-drive conversion kits requires precision alignment with the bottom bracket shell. Unlike hub systems, mid-drives leverage the bike's mechanical gears, allowing for optimal power transfer. Our engineering roadmaps emphasize dual-sided torque sensors that dynamically regulate power output relative to rider cadence.
Modern conversion kits rely heavily on smart battery management systems (BMS). Using high-density 18650 and 21700 lithium-ion cells from Samsung and LG, our power packs incorporate active thermal regulation, short-circuit protection, and CAN-bus integration to monitor cell health and guarantee stable current discharge.
A look inside our advanced industrial manufacturing footprint, ensuring robust supply chains, rigorous quality control, and global delivery schedules.
Tianjin Evergreen Vehicle Co., Ltd. is a premier manufacturer and exporter of highly integrated electric conversion systems, custom frames, and complete electric-assist platforms. With over 30 years of industrial expertise, we design, engineer, and fabricate cutting-edge mobility systems. Located in Tianjin, the epicentre of precision light-vehicle manufacturing, we leverage unmatched access to high-grade raw materials, precision fabrication tooling, and an elite engineering talent pool.
We are a strategic vendor to major European postal systems, supermarket chains, and public transport operators. Our infrastructure features high-precision machinery, robotically welded frame jigs, and computerized battery analysis clusters. Our international manufacturing network spreads across China, South Korea, Taiwan, Poland, Portugal, Bulgaria, and Hungary, enabling us to sidestep supply chain disruptions and offer local, tax-optimized distribution corridors.
Our commitment to R&D ensures we stay at the cutting edge of electric mobility. By continuously upgrading our firmware protocols, refining thermal dissipation structures, and partnering with industry giants like Bafang, Shimano, and Samsung, we supply conversion kits that hold up to demanding operational profiles.
Through our comprehensive EU and US dealer network, we minimize delivery lead times and handle complex customs clearances. We supply critical components and complete configurations with speed, keeping our OEM/ODM distributors fully stocked throughout peak demand seasons.
Every single conversion component—from the hall sensors inside the hub to the aluminum battery brackets—undergoes systematic verification testing. We leverage state-of-the-art diagnostic instruments to check IP65 ingress protection, mechanical stress tolerances, and battery discharge curves under real-world temperature variations.
Evaluating how target industries customize e-bike conversion systems for varied geographic and business demands.
Global courier services utilize our high-torque mid-drive conversion kits on robust cargo bikes to traverse low-emission city centers. These configurations enable riders to transport heavy payloads through historic narrow passages without requiring costly commercial fleet licensing or diesel combustion permits.
Police divisions and municipal service workers use waterproof, high-power hub motor conversion kits for city patrols. The kits offer quiet acceleration and extended range. By deploying these systems on existing mechanical assets, municipalities save capital budgets and show solid green energy commitment.
Leisure resorts and historical city tour companies retrofit their bike assets with speed-limited pedal assist kits. This modernization lowers physical access barriers for tourists, allowing diverse user demographics to climb hilly terrain easily, which directly boosts rental cycle duration and revenue.
Exporting electric bicycle conversion kits into highly regulated markets demands rigorous compliance frameworks. Under the harmonized European standard EN15194-2017, pedelecs are limited to 250W continuous rated power and 25km/h motor-assist speeds. These units must also pass exhaustive electromagnetic compatibility (EMC) evaluations to prevent interference with other electronic equipment.
In the United States, conversion designs must align with UL 2849 and UN 38.3 safety guidelines, which cover the complete electrical drivetrain, charging systems, and battery packs. Working alongside premier verification agencies like TUV and SGS, we certify that our exports meet these strict requirements. Our systems proudly bear the CE, UL, ROHS, and REACH compliance marks.
A global footprint with localized technical backup, ensuring seamless operation for distributors, assemblers, and transit agencies.
Through our dedicated hubs in Germany, Belgium, Poland, and Hungary, we distribute spare parts, process warranty claims rapidly, and provide physical trial samples. This layout enables cost-efficient order replenishment and local support.
We work with distributors to design custom conversion components. From custom motor casing colors to custom wire routing and specific battery placement configurations, our engineers use advanced design software to match your market needs.
With operational hubs stretching across Asia, the Americas, and Oceania, we support logistics pathways that bypass regional bottlenecks. We assist with tax handling, tariff clearances, and final-mile distribution.
