Bicycle engine

The Nantong Jiali 1E40FA is a single-cylinder, air-cooled 2-stroke bicycle engine with a 38 mm bore and 40 mm stroke, yielding a displacement of 48 cc. This compact power unit is designed for bolt-on integration with standard bicycle frames, converting pedal cycles into motorized transport without altering the frame geometry. The engine's porting and combustion chamber are tuned for the low-RPM, high-torque demands of urban commuting rather than racing applications.

The cylinder is typically cast from aluminium alloy with a chrome-plated bore, a standard construction for small 2-stroke engines in this displacement class. Piston lubrication relies on premixed oil and petrol at ratios that buyers should confirm with the supplier, as premix specifications vary by market and emission regulation. Ignition is capacitor-discharge (CDI), typical for this engine family, with a pull-start recoil mechanism and centrifugal clutch that engages automatically as engine speed rises. The exhaust system uses a compact expansion chamber tuned to the 48 cc displacement, with mounting brackets that clamp to standard bicycle frame tubes.

Target buyers include bicycle conversion workshops, electric bike manufacturers seeking hybrid petrol-electric variants, and recreational vehicle builders in markets where 50 cc and below mopeds do not require full motorcycle licensing. The kit format implies inclusion of throttle, cable, fuel tank and mounting hardware, though exact contents should be verified per purchase order. Shipping terms of FOB and CIF are noted in the source; importers should confirm Incoterms, container load optimisation, and whether engines ship with or without attached exhaust systems to assess cubic metre efficiency.

Nantong Jiali Mechanical And Electrical Equipment Factory is located at No.18 Chengshan Road, Nantong 226006, Jiangsu Province, China. The supplier carries an imported tier classification and a harbor trust tier, which buyers should interpret as a baseline verification level rather than a guarantee of transaction security. The response rate is listed at 0.00 percent with zero average response hours, indicating that direct communication through the platform has not yet been established or recorded. Prospective buyers should plan for alternative contact methods and due diligence procedures.

The listing presents the factory as a source of 2-stroke bicycle engines, specifically the 1E40FA model for motorized bicycle conversions. No information is provided about factory floor space, annual output, employee count, R&D staff, or years in operation. ISO certification is mentioned in the source description, but no certificate numbers, accreditation bodies, or expiry dates are supplied. Buyers should request copies of ISO 9001 or equivalent certificates directly, along with any emission compliance documentation such as EURO II or EPA certificates that may be required for their destination market.
