Product Overview
This electric mountain bike is engineered for commercial distributors, regional brands, and fleet operators requiring a compliant, durable platform for trail and mixed-terrain applications. Built on a heat-treated 6061 aluminum alloy frame, it integrates a 48V removable lithium-ion battery system into the down tube, balancing structural rigidity with rapid battery swapping for fleet maintenance.
The powertrain features a 48V 500W high-torque rear hub motor (optional 250W EN15194-compliant variant for EU markets) paired with a 5-level pedal assist system (PAS) and a Shimano 21-speed drivetrain. Designed for OEM/ODM scalability, the frame structure, electrical harness, and branding locations support modular component selection and custom graphics to lower landing costs and simplify local inventory management.
Key Features
Down-Tube Semi-Integrated Removable Battery: The 48V 13Ah (624Wh) lithium pack features a dual-key anti-theft lock and off-bike charging capability. Sealed with IP65-rated silicone gaskets to protect against water jet ingress during rain or trail washes.
Hydroformed 6061-T6 Aluminum Frame: TIG-welded structural tubing undergoes T4 heat treatment for grain alignment followed by T6 artificial aging. Frame stress points are reinforced to support dynamic loads up to 120 kg without fatigue failure.
Modular Electrical Architecture: Uses quick-disconnect waterproof cable harnesses (IP67) at the handlebar junction, controller, and motor line. Reduces field maintenance time by allowing single-component swaps without re-threading internal cables.
Precision Drivetrain & Braking: Equipped with a Shimano Tourney 3x7 speed derailleur system and Tektro mechanical disc brakes with 160mm rotors. Brake levers include integrated motor cut-off sensors to immediately disengage power upon lever actuation.
Multi-Function LCD Console: Handlebar-mounted display provides real-time telemetry including speed, battery state of charge (voltage indicator), trip distance, assist mode (0–5), and error diagnostic codes for simplified technician troubleshooting.

FAQ
Q: What certifications are available for customs clearance in Europe and North America?
A: Complete documentation packages are provided per production batch, including CE certificates, EN15194:2017 test reports from accredited labs, UN38.3 transport safety test reports, MSDS, and UL2849 compliance files for North American imports.
Q: What is the Minimum Order Quantity (MOQ) and lead time for OEM orders?
A: Standard OEM MOQ is 50 units per color scheme. Sample production requires 15–20 days. Full container loads (20GP / 40HQ) carry a standard manufacturing lead time of 35–45 days following frame painting and component procurement verification.
Q: How does the factory manage quality control across frame welding and electrical assembly?
A: Frame structures undergo 100,000-cycle vibration fatigue testing before coating. Electrical assemblies pass incoming quality control (IQC) testing for battery BMS discharge cut-offs, motor torque consistency on dyno benches, and 100% full-vehicle functional testing prior to final packaging.
Q: What is the warranty policy and spare parts availability for bulk buyers?
A: Frames carry a 24-month structural warranty; motors, controllers, and battery packs are covered under a 12-month limited warranty. Orders include 1% free wear-and-tear spare parts (brake pads, cables, switches) alongside dedicated technical support for distributor service teams.
