도심 통근용 전기자전거 프레임 제조업체

The TDF45L is engineered with a versatile motor interface. It is designed to be compatible with popular mid-drive motor systems (such as Bafang M-series, Shimano STEPS, or others upon request) as well as rear-hub motor configurations. During the OEM development phase, we can adjust the motor bracket interface to match your specific drive system requirements perfectly.

Our Smooth Weld Technology involves a refined double-pass welding process followed by precision hand-polishing. This eliminates the visible “coin-stack” weld beads typically found on standard frames, giving the TDF45L a seamless, premium carbon-like aesthetic. This high-end finish significantly enhances the visual value of your final product in the retail market.

Yes, the urban commuter ebike frame features a “Sleek Integrated Design” specifically engineered for downtube-integrated batteries. It supports various capacity options while maintaining structural rigidity. The design ensures the battery is secure, protected from elements, and easily accessible for charging or removal, contributing to the modern, minimalist look of the bike.

Absolutely. While the standard urban commuter ebike frame features our optimized “Urban Comfort Geometry” for an upright riding position, as an OEM/ODM partner, JOBO can adjust geometry parameters or offer both Step-through and Step-over variations to suit your specific target market and regional sizing needs.

The TDF45L is designed for responsive city handling and typically supports standard 700c (28") or 27.5" wheels. The frame provides ample clearance for wider urban tires (e.g., up to 50mm or 2.0"), allowing for added comfort and puncture protection on uneven city streets.

Yes, the urban commuter ebike frame is “Commuter-Ready.” It comes equipped with standardized, reinforced mounting points for full-coverage fenders, heavy-duty rear cargo racks, and kickstands. We can also integrate internal routing channels for hard-wired lighting systems, ensuring your bike is practical and ready for daily transportation right out of the box.

We use high-grade 6061 aluminum alloy and employ advanced T6 heat treatment processes to ensure maximum strength and fatigue resistance. Every batch undergoes rigorous ISO-standard testing, including vibration and impact tests, to guarantee the frame can withstand the rigors of daily commuting and high-mileage usage.

Lead times vary based on order volume and customization levels (e.g., painting and decal requirements). Generally, once the sample is approved, mass production lead time ranges from 45 to 60 days. JOBO prides itself on “mass production consistency” and supply chain stability to help you meet your market launch schedules.
