PS-R11 Bottom Cover
PS-R11 Bottom Cover for e-bike motor mounting interfaces for brose, bosch, shimano, and customer platforms. Includes mapped product render, dimension drawing, asset status, engineering notes, and CAD request support.
Engineering Role
This motor-mount reference supports e-bike frame programs where motor interface position, bolt stack, stiffness, and service access must be controlled from drawing review through production inspection.
PS-R11 Bottom Cover is mapped from the PremFixer technical asset library with source reference 642-804-002MBK. The page keeps the render, drawing, and CAD status together so engineering and sourcing teams can review the item before sending a formal RFQ.

Dimensions & Interface Control
Use the mapped dimension drawing to confirm motor platform, bolt pattern, stack height, frame contact surface, and torque path. Final production dimensions should follow the customer drawing, mating component, assembly stack, and bicycle brand service requirement.
- Main image and dimension drawing are linked in the media panel for quick visual review.
- Confirm mating parts, frame material, coating stack, torque path, and service access before sampling.
- Custom length, profile, thread, hole position, finish, and packaging can be reviewed during RFQ.
Material, Process & Finish
| Material direction | Aluminum alloy, alloy steel, or drawing-specified material |
|---|---|
| Process direction | CNC machining, heat treatment, and drawing-based inspection |
| Finish options | Black anodizing, e-coating, plating, or customer finish |
Material and finish are selected against the drawing, corrosion target, weight requirement, and mating assembly. Alternative grades or coatings can be reviewed when the application needs higher strength, lower weight, better wear resistance, or a specific cosmetic target.
Quality & Traceability
PremFixer can support drawing-based inspection for hole position, flatness, thread gauges, profile, surface finish, and drawing-based dimensional report. Batch traceability, incoming material checks, coating reports, hardness checks, salt-spray validation, and dimensional reports can be prepared according to project requirements.
RFQ Data Checklist
- 2D drawing or marked sample photo for PS-R11.
- Target material, heat treatment, surface finish, and corrosion requirement.
- Assembly location, mating part, torque or load requirement, and annual volume.
- Packaging, labeling, inspection report, and CAD exchange format requirements.

Start RFQFrequently Asked Questions
Confirm fit, drawing control, finish options, and documentation before RFQ.
Q1 Which motor platforms does this mount support?
This motor mount supports BROSE, BOSCH, or SHIMANO mid-drive platforms. Confirm your motor model and frame interface before ordering.
Q2 Can I get custom mounting hole patterns?
Yes. Custom bolt patterns, thread sizes, and interface dimensions can be produced per your frame drawing. Submit a 2D drawing or STEP file for DFM review.
Q3 What material is used for e-bike motor mounts?
6061-T6 aluminum warm forged + CNC finished. Forging provides superior fatigue strength for the heavy-duty loads in e-bike motor mounting interfaces.
