Your drawing is the blueprint. We machine it to spec, then verify every critical dimension before the parts leave our floor. No guesswork, no surprises.
We are BQUQ, a precision manufacturing factory in Dongguan, China, with 20 years in CNC machining, metal stamping, springs, and heat sinks. For bicycle parts, we cut aluminum from 6061-T6 or 7075-T6, hold tolerances to ±0.01 mm, and ship in 7–15 days.
Tolerance: ±0.01 mm (ISO 2768-fine)
Lead time: 7–15 days for prototypes, 15–25 days for production
No MOQ: order one piece or ten thousand
Inspection: full dimensional report with every batch
Specifications
We run a mix of 3-axis, 4-axis, and 5-axis CNC mills, plus CNC lathes for round parts. All machines are calibrated weekly. Raw material is sourced with mill certificates, and we keep stock for common aluminum grades.
For bicycle parts, we commonly machine: dropouts, derailleur hangers, brake mounts, stem clamps, seatpost collars, and crank arms. Wall thickness down to 1.5 mm is routine, but we confirm stiffness with FEA if you request it.
Three reasons buyers send us their drawings
1. Batch-traceable quality
Every part gets a unique batch number. We record raw material heat number, machine used, operator, and inspection results. If a problem shows up in the field, we trace it back to the exact batch and correct the process. No vague "we checked it."
2. Inspection report per batch
You get a full dimensional report with each shipment. Critical features are measured on a CMM, and we include the data sheet. For high-volume runs, we use SPC sampling—every 20th piece checked. You know exactly what you received, not what we hope we made.
3. One factory for CNC + stamping + springs + heat sinks
Your bicycle part might need a CNC-machined bracket, a stamped washer, a spring clip, and a heat sink for a motor controller. We make all four in-house. One purchase order, one quality system, one shipping point. You avoid juggling four suppliers and four sets of delays.
Where these parts are used
CNC machined aluminum bicycle parts go into performance and electric bikes, where strength-to-weight ratio and precision matter.
Derailleur hangers – must align perfectly with the cassette; ±0.01 mm keeps shifting crisp.
Brake caliper mounts – flatness and thread alignment prevent brake rub and pad wear.
Stem and handlebar clamps – fatigue resistance is critical; 7075-T6 with smooth surface finish avoids stress risers.
Motor mounts for e-bikes – need tight tolerances to align the motor axle with the frame dropouts.
Suspension linkage parts – drilled and reamed holes for pivot pins; bushing fit is everything.
Custom adapters – for converting frames, mounting racks, or fitting non-standard components.
We also machine prototypes for frame builders and small-series production for boutique bike brands. If it’s aluminum and it’s on a bike, we can cut it.
Questions buyers ask before ordering
Q: Do you really have no MOQ?
A: Yes. We run one-off prototypes for fit testing and full production runs. Setup cost is quoted separately for small batches, but the unit price drops as quantity increases. No minimum order, no forced inventory.
Q: How do you guarantee tolerance and quality?
A: We inspect 100% of critical dimensions on every part for batches under 500 pieces. For larger runs, we use SPC sampling with AQL 1.0. A CMM report is included with every shipment. If a part is out of spec, we replace it at no cost.
Q: What is your typical lead time?
A: Prototypes: 7–10 days after drawing approval. Production: 15–25 days, depending on quantity and surface treatment. Anodizing adds 3–5 days. We quote exact dates when you send the drawing.
Q: Can you provide material certificates?
A: Yes. Every batch comes with a mill certificate for the aluminum, plus RoHS and REACH compliance documents if needed. We also keep samples of raw material for 12 months after shipment.
