In e-bike assembly, the handlebar is more than a control point. It is where throttle response, cable routing and rider confidence meet. A grip base that does not lock down, or a cable clip that vibrates loose, can turn a well-built vehicle into a warranty issue. For distributors and assembly plants sourcing e-bike hardware, the real question is not whether a clamp ring looks right in a photo. It is whether every batch seats correctly, tightens evenly and arrives on schedule. Anhui Youliang Hardware Products Co., Ltd. builds its business around that question.
Five fastening components for e-bike handlebar and frame assembly
The company focuses on the small metal parts that hold a handlebar assembly together. Its product range covers five core categories: internally threaded aluminum rings, open U-type aluminum clamp rings, galvanized special-shaped clip brackets, black stamped metal clips and perforated aluminum rings. Product photos show polished silver rings with open U profiles and internal serrations, plus galvanized and black coated stamped brackets with dual mounting holes. Each category is produced for a specific job on the vehicle, not as a generic hardware item.
Internally threaded aluminum ring. Made from national-standard aluminum alloy and CNC turned, this ring uses precision internal threading and side positioning holes. Tight dimensional tolerances, rust resistance and wear resistance make it suitable for throttle grip base locking. It sleeves over and secures the throttle shaft on two-wheel electric motorcycles, leisure scooters and electric tricycles. Standard inner diameter options include 22 mm, 24 mm and 26 mm, with non-standard sizes available through custom mold development.
Open U-type aluminum clamp ring. This part is integrally formed from extruded aluminum alloy. The open elastic structure provides uniform clamping force, while the polished surface supports oxidation resistance. It works as an outer ring clamp for e-bike throttle grips, holding the grip in place and reducing loosening or slipping. Standard models fit common handlebar diameters such as 22 mm and 25 mm. Custom sizes are available for non-standard tubing.
Galvanized special-shaped clip bracket. Formed from cold-rolled steel plate with a hot-dip galvanized coating, this bracket is bent and stamped with dual-hole mounting positions. The galvanized finish supports corrosion and rust resistance. It is used for wire harness and brake cable fastening on handlebar stems and frame positions, keeping lines secure and reducing vibration. Left and right matching pairs are available for a range of domestic-standard frame mounting hole sizes.
Black stamped metal clips. These clips are stamped in one piece from cold-rolled iron plate and finished with black electrophoretic coating. The finish is wear-resistant and rust-proof, and the design includes reinforced rivet holes. Lug-type models serve as switch wiring harness fixing clamps. Window-type models act as throttle cable limiting clips. Both are widely used in domestic-standard e-bike and e-motorcycle assembly. Standard in-stock models and custom models are available, with hole spacing and curvature adjustable to customer drawings.
Perforated aluminum ring. This CNC-turned aluminum ring has precision internal threading, reserved side positioning holes and strict dimensional tolerance control. It provides wear resistance, rust resistance and high structural strength for throttle grip base locking and throttle shaft fixing. It is compatible with two-wheel electric motorcycles, leisure scooters and electric tricycles. Non-standard inner diameters, threads and side hole dimensions can be produced from customer drawings.
Manufacturing built for repeatable fit and flexible orders
Anhui Youliang Hardware Products Co., Ltd. is located in Lingbi County, Suzhou City, Anhui Province. It operates as an original manufacturer with automated CNC lathes and stamping production lines. The factory integrates independent mold development, raw material processing and finished product inspection under one operation. That structure matters for buyers because fit issues are rarely solved by a catalog alone. They are solved by controlling the tool, the material and the inspection step together.
The company supports OEM customization based on customer drawings or samples. It can handle small-batch sampling orders and large-volume procurement for complete vehicle assembly. Materials can be switched among aluminum, iron and stainless steel depending on the part and application. Dimensions, thread specifications, side hole positions, hole spacing and curvature can be adjusted on request. Fully automated production lines provide ample daily capacity for monthly bulk orders from assembly plants. The company operates a 1,000 m² self-owned factory.
Applications across e-bike, scooter and tricycle platforms
These components sit in high-contact areas where small failures become visible quickly. Throttle grip base rings lock the grip assembly to the shaft. Open U-type rings clamp the outer grip surface. Galvanized brackets route brake cables and wiring harnesses along the frame. Black stamped clips secure switch harnesses and limit throttle cable movement. Perforated rings add a machined locking option for grip bases. The parts are used on two-wheel electric motorcycles, leisure scooters, electric tricycles, domestic-standard e-bikes and e-motorcycles.
Why small fastening parts decide assembly quality
E-bike supply chains are cost-sensitive, but a loose clamp or a misaligned bracket can cost far more than the part itself. It can stop an assembly line, create a rework ticket or return a vehicle to the dealer. Buyers therefore compare more than unit price. They compare material grade, thread quality, coating adhesion, dimensional consistency and the supplier's ability to repeat the same fit across batches.
Standard sizes cover a large share of the market. Rings with 22 mm, 24 mm and 26 mm inner diameters, clamp rings for 22 mm and 25 mm handlebar tubes, and left/right bracket pairs for common frame holes give distributors practical stock options. Custom sizes keep new models moving when a frame opening, tube diameter or cable route changes. A supplier that can handle both standard stock and drawing-based customization reduces the number of vendors an assembly plant has to manage.
A specialist supplier with domestic and export experience
Domestically, Anhui Youliang supplies e-bike OEMs and accessory distributors, including brands such as Segway-Ninebot, AIMA, Yadea and TAILG. Internationally, its products are exported to Southeast Asia, the Middle East, Europe, America and other regions. The company's focus is narrow by design: e-bike handlebar aluminum rings, clamp fasteners and stamped hardware. That focus supports precise machining, reliable lead times and strong cost performance in a category where consistency is the product.
Request a sample or drawing-based quote
Send your handlebar tube diameter, thread specification, mounting hole pattern, material preference or a sample part. The team can review standard models and propose a custom tooling route for non-standard sizes. For overseas buyers, include target order volume and finish requirements so the quotation can be prepared accurately. Product samples and drawing reviews are the fastest way to confirm fit before production.
