Wholesale Spoke Hub Motors for Electric Bicycle Conversion Kits

Spoke hub motors are among the products offered by Qianjiang Motor. As a Chinese motor manufacturer, we provide over 80 motor models including hub motors, mid-drive motors, and differential rear-axle motors, with support for OEM/ODM services and factory-direct pricing.

What is a Spoked Wheel Structure?

Spoked wheels feature a classic mechanical design that distinguishes them from solid alloy wheels; they utilize a composite structure consisting of high-strength steel spokes, a precision rim, and a reinforced hub. By distributing loads across multiple points, they deliver a combination of high toughness, superior impact resistance, and effective shock absorption. Compared to traditional one-piece wheels, spoked wheels offer key advantages—such as durability against rough terrain, repairability, fracture resistance, and exceptional adaptability—making them ideally suited for riding on complex, unpaved surfaces.

Key Advantages

1. Multi-point load distribution; impact-resistant and off-road capable

2. Tough and repairable; lower cost of ownership

3. Lightweight with low rolling resistance; saves energy and accelerates quickly

4. Comprehensive heat dissipation design; prevents blowouts and heat-induced performance loss

5. Rust-proof, corrosion-resistant, and durable; suitable for all weather conditions

6. Versatile retro aesthetic; highly compatible with custom modifications

Why Choose Qianjiang?

1. Selection of Premium Raw Materials

The rim of the spoke-style hub motor is formed from a single piece of high-strength virgin aluminum alloy, offering superior toughness, impact resistance, and resistance to deformation.

The spokes are crafted from 304 stainless steel using a precision wire-drawing process; they feature high tensile strength and resist stretching or snapping under sustained load, ensuring structural stability at the source.

2. Precision Tension Calibration

Utilizing a dual-calibration process combining manual and automated methods, spoke tension is kept uniform and consistent. This ensures precise dynamic balance, preventing wobbling or drifting at high speeds and eliminating common issues like rim eccentricity and instability.

3. Multi-Layer Anti-Corrosion Treatment

The rim surface undergoes a multi-stage treatment process, including polishing, sandblasting, anodizing, and high-temperature baking, to ensure excellent sealing and resistance to water, stains, and rust. This guarantees long-lasting aesthetic appeal and durability during extended outdoor use, without paint peeling or rusting.

4. Rigorous Factory Testing

Every wheel assembly undergoes five quality checks before leaving the factory: tension testing, dynamic balancing, static load testing, durability (bump) testing, and rust resistance testing. This eliminates defects such as runout, wobbling, or looseness, ensuring high product consistency suitable for mass-production vehicle assembly.

FAQ

Q: Are the spoked wheels prone to deformation or broken spokes?

A: The spokes manufactured by Qianjiang Motor use thickened 304 stainless steel and undergo precision tension tuning. They offer high tensile strength and even load distribution, making them resistant to deformation or breakage under normal loads or rough off-road conditions.

Q: What causes wobbling or pulling to one side while riding, and how can it be fixed?

A: Common causes include uneven spoke tension, localized looseness, slight rim runout, or improper tire mounting.

Solution: Regularly check spoke tightness and re-adjust tension evenly to restore stability. There is no need to replace the entire wheel; maintenance is simple and convenient.

Q: Can tubeless tires be installed? Are they compatible with both drum and disc brakes?

A: The entire product line supports both tube-type and tubeless tires, meeting standard installation requirements for tubeless tires.

They are compatible with both drum and disc brake systems and fit both front and rear wheels. They allow for direct installation without frame modifications, offering excellent versatility.

Q: Will they rust when used in rainy weather or on muddy roads?

A: The spokes are made of rust-resistant stainless steel, and the rims feature a multi-layer anti-corrosion baked finish. They are waterproof, rust-proof, and corrosion-resistant, making them suitable for long-term outdoor use in humid, muddy, or rainy conditions without easily rusting or oxidizing. They are designed for all-weather performance in demanding environments.

Q: Do you support customization for specific vehicle models and bulk supply?

A: We support customization for all electric and internal combustion vehicle models. We can tailor specifications based on frame parameters, axle diameters, hole spacing, and load requirements, catering to modified vehicles, custom builds, and mass production by OEMs.

We maintain ample stock of standard specifications and offer reliable customization lead times. We welcome inquiries regarding private-label production and long-term strategic partnerships.
