Thru-Axle Hub Motors
-- Steady & Reliable Manufacturer --
The Modern Standard: High-Security Thru-Axle Hub Motors
The bicycle industry has rapidly adopted the thru-axle standard for its superior stiffness, enhanced safety, and precise wheel alignment, particularly in performance e-bikes, eMTBs, and high-end commuter models. Our Thru-Axle Hub Motors are a direct response to this evolution, designed to integrate flawlessly with modern frame and fork standards that utilize a bolt-through design instead of traditional quick-release skewers. This technology provides a significantly more secure and robust connection, crucial for handling the increased torque and speeds associated with electric assistance.
The critical engineering challenge in adapting a hub motor to a thru-axle is maintaining the structural integrity and precision of the motor axle assembly while accommodating various thru-axle diameters (e.g., 12mm, 15mm) and thread pitches. HENTACH solves this by utilizing a fixed inner axle, precision-machined from robust alloy steel, which is internally threaded or designed with specific end caps to allow the external thru-axle to pass through and clamp the wheel securely to the frame/fork dropouts. This results in a system that is incredibly strong, virtually eliminating the risk of axle slippage or dropout damage under extreme load, a common safety concern with high-power quick-release setups.
Enhanced Performance and Frame Stiffness
The stiffness provided by the thru-axle greatly benefits the overall e-bike performance. In rear-wheel applications, the increased stiffness minimizes flex in the swingarm area, leading to more direct power transfer and better handling, especially when cornering or climbing. For front thru-axle motors, it enhances steering precision and reduces brake rotor rub, which is vital for e-bikes utilizing high-performance hydraulic disc brakes. Our thru-axle motor design is optimized for this rigidity, ensuring that the motor's power is delivered efficiently without compromising the bike's dynamic characteristics.
These motors are overwhelmingly favored for use in high-end applications, including performance eMTBs, high-speed cargo bikes, and premium touring bikes—any application where structural integrity and maximum safety are paramount. We work closely with OEM partners to supply the exact drop-out widths (O.L.D.) and axle specifications required for their frame designs (e.g., 148mm Boost for eMTBs, or specialized widths for custom cargo frames). This customization includes the development of specific aluminum end caps (torque arms) that ensure perfect alignment and provide the necessary surface contact for safe, high-torque operation. Our B2B partnership includes engineering consultation to help clients select the precise motor winding and gear ratio that, when combined with the thru-axle rigidity, delivers the optimal power and speed profile for their intended market. By adopting HENTACH thru-axle hub motors, manufacturers are investing in a future-proof, high-performance drive system that meets the highest standards of safety and riding dynamics in the modern bicycle industry.
