The TQ HPR60 is a lightweight electric mountain bike motor engineered for integration into modern e-MTB systems. The motor provides up to 60 Nm of torque and 350 W peak power while maintaining a compact design at approximately 1.92 kg. It is developed using TQ’s Harmonic Pin-Ring transmission technology, which facilitates a reduction in mechanical complexity and contributes to a quiet operation as well as an immediate response during pedaling. This design approach aims to optimize the power-to-weight ratio to suit applications where minimal system weight and unobtrusive motor placement are critical requirements.
The HPR60 incorporates several enhancements over prior iterations, including a more efficient cooling system and the integration of a high-resolution display for monitoring key performance metrics. The motor’s design supports expanded battery options, allowing for greater flexibility in configuring overall powertrain systems for diverse e-MTB applications. Its compact form factor enables integration within the bottom bracket area, reducing interference with suspension dynamics and overall bike geometry. These technical modifications align with the goal of providing an advanced drive unit that meets the demands of lightweight electric mountain biking.
