TQ HPR60 2026: New Motor for Lightweight E-Bikes with More Power and Torque, Same Light Weight
Introduction:
The e-MTB motor sector has seen significant evolution, with increasing focus on combining compact size and low weight. TQ, a leading company in the field, introduced the HPR50 drive system in 2022. This innovation enabled the development of a new generation of lightweight e-bikes, such as the Trek Fuel EXe. Now, TQ is launching the new HPR60 drive system, building on its predecessor's success and promising improvements in torque, power, cooling, display, and battery options.
TQ HPR60 Features:
The TQ HPR60 system maintains the compact size and low weight of the HPR50, making it easier to integrate into bike frames without compromising suspension design. The HPR60 motor weighs 1.92 kg, only about 70 grams more than the HPR50, yet it offers a 20% increase in torque and a 17% boost in peak power. With up to 60 Nm of torque and 350 W of peak power, TQ claims the HPR60 has the highest torque density among drive systems on the market.
Key TQ HPR60 Upgrades Compared to HPR50:
Increased Torque: +10 Nm of torque, a 20% increase.
Increased Motor Power: +50 W of power, a 17% increase.
Improved Cooling: Optimized cooling concept for higher thermal stability.
Increased Efficiency: Greater operational efficiency.
Reduced Noise Emissions: Lower noise for quieter operation.
High-Resolution Display: High-resolution color display with extended functions.
New Battery Options: Available with 290 Wh and 580 Wh batteries.
Harmonic Pin-Ring (HPR) Transmission Technology:
Like the HPR50, the HPR60 utilizes TQ's Harmonic Pin-Ring (HPR) Transmission technology, developed from decades of experience in engineering electric motors for robots, satellites, and spacecraft. This technology employs two spline rings that interface, with a single reduction stage, resulting in a system with fewer parts, smaller dimensions, and lighter weight compared to traditional gear systems. The motor is integrated concentrically with the bottom bracket, surrounding the crank spindle. This configuration contributes to quiet operation, with instant response and a natural, drag-free pedaling feel. The HPR60 features three pedal assist modes, customizable via the TQ app. Its Q-factor of just 135 mm offers a stance width comparable to traditional bicycles.
Expanded Battery Options:
Unlike the HPR50, which only offered a single 360 Wh battery, the HPR60 is compatible with three different battery sizes: 290 Wh, 360 Wh, and 580 Wh. TQ states these batteries offer the best weight-to-capacity ratio in their class, thanks to the highest energy density on the market. The HPR60 motor system with the 290 Wh battery (plus remote and display) is claimed to be the lightest e-bike system in its category, weighing just 3.53 kg. With compact dimensions and estimated weights of 1.46 kg (290 Wh), 1.83 kg (360 Wh), and 2.70 kg (580 Wh), these batteries should enable manufacturers to create bikes that look and feel more like analog bikes. For extended range, an optional 160 Wh range extender is available, weighing 960 grams, and is the size of a 500 ml water bottle, attaching via a Fidlock mount or certified bottle holders.
New Display and Remote:
TQ's new 2-inch O-LED full-color display is designed for seamless integration into the bike's top tube, offering protection and optimal visibility in all lighting conditions. The display shows essential ride information and also serves as the system's power on/off button. Riders can connect to the system via the TQ app, and it's compatible with all ANT+ bike computers.
The HPR60 remote has a low-profile design, similar to the existing HPR50 remote. It mounts discreetly on the handlebar next to the left grip with a simple, easy-to-use button layout. Unlike some wired remotes, the TQ remote can be unplugged from its cable, which should simplify bar swaps or component changes.
TQ-HPR60 Equipped Bikes:
The TQ-HPR60 is launching today, and several new lightweight e-bike models featuring this drive system are expected soon. One of the first announced models is the new Yeti MTe lightweight e-bike, an addition to Yeti's lineup with 145 mm of rear travel paired with a 160 mm fork. TQ has previously partnered with brands like Trek, Scott, Rotwild, UNNO, BMC, and Canyon to produce various lightweight e-MTB, e-road, and e-gravel models. More HPR60-equipped e-bike models are anticipated to be announced in the near future.
