TQ HPR — the ultra-light harmonic-drive family
TQ (Technische Qualität, Germany) has been producing harmonic pin-ring drive motors since 2022. Three variants coexist in 2026:
- TQ HPR50 (2022, still in production) — 50 Nm rated (approx. 38 Nm measured in practice) / 300 W / 1.85 kg. Q-factor 135 mm: the narrowest on the market. IP67. Used on Trek Fuel EX-e, Scott Lumen, Pinarello Nytro, BMC Fourstroke AMP. Tuning kits available: SpeedBox 3.1, SpeedFun Furious/Ribelle, PearTune MSO TQ, bikespeed RS.
- TQ HPR60 (June 2025) — 60 Nm / 350 W / 1.92 kg. Direct successor to the HPR50 on new model lines. Fitted to Trek Fuel+ 2026, Yeti MTe, Scott Solace eRide, Propain, Norco. Compatible with SpeedBox 3.1 and PearTune MSO TQ. PearTune has confirmed HPR60 support on its 2026 roadmap.
- TQ HPR40 (June 2025) — 40 Nm / 200 W / 1.17 kg. Ultra-light road and gravel motor. Found on Canyon Endurace:ONfly and Orbea Rallon RS. No confirmed internal kit is available for the HPR40 — the BadassBox 4 is the only option, and only on bikes with an external rear wheel speed sensor.
The TQ family is known for its near-silent operation and minimal Q-factor — at the cost of lower peak assistance compared to Bosch or Yamaha. A tuning kit does not change the motor torque output; it only removes the assistance cut-off, allowing the motor to keep assisting at higher speeds for off-road riding.
ZF CentriX — automotive group enters the mid-drive market
Announced at Eurobike 2024, the ZF CentriX uses a 48 V harmonic (strain-wave) drive system and is available in two versions: CentriX 90 (90 Nm) and CentriX 75 (75 Nm), both weighing around 2.5 kg. ZF (a major German automotive supplier) provides a complete ecosystem including display, battery, and connectivity. The first production bike is the Raymon Tarok Ultra; Riese & Müller has adopted the CentriX 90 on its flagship models for 2026.
No dedicated internal tuning kit exists for the ZF CentriX as of mid-2026. The BadassBox 4 remains the only viable option, contingent on the specific bike having an external rear wheel speed sensor. Check your model's specification before purchasing.
Fazua Ride 60 — discontinued May 2026
The Fazua Ride 60 (60 Nm / 450 W peak / 1.96 kg) was fitted to premium lightweight road and trail ebikes: Trek Domane+, Orbea Gain, Cannondale Topstone Neo SL, Pinarello Dyodo, and Focus Paralane2. Its distinctive feature was the removable Drivepack system, allowing the motor and battery unit to be extracted for riding without electric assistance. Existing tuning kits for the Ride 60 platform continue to function on bikes already in circulation.
No kit for your motor? The universal fallback
If your motor does not appear in the table above, the BadassBox 4 is the default universal solution. It works on any ebike with an external rear wheel speed sensor — which covers the overwhelming majority of models on the market. It operates without any electronic contact with the motor, leaving no traces. Installation takes around 15 minutes with no tools required.
The trade-off: the console displays half your actual speed. The free Boost Buddy app (iOS/Android) shows the real figure via Bluetooth.
