At the heart of the new Dusty is TQ’s Harmonic Pin-Ring— a radical departure from conventional motor design that eliminates the friction and mechanical drag that plague other systems. Instead of a complex stack of gears bleeding power through each interface, the HPR60’s Harmonic Pin-Ring transmits force through a double tooth ring where multiple teeth engage simultaneously, achieving maximum surface pressure with minimum moving parts.
The result is direct, loss-free power transmission that lets the motor operate at far lower rotational speeds — quieter, smoother, and dramatically more efficient than anything else in its class.
MOTOR TQ HPR60
The result is direct, loss-free power transmission that lets the motor operate at far lower rotational speeds — quieter, smoother, and dramatically more efficient than anything else in its class.
What does this mean on the ride?
It means that when the HPR60 cuts assistance at 25 km/h, you don’t feel it. There’s no sudden wall, no sensation of dragging dead weight.
The motor disappears — and the bike simply keeps rolling, as naturally as if it were unpowered. Combined with the fact that both motor and battery are centrally positioned and perfectly balanced within the frame, weight distribution is optimized in a way that makes the Dusty feel lighter and more nimble than the numbers suggest. This is a bike that enhances your ride. It never hijacks it.
With 60 Nm of torque, 350 W of peak power, and up to 200% assistance, the HPR60 has all the power you’ll ever need — delivered exactly when you need it, in a package that weighs just 1.924 g and fits so neatly inside the Dusty’s architecture that you’d barely know it’s there.
THREE MODES. ENDLESS POSSIBILITIES.
The new Dusty runs on three fully customizable assistance levels, tuneable to your preferences via the TQ E-Bike App. After extensive real-world testing on the bike, the modes were calibrated specifically for the all-round riding style — designed to keep battery consumption low across everyday riding while unleashing full power when the terrain demands it.
• ECO: 102 W / 90% assistance*. The everyday mode. Efficient, smooth, and perfect for flatter terrain and longer adventures where you want to stretch every watt-hour to its limit.
• MID: 175 W / 125% assistance*. The all-day sweet spot. Enough power to take on rolling terrain and longer climbs without burning through your battery before lunch.
• HIGH: 350 W / 160% assistance*. Full send. Maximum peak power for steep climbs, technical sections, or those days when you just want the ride to be pure, reactive fun.
The TQ-HPR50 system comprises a very compact motor which we’ll talk about later on, a 360Wh removable internal battery located in the downtube, a 2” display fitted into the top tube and an optional 160Wh range extender. The whole system weighs in at 3.9Kg, 1850g the motor and 1830g the 360Wh battery. The optional TQ range extender weighs 950g.
Combining 3 natural-feeling levels of assistance and running almost silently, the TQ-HPR50 provides up to 300W of power and 50Nm of torque. A multitude of variables will always come into play when talking about range, but a rider of average weight (around 75Kg) can expect to be able to complete a ride of between 3-4 hours, with more than 1000m of altitude gain, switching between ECO and MID modes, and ride anywhere from 40 to 50km. The optional range extender can increase that by up to 50%.
COMPACT, LÉGER ET SILENCIEUX
Contrairement à la grande majorité des moteurs de vélos électriques sur le marché, le TQ-HPR50 utilise un système de transmission exclusif appelé “TQ Harmonic Pin-Ring”. Cette technologie révolutionnaire supprime les courroies et les engrenages présents dans d'autres modèles, garantissant ainsi une plus grande fiabilité et un niveau de bruit plus faible. Les mécanismes utilisés réduisent les frottements à des niveaux négligeables, garantissant une sensation de pédalage très similaire à celle d'une transmission de VTT conventionnelle, tout en étant le moteur le plus silencieux sur le marché aujourd'hui.
L'étendue des possibilités de réglage des paramètres du moteur TQ-HPR50 est l'une des caractéristiques qui correspond le mieux à notre philosophie chez Mondraker. L'application pour smartphone TQ E-Bike et la connexion Bluetooth vous permettent de contrôler tous les paramètres du moteur dans des proportions presque illimitées.
Trois modes sont proposés pour vous permettre de passer rapidement d'un niveau d'assistance à l'autre : ECO, MID et HIGH. Dans chacun de ces modes, vous disposez de 3 paramètres supplémentaires qui peuvent être réglés individuellement via l'application : Puissance maximale, Assistance et Temps de réponse au pédalage.
