The newly revealed electric bicycle engine is “the lightest in the world, the most effective”

TQ, the German strength behind some of the lightest and quietest electric bike engines on the market, just leap forward – Again. As soon as weeks after launching the Légé HPR60 bicycle driving system, the company has introduced HPR40, now affirming the most light and most effective engine title in the world.

Captured for electric bikes on the road and gravel, the HPR40 goes to only 1.17 kg (2.6 lb). This means that it reduced almost half of the weight of the previous HPR60, which weighed 1.92 kg (4.2 lb).

Although it is smaller, it always offers a respectable 40 nm of torque and up to 200 W of advanced power, which makes it ideal for cyclists looking for subtle assistance rather than brute force. It is not a question of raw power; This is transparent efficiency and integration.

Do not expect to see him in the next 750W LECTRIC or AVENTONBut look for it High -end gravel and electric road bikes Where the runners are looking for a modest boost instead of a powerful burst.

Unlike the engines that have been rebounded in their original use on mountain bikes or shuttlers, TQ designed the HPR40 from zero for lighter frames, aimed at remaining almost invisible on the bike bottom support and with hidden controls inside the handlebars. The result is a training system that blends into the bicycle as a whisper, offering performance without most.

At the heart of the HPR engine is the Harmonic TQ harmonic transmission, which is a reorganized refined transmission to live completely inside a bicycle instead of the lower support. This intelligent design eliminates noisy gears, reduces friction and allows the engine to join instantly with zero shift. Although it may look like many mid-term walks that we see regularly manufacturers like BoschTQ is so small and so deeply integrated that it is barely visible for an occasional observer.

The HPR40 goes with a 290Wh battery which weighs only 1.46 kg (3.2 lb) and is hidden inside the bottom tube. There is also an extension of the 160 Wh Water Bottle range, keeping the total weight of the system less than 2.7 kg (6 lb). It is one of the most lightly integrated electric bike systems.

The control passes via a handlebar remote control hidden under the handlebar ribbon, and an elegant LED screen at the end of the capital maintains the essential elements without disturbing the aesthetics. This stripped interface reinforces the philosophy of TQ: Get out of the rider path. Or like New atlas Describes him with humor: “It is almost as if the company audoyed the runners to start a new series of mechanical doping scandals.”

The TQ HPR40 is not only a new sophisticated driving system in a display cabin, it is already integrated into the new Endurace canyon bike: Onfly, an electronic bike of less than 10 kg (22 lb) which tips the scale at only 9.9 kg. The Endurace: Onfly marries the assistance to TQ whispers with the aerodynamic finesse of Canyon, offering runners a bicycle that feels analog but which rolls electric.

The high torque density of HPR40 means that cyclists can double their pedaling outing with a modest boost of 200 W. This results in better climbs, longer rides and a feeling of natural driving, all without the compromises of heavier systems. Since many cyclists can extinguish about 200 W of constant power by themselves, the effect is like having a rider in tandem while helping, except that he weighs only 6 pounds.

This decision shows that all the manufacturers of the reader do not simply hunt the power and torque figures. Instead, by merging an elegant design, a notable but natural power and a light weight, TQ proves that electric aid does not have to shout. He can whisper.

Electrek taking

Here is the real story: the HPR40 is not only a low page note, it is a signal. It shows that electric bike engineering goes from brute force to a future which also includes invisible and intuitive food systems. For cyclists who run the delicate line between the analog sensation and electrical assistance, it is a breakthrough.

And considering that many runners reach an age when their mind wants to make the type of rides that their body may no longer be capable of, systems like these can keep these runners in the saddle longer. It has been years to keep the right times (and keep the body young by pursuing a regular exercise).

Now the question is whether other brands will follow. Will we see this ultra-light engine runoff in suburban DIYs or gravel platforms ready for adventure? If this is the case, the day an e-bike feels Exactly Like a bicycle, but gives you a little help when you need it most, you get very close.

TQ plays a long game: subtle, intelligent and specially designed. The HPR40 is only the first time, and if it is an indicator, the next wave of electric bikes can feel less electric and more … Old School?
