Newly unveiled electric bike motor is ‘world’s lightest, most efficient’
TQ, the German force behind some of the lightest and quietest e-bike motors on the market, just took a leap forward – again. Barely weeks after debuting the lightweight HPR60 e-bike drive system, the company has introduced the HPR40, now claiming the title of the lightest and most efficient mid-drive motor in the world.
Tailored for road and gravel e-bikes, the HPR40 clocks in at just 1.17 kg (2.6 lb). That means it has slashed nearly half the weight of the previous HPR60, which weighed 1.92 kg (4.2 lb).
Despite being smaller, it still delivers a respectable 40 Nm of torque and up to 200W of peak power, making it ideal for riders seeking subtle assist rather than brute force. This isn’t about raw horsepower; it’s about efficiency and seamless integration.
Don’t expect to see it on the next 750W Lectric or Aventon, but look for it on higher-end gravel and road e-bikes where riders are looking for a modest boost instead of a powerful burst.
Unlike motors that have been rebadged from their original use on mountain bikes or commuters, TQ designed the HPR40 from scratch for lighter frames, aiming to remain nearly invisible on a bike’s bottom bracket and with controls hidden inside the handlebar. The result is a drive system that blends into the bike like a whisper, offering performance without the bulk.
At the heart of the HPR motor is TQ’s Harmonic Pin-Ring Transmission, which is a refined drivetrain rearranged to live fully inside a bike in place of the bottom bracket. This clever design eliminates noisy gears, reduces friction, and lets the motor engage instantly with zero lag. While that might sound like many mid-drives we regularly see from manufacturers like Bosch, TQ’s is so small and so deeply integrated that it’s barely visible to a casual observer.
The HPR40 pairs with a 290Wh battery that weighs just 1.46 kg (3.2 lb) and is hidden inside the downtube. There’s also a water bottle-sized 160 Wh range extender available, keeping total system weight under 2.7 kg (6 lbs). That’s one of the lightest fully integrated e-bike systems out there.
Control comes via a hidden handlebar remote hidden under the handlebar tape, and a sleek end-cap LED display keeps essentials in view without disrupting aesthetics. This stripped-down interface reinforces TQ’s philosophy: get out of the rider’s way. Or as New Atlas humorously described it, “it’s almost as if the company is daring riders to start a fresh round of mechanical doping scandals.”
TQ’s HPR40 isn’t just a fancy new drive system in a display booth, it’s already built into the new Canyon Endurace:ONFly, a sub‑10 kg (22 lb) e-road bike that tips the scales at just 9.9 kg. The Endurace:ONFly marries TQ’s whisper-soft assist with Canyon’s aerodynamic finesse, offering riders a bike that feels analog but rides electric.
The HPR40’s high torque density means riders can double their pedaling output with a modest 200 W boost. That translates to better climbs, longer rides, and a natural ride feel, all without the compromises of heavier systems. Considering that many riders can put out around 200W of constant power by themselves, the effect is like having a tandem rider along helping out, except that he only weighs 6 pounds.
The move shows that not every drive maker is merely chasing horsepower and torque figures. Instead, by merging elegant design, noticeable yet natural power, and light weight, TQ is proving that electric assistance doesn’t have to scream. It can whisper.
Electrek’s Take
Here’s the real story: the HPR40 isn’t just a technical footnote, it’s a signal. It shows that electric bike engineering is transitioning from brute force toward a future that also includes invisible, intuitive power systems. For riders chasing the delicate line between analog feel and electric assist, this is a breakthrough.
And considering that many riders are reaching an age where their mind wants to do the kind of rides that their body might no longer be capable of, systems like these can keep those riders in the saddle for longer. That’s many more years of keeping the good times rolling (and keeping the body young by continuing regular exercise).
Now the question is whether other brands will follow suit. Will we see this ultra-light motor trickle down into commuter e‑bikes or adventure-ready gravel rigs? If so, the day when an e‑bike feels exactly like a bike, but gives you a little assist when you need it most, just got much closer.
TQ is playing a long game: subtle, smart, and purpose-built. The HPR40 is merely the first move, and if this is any indicator, the next wave of e-bikes may feel less electric and more… old school?

The new and improved Hyundai IONIQ 5, or the hot-selling Chevy Equinox EV? Which electric SUV makes the smarter lease? Here’s the rundown.
Over 607,000 electric vehicles were sold in the US in the first half of 2025, thanks to some big discounts. Many automakers are currently offering generous savings, as Trump’s “One Big Beautiful Bill” is set to end federal EV incentives at the end of September.
According to Cox Automotive’s latest EV Market Monitor report, EV incentives reached a record of nearly $8,500 in June, or about 15% off the average transaction price (ATP).
That’s more than double the incentives offered on gas-powered vehicles. Seven electric vehicles had an ATP below $40,000, including the Chevy Equinox EV. The Equinox EV was the top-selling EV in the price range.
Starting at just $34,995, GM calls it “America’s most affordable 315+ range EV.” The electric Equinox has already propelled Chevy to become the number two EV brand in the US behind Tesla.
Through the first half of the year, the Chevy Equinox EV accounted for nearly a third of GM’s electric vehicle sales. And it could have sold even more. A dealer in California reached out to Electrek, claiming they had to wait over a month to receive Equinox EV models. It’s now on track to be among the top three selling EVs in the US.
Which EV to lease: Chevy Equinox EV or Hyundai IONIQ 5
With leases starting at just $289 per month, it’s no wonder the electric SUV is flying off the lot. The offer is for 24 months with $3,909 due at signing.
Alternatively, you can opt for 0% APR financing for 60 months, which Chevy is offering on all 2025 electric vehicle models.

Volkswagen’s ID.3 just got a gold star from the folks at ADAC, Europe’s largest automobile club. After four years of pushing the all-electric hatchback to its limits in a long-term endurance test, the VW ID.3’s battery still held 91% of its original capacity – a big win for EV durability.
Engineers at ADAC’s Test and Technology Centre in Landsberg am Lech, Germany, put the ID.3 Pro S through its paces, clocking over 160,000 kilometers (roughly 99,400 miles). That’s the full length of VW’s battery warranty – eight years or 160,000 km – and the car came out swinging.
The ID.3 Pro S is equipped with a 77 kWh net-capacity battery. Volkswagen guarantees that its ID. models will keep at least 70% of their original net battery capacity by the end of the warranty period. After the test, the ID.3 beat that benchmark by a long shot.
The ADAC didn’t baby this car, either. Over 40% of the charging was done using DC fast chargers, and the vehicle was frequently left at 100% charge between test drives, sometimes for days at a time. (That’s a no-no for battery longevity, but it’s precisely why this test matters.)
Engineers kept a close eye on the ID.3’s battery health between drives. They also regularly updated the vehicle software, including installing Volkswagen’s EV Route Planner, which calculates optimal charging stops using real-time traffic and charge level data. One major update even bumped up the charging rate to 170 kW.
The software upgrades didn’t just improve charging – they helped boost efficiency too, especially over short distances and during chilly winter temps (0–5C/32–41F).
Beyond battery life, the VW ID.3 also scored high marks for build quality. Even after all those kilometers, ADAC said the chassis, suspension, steering, and body were still in solid shape – no significant wear or issues.
ADAC’s big piece of advice is to keep your software up to date. That made a noticeable difference in range and driving experience over the four-year test.
Martin Sander, a Volkswagen board of management member responsible for sales, marketing and after sales, says the results show its ID. line (including the US-made ID.4s) is built to last. “A high battery capacity of over 90% after 160,000 kilometers confirms our ID. models are also very attractive as used cars and continue to meet the requirements of our customers.”
