In the booming world of electric bikes, there’s an ongoing debate – torque sensors or cadence sensors? If you’re new to the scene or even a seasoned e-bike enthusiast, understanding the difference between the two can help optimize your riding experience and bang-for-your-buck. Let’s dive into the mechanics and merits of each to help you make an informed decision.

The difference between torque and cadence sensors

First let’s start with the basics. Both torque sensors and cadence sensors are methods used to activate pedal assist on an e-bike. When the rider pedals, the sensor reads that pedaling input and tells the e-bike’s speed controller to apply power to the motor. The major difference is just how the sensor reads that input, and that difference has a big effect on the e-bike’s performance.

Cadence sensors: These sensors detect the speed at which you’re pedaling. They don’t know or care how hard you’re pedaling, just how fast. Once you achieve a specific pedaling speed, they generally tell the motor to start working, providing a predetermined level of assistance. On most e-bikes with a cadence sensor, that means the assist is more of a binary system: The motor is either on or off, based on your pedaling speed. There is usually some lag time between when the pedaling begins and when the motor kicks in, which is caused by the cadence sensor waiting to see how many sensor magnets pass by in a given time period. Some e-bike companies have been able to program in slightly more refined cadence sensor-based pedal assist, such as Lectric eBikes. But at their core, cadence sensors are still a very simpler option that results in more of an off/on motor activation feel to the ride.

Torque sensors: Torque sensors, on the other hand, measure the force you apply to the pedals. They aren’t as interested in the speed of your pedaling, but rather the strength of your pedaling. The harder you pedal, the more assistance they will tell the motor to provide, making the e-bike experience feel more intuitive and akin to traditional biking. This sensor essentially gauges the tension in the bike’s drivetrain, either at the pedals or along the chain line, and adjusts the electric assist proportionally. The more effort you exert, the more boost you get. There’s also very minimal lag between the time a rider starts pedaling and the time that the assist kicks in.

The difference in the riding experience

Cadence sensors: For those who prefer a lower price tag, cadence sensors are the way to go. They’re particularly useful for riders who may not want to or be able to exert too much force, like those with certain physical limitations or those who simply prefer a more predictable, cruise-control type of ride. However, this can sometimes lead to an abrupt start, especially if you’re pedaling fast from a stationary position. The lag time of 1-2 seconds can also be a pain, especially when the bike is in high gear or riders are starting up a hill, since the familiar electric assist is absent at start. Lastly, cadence sensors can make it hard to ride in a group unless everyone is on the same type of e-bike and in the same power level. This is because each power level usually brings riders up to set speed, such as 5 mph for level 1, 8 mph for level 2, and so on.

Torque sensors: E-bikes with torque sensors often feel more “natural” to traditional cyclists and newcomers alike. The intuitive relationship between your effort and the motor’s output makes for a smoother transition between power levels, offering a ride that closely mirrors the experience of riding a non-electric bicycle (just with less sweat). It provides a greater sense of control over the bike’s power and speed, especially beneficial for tackling varying terrains. Climbing a steep hill? Push harder, and the bike responds in kind. It feels more like the bike’s power is an extension of your own power, as opposed to cadence sensor e-bikes which feel more like an e-bike on cruise control.

A hybrid approach

The comparison of pure cadence vs torque sensor pedal assist is really only applicable on most hub motor e-bikes. Many e-bikes with a mid-drive motor will actually use multiple sensors, including a combination of cadence and torque sensors, as well as other sensors such as an angle sensor to help increase power on hill climbs.

The hybrid approach used on most mid-drive e-bikes is helpful because the torque sensor can be used to give nearly instant feedback and intuitive power selection, while the cadence sensor provides added information, such as if the rider is downshifting and thus pedaling at a much higher speed (likely indicating a hill).

My personal preference

I’ve been riding e-bikes for nearly 15 years and have thrown a leg over several hundred different models. While any e-bike will work for most people, the two different styles of pedal assist sensors definitely make a big difference.

For me, I prefer a torque sensor on any e-bike that I’m riding either for fitness or the actual pedaling experience (like joy rides through nature when I want to go slow and enjoy the surroundings). Unlike a cadence sensor, a torque sensor gives me more predictable and intuitive pedal assist that doesn’t rocket me up to higher speeds when I start pedaling, but instead feels more like it “checks in” with me to find the appropriate power and speed for the motor assist.

However, torque sensors can often add a few hundred dollars to the price tag of a bike, and thus when I’m looking for a budget e-bike, I know that I can make do with slightly less intuitive pedal assist as a trade off for saving some serious cash. And of course on any e-bike that is used for mostly throttle-only riding, the issue of cadence vs torque sensor is largely irrelevant.

Many e-bike models are adding torque sensors now, such as the recently updated Aventon Soltera, since more riders are starting to demand the highly refined riding experience.

In conclusion

Choosing between torque and cadence sensors ultimately boils down to your personal riding style and preference. If you’re seeking an e-bike experience that closely mirrors traditional biking with a responsive, dynamic feel, torque sensors are your best bet. This is especially true if you want to ride with a partner or in a group. However, if you value consistent, straightforward assistance regardless of pedaling force, and you want to save some cash, cadence sensors might be more up your alley.

Remember, the best e-bike is the one that aligns with your riding habits and budget, ensuring each journey is both efficient and enjoyable. So, take a moment, assess your biking goals, and choose the system that resonates best with your vision of the perfect ride. Safe cycling!

Tesla Optimus robot takes a suspicious tumble in new demo

Tesla Optimus robot takes a suspicious tumble in new demo

A new video surfacing from a Tesla demonstration in Miami this weekend shows the Optimus humanoid robot taking a nasty fall. But it’s not the fall itself that is raising eyebrows, it’s the specific hand movements the robot made on its way down, which strongly suggest it was mimicking a remote operator frantically removing a VR headset.

Humanoid robots are all the hype right now. Billions in investments are pouring in, and Elon Musk claims it will be a trillion-dollar product for Tesla, justifying its insane valuation.

The idea has been that with the advent of AI, robots in human form could use the new generalized artificial intelligence to replace humans in an increasingly larger number of tasks.

However, there are still many serious concerns about the effort, both at the ethical and technological levels.

Technologically, most humanoid robot demonstrations have relied on remote control by human operators – pointing to a remaining gap between the software and hardware.

We discussed how the robots at the “We, Robot” event were heavily teleoperated, despite Tesla not explicitly disclosing that fact to the public.

That was more than a year ago, and despite claims that Tesla has made “AI demos” of Optimus since, it appears the company still relies on teleoperation to control them during demonstrations.

The Tesla Optimus Miami Incident

This weekend, Tesla held an event called ‘Autonomy Visualized’ at its store in Miami. The goal was to showcase Tesla’s “Autopilot technology and Optimus.”

However, there was nothing “autonomous” at Tesla’s “autonomy” event.

Many Tesla fans were seen posting videos of a Tesla Optimus robot handing out bottles of water at the event. It was also seen posing for pictures and dancing.

On Reddit, someone posted a different video of the demonstration:

As you can see, Tesla Optimus moved its hands too quickly, causing some water bottles to drop to the ground. It then loses its balance and begins to fall backward.

But the most interesting part is that just before falling backward, both of its hands immediately shoot up to its “face” in a distinct grasping motion, as if pulling an object off its head.

The robot, of course, is not wearing anything on its head.

The motion is instantly recognizable to anyone who has used VR or watched teleoperation setups. It appears the human operator, likely located backstage or in a remote facility, removed their headset in the middle of operating the robot for unknown reasons.

Optimus faithfully replicated the motion of removing a non-existent headset as it crashed to the floor.

Here’s a look at how Tesla trained Pptimus with VR headsets in its lab:

Electrek’s Take

This is embarrassing, but not just because the robot fell. Robots fall; that’s part of the R&D process. Boston Dynamics blooper reels are legendary, and they never really eroded the company’s credibility.

The problem here is the “Wizard of Oz” moment.

The specific motion of removing the “phantom headset” destroys the illusion of autonomy Tesla tries so hard to curate.

Even recently, Musk fought back against the notion that Tesla relies on teleoperation for its Optimus demonstration. He specified that a new demo of Optimus doing kung-fu was “AI, not tele-operated”:

Musk said again during Tesla’s last earnings call in October:

“Optimus was at the Tron premiere doing kung fu, just up in the open, with Jared Leto. Nobody was controlling it. It was just doing kung fu with Jared Leto at the Tron Premier. You can see the videos online. The funny thing is, a lot of people walked past it thinking it was just a person.”

Musk keeps telling shareholders that Optimus will be the biggest product in history and that millions of units will be working in factories soon. But if they are still relying on 1:1 teleoperation to hand out water bottles right now, it feels like we are still far away from a useful generalized Optimus robot.

The electric crossover that could help save Nissan: meet the all-new NX8

The electric crossover that could help save Nissan: meet the all-new NX8 

After images of an the new mid-sized electric crossover were leaked by the Chinese MIIT, Nissan pulled the wraps off its all-new NX8 – and it looks so good, I’m wondering if it couldn’t spearhead the brand’s American turnaround.

Nissan has had a rough go of it in the US, if not, well – everywhere of late. And while we may all have our own ideas about what Nissan needs to do to turn its ship around and get back to its winning ways, one thing just about every auto industry analyst seems to understand is that, at its core, Nissan’s problem is a product problem.

It doesn’t have to be this way, though. Despite what the optics of cynically slapping a Nissan badge on a decade-old Mitsubishi platform and calling it a new Rogue might have you believe, Nissan happens to have fantastic, modern new products in its production pipeline – including the all-new NX8 BEV and EREV crossover shown here. There’s just one problem: Nissan’s comeback cars are all in China.

Dongfeng Nissan, a Chinese-market automotive joint venture between Dongfeng Motor Group and Nissan, has been rolling out hit after hit in recent months, like the N6 (above), which sits between the Altima and Maxima, size-wise, and offers 112 miles on a full charge of its 21.1 kWh LFP battery before its 1.5L gas engine kicks on to keep the odometer rolling.

The N6’s stablemate, the all-electric Dongfeng Nissan N7 sedan, debuted a few months earlier to rave reviews and hot sales, too – moving more than 10,000 units in the model’s first three weeks on the market.

Like its sedan siblings, the all-electric version of Nissan NX8 crossover rolls on an 800V system architecture and features a CATL-sourced LFP battery pack with 5C ultra-fast charging technology (xC is how many you can charge in an hour, effectively, so 60 minutes divided by 5 = it can charge in as little as 12 minutes). That battery reportedly sends power to a single electric motor putting out either 215 kW (~290 hp) or 250 kW (~335 hp), depending on model.

EREV version of the NX8, meanwhile, features a similar setup to the N6, pairing a 1.5L ICE producing 109 kW (~145 hp) with a 195 kW (~260 hp) electric motor. Expect the NX8 EREV to get slightly less than the N6’s claimed 112 miles of electric-only range (Chinese cycle).

The NX8 is expected to reach its first customers in April 2026. Take a look at some of the firs official photos of the new Nissan crossover, below, then let us know how you think this would do in the US in the comments section at the bottom of the page.

Chinese quality: BYD launches 'Zero Defects' as it crosses 113 GWh in Q3

This week, BYD crossed a major manufacturing milestone as its battery production crossed 113 GWh in the first three quarters of 2025 – but instead of celebrating, the company is doubling down with a new “Zero Defects” initiative to bring battery quality to an even higher level.

CarNewsChina reports that the new “Zero Defects” plan at BYD was launched internally at the start of Q3, with a focus on minimizing manufacturing defects across all stages of the battery’s life, from the manufacturing line to the end user.

The initiative coincides with BYD’s growing role as a battery supplier to other automakers and its expanding battery energy storage system (BESS) business, which are giving BYD both an international footprint and global benchmarks.

In its ongoing bid to prove itself even further in the global battery market, BYD will reportedly emphasize operational efficiency, error reduction, and standardization across manufacturing, process control, and customer service, with the end goal believed to be, “management practices comparable to those of Toyota.”

The Chinese automaker seems to be going from strength to strength in 2025, having overtaken EV sales leader Tesla in China back in June and repeating the trick again by overtaking Tesla sales in Europe in August.

Combine those EV sales with the fact that its domestic traction battery production reached 113.42 GWh in just the first three quarters of the year (with 23.65 GWh, or ~20%, being supplied to outside customers – including Tesla), and you might agree that betting against BYD seems to be a bad idea.

Note that BYD has not released official details regarding performance metrics or milestones for its new Zero Defects goal, but the message is clear: BYD plans to keep getting better.
