Commuter electric bikes are a key segment helping reduce America’s dependence on cars for navigating cities. The Propella 9S Pro V2 is designed squarely to get people to work, school, the coffee shop, or just navigating town on their own schedule. But compared to many other electric commuter bikes on the market, Propella does it with some outstanding value and several features we rarely see at this price level.
Want to watch the Propella 9S Pro V2 in action? Check out my video review below. Then keep reading for all of the juicy details!

A lot of e-bikes make it fairly obvious what features you’re getting. But there’s one important feature that you usually can’t see: torque sensors.
The Propella 9S Pro V2 includes a torque sensor, which is a major upgrade over the cadence sensors that most budget-level electric bikes use to activate their pedal assist.
We’ve talked about this before, but the summary is that torque sensors basically make the bike more comfortable and responsive since they better mimic real-world pedaling. Instead of the bike feeling laggy and then lurching forward, like with many cadence sensor e-bikes, an electric bike with a torque sensor will usually feel much more natural to pedal with responsive motor power.
But of course there’s more than just a torque sensor that makes the Propella 9S Pro so nice – even if that one single component is a great value-added piece of kit that we rarely see at this price.
Other nice components include the color LCD display, adjustable handlebars, hydraulic disc brakes, the 9-speed transmission, the built-in LED headlight, and the included fender set.
One note about that transmission: it’s great to have gear options, but ironically I found that I just left it in the highest gear all the time. I live in a flat city though, and so the advantages of constantly higher gearing make sense. If you have hills in your city, you’ll enjoy the gear options and not just treat it like a single-speed as I did.
Some folks will surely bemoan the lack of suspension, and I get it. A lot of people feel they need suspension for the added comfort. But if you can give it up, you’ll get a stronger and longer-lasting bike with fewer places for failure. In this case, the 2″ tires offer more cushion than most city bikes, and the fork even uses a 12mm thru-axle for the strongest connection compared to most cheap city e-bikes with quick-release skewers.
One downside of the bike though is that its 36V battery simply isn’t very big, measuring just 350 Wh. Though on the other hand, the lack of a throttle means that the bike will work more efficiently thanks to the pedal assist operation (they claim up to 50 miles or 80 km of range per charge). Despite the smaller size battery, at least it is removable with the included key, meaning you can charge it off of the bike when convenient. And it even comes with a fairly fast charger, filling the battery from empty in just 3 hours. In most cases though, the charge time will be even quicker since you’ll rarely ride the bike all the way to empty. That battery and bike are also SGS-certified to UL 2271 and UL2849 standards, which is becoming an important differentiator as concerns of battery safety propogate.
What’s the takeaway?
As an urban-oriented Class 1 e-bike that can hit 20 mph (32 km/h) quickly and easily thanks to that 500W peak rated motor, the Propella 9S Pro V2 is an ideal commuter e-bike. And at just 43.5 lb (19.7 kg), it’s pretty darn lightweight too – at least as far e-bikes go.
The company has added more and more features to their bikes over the years, giving us the 9S Pro V2 with just about everything that most commuters want – except for the throttle. Though if you’re really hung up about having a throttle, they did just release another Propella model that will quench your throttle thirst.
So all told, at US $1,299, the Propella 9S Pro is a steal. If you want a commuter e-bike with a great selection of parts for the price, you just can’t go wrong here. Well, not unless you want a colorway other than blue-on-black.

Tesla has reportedly yet to start testing its robotaxi service in Austin without a safety driver behind the wheel – just weeks before the planned launch.
For months now, Tesla and CEO Elon Musk have been hyping the launch of “Tesla Robotaxi”, a Uber-like ride-hailing service powered by autonomous Tesla vehicles, starting with a launch in Austin, Texas in June.
Instead, Tesla plans to build an internal fleet of “10-20” Model Ys and have them offer ride-hailing services in a geo-fenced area around Austin, Texas, helped by human teleoperations. This is very similar to what Waymo has been offering in other cities for years, specifically in Austin, for months now.

Even with the significant downgrade in self-driving capabilities promised with this project, there are many doubts about Tesla’s ability to achieve the lesser goal.
That’s because the robotaxi service will be based on Tesla’s ‘Supervised Full Self-Driving’ program, which is currently achieving about 500 miles between critical disengagements fleet-wide, according to the latest crowdsourced data.
Tesla will be able to improve on that by optimizing a version for the geo-fenced area in Austin and it has been training its neural nets for that for months with vehicles going around Austin.
However, a new report now claims that Tesla has yet to start testing its service without safety drivers at the wheel – similar to Tesla’s public ‘Supervised FSD’. The Information wrote in a new report:
Elon Musk’s deadline for launching Tesla’s first robotaxi service, in Austin, Texas, is weeks away, but the company hadn’t started testing its cars without a human safety driver as of last month, according to an engineer close to the testing and a former employee. That’s a crucial step required before Tesla can launch the pilot service for customers.
For comparison, before launching its paid ride service in Austin, Waymo tested its vehicles with safety drivers in the area for 6 months and then without safety drivers for another 6 months.
Waymo has now taken over a significant market share of ride-hailing rides in the Texas capital, but it still has limitations; for example, it doesn’t drive on the interstate.
The report also mentions that Tesla has been working with local emergency services in Austin to develop intervention plans in order to avoid causing issues if its autonomous vehicles fail.
Electrek’s Take
This is the biggest softball goal. It’s a fraction of what was promised, it’s something that others have achieved before. It’s a punt created for Tesla to finally get a “win” in self-driving.
If they can’t even make it, it would be disastrous, but at least, I hope that it will finally open the eyes of many Tesla shareholders to the reality that Tesla is actually behind in autonomous driving and that Musk’s latest claims that Tesla will have “millions of robotaxi on the road” in 2026 are just the same as when he claimed it would happen in 2025, 2024, 2023, 2022, 2021, 2020, and 2019: corporate puffery.
My main concern now is for public safety. I have little hope of US regulators being able to stop Tesla considering Trump is firing anyone who got in Musk’s way after he gave him over $250 million.
If Tesla brings its cowboy approach to this, it could get bad quickly.

The development of Rivian’s R2 validation builds continues to progress. We know so because the American automaker’s founder and CEO, RJ Scaringe, continues to pepper us with welcome updates with plenty of fantastic images. The latest post features the inner workings of Rivian’s Maximus drive unit, which will propel the upcoming R2 EVs when they hit the market next year.
Another day, another exciting social media update from RJ Scaringe. Nine days ago, the Rivian CEO shared a peek at the company’s new Maximus drive unit, designed to be more compact and efficiently built to help reduce cost-per-unit production.
Our only look was from outside the drive unit’s casing at the time, but it was exciting news nonetheless. As an encore, Scaringe posted photos of the R2 validation builds on a pilot line at the automaker’s facility in Normal, Illinois.
This evening, Scaringe took to Instagram and X once again to share a better look at the inner workings of the Rivian Maximus drive unit. Check it out:

RJ shares more images of Rivian’s Maximus development
Rivian’s CEO posted the three images above, which showcase some interesting perspectives of the developing drive unit. As previously shared by Rivian, Maximus uses a new continuous winding technique that reduces the total welds per stator and thus the total overall cost of building each one.
For comparison, Rivian’s current Enduro drive unit requires 264 stator welds, while Maximus only needs 24. You can see the stator windings in the image above to the left. Scaringe shared excitement in the progress of the Rivian team’s Maximus drive unit as well as some insight in his post:
I love the packaging on Maximus — the drive unit for R2. It has a side mounted inverter that utilizes flat area at the end of the motor to minimize the length of bus bars, keeping them light and efficient. The large planar shape also allows all processing and power electronics to exist on a single printed circuit board.
The inverter chassis closes out the oil cooled motor cavity and seamlessly routes coolant from the power modules to the drive unit’s heat exchanger with no extra parts.
Overall, the inverter part count is reduced by 41% relative to Enduro and structural inverter lid saves more parts and fasteners by also serving as the drive unit mount. I love this design efficiency. (heart emoji)
Looks fantastic, RJ. We can’t wait to see the visual progress of the R2 you share next!
