When I first saw the JackRabbit MG Doble upon its unveiling earlier this year, I wasn’t totally sure what to expect. It’s not quite a full-size electric bike, but definitely not a mini-bike either. It has no pedals, yet it feels like a legit vehicle, not a toy. And while its higher price tag isn’t exactly budget-friendly, the Doble offers something that’s surprisingly rare in the e-bike world: a two-person ride that’s actually fun, compact, and borderline addictive.

To see what I mean about how fun this bike is to ride, check out my video review below. Or just keep reading to get the full picture!

JackRabbit has already made a name for itself with quirky, ultra-lightweight microbikes like the JackRabbit OG and XG series. Dubbed “micro e-bikes”, despite their lack of bicycle pedals, they tend to feel like small electric bicycles while maintaining the portability and lightweight convenience of an electric scooter.

But the MG Doble is a big step up – in power, size, and versatility. At first glance, it looks like someone stretched a JackRabbit XG and beefed up the frame. But once you hop on, it becomes clear: this thing feels more like a stripped-down motorcycle than a blown-up microbike.

It’s technically still smaller than a full-size e-bike (sporting a front 24×3″ tire mismatched with a rear 20×3″ in true mullet fashion), which makes it easy to stash in an apartment, car trunk, or even a hallway. But the ride position and handling make it feel stable and substantial. As someone who rides everything from 25 lb e-bikes to 500 lb electric motorcycles, I can tell you that it weirdly feels like it borrows from both worlds.

And whether riding solo or with a passenger on the long banana-style seat, it never felt twitchy or undersized to me. I wouldn’t call it “spacious,” but the ergonomics are surprisingly dialed for something that fits in places most e-bikes wouldn’t dare.

Fold it, stash it, ride it again

Speaking of that ability to fit just about anywhere, one of the best features on the Doble is the folding design. The handlebars spin around 90-degrees and the foot pegs fold in, which shrinks the Doble’s footprint considerably into something barely wider than a bare bicycle frame.

You’re not fitting it in a backpack or anything, but you can tuck it next to a wall or inside a hallway without taking up half the space of a regular bike. As someone who lives in an apartment with around 3x the number of bikes as people, anything that can live flat against the wall without handlebars sticking out is a game changer for space savings.

That feature makes it one of the more realistic two-person e-bikes for urban dwellers who don’t have a garage or shed to stash their rides. This is a bike that can offer the two-up riding advantages of a motorcycle, yet stashes against the wall in a space no wider than a rolled up yoga mat.

The vibes are one of the best parts

I’ve tested a lot of e-bikes. Like, hundreds of e-bikes. Some are fast. Some are practical. Some are comfortable. But few are as downright fun as the MG Doble. There’s something about the way it takes off, the way it leans into corners, the way your passenger holds on when you accelerate – it just delivers this goofy grin factor that’s hard to describe. It’s quick, nimble, and feels more like a personal scooter-meets-minibike hybrid than a traditional e-bike. But in the best possible way.

Yes, there are no pedals. That means no exercise and, for some, an immediate disqualifier. But it also means no weird pedal placement issues or crank arms hitting your passenger’s legs. This was built to be throttle-only, and JackRabbit leans into that unapologetically. You’re not pretending to pedal here – you’re just mashing the throttle and enjoying the ride.

And by doing away with the pretense of pedaling, JackRabbit doesn’t run into the same issues that many pretend e-bikes have, trying to sneak a nearly 100-lb mini motorcycle into bike lanes with a pair of theoretically usable but practically unused pedals getting in the way. Instead, JackRabbit delivers the Doble as a mere 52-lb two-seater that glides easily at 20 mph (32 km/h), or can hit higher speeds of 24 mph (38 km/h) in unlocked mode designed for off-road use.

Power and portability

The MG Doble is surprisingly powerful for its size. The “749 Watt” motor seems suspiciously rated in a way has me thinking it might not stop exactly at 749 watts. It definitely delivers plenty of torque for city riding, and the throttle response is snappy without being jerky. It climbs hills better than you’d expect (though I only had minor hills and parking garage ramps to test it on in pancake-flat Florida), and it doesn’t feel like it’s working hard to carry two people. In fact, I really didn’t notice a difference in power, even with a 110 lb passenger on the back.

The wide handlebars give it great stability and maneuverability, though there is a tradeoff: when you’re making tight turns, your hands have to reach all the way forward to the outside bar end with those wide grips, which can be a little awkward if you’re used to narrower bars.

That said, I’ll take the wide bars over twitchy steering. It feels planted in corners and stable at speed, which is especially important when riding two-up.

That being said: if you’ve never ridden with a passenger before, take some time getting to know the bike before bringing a friend or partner along. My wife and I live a car-free life and spend most of our commuting time on two-wheels, either separately or together on the same bike/scooter/motorcycle/whip-of-the-day. If you’re just getting started in your two-up riding career, start slow and practice in a parking lot or other open area so you can see how turns and sudden braking affect the ride. And remind your girl (or guy) to essentially be a backpack, not trying to balance things out themselves but to just hold on to you and let you do the work.

Rangebuster batteries are a game changer

One of my favorite features on the MG Doble is the battery system. JackRabbit’s “RangeBuster” swappable batteries are small, lightweight, and easy to carry – but they offer solid range for their size. Each battery is good for 24 miles (38 km) of range, meaning you’re packing 48 miles (77 km) of range with the pair of them on the Doble. I can’t imagine someone needing more range that that, but if you did, they’re easy to carry as spare batteries. Instead of lugging around a typically bulky e-bike battery, you can toss a spare RangeBuster or two in your backpack and swap it in seconds when you run low on charge.

It’s a brilliant solution for urban riders, delivery workers, or anyone who wants to go further without the bulk. However, it’s worth noting that the battery locks are sold separately. They come with the convenient thumb twist lock to hold the battery in, but if you’ll be locking your bike up, you might want to opt for the keylock accessory. For a $2,499 e-bike, I would have liked to see those included standard.

Are those hydraulic disc brakes?

JackRabbit touts the MG Doble’s hydraulic disc brakes, though if you look closer, you see mechanical cables running from the brake levers on the bars. So what gives?

Well, these are actually what are commonly referred to as hybrid hydraulic brakes. There’s a hydraulic piston doing the braking, but not where you’d expect. Instead of the piston being mounted with a reservoir up on the bars, it’s actually down on the caliper itself. A mechanical cable actuates it instead of sending hydraulic oil through lines down to the caliper.

You get the power advantages of hydraulic brakes as well as the at-home workability advantages of mechanical brakes. But like all good compromises, they’re also a compromise. You do end up with some cable stretch over time, though not as much or as frequently, since you don’t have to pull the cable as hard to get strong braking power.

So it’s an interesting solution, but not one we see very often in the e-bike world.

The price and the pedal-free problem

That brings us to the elephant in the room: the price. At $2,499, the MG Doble isn’t cheap. You can get a full-suspension fat tire e-bike with more power and more range for less. But it won’t be this compact, this fun, or this capable at carrying two people in such a small footprint.

To put it frankly, the JackRabbit MG Doble can do things that no other bike can do. It just can. You can debate whether or not that makes it worth the price (and there are legitimate arguments to be made either way). But you can’t say it’s not an innovative, interesting solution that required some pretty unique engineering to get there.

And sure, it’s got downsides. You’re sacrificing the ability to get any sort of workout. You don’t get any suspension. And you’ll probably end up with a few bugs in your teeth from all the smiles.

For me, the lack of exercise is ok. I have plenty of other rides with pedals and I rely on my morning run for that health fix, anyway. When I hop on a bike like this, it’s more about transportation, not a workout.

And I get that JackRabbit had to invest significantly in the development of such a unique bike that can’t rely on the same economies of scale leveraged by all the other countless e-bikes out there sharing the exact same components. But jeez, that’s still quite a stack of cash.

What’s my summary?

I will say unequivocally that the JackRabbit MG Doble is a blast. It’s compact, powerful, and fun – and it fills a very specific niche that few other e-bikes touch. It’s not trying to be everything to everyone. It’s trying to be a two-person, throttle-powered, fun-loving little beast. And in that regard, it nails it.

Yes, it’s expensive. And no, you’re not going to break a sweat riding it. But if you’re looking for a compact two-seater e-bike that’s portable, peppy, and bursting with personality, the MG Doble is one of the most enjoyable options I’ve tested all year.

Mercedes-Benz High-Power Charging and Starbucks have officially opened their first DC fast charging hub together, off the I-5 in Red Bluff, California.

The 400 kW Mercedes-Benz chargers are capable of adding up to 300 miles in 10 minutes, depending on the EV, and every stall has both NACS and CCS cables – they’re fully open DC fast chargers.

Mercedes-Benz HPC North America, a joint venture between subsidiaries of Mercedes-Benz Group and renewable energy producer MN8 Energy, first announced in July 2024 that it would install DC fast chargers at Starbucks stores along Interstate 5, the main 1,400-mile north-south interstate highway on the US West Coast from Canada to Mexico. Ultimately, Mercedes plans to install fast chargers at 100 Starbucks stores across the US.

Mercedes-Benz HPC opened its first North American charging site at Mercedes-Benz USA’s headquarters in Sandy Springs, Georgia, in November 2023 as part of an initial $1 billion charging network investment. As of the end of 2024, Mercedes had deployed over 150 operational fast chargers in the US, but it hasn’t disclosed an official number of how many chargers are currently online.

Tesla AI4 vs. NVIDIA Thor: the brutal reality of self-driving computers

Tesla AI4 vs. NVIDIA Thor: the brutal reality of self-driving computers


The race for autonomous driving has three fronts: software, hardware, and regulatory. For years, we’ve watched Tesla try to brute-force its way to “Full Self-Driving (FSD)” with its own custom hardware, while the rest of the automotive industry is increasingly lining up behind NVIDIA.

Now that we know Tesla’s new AI5 chip is delayed and won’t be in vehicles until 2027, it’s worth comparing the two most dominant “self-driving” chips today: Tesla’s latest Hardware 4 (AI4) and NVIDIA’s Drive Thor.

Here’s a table comparing the two chips with the best possible specs I could find. greentheonly’s teardown was particularly useful. If you find things you think are not accurate, please don’t hesitate to reach out:

Feature / Specification Tesla AI4 (Hardware 4.0) NVIDIA Drive Thor (AGX / Jetson)
Developer / Architect Tesla (in-house) NVIDIA
Manufacturing Process Samsung 7nm (7LPP class) TSMC 4N (custom 5nm class)
Release Status In production (shipping since 2023) In production since 2025
CPU Architecture ARM Cortex-A72 (legacy) ARM Neoverse V3AE (server-grade)
CPU Core Count 20 cores (5× clusters of 4 cores) 14 cores (Jetson T5000 configuration)
AI Performance (INT8) ~100–150 TOPS (dual-SoC system) 1,000 TOPS (per chip)
AI Performance (FP4) Not supported / not disclosed 2,000 TFLOPS (per chip)
Neural Processing Unit 3× custom NPU cores per SoC Blackwell Tensor Cores + Transformer Engine
Memory Type GDDR6 LPDDR5X
Memory Bus Width 256-bit 256-bit
Memory Bandwidth ~384 GB/s ~273 GB/s
Memory Capacity ~16 GB typical system Up to 128 GB (Jetson Thor)
Power Consumption Est. 80–100 W (system) 40 W – 130 W (configurable)
Camera Support 5 MP proprietary Tesla cameras Scalable, supports 8MP+ and GMSL3
Special Features Dual-SoC redundancy on one board Native Transformer Engine, NVLink-C2C

The most striking difference right off the bat is the manufacturing process. NVIDIA is throwing everything at Drive Thor, using TSMC’s cutting-edge 4N process (a custom 5nm-class node). This allows them to pack in the new Blackwell architecture, which is essentially the same tech powering the world’s most advanced AI data centers.

Tesla, on the other hand, pulled a move that might surprise spec-sheet warriors. Teardowns confirm that AI4 is built on Samsung’s 7nm process. This is mature, reliable, and much cheaper than TSMC’s bleeding-edge nodes.

When you look at the compute power, NVIDIA claims a staggering 2,000 TFLOPS for Thor. But there’s a catch. That number uses FP4 (4-bit floating point) precision, a new format designed specifically for the Transformer models used in generative AI.  

Tesla’s AI4 is estimated to hit around 100-150 TOPS (INT8) across its dual-SoC redundant system. On paper, it looks like a slaughter, but Tesla made a very specific engineering trade-off that tells us exactly what was bottling up their software: memory bandwidth.

Tesla switched from LPDDR4 in HW3 to GDDR6 in HW4, the same power-hungry memory you find in gaming graphics cards (GPUs). This gives AI4 a massive memory bandwidth of approximately 384 GB/s, compared to Thor’s 273 GB/s (on the single-chip Jetson config) using LPDDR5X.  

This suggests Tesla’s vision-only approach, which ingests massive amounts of raw video from high-res cameras, was starving for data.

Based on Elon Musk’s comments that Tesla’s AI5 chip will have 5x the memory bandwidth, it sounds like it might still be Tesla’s bottleneck.

Here is where Tesla’s cost-cutting really shows. AI4 is still running on ARM Cortex-A72 cores, an architecture that is nearly a decade old. They bumped the core count to 20, but it’s still old tech.  

NVIDIA Thor, meanwhile, uses the ARM Neoverse V3AE, a server-grade CPU explicitly designed for the modern software-defined vehicle. This allows Thor to run not just the autonomous driving stack, but the entire infotainment system, dashboard, and potentially even an in-car AI assistant, all on one chip.

Thor has found many takers, especially among Tesla EV competitors such as BYD, Zeekr, Lucid, Xiaomi, and many more.

Electrek’s Take

There’s one thing that is not in there: price. I would assume that Tesla wins on that front, and that’s a big part of the project. Tesla developed a chip that didn’t exist, and that it needed.

It was an impressive feat, but it doesn’t make Tesla an incredible leader in silicon for self-driving.

Tesla is maxing out AI4. It now uses both chips, making it less likely to achieve the redundancy levels you need to deliver level 4-5 autonomy.

Meanwhile, we don’t have a solution for HW3 yet and AI5 is apparently not coming to save the day until 2027.

By then, there will likely be millions of vehicles on the road with NVIDIA Thor processors.

Velotric’s Black Friday Sale switches gears with up to $750 increased savings and new lows starting from $999

Velotric has switched its Black Friday Sale into a higher gear with increased savings, new low prices, and expanded bundle packages on its e-bike lineup for a short-term window through Cyber Monday – plus, the option to save 30% on three accessories. One notable expanded package is the Velotric T1 ST Plus Lightweight Urban e-bike, coming with a FREE range extender battery ($400 value) for $1,299 shipped. You’d have to pay $1,649 for the e-bike on its own without any discounts, with that extra battery running that price up to $2,049. The brand’s early Black Friday deal only offered $350 savings (with the bundle being a rear cargo rack), but for this short-term change-up, you’re getting $750 in total savings that returns the tag to the lowest price we have tracked in 2025. Head below to check out the full lineup of Velotric’s expanded Black Friday Sale savings.

One of my favorite options from Velotric’s lineup, the T1 ST Plus e-bike, is a lightweight commuter that weighs only 39 pounds, and if you’ve read any of my e-bike reviews, you know I often lean towards models that can be easily handled up and down my rather large stoop. It brings a more European-style minimalist elegance to your travels, though keep in mind this model doesn’t possess a throttle, so it’s all PAS action. The 350W rear hub motor (with a 600W peak) is paired with a 352.8Wh battery for up to 70 miles of assisted travel at up to 20/28 MPH top speeds, depending on your local laws. What’s more, with the range extender battery, which connects right to this bike’s frame, boosts your pedal-assisted travel up to 100 miles in total, giving you serious commuting power.
