Heybike has just announced the launch of its new X-Series, with the Mars 3.0 and Ranger S 3.0 Pro comprising the first two big new models. Or maybe not so “big”, as they’re actually kinda compact-sized, at least for full-suspension e-bikes. They’re both 20″ wheel folding e-bikes, and they pack in a lot of performance into comfortable rides. I’ve been testing both, and today we’re jumping in with both feet to check out how well the Mars 3.0 rides.
First of all, as usual, it’s fun to start with a video review. So check out my riding experience below, then keep reading for the nitty gritty details.

Heybike has been on a roll lately with its growing lineup of electric bikes, and the new Mars 3.0 looks like it might just be the brand’s most exciting release yet. While it hasn’t yet been available to the public, I got a chance to check it out ahead of time, and based on everything we’ve seen and experienced so far, this full-suspension fat tire folder is a serious upgrade over the previous Mars. In fact, it gives nearly every other 20″ folding e-bike a serious run for its money.
The Mars 3.0, part of Heybike’s new X Series, is all about power, speed, and rider experience. It brings a beefed-up motor system, smoother folding, and suspension that actually works, plus a host of smart tech features that elevate it above your average budget folder. Here’s everything you need to know about Heybike’s newest electric mini-beast.

Powerhouse performance: the Galaxy Perform eDrive
Let’s start with what matters most to a lot of riders: power. The Mars 3.0 is built around Heybike’s proprietary “Galaxy Perform eDrive” system, and it delivers serious muscle. With a 750W nominal motor (peaking at 1,400W) and an eyebrow-raising 95Nm of torque, this thing jumps off the line harder than almost anything in its class.
Heybike claims a 0–20 mph time of just 6 seconds, and from what we’ve seen, that figure just about checks out. It’s quick, it’s punchy, and it’s powerful. That’s thanks to a nicely tuned torque sensor, which gives you more immediate and natural-feeling pedal assist than the old-school cadence systems we still see on far too many folders.
For anyone looking for more thrill, the speed limiter that comes programmed out of the box to 20 mph can be bumped to 28 mph through the Heybike App or the display. And for those who really want to live dangerously (or ride on private property), the display lets you push just a bit past 30 mph when fully unlocked. That turns the Mars 3.0 into a sort of moped-lite, ideal for riders who want motorcycle vibes without the licensing hassle, though it may push into actual moped laws in some states.
Real suspension, real comfort
It’s hard to overstate how rare it is to see real full suspension on a folding e-bike that doesn’t cost several thousand dollars. But the Mars 3.0 doesn’t just slap a spring on the back and call it a day, it uses a legitimate Horst link suspension setup in the rear and a hydraulic fork up front.
The result? A bike that actually absorbs bumps and trail chatter, instead of pogoing around or bottoming out. That makes a huge difference whether you’re tackling dirt trails or just dealing with broken city pavement.
Combine that suspension with the wide fat tires, and you’ve got a genuinely cushy ride, even at higher speeds. It’s not a downhill mountain bike, but for commuting, cruising, and exploring, it’s leagues ahead of other folders in this category.
Smart features that don’t feel gimmicky
Heybike’s recent bikes have been leaning more into tech, and in the Mars 3.0, those features actually add value.
The NFC card startup is one of those little touches that will make the bike feel more premium to some, though I find it to be a hassle. Maybe that’s because I’m usually parking somewhere safe and not worrying about e-bike theft as much, but the hassle of swiping the card or entering the PIN code is just an added step at startup for me.
That said, I’m sure a lot of people will like it, and so here is how it works. Tap the included NFC card to start, just like unlocking a Tesla. Don’t have your card handy? You can also unlock the bike via a PIN code or the Heybike app, which also gives you control over various ride settings like throttle mode, assist levels, and max speed.
The bright, full-color TFT display is easy to read and gives you all the basics: speed, battery, distance, assist level, and more, with a layout that actually feels well designed instead of thrown together.
And speaking of throttle: riders can choose whether they want it to follow the pedal assist level or always run at full power. It’s adjustable in the app and gives you more control over how you want to ride, something more e-bikes should offer. And you can even adjust how extreme you want the throttle or pedal assist ramping to feel. Want gentle starts? Set it at level 1. Want to fly off the line? Choose level 5. It’s a nice little customization feature that lets riders tune their ride instead of being stuck with whatever the company programmed.
Stops as well as it goes
Going fast is fun, but stopping fast is important too. Heybike didn’t skimp here either. The Mars 3.0 gets an upgraded hydraulic disc brake system with thick 2.0 mm rotors. Not only do they provide more bite and better heat management, but they also feel more confidence-inspiring when braking from 30+ mph.
That extra thickness means it can handle more heat and longer braking, which is important when stopping heavy bikes or descending hills, or both.
Braking is smooth, controlled, and powerful, which is crucial for a bike that accelerates this quickly and invites you to push its limits.
Drivetrain and gear shifting
The Mars 3.0 uses a Shimano Altus 8-speed setup, which isn’t top-tier, and frankly is closer to the bottom of the Shimano tier structure, but is fine for a bike at this price point. Shifting is fine and predictable, and the integration with the motor assist system is solid, gear changes are reflected in the pedal response in a way that feels natural and intuitive thanks to the torque sensor.
It’s the kind of drivetrain setup you’d normally expect on a bike like this. It’s not going to change your world, but it gets the job done.
Utility meets design
This thing is both fun and practical. The rear rack is upgraded and sturdier than the previous generation Mars e-bike, and the bike has a high weight capacity (up to 440 lbs total payload for the bike). Whether you’re hauling groceries, gear, or even a kid seat, the Mars 3.0 looks like it can handle it.
The new folding system is fast and easy, with better pivot points and a more ergonomic latch. Heybike says it takes 10 seconds to fold, and that’s not an exaggeration. It actually feels smooth and simple, which isn’t always the case with fat tire folders. Of course, the bike is heavy as hell at 70 lb (32 kg), and so sometimes the tricky part isn’t merely folding it, but manipulating it while folding it. As long as you’re relatively strong, it should be fine. Small women or others with less upper body strength may still have trouble. I can’t really imagine my wife folding this e-bike. She’s a strong woman, but there’s no amount of fortitude that can make up for the back muscles it takes to lift a 70 lb e-bike, even folded in half.
Final thoughts
The Mars 3.0 isn’t more than just a modest upgrade over the previous version. I’d call this a whole new beast. With real power, actual suspension, and smart features that make it more refined and useful, this is a folding e-bike that doesn’t ride like a compromise.
It’s not trying to be ultra-lightweight or minimalist. It’s a chunky, techy, high-speed, full-featured ride that’s more about fun and performance than portability. But hey, it still folds, which checks the box on portability… mostly.
For an incredibly reasonable $1,299 (or promotional price of $1,199) , the Mars 3.0 could end up being one of the best bang-for-your-buck full-suspension e-bikes of the year. It’s perfect for anyone who wants a powerful, full-suspension ride that doesn’t take up a ton of garage space, and who doesn’t mind the occasional speed-induced grin.
If you’re in the market for a go-anywhere, do-anything, rip-through-the-city-and-still-fold-it-up kind of e-bike that sports full suspension, the Heybike Mars 3.0 is absolutely one to watch.

Guys, I think JackRabbit has a two-person e-bike coming, errr… electric scooter? I’m not really sure what you call this thing, but it looks wild.
I recently took a short break from riding and writing e-bikes all day to doomscroll social media, which basically just feeds me more bike content all day. And what popped up in my feed other than this peculiar thing?
Sure, it’s obscured by a surfboard mount, but there’s no getting around the fact that it looks like this shiny new silver JackRabbit isn’t quite as mini as we’re used to from the famously “micro and proud” micro e-bike maker. And there’s one other detail that’s also apparent if you look closely.
It’s a two-seater.
Advertisement – scroll for more content
I think this video was meant to be something of a teaser from JackRabbit, but it might as well be a near-unveiling.
In other parts of the same teaser video, almost the entire bike is visible. From those other shots, we can see that it’s still not quite an e-bike in the traditional “comes with pedals” sense.
Instead, JackRabbit’s somehow simultaneously chunky yet tiny folding footpegs are still visible. The wide handlebars also appear to have JackRabbit’s unique 90º turning handlebar lock, which allows the bars to spin sideways when parked. You can even see it in use in the images below.
On JackRabbit’s smaller models, that trick makes the entire bike just 7″ (17 cm) wide, making it easy to store behind a couch or under a dorm bed. Here, it’s unclear if it will be quite as narrow, but it should still make this a conveniently stowable ride.
It’s hard to tell, but it looks like the wheels might be larger than JackRabbit’s standard 20″ size, helping give it the “full-sized bike” qualifier that JackRabbit claims in the teaser video. The perspective is confusing, as the front wheel looks closer to 24″ or 26″, yet the rear wheel still disappears behind that surfboard. Could this be the first mullet JackRabbit? (Not to be confused with a JackRabbit mullet, which is a hairstyle that would pair well with what is likely the most free-spirited of all the e-bike brands out there.)
There may also be different saddle options, since we can clearly see what looks to be a conventional bicycle saddle in some images and a longer, stretched-out, banana seat-style saddle in the other shots.
We can also see two of JackRabbit’s “Rangebuster” batteries in the frame, a larger capacity pack developed by the company with a claimed 24 miles (39 km) range per battery, meaning this model might have a range of nearly 50 miles (80 km).
But there’s a lot we still don’t know. Will it get the powerfully torquey motor from the JackRabbit XG Pro? Will there be a pedal option? Will my wife agree to ride this thing with me? These are yet questions without answers, people.
One thing is for sure, though. JackRabbit says all will be revealed soon. “Everything you know about JackRabbit is changing on 8/12,” writes the company. (That’s next week, for any Europeans in the room.)
I don’t know about you, but I’m suddenly very much looking forward to Tuesday.
Electrek’s Take
I don’t know what to make of this, but I’m excited. I’ve been a JackRabbit fan since before the OG was even the OG. It’s just such a fun and free-spirited brand.
If the e-bike market was high school, JackRabbit would be that quirky, non-conformist kid that everyone kind of wondered about but who was obviously having more fun than anyone else. It’s the e-bike that just puts its hands over its ears and goes “La la la la…” when you try to tell ’em that it’s not actually an e-bike.
It’s weird. It’s wild. But it works. And being a JackRabbit fan is a hill I’m prepared to die on – though admittedly, you’d be well advised to tackle that hill on one of the Pro models instead of the OG2 for the extra power and torque.
My wife might give me a funny look every time I whip out my JackRabbit, but I still love riding it. And so it’s with that level of excitement and curiosity that I wonder what the brand that refuses to be defined is up to with this new “full-sized bike” reveal they’ve got coming. The ability to carry two riders sounds great, especially since the thing still looks so small and portable.
Of course, the over-priced elephant in the room is that JackRabbit’s Achilles heel is its pricing. These things aren’t cheap. The entry-level OG2 model only starts at $1,249, and the flagship XG Pro is almost double that. Granted, it’s an awesome bike, and one that I was able to use to tow a kayak down the road for miles, then put on top of that kayak and paddle through the Gulf of Mexico for miles (something of which I don’t know of any other e-bike that can do). But that makes me wonder what yet a bigger and presumably more impressive JackRabbit will cost.
But hey, I’m so here for this!

Small package, big impact: that’s the story behind Maxon’s new Air S mid‑drive motor. On the surface, it looks almost identical to the original Air: sleek, nearly invisible, and designed to disappear into your bike’s frame. But beneath this minimalist exterior is a dramatic leap in capability.
Now the torque has nearly tripled, soaring to 90 Nm, all while keeping total system weight to just 3.8 kg, (8.4 lb) including the motor and 400 Wh battery.
Just 100 g (0.22 lb) heavier than the original Air yet tripling the performance, the Air S delivers up to 90 Nm of torque and 620 W of peak power, catapulting it into the realm of powerful mid‑drive motors built for demanding trail performance. That’s the same torque you’d expect from some of the strongest mid‑drive motors in modern electric mountain biking, yet in a package that’s still feather‑light.

Why it matters for lightweight e-bikes
As New Atlas recently pointed out, these motors are enabling super lightweight builds that previously weren’t possible: Bikes using the Air S, like the Thömus Lightrider E‑Max or Instinctiv’s Ocelot, tip the scales at barely 15 kg (33 lb), far lighter than typical full-suspension e‑MTBs, thanks largely to the slender motor and integrated battery design.
With torque now hitting 90 Nm, up from just that meager 30 Nm on the original, the Air S now delivers serious climbing power without the bulk. This brings light-assist bikes into full‑power territory, making acceleration and steep terrain feel effortless. Previously, ultra-lightweight e-bikes made serious compromises on power to achieve that level of near weightlessness. But now, they can actually compete on power, too.
Maxon’s unique split‑cylinder configuration also allows the motor to remain visually discreet. Combined with frame‑integrated batteries (400 Wh to start, with a 600 Wh option reportedly on the way), the system preserves clean lines and low weight. Many e-bikes sporting the motor simply won’t even look like e-bikes to the casual observer.
With the Air S, Maxon has struck a rare balance: ultralight design without compromise on torque. It catapults lightweight e-bikes into a new performance bracket, granting riders both agility and power. If you’ve long dreamed of an e-bike that feels like a mountain goat on the climb yet disappears under 16 kg, the Air S is probably your motor.
The trail-ready future is lighter, leaner, and looks ready to race uphill.

There you are, motoring along in your Volvo XC90 PHEV with the Pilot Assist engaged alongside a big 18-wheeler at a comfortable 70 mph cruise when the interstate starts to slowly sweep left. From the drivers’ seat, that semi on your right looks awfully close. As the steering wheel turns itself in your hand, you start to wonder if that truck’s a bit too close. The car isn’t doing anything wrong, but it’s too close for your comfort and you give the wheel a little nudge to hug the inside of the lane just a bit more.
These deeply personal preferences are tough to quantify, and highlight a simple fact about Advanced Driver Assistance Systems (ADAS) that the industry at-large hasn’t yet to come to terms with: when it comes to self-driving cars, one size does not fit all.
The Volvo experience I outlined above was very real, happening just as the wife and I were arguing about the relative merits of our very different choice in running shoes. She prefers the supportive, cushion-y ride of the HOKA Clifton 9s, which I’ve become convinced are The Devil™, preferring instead the zero-lift, no-cushion feel of my Xero Prio runners. The intervention with the Volvo interrupted that particular argument and started another. Namely, the one about why I had chosen that moment to “interfere” with the Pilot Assist.
“It was too close to that truck,” I explained. “Freaked me out.”

“That’s how I feel in the Honda,” she said. “I’m always afraid that it’s going to try and put me into oncoming traffic.”
That’s when the idea for this post came to me. Because, as a car brand, it’s really not possible to just say that your car has ADAS or doesn’t have ADAS in a binary sense. That’s because these systems are not just proprietary to a given brand, they can vary from vehicle-to-vehicle within that brand, and each one can have distinct lane centering behavior, steering feel, lane change aggressiveness, braking distances, timing for its hand-off warnings, and probably a bunch of other stuff that I haven’t even thought of depending on what kind of cameras, sensors, and software the specific vehicle you are in is equipped with.
It’s a bit of a mess, in other words.
Opinion: Honda Sensing gets it right
I first experienced Honda’s ADAS in 2014, driving a then-new CR-V between Chicago and Bay Harbor, Michigan for an Acura press drive. Even in its early generations, I was impressed with the way it handled stop-and-go traffic, the way it guided you through turns, but didn’t do the turning for you, and the speed and intensity it used in braking very much mirrored my own.
Last month, I had a chance to test out the 2025 Honda Civic Sport Touring Hybrid for a week on Cape Cod. I picked the car up at PreFlight Parking outside Boston Logan, jammed it with luggage, and immediately hit heavy traffic, where the Honda Sensing Low-Speed Follow function took me right back to 2014, ratatouille-style, when my experience in that car had led me to believe that self-driving cars were right around the corner.
In the decade-plus since experiencing that first autonomous Acura, I’ve had the chance to experience Ford BlueCruise, Tesla Autopilot and FSD, and Mercedes-Benz DRIVE PILOT. And all, interestingly enough, in and around the Circuit of the Americas in Austin at one time or another over my three years of hosting Electrify Expo events there.
Each different OEMs’ system had its strengths and quirks. I remember Mercedes DRIVE PILOT as impressively precise, even clinical. The Ford system faded into memory. I couldn’t tell you anything about it, which is probably high praise. The Tesla systems, though, stood out — but for all the wrong reasons. Lane changes came too quickly, it accelerated too late, and too aggressively, and I often found myself bracing for collisions that (in fairness) never came.
More than once in those years I’ve wondered if maybe I’d just got it wrong back in 2014. That the tech was so new, and I had been so wow’ed by it initially, that I had got swept up in the hype of self-driving cars … but that drive in my wife’s XC90, back-to-back as it was with the Civic Hybrid, showed me that wasn’t it. Instead, I just didn’t like the way those other cars drove. Just like I don’t like the way HOKAs feel. And, just like my wife isn’t wrong for liking her gross marshmallow shoes (probably), I’m not wrong for preferring a more restrained digital co-pilot.
It’s a matter of fit, not fact — and that’s going to be a tough sell.
Everyone but me is wrong
Classic Carlin bit.
As the great George Carlin once asked, “Have you ever noticed that anyone who is driving slower than you is an idiot, and anyone driving faster than you is a maniac?”
ADAS systems live squarely in that same subjective space occupied by other drivers. If the bots brake too hard, steer too sharply, or get too close to the car head before changing lanes, they might not be technically doing anything wrong, but they’re maniacs – and right now, there’s no real way to know how one car’s ADAS is going to behave until you’ve spent some significant time behind the wheel. Like, “Uh-oh. I bought a thing and I hate it,” amounts of time.
That’s a problem for both buyers and sellers (to say nothing of manufacturers and software developers), because why would you risk demonstrating a system that might scare someone? How do you sell “confidence” and “convenience” when what feels confident and convenient to one driver feels reckless to another, and milquetoast to a third?
Lucky for you guys, I have a solution.

That asterisk (*) is there because these are completely made up, imaginary values. They’re simply there to illustrate one way for manufacturers and dealers to share objective, quantifiable information about how their different ADAS systems behave. If it’s done right, it might help a car shopper get a better feel for how their next car might drive, and prevent them from spending their hard-earned cash on a car that drives like an idiot. Or a maniac.
That’s my take, anyway – what’s yours? Head down to the comments and let us know what values you’d like to see represented on an ADAS scorecard, and how much you’d be willing to base your next car buying decision on how it drives.
As for me, my X handle might be VolvoJo, but if I’m shopping for a car that’s going to drive me instead of the other way around, I might have to see if “HondaJo” is available.
