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.

More is more

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.
