Mars 3.0: The Folding Fat Tire E-Bike That’s Out Here Breaking Rules

TL;DR

• 750 W motor (1,400 W peak) + torque sensor = quick, smooth acceleration

• Up to 65 miles range, 28 mph stock speed, 30 mph+ when unlocked

• Full suspension + 20″ fat tires = confident comfort on road and trail

• Smart upgrades: NFC unlock, TFT display, app integration, turn signals

• Folds fast but weighs ~70 lb—portable in theory, workout in practice

The Ride That Feels Like a Plot Twist

You expect folding electric bikes to be about convenience, not adrenaline. Then the Heybike Mars 3.0 rolls in and messes with that assumption. This thing’s built for riders who want punchy acceleration, comfort over bumps, and all the tech toys—without giving up the ability to fold it down for storage or transit.

The vibe is equal parts urban street and weekend trail. Fold it, unfold it, and it’s ready to switch roles. That versatility is its hook, but the way it delivers performance is what keeps you hooked after the first ride.

Muscle Under the Frame

At the heart of the Mars 3.0 is a 750 W motor (topping out at 1,400 W when pushed), paired with a torque sensor that makes power delivery feel instant and intuitive. You’ll hit 20 mph in around six seconds and cruise comfortably at Class 3’s 28 mph—or unlock it to break the 30 mph mark.

A 624 Wh battery feeds that motor for up to 65 miles of range, so you can easily stretch a single charge across multiple days of commuting or a full adventure day. It’s not just about speed—it’s about sustaining it without battery anxiety.

Comfort Without Compromise

If you’ve ridden smaller folding bikes before, you know they can feel twitchy or rough. The Mars 3.0 fixes that with a full-suspension setup: hydraulic fork up front and Horst-link rear suspension in the back. The 20″ fat tires soak up even more of the chaos, whether you’re hitting potholes, gravel, or curb drops.

This combo keeps the ride planted and easy to control. Add in hydraulic disc brakes for dependable stopping power, and you’ve got a bike that feels as safe at speed as it does rolling slow through crowded streets.

Tech That’s Actually Useful

Many e-bikes throw in “features” you never touch. The Mars 3.0’s upgrades earn their keep: NFC card unlock (plus PIN backup) for quick, secure starts; a crisp color TFT display that’s readable in full sun; and app integration for tuning settings and unlocking speed.

Other thoughtful touches—integrated lights, turn signals, horn, fenders, and a beefy rear rack rated for heavy loads—round out a setup that works just as well for grocery runs as it does for weekend escapes.

The Folding Factor (and the Weight Reality)

The folding design is solid: reinforced hinges, easy-grab latches, and a fold time of about 10 seconds. The folded package fits easily in an SUV trunk or corner of an apartment.

Here’s the truth, though: at roughly 70 lb, it’s not the bike you want to haul up three flights of stairs on the daily. The fold is more about fitting into tight storage spaces or tossing in a vehicle than carrying like a briefcase.

Bottom Line

The Heybike Mars 3.0 is proof you don’t have to pick between power, comfort, tech, and folding convenience. It’s a capable fat tire e-bike that accelerates hard, smooths out rough terrain, and folds down when you need it to. The weight is the only real trade-off—but the ride quality more than makes up for it.

Your move: Would you take a heavier foldable if it meant this much speed, comfort, and tech in one ride?
