For anyone navigating the crowded world of electric bikes—whether you’re a daily commuter tired of traffic, a weekend adventurer chasing trails, or just someone who wants a fun, reliable ride—the MACFOX Upgrade X1S stands out as a versatile, well-built option that balances performance, style, and practicality. We spent weeks testing it on city streets, dirt paths, and even a snowy park (yes, the fat tires handle that too), and talked to real users to get the full picture of what makes this e-bike a winner.
Power That Delivers: Motor & Performance
At the heart of the X1S is an upgraded 500W brushless motor (with a peak power of 750W) paired with 50 Newton-meters of torque. For context, that’s enough to tackle steep urban hills without breaking a sweat—we tested it on a 15% grade near our office, and it climbed smoothly without lag. The torque also translates to snappy acceleration: from a stop, it hits 20MPH in under 6 seconds, which is perfect for merging into city traffic or passing slower riders on trails. The top speed of 24MPH is compliant with most local e-bike laws (check your area, but this is a common limit for Class 2 e-bikes) and feels just right—fast enough to make commutes efficient, but not so fast that it feels unstable.
Real users back this up. “Good power, light weight—within 20 minutes I was doing 2-minute wheelies,” said Luke Rivera, a verified buyer who uses the X1S for both commuting and recreation. “I was worried it wouldn’t handle wheelies, but it’s perfect.” That kind of feedback matters: if a rider who prioritizes performance loves the power, it’s a sign the motor isn’t just numbers on a spec sheet—it’s useful in real life.
Battery Life & Convenience: Go Far, Charge Easy
The X1S runs on a 48V/10.4Ah removable lithium-ion battery. On a single charge, we got about 38 miles of mixed riding (city streets + dirt trails) at medium power—right in line with the advertised 40-mile range. For commuters, that’s enough for a round-trip from Brooklyn to Manhattan (about 15 miles each way) with juice left over. And if you need more, the battery is expandable: add a second one, and you’re looking at 76 miles—ideal for longer weekend rides or multi-day trips.
The removable design is a game-changer. Instead of hauling the entire bike up stairs to charge, you can pop the battery out (it’s light—about 7 pounds) and plug it into any standard outlet. We charged it overnight (about 4 hours from empty to full) and never had issues with battery life fading after multiple cycles.
A parent who bought the X1S for their son summed up the battery’s appeal: “He likes that it’s really fast, and I like that the range means he can ride around the neighborhood without me worrying about it dying.” That peace of mind—knowing the battery is reliable—makes this e-bike a practical choice for families or anyone who hates range anxiety.
Style Meets Function: Retro Design, Rugged Build
Let’s talk about the look: the X1S has a retro motorcycle vibe that turns heads. The black frame with clean lines, the round headlight (not included, but the mounting points are there if you want to add one), and the 20” fat tires give it a classic, muscular feel—nothing like the “plastic toy” look some e-bikes have. The aluminum frame is lightweight (total bike weight: 65 pounds) but durable: we dropped it once on a dirt trail (our fault, not the bike’s), and there wasn’t a scratch.
The 20” x 4” fat tires are a star feature. They’re wider than standard e-bike tires, which means more traction on loose surfaces like dirt, sand, or snow. We took it to a local park after a light snow, and it glided over slush without slipping—something a regular tire would struggle with. On city streets, the tires absorb potholes and cracks, so even bumpy roads feel smooth.
Comfort is key, too. The seat is made of polyurethane (PU) foam, which is firm enough to support you on long rides but soft enough to prevent soreness. “I love the seat—did a 2-hour ride yesterday and didn’t have any back pain,” said another user. The front suspension fork adds to that comfort: it soaks up bumps from tree roots or curbs, so you don’t feel every jolt in your wrists or shoulders.
Safety First: Brakes & Control
The X1S comes with front and rear mechanical disc brakes, and they’re excellent. We tested them at full speed (24MPH) on a downhill path, and they stopped the bike in about 10 feet—no skidding, no drama. The brake levers are ergonomic, too: even with gloves on, they’re easy to squeeze. Luke Rivera, the wheelie enthusiast, noted that while he added hydraulic brakes for extra stopping power, the stock ones “kept me safe while I was learning.” For most riders—commuters, casual trail users—the stock brakes are more than enough.
The 7-speed twist-grip shifter is another plus. It’s intuitive (twist forward to go up gears, back to go down) and works seamlessly with the motor. We used it on a hilly trail, shifting from 1st to 5th as we climbed, and the transition was smooth—no grinding, no lag.
Easy Assembly & Top-Tier Service
One of the biggest complaints about e-bikes is assembly, but the X1S avoids that headache: it comes 85% pre-assembled. We took it out of the box, attached the front wheel, handlebars, and seat, and were riding in 45 minutes. The instructions are clear (with pictures!), and all the tools you need are included. A user named Ed Elgamal summed it up: “Speedy delivery, easy to put together—thanks guys.”
MACFOX also has warehouses in Los Angeles and Atlanta, so shipping is fast (we got ours in 2 days). And if you have questions? Their customer service team responds within 24 hours—we emailed about a loose bolt, and they sent a replacement part for free. That kind of support matters: when you buy an e-bike, you want to know the company stands behind it.
Who Is This E-Bike For?
The X1S is versatile—really versatile. It’s great for:
- Commuters: The range, speed, and easy assembly make it perfect for getting to work without sitting in traffic.
- Recreation Riders: The fat tires handle dirt, snow, and trails—ideal for weekend adventures.
- Families: The 280-pound weight capacity means it fits most adults, and the removable battery is kid-friendly (no need to lift a heavy bike to charge).
- Style Lovers: The retro design stands out from generic e-bikes—you’ll get compliments everywhere you go.
Minor Quirks (But Nothing Deal-Breaking)
No product is perfect, but the X1S’s “flaws” are minor. The stock brakes are good, but if you’re into extreme riding (like Luke’s wheelies), hydraulic brakes are a nice upgrade. The display is basic—just speed, battery level, and power mode—but it’s easy to read in sunlight, which is more important than fancy features. And while the seat is comfortable, some taller riders (over 6’2”) might want a longer seat post—something MACFOX sells as an accessory.
Final Thoughts: A Great E-Bike for Real People
After weeks of testing and talking to users, the MACFOX Upgrade X1S stands out as a well-built, practical e-bike that doesn’t cut corners. The motor is powerful, the battery is reliable, the design is stylish, and the service is top-notch. Real users love it: “My son won’t stop riding it,” “AMAZING BIKE!!!,” “Great e-bike—speedy delivery.” Those aren’t just quotes—they’re proof that this e-bike works for real people, not just reviewers.
If you’re looking for an e-bike that’s fun, reliable, and looks good, the X1S is worth a closer look. It’s not the cheapest option out there, but it’s worth every penny for the performance and peace of mind.

The motor’s efficiency also means less battery drain at high speeds, so you don’t have to sacrifice range for speed.

The battery also has a built-in LED indicator so you can check the charge level at a glance—no more guessing if it’s ready to go.
A parent who bought the X1S for their son summed up the battery’s appeal: “He likes that it’s really fast, and I like that the range means he can ride around the neighborhood without me worrying about it dying.” That peace of mind—knowing the battery is reliable—makes this e-bike a practical choice for families or anyone who hates range anxiety. We also tested the battery in cold weather (35°F) and found only a 5% drop in range, which is impressive for lithium-ion batteries (they usually lose more power in the cold).
Style Meets Function: Retro Design, Rugged Build
Let’s talk about the look: the X1S has a retro motorcycle vibe that turns heads. The black aluminum frame with clean lines, the curved top tube, and the 20” fat tires give it a classic, muscular feel—nothing like the “plastic toy” look some e-bikes have. The frame is lightweight (total bike weight: 65 pounds) but durable: we dropped it once on a dirt trail (our fault, not the bike’s), and there wasn’t a scratch. The matte black finish also resists fingerprints and scuffs, so it stays looking new even after months of use.
The 20” x 4” fat tires are a star feature. They’re wider than standard e-bike tires, which means more traction on loose surfaces like dirt, sand, or snow. We took it to a local park after a light snow, and it glided over slush without slipping—something a regular tire would struggle with. On city streets, the tires absorb potholes and cracks, so even bumpy roads feel smooth. The wheels are made of durable plastic (with metal spokes) that’s light but strong—we hit a curb hard, and the wheel didn’t bend.
Comfort is key, too. The seat is made of polyurethane (PU) foam, which is firm enough to support you on long rides but soft enough to prevent soreness. “I love the seat—did a 2-hour ride yesterday and didn’t have any back pain,” said another user. The seat is also adjustable: you can raise or lower it to fit your height (we tested it with riders from 5’4” to 6’1”, and everyone found a comfortable position). The front suspension fork adds to that comfort: it soaks up bumps from tree roots or curbs, so you don’t feel every jolt in your wrists or shoulders. We rode it on a dirt trail with lots of rocks, and the suspension kept the ride smooth—no hand numbness, no backache.
Safety First: Brakes & Control
The X1S comes with front and rear mechanical disc brakes, and they’re excellent. We tested them at full speed (24MPH) on a downhill path, and they stopped the bike in about 10 feet—no skidding, no drama. The brake levers are ergonomic, too: even with gloves on, they’re easy to squeeze. The brakes also have a motor cutoff feature—when you squeeze the levers, the motor stops immediately, which adds an extra layer of safety (no accidental acceleration while braking).
Luke Rivera, the wheelie enthusiast, noted that while he added hydraulic brakes for extra stopping power, the stock ones “kept me safe while I was learning.” For most riders—commuters, casual trail users—the stock brakes are more than enough. We also tested the brakes in the rain: they still worked perfectly, with no squealing or loss of power.
The 7-speed twist-grip shifter is another plus. It’s intuitive (twist forward to go up gears, back to go down) and works seamlessly with the motor. We used it on a hilly trail, shifting from 1st to 5th as we climbed, and the transition was smooth—no grinding, no lag. The shifter is also located on the right handlebar, so you can change gears without taking your hand off the brake (important for safety).
Easy Assembly & Top-Tier Service
One of the biggest complaints about e-bikes is assembly, but the X1S avoids that headache: it comes 85% pre-assembled. We took it out of the box, attached the front wheel, handlebars, and seat, and were riding in 45 minutes. The instructions are clear (with pictures!), and all the tools you need are included (a hex key set and a wrench). A user named Ed Elgamal summed it up: “Speedy delivery, easy to put together—thanks guys.” We also watched a first-time e-bike owner assemble it: she took about an hour, and the only question she had was how to adjust the seat (the instructions covered that).
MACFOX also has warehouses in Los Angeles and Atlanta, so shipping is fast (we got ours in 2 days). And if you have questions? Their customer service team responds within 24 hours—we emailed about a loose bolt, and they sent a replacement part for free. That kind of support matters: when you buy an e-bike, you want to know the company stands behind it. We also checked their warranty: 1 year on the frame, 6 months on the motor and battery—standard for e-bikes, but reassuring.
Real-World Testing: What We Loved Most
We tested the X1S in a variety of situations, and here are our favorite moments:
- Commuting: We rode it to work every day for a week. The fat tires handled potholes and curb cuts easily, the motor got us up hills without sweating, and the battery lasted the whole day. We even took it on a bike lane over a bridge—no wind issues (the frame is stable at high speeds).
- Trail Riding: We took it to a local mountain bike park. The fat tires gripped the dirt, the suspension smoothed out rocks, and the motor helped us climb steep sections. We passed a few regular mountain bikers, and they asked where we got it—“That thing looks fun!”
- Snow Riding: We took it to a park after a 2-inch snowfall. The fat tires floated over the snow, and the motor kept us moving. We even did a few donuts (don’t tell MACFOX) — it was a blast.
- Night Riding: We added a front light (not included, but the X1S has a mounting point) and rode it around the neighborhood at night. The frame’s matte black finish looks cool in the dark, and the lights were bright enough to see the road clearly.
Minor Quirks (But Nothing Deal-Breaking)
No product is perfect, but the X1S’s “flaws” are minor and easy to fix:
- Display: The digital display is basic—just speed, battery level, and power mode (Eco, Normal, Sport). It’s easy to read in sunlight, but if you want more data (like trip distance or calories burned), you’ll need to add a third-party display.
- Seat Post: Taller riders (over 6’
