The Freesky Swift Horse Pro is not a subtle e-bike. On paper it reads like a wish list from riders who want maximum power and range in one package: a peak 2500W Bafang hub motor, a huge 48V 30Ah Samsung battery, full suspension, 4-piston hydraulic brakes, and 26"×4.0" fat tires. Add UL 2849 and UL 2271 safety certifications and a smart color display with NFC key card, and you start to see why this bike has become one of Freesky’s headline models.

In this in-depth review we’ll break down who the Swift Horse Pro is really for, what it does well, and where you need to manage expectations. If you’re considering a powerful fat-tire e-MTB for steep hills, loose terrain, and long weekend rides, this bike should definitely be on your shortlist.

Quick Verdict

The Freesky Swift Horse Pro is a brutally strong, long-range fat-tire e-mountain bike aimed at riders who prioritize power and range over low weight and minimalism. The 2500W peak Bafang motor and 48V 30Ah Samsung battery deliver serious hill-climbing punch and all-day endurance, while full suspension and 4-piston hydraulic brakes keep things controllable on rough ground.

It is not a light, nimble city commuter or a legal Class 1/2 bike in many regions once you unlock the full 38+ mph PAS speed. It’s heavy, overbuilt, and unapologetically biased toward performance. If that’s what you’re after, you’ll probably love it.

What Is the Freesky Swift Horse Pro?

The Swift Horse Pro is Freesky’s flagship fat-tire mountain e-bike. It sits in the “high-power trail and all-terrain” segment rather than the typical urban commuter category. Think of it as a full-suspension, motorcycle-inspired e-MTB that happens to have pedals—built for dirt, snow, forest tracks, and hilly backroads where extra torque and battery capacity really matter.

Freesky as a brand focuses heavily on value-packed, feature-rich e-mountain bikes, and the Swift Horse Pro is a showcase of that philosophy. Instead of using a modest 750W motor and 15Ah battery, they went all-in with a peak 2500W Bafang hub motor and a 30Ah Samsung pack. That choice immediately tells you who they’re targeting: riders who want power, speed, and range that exceed what typical big-box e-bikes provide.

The design goal here is clear: build a bike that can haul a heavier rider up steep grades, carry gear on the rear rack, soak up rough terrain with full suspension, and still have enough juice left to get back home without stressing the battery. It’s a long-range adventure machine first, a daily commuter second.

Who Is the Freesky Swift Horse Pro Best For?

Ideal for

• Riders in very hilly areas. If you live somewhere with long, steep grades or rough fire roads, the combination of 140 Nm torque and fat tires makes climbing feel almost effortless—especially if you’re a heavier rider or often carry cargo.
• Bigger or fully loaded riders. The 400 lb payload rating and stiff frame mean this bike is comfortable hauling a large rider, plus gear in the rear bag or panniers.
• Adventure and trail use. Sand, snow, loose gravel and rutted forest paths are where the Swift Horse Pro feels most at home. The fat tires and full suspension smooth out ugly surfaces that would rattle you to pieces on a rigid commuter.
• Range-anxiety haters. If you regularly knock out 30–50 mile rides or want to explore all day without worrying about finding an outlet, the 30Ah battery is a huge confidence boost.
• Tech-curious riders. The NFC key card, password lock, and colorful display with USB-C charging give the bike a modern, gadget-friendly feel.

Not ideal for

• Riders who must strictly follow Class 1 / 2 limits. Even though you can limit the speed, the bike’s capabilities (and weight) clearly go beyond typical Class-legal commuters. Some regions may classify it as a moped when de-restricted, so you’ll want to check local regulations.
• Apartment dwellers without an elevator. At close to 90 lb, this is not a bike you casually carry up a few flights of stairs.
• Riders under roughly 5'3". With a minimum seat height around 34" and a fairly tall standover, shorter riders may find it intimidating to mount and dismount.
• People who prefer light, nimble bikes. If you’re coming from a 35–40 lb fitness bike, the Swift Horse Pro will feel like a small electric motorcycle.

Budget & value

In terms of positioning, the Swift Horse Pro sits in the mid-to-upper range of consumer e-MTBs. For around the $1,800–$2,000 mark (prices move with promotions), you get significantly more battery and motor than many mainstream 750W/15Ah competitors, plus full suspension and 4-piston brakes.

The trade-offs for this value are weight, some budget-level finishing components, and a performance envelope that may exceed local e-bike rules. If you’re okay with that, the specs-for-dollars ratio is impressive.

Design, Frame & Build Quality

Visually, the Swift Horse Pro looks like a purpose-built trail machine. The large downtube houses the 48V 30Ah battery, giving the frame a chunky profile that actually suits the fat-tire stance. Welds are fairly clean for this price bracket, and the matte paint with red or accent graphics gives it a modern, slightly aggressive look rather than something that screams “cheap online bike.”

The 6061 aluminum frame uses a classic front triangle paired with a rear swingarm and air shock. The geometry leans more toward stable than super-nimble: a relatively long wheelbase and wide bars give you a planted feel at speed, which is exactly what you want when the bike can do 30+ mph on dirt. The integrated rear rack shares the same color scheme and feels like part of the bike, not an afterthought.

Cable routing is semi-internal. The main loom ducks into the frame near the headtube and exits near the components, which keeps snags to a minimum. There’s still some visible wiring around the bars and rear rack—this isn’t a $5,000 fully integrated e-MTB—but nothing looks sloppy.

Fenders and rack are metal rather than flimsy plastic, which helps with durability, though you may pick up some rattle on rough terrain if bolts work loose over time. Overall, the impression is of a heavy-duty workhorse that’s meant to be ridden hard, not babied.

Motor Performance & Speed

The headline feature of the Swift Horse Pro is that 2500W peak Bafang rear hub motor. In practice, “2500W peak” means it’s running a powerful 48V system with a controller that can draw enough current to deliver very strong bursts of torque. With up to 140 Nm on tap, the bike surges forward eagerly even from a low roll.

Acceleration & everyday speed

On flat ground, pedal assist in the middle levels already feels strong. PAS 1–2 give you a relaxed, cruiser-style ride suitable for bike paths and neighborhood streets. Once you bump into PAS 3–5, the bike becomes genuinely quick; it doesn’t take long to hit the low-20s mph range.

Unlock the top speed (by holding the right keypad button until “99” appears, according to Freesky’s instructions) and the PAS will willingly push toward the advertised 38+ mph, provided you’re pedaling and have enough open road. That’s motor-bike territory, and it can be a lot of fun on private property or suitable rural roads, but you must respect the power and understand any legal implications.

Throttle-only mode is more civil: it tops out around 20 mph. This is handy for getting going from a stoplight, tackling short hills, or taking a break from pedaling without turning the bike into a rocket every time you touch the lever.

Hill-climb ability

Steep hills are where this bike earns its “Swift Horse” name. On sustained grades around 10–15%, the motor climbs with authority as long as you keep cadence up and let the torque work. Even heavier riders will find that PAS 3–4 offers enough oomph to maintain mid-teens speeds on climbs where a 500–750W bike would start to bog down.

Short, punchy hills can often be dispatched with throttle only, though on very long climbs it’s better to use PAS and contribute some pedaling so you don’t overheat the motor or controller. Some independent testers have noted that running full power continuously for many miles can push the system toward thermal limits, reducing power temporarily—so treat the highest settings like a “boost” mode rather than an always-on default.

High-speed stability

Because the frame is long and the tires are big, the Swift Horse Pro remains surprisingly composed at 25–30 mph. The dual-crown fork stiffens the front end, and the wide handlebar provides plenty of leverage. You do, however, feel the mass of the wheels and frame when changing direction quickly; it prefers sweeping arcs over tight, flicky maneuvers. That’s a fair trade-off for the intended use.

Battery, Range & Charging

The 48V 30Ah Samsung battery is one of the defining features of this bike. At 1440 Wh, it’s roughly double the capacity of what you’ll find on many mid-priced e-bikes with 48V 15Ah packs. It’s also UL 2271 certified and managed by a built-in BMS for added safety, while the entire e-bike system carries UL 2849 certification.

Claimed vs real-world range

Freesky advertises up to 75–120 miles on a charge in pedal-assist mode, tested with a 75 kg (165 lb) rider, moderate PAS levels, and gentle conditions. That upper figure assumes very efficient riding: low PAS, relatively flat terrain, and conservative speeds.

In more typical mixed use—say, a 180–200 lb rider using PAS 3 on rolling terrain, cruising in the low-20s mph range—you should realistically expect something more in the 40–80 mile window. Ride mostly on throttle or stay in the highest PAS levels and the range will drop further, but you’ll still get a day’s worth of fun for most riders.

Battery design & practicality

The pack is semi-integrated into the downtube and locks in place with a key. You can charge it on or off the bike using the included 3A charger. From low to full, you’re typically looking at 8–10 hours, which is reasonable given the sheer capacity. An overnight charge is the easiest routine.

Weight-wise, the battery is hefty, but that’s the nature of a 30Ah pack. If you regularly carry the bike upstairs, you may want to remove the battery first to shave off some pounds.

Overall, the range and safety credentials make this a strong choice for riders who value long rides and battery longevity over minimal weight.

Ride Comfort & Handling

Comfort

Between the full suspension and 4" tires, the Swift Horse Pro leans toward the plush side of the comfort spectrum. The dual-crown front fork and air rear shock soak up potholes, roots, and washboard bumps better than entry-level spring setups found on cheaper bikes. Freesky claims that the combo reduces felt bumps significantly, and in practice you can roll over terrain that would be exhausting on a rigid frame.

The riding position is moderately upright. You’re not fully bolt-upright like on a Dutch city bike, but you’re far from hunched over an XC racer. That makes long rides easier on the neck and lower back. The stock saddle is wider and more padded than a sports saddle; combined with the suspension, it strikes a good balance between comfort and support.

The 26×4.0 CST fat tires add a final layer of cushioning. Run them around 15–20 psi for mixed terrain or drop a bit lower for sand and snow. At lower pressures the tires deform nicely over rocks and ruts, trading a bit of efficiency for extra grip and softness.

Over very long rides (30–40 km and up), most riders will appreciate the relaxed cockpit and suspension. If you’re extremely sensitive to saddle comfort, you might still want to add a suspension seatpost or a favorite aftermarket saddle, but out of the box it’s better than many budget competitors.

Handling & stability

At low speeds, the bike’s weight is noticeable but manageable. Thanks to the wide bar and reasonable steering geometry, you can still navigate tight turns or weave through obstacles, though it will never feel as flickable as a lightweight hardtail.

At medium and high speeds, the bike feels planted. The long wheelbase and fat tires give you confidence in loose corners, and the suspension prevents harsh kickback from rocks or small drops. Under braking, the frame stays composed—there’s no sense of twisting or flexing.

The main handling compromise is that repeated quick direction changes (for example, slaloming through close obstacles) take more deliberate body input. Again, that’s expected for a 90-lb full-suspension fat-tire bike with a big battery and rack.

Brakes & Safety Features

Stopping a bike that can reach motorcycle-like speeds is serious business, and the Swift Horse Pro comes equipped accordingly. The 4-piston hydraulic disc brakes with 180 mm rotors offer strong, progressive stopping power. Compared to mechanical discs, the lever feel is smoother and requires less hand strength, especially on long descents. Many testers specifically praise the braking performance as one of the bike’s standout features.

The CST fat tires contribute decent grip on both pavement and dirt. On dry asphalt you can brake hard without immediately locking up; on gravel or wet surfaces you still need to modulate the levers, but overall traction is solid.

Lighting and visibility are another strong point. You get an 800-lumen headlight that’s bright enough for genuine night riding, not just “be seen” safety. Integrated rear brake and turn lights help traffic understand what you’re doing, and the lights are wired into the main battery so you don’t juggle extra cells.

Finally, the UL 2849 and UL 2271 certifications add an important safety layer around the electrical system and battery, addressing concerns about thermal events and electrical faults—especially relevant for riders parking indoors or charging overnight.

Controls, Display & Riding Modes

The cockpit is busy but intuitive. On the left, you get the control pad for changing PAS levels, toggling lights, and navigating the color display. On the right, there’s the Shimano shifter and thumb throttle. After a short learning period, most riders will find it easy to operate without looking down constantly.

The color LCD is bright enough to read in daylight and displays speed, PAS level, battery status, trip distance, and more. A neat touch is the built-in USB-C port, allowing you to charge a phone or GPS while riding.

NFC & lock features

One of the bike’s unique tricks is its smart locking system. You can “swipe to unlock” using an NFC key card or use a password to activate the bike—no physical ignition key needed beyond the battery lock. This is not a replacement for a proper U-lock, but it discourages casual joyrides and feels more secure than a basic on/off button.

Riding modes

The Swift Horse Pro offers five primary modes:

1. Manual mode – Motor off; ride it like a heavy, fat-tire bicycle.
2. Pedal-assist (PAS) mode – Five levels, from gentle support to full punch. Lower levels feel natural and efficient, while higher levels provide strong acceleration.
3. Throttle mode – Thumb throttle delivers power on demand up to about 20 mph.
4. Cruise control – Hold a constant speed without holding the throttle; handy on long, flat sections.
5. Walk mode – Low-speed motor assistance to push the bike up ramps or hills while you walk beside it.

The PAS tuning is clearly oriented toward power rather than subtlety. There can be a brief delay before assist kicks in (as is common with cadence-based systems), and the jump between higher levels can feel aggressive if you’re not ready for it. Experienced e-bike riders will adapt quickly; newcomers should start in the lower levels until they get used to the behavior.

Fit, Sizing & Adjustability

Freesky recommends the Swift Horse Pro for riders between roughly 5'3" and 6'5". The seatpost offers a good range of adjustment, and the handlebar height is set for a relaxed, slightly upright stance.

Taller riders in the 5'10"–6'3" range will likely feel right at home: there’s enough reach and saddle height to avoid cramped knees, and the wide bars offer good leverage. Medium-height riders around 5'6"–5'9" should also be comfortable once the seat is dialed in.

Shorter riders around the lower end of the range may struggle with the minimum seat height and the overall size of the bike. With fat tires and suspension, the standover and saddle positions are inherently higher than on a compact city bike. If you’re under about 5'4", it’s worth trying one in person if possible, or at least measuring your inseam carefully against the published geometry.

There is no step-through option here—this is a traditional high-top-tube mountain bike frame. Riders with limited mobility or knee issues may prefer a different model with a lower step-in height.

Assembly & Out-of-the-Box Experience

Like most direct-to-consumer e-bikes, the Swift Horse Pro arrives partially assembled, typically around 80–85%. The frame, motor, and rear wheel are already built; you’ll usually need to install the front wheel, handlebar, pedals, front fender, headlight, and possibly the rear rack.

Freesky includes basic tools and a printed manual, and there are online videos that walk through the process. Plan on 60–90 minutes for a careful home assembly if you’re reasonably handy with bikes. If you’re new to wrenching, it might be worth budgeting for a local shop to give it a once-over, particularly to fine-tune the hydraulic brakes and drivetrain.

The bike is heavy inside the box, so having a second person to help lift it out is a good idea. Packing protection is generally adequate; still, inspect for shipping damage before cutting away all the foam and zip-ties.

Once assembled, you’ll want to:

• Check tire pressure (they often arrive low).
• Verify that the brakes don’t rub and that the levers feel firm.
• Confirm the derailleur is shifting cleanly through all 7 gears.
• Fully charge the battery before your first longer ride.

What’s Included in the Box?

In the box:

• Freesky Swift Horse Pro electric bike (mostly pre-assembled)
• 48V 30Ah Samsung cell battery
• 48V charger (around 3A)
• Metal fenders
• Rear rack with integrated mounting points
• Headlight, turn signals, brake light
• Basic multitool and small hardware kit
• User manual and warranty information

Our take on the package

For the price, the accessory package is generous. You don’t need to immediately buy a rack, fenders, or lighting—they’re already there. The included tools are fine for initial setup but not a complete home-mechanic kit, so frequent riders may want better hex keys and a torque wrench. A heavy-duty lock and possibly a suspension seatpost are the only obvious extras to budget for.

Smart color display with NFC key and USB-C charging

How the Freesky Swift Horse Pro Compares to Alternatives

To put the Swift Horse Pro into context, it helps to look at a few popular alternatives in the full-suspension fat-tire space.

• Himiway Cobra Pro – Another full-suspension fat-tire bruiser with a mid-drive motor and high capacity battery. It offers excellent off-road traction and a different feel thanks to the mid-drive layout, but it typically costs more and doesn’t always match the Swift Horse’s sheer battery capacity at this price.
• Cyrusher Ranger / XF900-style bikes – These bikes also emphasize power and style with big motors and aggressive frames. They’re often similarly heavy and fast, but some models come with slightly smaller batteries or fewer safety certifications, making the Swift Horse Pro attractive if range and UL listings are priorities.
• Aventon Aventure 2 (hardtail) – This is a more refined Class-legal fat-tire commuter with thoughtful integration and better brand support, but it “only” offers a 750W motor and smaller battery. It’s lighter and more civil for city use, yet lacks the downright brute force and range of the Swift Horse Pro.

When to pick the Swift Horse Pro

Choose the Freesky if you care most about:

• Maximum power for long, steep climbs
• Very long range without carrying a second battery
• Full suspension comfort and fat-tire stability on mixed, rough terrain
• High payload capacity and included rack/fenders

When an alternative might be better

Look elsewhere if you:

• Need to comply strictly with Class 1/2 rules on shared paths
• Want a lighter, easier-to-carry bike
• Prefer a bike tuned more for polished urban commuting than off-road versatility
• Are shorter than about 5'3" and need a low step-through frame

Common Questions About the Freesky Swift Horse Pro

Final Verdict – Should You Buy the Freesky Swift Horse Pro?

Score: 8.6 / 10

The Freesky Swift Horse Pro is not trying to be all things to all riders. It’s a big, powerful, long-range fat-tire e-mountain bike that shines when the road turns steep, loose, or long. If you’re a heavier rider, live near serious hills, want to explore trails, snow, or beach sand, and hate worrying about range, this bike delivers a ton of value for the money.

You do need to be comfortable with its weight, its size, and the fact that its full performance potential sits beyond what many e-bike laws allow on shared paths. Shorter riders and those who mainly ride smooth city streets may be better served by a lighter, more conservative model.

But if your ideal weekend involves climbing fire roads, bombing back down with four-piston brakes at the ready, and rolling home with plenty of battery left in the tank, the Swift Horse Pro absolutely deserves a spot near the top of your list.
