Mini 4 Pro

About

If you have been lurking in the electric scooter community for any length of time, the name "Minimotors" likely commands a certain level of respect. They are the Korean heavyweights behind the legendary Dualtron series-monsters of the industry known for tearing up tarmac. But what happens when that high-performance DNA is distilled into something you can actually carry onto a bus? You get the SPEEDWAY Mini 4 Pro. This scooter is widely regarded by enthusiasts as the ultimate "wolf in sheep's clothing." It doesn't look like a futuristic spaceship; it looks like a practical, industrial tool designed for one purpose: getting you from point A to point B significantly faster than the rest of the bicycle lane.

The philosophy behind the Mini 4 Pro is a fascinating study in compromise and optimization. Most scooters in the lightweight category suffer from "anemic motor syndrome"-they struggle up hills and top out at a leisurely jogging pace. Conversely, high-performance scooters usually weigh as much as a small boat anchor. The SPEEDWAY Mini 4 Pro sits squarely in the Goldilocks zone. It was designed to offer the torque and acceleration of a performance vehicle while maintaining a form factor that fits under an office desk. It is a machine built for the urban jungle, prioritizing raw utility and power-to-weight ratio over flashy aesthetics or unnecessary gimmicks.

Positioned as a premium commuter, this scooter appeals to the rider who has graduated from rental scooters or entry-level 250W models and is craving something with a bit more "fizz." It is not a toy; it is a legitimate personal electric vehicle. The design language speaks to durability and function, utilizing an aluminum alloy frame that feels substantial despite its manageable weight. It bridges the gap between the casual last-mile solution and the hobbyist performance machine, making it a darling of the community for those who want reliability without needing a gym membership just to lift their ride.

Safety

When you are dealing with a scooter capable of hitting speeds around 45 km/h, safety stops being a marketing buzzword and becomes a critical daily concern. The SPEEDWAY Mini 4 Pro employs a hybrid braking system that requires a bit of explanation to truly appreciate. On the rear wheel, you have a mechanical drum brake paired with an electronic regenerative brake. Enthusiasts often debate the merits of drum versus disc brakes, but for a daily commuter, the drum brake is a stroke of genius. It is enclosed, meaning it is largely immune to dust, water, and road grime, requiring significantly less maintenance than exposed disc rotors. While it might lack the immediate "bite" of a hydraulic disc, it provides consistent, reliable stopping power that doesn't fade easily.

The "secret sauce" of the safety system, however, is the regenerative braking with ABS (Anti-Lock Braking System). This isn't the ABS you find in a car, but an electronic modulation system that prevents the wheel from locking up and skidding during a panic stop. When you engage the brakes, you can feel the electronic system pulsing-a sensation that can be startling to new riders but is reassuring once you understand it. It keeps the scooter stable and straight when you need to stop in a hurry on a slick surface. Furthermore, the regenerative aspect pumps a small amount of energy back into the battery, which is a nice efficiency bonus, though its primary benefit is saving wear on the mechanical brake pads.

Visibility is another key pillar of safety, and the Mini 4 Pro comes equipped with dual front and rear LED lights. The rear lights also function as brake lights, flashing to alert traffic behind you when you are slowing down. However, a common observation in the community is that the low mounting position of the lights-embedded in the deck-is great for illuminating the patch of road directly in front of you, but perhaps less effective for being seen by SUVs. Many safety-conscious riders opt to add an aftermarket light to the handlebars for better eye-level visibility. Stability at speed is surprisingly good for a scooter with small wheels, thanks to the tight construction, though riders are always advised to keep both hands on the bars, as the small tire diameter means potholes demand your full attention.

Performance

This is the section where the SPEEDWAY Mini 4 Pro truly shines and separates itself from the sea of generic commuter scooters. Under the hood-or rather, inside the rear wheel-sits a BLDC hub motor that is often rated at 500 W nominal, but don't let that number fool you. The peak power output screams up to 1 360 W. In the world of electric micro-mobility, peak power is what you feel when you smash the throttle at a green light. The acceleration is punchy, immediate, and undeniably fun. It has enough torque to induce a bit of wheel spin if you aren't careful with your weight distribution, a characteristic that brings a smile to the face of any adrenaline junkie.

Top speed is a major selling point here. While many competitors are electronically capped at 25 km/h to meet strict regulations, the unlocked international versions of the Mini 4 Pro can reach speeds of up to 45 km/h. Riding at this speed on 8-inch wheels is an exhilarating experience that borders on terrifying if the road surface isn't perfect. It transforms a 30-minute commute into a 15-minute blast. You aren't just keeping up with cyclists; you are overtaking them with ease. The throttle response is managed by the ubiquitous "EYE" trigger throttle (or similar variants depending on the batch), which allows for customization of acceleration curves and power limits via the P-settings, letting you tame the beast if you just want a chill cruise.

Hill climbing is the nemesis of most lightweight scooters, often reducing riders to the "kick of shame" on steep inclines. The Mini 4 Pro, however, attacks hills with a vengeance. With a climbing grade ability of around 27% (depending on rider weight and battery level), it handles urban overpasses and steep driveways without breaking a sweat. Community feedback consistently highlights this hill-climbing prowess as a major reason for choosing this model. Where a standard rental scooter would stall, the Mini 4 Pro powers through, maintaining a respectable 20-25 km/h even on significant gradients. It gives you the confidence to explore hilly neighborhoods without range anxiety or the fear of stalling.

Design

The design aesthetic of the SPEEDWAY Mini 4 Pro can best be described as "industrial functionalism." It doesn't have the smooth, flowing lines of some modern lifestyle scooters; instead, it looks like a piece of precision machinery. The frame is constructed from a robust aluminum alloy, giving it a solid, rattle-free feel (mostly) that inspires confidence. The deck is wide enough to accommodate a comfortable stance, though not expansive. One of the standout design features is the telescopic stem and folding handlebars. This allows the scooter to shrink down to an incredibly compact size, making it one of the few high-performance scooters that can genuinely fit into a crowded train carriage or the trunk of a compact car without playing Tetris.

The folding mechanism is a point of frequent discussion within the owner's community. It uses a lever-based system that locks the stem into place. When new, it can be incredibly stiff-sometimes requiring a firm stomp to engage or disengage. While this might seem like a nuisance, seasoned riders will tell you that a stiff folding mechanism is infinitely better than a loose one. A tight latch means no stem wobble at 40 km/h, which is critical for stability. Over time, it breaks in, but it remains a secure, heavy-duty locking system that feels far safer than the flimsy latches found on cheaper alternatives.

Another unique design choice is the wheel setup. The scooter features an 8-inch pneumatic (air-filled) tire on the front and a solid rubber tire on the rear. This hybrid approach is a calculated design decision. The front air tire provides grip and steering confidence, absorbing the initial impact of bumps. The rear solid tire, which houses the motor, eliminates the possibility of a rear flat tire-which is notoriously difficult to change on hub motor wheels. While this design choice prioritizes reliability and low maintenance, it does have implications for ride comfort, giving the scooter a distinct, somewhat rigid character that connects you directly to the road surface.

Comfort

Let's have an honest conversation about comfort. The SPEEDWAY Mini 4 Pro is a "compact" scooter, and with that comes certain physical realities. The suspension system is a dual setup: a spring suspension in the front and a dual-spring air shock system in the rear. On paper, this sounds luxurious. In practice, it is effective but firm. The suspension does a commendable job of taking the edge off sharp impacts, like sidewalk cracks or manhole covers. It prevents your teeth from rattling out of your head, which is more than can be said for scooters with no suspension at all.

However, the ride quality is heavily influenced by that rear solid tire. Because solid rubber has zero give compared to air, the rear suspension has to do all the work. On smooth asphalt, the ride is sublime-gliding and stable. But on cobblestones or rough, pitted roads, you will feel the vibrations traveling up through the deck and into your legs. It is not a "magic carpet" ride; it is a sporty, connected feel. Long-time owners recommend bending your knees slightly to act as a secondary suspension system. For commutes under 10 km, it is perfectly comfortable. For marathon rides of 20 km or more, you might start to feel some fatigue in your feet due to the vibration.

The standing position is quite ergonomic for a scooter of this size. The handlebars are height-adjustable, a feature that is becoming increasingly rare on modern scooters. This allows riders ranging from 150 cm to over 190 cm to find a comfortable riding posture without hunching over. The deck length is sufficient for most shoe sizes, though riders with very large feet might find themselves adopting a stricter "skateboard" stance. The grips are basic rubber but can be easily swapped for more ergonomic mountain bike grips if you want to reduce hand fatigue on longer journeys.

Range

Range anxiety is the enemy of the electric vehicle owner, and the SPEEDWAY Mini 4 Pro fights back with a substantial battery pack. Depending on the specific sub-model, you are looking at a 48 V system with capacities typically ranging from 13 Ah to 16 Ah (often using high-quality Panasonic or LG cells in the "Pro" versions). The manufacturer claims a maximum range of up to 55 km. As an independent journalist, I must tell you: take manufacturer range estimates with a grain of salt. These are usually tested with a lightweight rider, on a flat indoor track, at a slow constant speed.

In the real world, where wind exists, hills are plentiful, and you are likely riding at full throttle because it's fun, the range is different but still impressive. Community reports suggest that a rider weighing around 75-80 kg can realistically expect between 30 km and 40 km of range on a single charge while riding in a mixed style (some full speed, some cruising). If you are heavy on the throttle and climbing lots of hills, expect closer to 25-30 km. This is still excellent for a scooter of this weight class. It means you can commute 10-15 km to work, charge it there (or not), and ride home with plenty of juice to spare.

Charging time is standard for the industry, taking approximately 6 hours to go from empty to full with the standard charger. This makes it easy to top up overnight or during a workday. The voltage sag-the phenomenon where the scooter feels less powerful as the battery drains-is present but manageable. The 48 V system maintains good "pep" until you get down to the last 20-30% of battery, at which point the controller will limit power to protect the cells. It's a reliable system that doesn't leave you stranded unexpectedly, provided you keep an eye on the voltmeter.

Use and Practicality

The SPEEDWAY Mini 4 Pro is the definition of a "practical daily driver." Weighing in at approximately 16 kg, it sits right on the threshold of portability. It is light enough that most adults can lift it with one hand to carry it up a flight of stairs or hoist it into a car trunk. However, it is heavy enough that you wouldn't want to carry it for a kilometer. The balance point is good, making it less awkward to carry than some lighter but poorly balanced scooters. For the urban dweller living in a walk-up apartment, this weight is a manageable trade-off for the performance you get.

The folding handlebars are a game-changer for commuters who use public transport. When the stem is collapsed and the handlebars are folded down, the scooter becomes a very narrow, compact package. You can slide it under the seat on a train, tuck it into a luggage rack, or store it under your desk at work without tripping your colleagues. This compactness is one of its strongest selling points over larger performance scooters which often have wide, fixed handlebars that snag on everything.

In terms of daily usability, the scooter is robust. The IP54 rating (often cited, though always check your specific manual) implies resistance to dust and splashes, meaning a light drizzle or a wet road won't kill it, but it is not a submarine-avoid deep puddles. The rear drum brake is low maintenance, meaning you won't be constantly adjusting calipers. The solid rear tire means you will never be late to work because of a rear puncture, which is the most common and annoying maintenance issue on e-scooters. It is a "grab and go" machine that respects your time.

General Assessment

The SPEEDWAY Mini 4 Pro has achieved a sort of "cult classic" status within the electric scooter community. It has been around long enough to be thoroughly battle-tested, and the verdict is overwhelmingly positive. Owners love it because it punches above its weight class. It offers the thrill of a high-performance scooter without the bulk or the exorbitant price tag. It is often described as the perfect "second scooter"-the one you buy after you realize your entry-level scooter is too slow, but before you decide to spend thousands on a racing machine.

The consensus is that while it isn't perfect-the ride can be harsh, and the design is a bit dated compared to the sleek new models from other brands-it is incredibly reliable and fun. The "fun factor" cannot be overstated. There is a raw, mechanical joy in riding the Mini 4 Pro that is sometimes lost in the overly refined, software-limited scooters of today. It feels like a machine you control, not a gadget that controls you.

However, potential buyers should be aware that this is a scooter that benefits from a "hands-on" owner. Like any high-performance mechanical device, it benefits from occasional bolt tightening and check-ups. The community support is massive, with endless forums, videos, and guides on how to maintain, modify, and repair it. If you are willing to engage with the machine, it will reward you with thousands of kilometers of reliable service.

Who Is This Scooter For?

The SPEEDWAY Mini 4 Pro is the ideal match for the pragmatic urban commuter who values time and efficiency. If you have a commute that involves a mix of bike lanes and roads, and perhaps a train ride, this scooter fits the bill perfectly. It is for the rider who needs to climb hills that would defeat a lesser scooter and who wants the power to merge safely with traffic when necessary. It is perfect for someone who has limited storage space at home or work but refuses to compromise on speed and range.

It is also a fantastic choice for the heavyweight rider (up to 100-110 kg). Many lightweight scooters feel sluggish under heavier loads, but the high-torque motor of the Mini 4 Pro handles extra weight with surprising grace. It won't be as fast as with a light rider, but it won't give up. It is also great for the DIY enthusiast who wants a platform that is easy to work on, with parts that are widely available and a design that is easy to understand.

Conversely, this scooter is not for you if you are looking for a cloud-like, ultra-comfortable ride on cobblestones-look for something with large pneumatic tires front and back for that. It is not for children or inexperienced riders; the throttle response and top speed can be dangerous without proper respect and protective gear. And if you need a waterproof scooter for riding in heavy downpours daily, you might want to look at models with higher IP ratings, as the Mini 4 Pro prefers drier climates.

Community Feedback - Pros

• Power-to-Weight Ratio: Users consistently praise how fast and powerful it is for being so light (16 kg).
• Hill Climbing: Frequently cited as a beast on inclines, easily outperforming standard rental scooters.
• Compact Folding: The folding handlebars and telescopic stem are loved for making it easy to store on trains and under desks.
• Reliability: Long-term owners report thousands of kilometers with minimal issues, citing the motor and controller as bulletproof.
• Zero Rear Flats: The solid rear tire is celebrated for eliminating the most difficult tire change, providing peace of mind.
• Acceleration: The torque is described as "zippy" and "thrilling," making traffic navigation easy.
• Braking System: The regenerative braking is effective and saves brake pads, with the ABS adding a layer of safety.
• Customizability: The P-settings in the display allow riders to tune the performance to their exact liking.
• Maintenance: Drum brakes and solid tires mean very little active maintenance is required compared to disc/air setups.

The most praised aspect of the SPEEDWAY Mini 4 Pro is undoubtedly its performance per kilogram. Riders love that they don't have to lug around a 30 kg behemoth to get decent speed and hill-climbing ability. It hits a "sweet spot" that very few other scooters manage to replicate, making it a favorite for people who actually have to carry their scooter as part of their commute.

Community Feedback - Cons

• Harsh Ride: The solid rear tire transmits vibrations from rough roads directly to the rider; it's not great on cobblestones.
• Stiff Folding Mechanism: New units often have a very stiff folding latch that requires significant force to operate until broken in.
• Low Headlight: The deck-mounted headlight is considered too low for seeing far ahead or being seen by cars.
• Single Motor: While powerful, some users wish for a dual-motor version for even better traction on wet leaves or steep hills.
• Handlebar Play: Some users report slight wobbling or "play" in the handlebars that requires tightening or shims to fix.
• Dated Display: The trigger throttle display is functional but looks old-fashioned compared to modern integrated screens.
• Brake Adjustment: The drum brake may need occasional cable tightening to maintain optimal bite.
• Small Wheels: 8-inch wheels are susceptible to getting caught in large potholes, requiring vigilant riding.

The most common complaint revolves around ride comfort on poor surfaces. The trade-off for the puncture-proof rear tire is a ride that can be jarring on anything other than smooth tarmac. Users often advise new buyers to check their local road conditions; if your commute is full of potholes and bricks, the vibration might be a deal-breaker. However, on smooth city streets, this complaint largely disappears.

Value for Money

At a price point of approximately 409 EUR, the SPEEDWAY Mini 4 Pro represents an absolutely staggering value proposition. Historically, scooters with this level of performance-48 V systems, 45 km/h speeds, and Minimotors engineering-have retailed for significantly more, often pushing towards the 800 EUR to 1 000 EUR mark. Finding it at this lower price point suggests it is an incredible bargain, likely due to it being a mature model in the market.

When you compare it to other scooters in the 400-500 EUR range, you are typically looking at 350 W motors, 25 km/h top speeds, and smaller batteries. The Mini 4 Pro completely obliterates these competitors in terms of raw specs. You are essentially getting "Pro" level performance for an "Entry-level" price. It is a rare case where you are buying into a premium brand's ecosystem for a budget cost.

Is it worth the investment? Without a doubt. Even if you have to spend a little extra on better lights or a handle grip upgrade, the core mechanical package is worth double the price. It is a scooter that will outlast and outperform almost anything else you can buy with this amount of money. It is a smart financial move for a commuter looking to replace a car or public transport pass.

About the Brand

SPEEDWAY is a brand line produced by Minimotors, a South Korean company that is practically royalty in the electric scooter world. Founded in 1999, Minimotors has been pioneering personal electric mobility for decades. They are best known for their flagship "Dualtron" brand, which essentially invented the high-performance, dual-motor scooter category. The SPEEDWAY line was developed to offer that same engineering prowess in a more accessible, single-motor, commuter-friendly package.

The reputation of Minimotors is built on power and durability. They don't make toys; they make vehicles. Their controllers and motors are legendary for their ability to handle high currents and abuse. When you buy a SPEEDWAY, you are buying into a lineage of racing and performance. This heritage is evident in the Mini 4 Pro's aggressive acceleration and robust frame.

Customer service and support for Minimotors products are generally excellent, largely because of the massive global distributor network. Unlike generic unbranded scooters, you can easily find spare parts, upgrades, and authorized service centers for SPEEDWAY scooters in most major cities and online. The community of owners is vast, meaning if you ever have an issue, there is likely a YouTube tutorial or a forum thread already dedicated to fixing it. If you are interested in high-performance mobility, you should definitely check out the SPEEDWAY brand page for more of their lineup.

Known Alternatives

While the SPEEDWAY Mini 4 Pro is a fantastic machine, the electric scooter market is crowded with competitive options. If you are shopping around, you might want to consider the SWAGTRON GlideXPro. This is often seen as a more budget-conscious alternative. It generally offers lower top speeds and range compared to the Speedway, but it is often lighter and even more portable, making it a strong contender for those with very short "last-mile" needs who don't need the highway-grade power of the Mini 4 Pro.

Another modern competitor is the NAVEE V25i Pro. Navee has been making waves with sleek designs and innovative folding mechanisms. While the Speedway is an industrial powerhouse, the Navee focuses more on modern aesthetics, app integration, and a user-friendly experience. It might not match the raw torque of the Speedway, but it often offers a smoother, more refined ride that appeals to the tech-savvy commuter who values style and comfort.

For those looking at different price points or regional availability, the ISCOOTER W8 and SENCOR SCOOTER S60 are worth investigating. These models often compete in the mid-range commuter segment. The MEARTH S is another notable mention, particularly popular in specific markets like Australia, known for its swappable battery system which offers a different kind of range flexibility compared to the fixed battery of the Speedway. Each of these alternatives offers a slightly different balance of speed, weight, and comfort.
