Fluid Mosquito Review: The NEW Ultraportable Pocket Rocket

Fluid Mosquito


Meet the brand new Fluid Mosquito, which is by far the fastest ultra-portable scooter we’ve ever tested. The Fluid Mosquito is more portable than a Xiaomi m365, but almost twice as fast; more range than a Ninebot Max G30LP, but  10 lbs lighter. 

In this review, we test the Mosquito’s performance and ride quality against the world’s best ultra-portables and find out what it’s like to ride the fastest scooter you can take just about anywhere.

And if the Mosquito looks familiar, that’s because it’s manufactured to Fluid Freeride’s specifications by E-TWOW. E-TWOW are pioneers in ultra-portable electric scooters and have been around since 2013. Collaborations like the one for the Mosquito project are a common manufacturer/retailer arrangement for US and Canadian scooter brands. 

E-TWOW has included some branding on the features. Still, the specifications are all unique to Fluid Freeride, alongside after-sale support and an extraordinary warranty being offered for pre-orders of the Mosquito.

 Around here, we love scooters that challenge the status quo. For instance, who said a scooter can’t be both ultraportable, with a high top speed and extended mileage? Around here, we love scooters that challenge the status quo. For instance, who said a scooter can’t be both ultraportable, with a high top speed and extended mileage? If you’ve bought into that propaganda, you’re wrong! Meet the Fluid Mosquito–the fastest ultraportable scooter

FluidFreeRide and E-TWOW gave us precisely what we’d anticipated from their love child. They reimagined the scope of ultra-portable electric scooters by ensuring that theirs called for minimal compromises. 

The Fluid Mosquito does everything your regular commuter scooter will do and then some. It brings you best-in-class top speed, average range, high rider weight capacity, good braking, fast acceleration, and, can you believe it, exceptional hill climbing. All that from a 30 lbs electric scooter is quite the design feat.

The Mosquito electric scooter is here to reimagine the ultraportable electric scooter space. Our desire is to see pioneers like Segway with the AirT15 and Glion improve on their existing models and give us scooters that aren’t just easy to carry and store but can even dare to compete with midrange scooters.

Our Take: Fluid Mosquito

A successful Feat at Designing a High Top-Speed, Ultra-portable scooter

Best Fluid Mosquito Alternatives and Competitors

EMOVE Touring Vs. Fluid Mosquito

EMOVE Touring is a stronger hill climber, is quicker to  15 mph, and has a higher rider weight capacity. But it has a lower top speed, lower IP rating, and is  10 lbs heavier.

Unagi Model One E500 vs. Fluid Mosquito 

Unagi Model One E500  has less range and speed, but has a gorgeous design, incorporates materials like carbon fiber and magnesium, and is available with Unagi’s famous subscription model. 

Ninebot Max G30LP vs. Fluid Mosquito 

Ninebot Max G30LP has a shorter stopping distance and smoother ride, but the Mosquito essentially beats it in every other way and is  10 lbs lighter.

Is It Good for Bigger, Heavier Riders?

Does a duck quack? 

The Fluid Mosquito may be one of the tinier scooters we have, but by no means is it a slacker in carrying its weight. It is equipped with a 500W front motor with 700 W peak power and can haul riders weighing up to  265 lbs. It feels perfectly sprung for riders weighing between 140 lbs  to 200 lbs, but we ran tests with a heavier rider at  250 lbs, and he experienced no lag when trying out the scooter.

The deck is long to accommodate larger foot sizes, and the handlebar is adjustable to two heights 36 inches and 39 inches, which is accommodative for tall riders ensuring minimum slouching. The scooter is powered by a 460 Wh battery, which is enough to ensure heavier riders get enough thrill before running out of juice.

Fluid Mosquito Review

Performance Summary

Acceleration (0 to 15 mph)5.1 seconds
Acceleration (0 to 20 mph)8.1 seconds
Acceleration (0 to 25 mph)17.3 seconds
Top speed27.7 mph
Braking distance (15 to 0 mph)16.4 feet
Range16.6 miles
Hill climb14.5 seconds


The Mosquito has an average and smooth acceleration curve and accelerates from  0 mph to 15 mph in 5.1 seconds. This is quicker than all its peers, except for the  10 lb heavier EMOVE Touring that hits  15 mph in 3.9 seconds and the dual-motor Unagi that gets there in 4.4 seconds. 

The motor power comes on gradually, which is perfect for riders getting started on electric scooters.

Top Speed

This is where the scooter really shines. At  28 mph, the Mosquito has the highest top speed in the ultra-portable class of electric scooters. In the top speed vs. weight comparison, no other scooter comes close.

Here, the Fluid Mosquito shows off against scooters in its weight and performance class.

 At this speed, the Mosquito is even faster than some dual-motor electric scooters like the Mercane Widewheel Pro, with a speed of  27 mph. It also goes faster than the Kaabo Mantis 8 which is rated at 1000 W.

The scooter’s top speed is also regulated by different gear modes. The 5 different gear modes regulate the speed as below:

  • L1 =  5 mph
  • L2 =  10 mph
  • L3 =  16 mph
  • L4 =  24 mph
  • L5 =  no limit

Hill Climb

We love ourselves a good mountain goat, and the Mosquito is an excellent hill climber. The power to weight ratio is excellent for scaling hills, regardless of rider weight. It outperforms resident favorites like the Xiaomi m365 and the Segway Ninebot Max. However, the dual-motor Unagi poses significant competition on this front. The Mosquito maintained an average speed of  9 mph as it scaled our  200 ft, 10% grade test hill in 14.5 seconds, which for its weight is quite decent.


Our search for a scooter with excellent range per pound has not been easy. We like the Fluid Mosquito because it gives us range without demanding too many sacrifices on other fronts. The Mosquito is a rare occurrence of a high-speed, ultra-portable, and long-range scooter. The scooter has an incredible range of  17 miles on a single charge, facilitated by a 460 Wh capacity battery that charges in 5 hours. 

The Mosquito gave me plenty of warning during the range test before cutting off. For the first ⅔ of the test, it maintained  18 mph up fairly steep hills and mid 20’s on flat ground. At 30% battery, there was a noticeable drop in acceleration, and the max speed up steep hills dropped to  10 mph. When the battery meter hit 0%, I was still able to cover another  2 miles, averaging about  10 mph.

The scooter manages a better range than the ultra-popular scooter, Ninebot Max G30LP. Not to say that there aren’t others that perform better. For instance, the FluidFreeRide Horizon is a great alternative we can recommend. We have another one with one of the best tested ranges we’ve experienced, but  we can’t in any good conscience recommend that one.


The Mosquito is equipped with a triple braking system comprising a rear drum brake, rear stomp brake, and a front regen throttle brake. Combined, the regen and drum brakes will give you a stopping distance of  15 ft from  15 mph. The stomp brake is nice to have, but we think most riders are unlikely to use it since it’s not as convenient as just using the brake levers. 

Once you get comfortable with your scooter, we recommend adjusting the regen brakes as they are set to soft and might not be so effective. The soft settings on the regen have a braking distance of  21 ft. These settings ensure that you are not hit with an overwhelming stopping force that can result in skidding or getting thrown over the handlebars. 

Ride Quality

Unfortunately, there’s nothing to write home about the ride quality. The scooter is easy to ride, but there’s only so much you can do on a scooter designed for ultra-portability. The manufacturer’s priority was more on utility and reducing weight versus rigging the scooter with high-performance features. For instance, the scooter comes with small tires that are poor at rolling over obstacles. They are also solid, which means zero ride comfort.

The Mosquito is equipped with a basic front and rear spring suspension setup to tackle the issues that come with solid tires. The Front suspension is located at the bottom of the steering column, while the rear is located below the deck. The Mosquito’s full suspension does a good job smoothing out large bumps, but jitters from rough pavement still come through. The ride quality cannot be compared to a suspension + air-filled tires combination.

The Mosquito has relatively narrow folding handlebars. They’re just a little wider than the keyboard on a laptop, but you get used to them after a couple of miles.

The deck is surprisingly roomy, which is great for adopting comfortable riding positions. Also handy for long rides is that the Mosquito has cruise control, which engages after holding the throttle steady for 5 seconds. It disengages if you touch the throttle or the electronic brake. The scooter defaults to having the cruise control off, so it doesn’t catch anyone by surprise, but it’s easy to turn on in the P-settings. 

Fluid Mosquito Features


In case we haven’t mentioned it, the scooter is ultraportable. 

It weighs  30 lbs and doesn’t even need to fold down completely to occupy one of the smallest footprints we have on a folded scooter. The dimensions, when collapsed, are  13 inches x 6 inches x 42 inches. The possibilities of what you can do with an ultraportable scooter are endless, right down to carrying it with you on a first date and being completely out of sight.

The handlebars and the stem retract to reduce the space occupied when folded. And one of our best features is the perfectly balanced carrying strap accessory that has an ergonomic effect when carrying the scooter around on your errands.


The new bar for electric scooter aesthetics seems to be centered on unique and futuristic cockpit designs. Still, once in a while, we like to experience the classy, sporty installations like those typical of E-TWOW scooters. 

The middle section has a basic color 1.1 in² LCD that shows your speedometer, odometer, five battery bars, and ambient temperature. While riding in sunlight, the speedometer is easy to read, but the smaller numbers are best read in the shade or while standing still.

The handlebar ends are covered in rubber grips for ergonomic riding. The left side has a thumb-control for the front regen brake, while the right side has a thumb-throttle and a brake lever for the rear drum brake. 

Fluid Freeride’s standard P-settings give the Mosquito smooth throttle and brakes, making it easier for new riders to learn on. But it also has more aggressive settings for those of us who like to push the limits. The P-settings also allow you to set a zero start, EBS (electronic braking system) power (0-5, 0 being the lowest, 5 the highest), cruise control, motor lock, and change metrics.

The display console houses 4 buttons that control the electronic horn, display settings, power, headlight, and taillight. The horn is jarringly loud and can sound like a fire alarm. We advise against abruptly sounding the horn, as it comes off as an emergency-worthy sound that might scare pedestrians. 


The Mosquito electric scooter has a lighting profile that’s, well, adequate. The front LED headlight is high-mounted and provides sufficient lighting for the immediate path ahead. 

The rear taillight is mounted on the fender and doubles as a brake light. It is super tiny, and the braking function only activates for the regen brakes–but it’s better than nothing. 


We are not fans of solid tires, especially small solid ones. The Mosquito rolls on a pair of   8 inches x 2 inches solid tires, which is the smallest tire profile in Fluid’s line of scooters. The small wheels come at the cost of handling, but they are great for ultra-portability. Solid tires do have two advantages though, you’ll never need to check tire pressure, and you’ll never get a flat.


The last thing we expected from an ultraportable scooter was a roomy deck, yet here we are. The Fluid Mosquito’s deck gives you plenty of legroom with its 20 inch length. It is longer than that of the Ninebot Max and just a 0 inch shy of the performer Wolf King GT. It is always a cherry on top when you have room to shift your stance when riding an electric scooter.

Build Quality

The scooter came to life through a partnership between renowned scooter manufacturer E-TWOW and FluidFreeRide. Both are known for releasing some of the most reliable electric scooters. Models from the brands are known to ride thousands of miles without needing major repairs. 

These scooters are built for durability. They are modular and can be easily maintained at home in case something goes wrong. Fluid Freeride has an expansive dealership network, which means replacement parts are readily available when needed. The parts are also quite basic, meaning that repair can be performed by just about anyone–with the right instructions, of course. 

To add to that, the tires are solid and warrant no level of maintenance outside of regular checks for wear and tear.

The scooter has an IPX5 rating, which means it can sustain rides through light showers. Keep off muddy puddles as the manufacturer does not cover water damage under warranty. For The Mosquito, the fenders are a step up from predecessors whose owners constantly complained of rattling rear fenders. The solid fenders are good and excellent at keeping mud and debris off the deck and feet. 

The deck is covered in a silicone cover for standing stability. It also comes with a robust kickstand attached. 


The scooter is built to be safe for the rider and other road users. It comes with a horn, albeit a piercing one. The electric scooter is also fitted with a high-mounted headlight and standard tail/brake light that enhance night riding. The stem latch engages solidly to eliminate instances of accidental folding. 


The warranty is pretty standard. The Mosquito comes with a 12-month warranty. However, Fluid FreeRide is currently offering an additional year of warranty free for those who purchase on pre-order.

Fluid Mosquito: Review Conclusion

Who is the Fluid Mosquito designed for? The scooter’s design is great for beginners and smaller riders. Both classes of riders will enjoy the ultra-portability, ergonomic design, smooth and average acceleration, adjustable regen braking, safety features, and the adjustable stem that can be customized to suit different riders. Larger and more seasoned riders will definitely appreciate the good hill-climbing, high top speed, and above-average battery capacity.

But, like all electric scooters, the Fluid Mosquito is not for everyone. It is not the most feature-rich or cutting-edge design. acceleration is silky smooth, but the ride quality is not, and corner-carving could be better. The solid tires also get in the way of comfortable rides. That aside, this scooter is built for maximum utility. It is rapid, ultra-reliable, with a profile so small you can take it virtually anywhere. If that sounds like a scooter after your heart, then the Fluid Mosquito is for you.
