The Polarna M4 electrical bike could not look fancy, but it surely hides away much more e-bike than you cut price for. This quick and enjoyable off-roader even folds to make it simpler than ever to take a full-suspension fat-tire e-bike wherever.
Full-suspension fat-tire e-bikes aren’t uncommon, they’re simply often fairly costly.
We often see them begin effectively above $2,000 and go up shortly from there.
But at a value of simply $1,399, the Polarna M4 brings that full-suspension fatty goodness to the lots at a way more reasonably priced value.
Whether you want a fold-up fat-tire e-bike to drive to a close-by path community to your rides, otherwise you need to maintain an all-terrain e-bike in your RV for adventures at stops, or actually any motive that will have you ever on the hunt for a less-than-gigantic e-bike, the Polarna M4 appears to suit the invoice for high-spirited e-bike tomfoolery.
Take a gander on the e-bike in motion in my overview video beneath. Then proceed on for the remainder of my full overview.

Fat and foldy
The Polarna M4 does precisely what a fat tire e-bike is supposed to do: it rides over nearly every part.
While bigger 26″ wheels are the kings of all-terrain driving, the 20″ tires right here nonetheless do almost pretty much as good off-road, particularly whenever you maintain the stress down within the 10-12 PSI vary. Depending on how delicate the bottom is, you possibly can even go decrease.
When you’re again on the street (and utilizing a bit greater tire stress), the Polarna M4’s 750W continuous-rated motor makes use of each watt at its disposal to take you as much as almost 30 mph.
The firm claims that it reaches 32 mph, however after de-limiting the bike through the show I used to be largely hitting 28 or often 29 whereas driving on flat floor, with occasional spurts into 30 mph territory. Perhaps that they had the assistance of a tailwind after they quoted it.
The colour LCD display is simple to learn each through the day and at evening, and it truly appears fairly good. I’m so used to monochrome screens that colour shows usually nonetheless catch me off guard. It’s undoubtedly a sharp-looking display.
The headlight although, goes the opposite method. As good and vibrant because the display is, the headlight is a bit lackluster. It works, but it surely doesn’t actually mild your method that effectively. It’s a be-seen mild and is just about solely meant to let vehicles know that you just’re there. That’s tremendous on an e-bike, however for one thing like this that’s meant to journey off-road as effectively, a brighter mild might have been good.
The actual prize right here is the suspension. Not that it’s notably good high quality (I’d name it simply first rate), but it surely undoubtedly helps add to the experience. Without it, I’d have been driving a lot slower on trails. But because of the suspension, I used to be in a position to improve my velocity with out breaking my wrists or shaking my enamel out.
Again, it’s not going to win any awards within the high quality division, however the perceptible entrance and rear suspension make a world of distinction on rutted out or washboard terrain and helps clean out damaged asphalt or brick pavers as effectively.
When it involves braking, I used to be truly shocked to see hydraulic disc brakes included on the Polarna M4. Keep in thoughts, we’re speaking a couple of $1,399 e-bike right here, and hydraulic brakes often aren’t a part of the deal at this value level. But in some way they managed to present us full-suspension AND hydraulic brakes, in order that’s a win. I’d have preferred some bigger rotors than the fundamental 160 mm discs that we obtained, however I gained’t gripe an excessive amount of there. Plus I’m loving these forged wheels they’re mounted to, so that they managed to distract me with fairly spinning issues.
And forged wheels aren’t simply enticing trying, they take away yet another upkeep challenge: spokes. You’ll by no means fear a couple of spoke loosening up once more!
Also included are an enormous utility rack and a set of fenders. Both of these enhance day-to-day utilization of the bike by including additional utility.
They don’t do the load any favors, and the Polarna M4 is a heavy bike at almost 70 lb. But so long as you possibly can raise it, these commuter-style equipment like racks and fenders are an enormous assist.
Lifting the bike might be going to be necessary although, since that is in fact a folder. And that’s sort of the purpose – it folds up small to slot in a automobile.
Instead of needing a motorcycle rack on the again of your automobile, you might put the folded bike in a big trunk (assuming you possibly can raise it).
The folding mechanisms are fundamental and commonplace, nothing fancy there. It folds on the handlebars and in the course of the body. That’s how 95% of folding e-bikes work and it’s simply tremendous. It’s not space-age, but it surely works effectively. And it’s good and durable, which is precisely what you need on a motorcycle that you just’ll be bouncing over berms all day.
The solely draw back to the folding side is that you’re restricted on battery capability. The 615 Wh battery is appropriate, however not big. I’d say that’s solely barely beneath common for e-bike battery capability at this time.
The firm claims you’ll get 45 miles of vary, which is laughably optimistic. I used to be getting nearer to 20-25 miles on throttle-only driving. Granted, I used to be driving just about full-out, however nonetheless. Don’t anticipate to get near 45 miles until you’re slowing down and including some good pedal energy.
Despite utilizing throttle more often than not, I’d say the pedal help remains to be fairly comfy. The eight-speed transmission is a welcome improve over the numerous single-speed moped-style fat tire e-bikes on the market, in order that’s one other win. It additionally permits you to pedal pretty comfortably as much as the bike’s high velocity, which may’t be mentioned for all e-bikes.
Even so, I undoubtedly made liberal use of the throttle as a result of it’s simply a lot enjoyable to gun it on unfastened terrain like grass or dust, treating the M4 like my very own little folding dust bike.
It’s not as highly effective or rugged as a mud bike, and the suspension in fact can’t match, however I feel it’s effectively specced for leisure use.
As a enjoyable, quick, and highly effective folding fat tire e-bike, it suits the invoice properly. And there simply aren’t that many folding fat tire e-bikes on the market that supply full suspension.
At this value, I’d say the bike will get two thumbs up from me, besides that I’ve obtained one thumb almost perpetually mashed down on that throttle!
