I’ve examined a number of folding fats tire e-bikes. They’re one of the vital standard classes of low-cost e-bikes because of their mixture of go-anywhere design and compact kind issue, however I’ve by no means seen one fairly as odd-looking because the EUY K6 Professional.
That’s because of its novel folding design that encompasses a not often seen center-axle hinge to fold the bike in half. It’s bizarre. It’s wild. And I’m testing it out to see what it might do.
My first intuition is to fret a bit concerning the robustness of the design. Typical folding e-bikes use a reasonably tried-and-true design. That’s why most e-bike firms keep on with it.
Occassionally we’ll see attention-grabbing new folding designs, however that additionally generally results in surprising issues down the highway… like e-bikes breaking in half.
However the EUY K6 Professional felt pretty rugged with that beefy hinge taking over many of the width of the bike body.
Test it out in my video evaluate beneath, then preserve studying as we dive into the small print of this funky new tackle a folding fats tire bike.

An unusual design
At first blush, the characteristic record on the EUY K6 Professional feels pretty acquainted. A Class 3 e-bike with a 1,000W peak rated rear hub motor for a prime velocity of 28 mph (45 km/h)… it’s all fairly frequent today.
Components like hydraulic disc brakes begin to make my ears perk up, although the 160 mm rotors are a bit smaller than I’d wish to see. However as I begin to dig deeper, now I’m beginning to discover issues I actually like.

The complete-suspension design isn’t overly fancy, however there aren’t very many full-suspension folding fats tire e-bikes in the marketplace. Extra are popping up, however they’re the exception, not the rule.
The suspension right here is first rate up entrance, not fairly pretty much as good within the rear, but it surely’s tremendous for leisure driving and can forestall a random tree root from sending the saddle into your tail bone with catapulting pressure.
Persevering with across the bike, I’m liking it much more. A removable Samsung 48V and 25Ah battery for 1,200Wh of capability? Signal me up! They are saying I’ll rise up to 80 miles of vary on pedal help, however everyone knows that’s on tremendous low energy mode and with medical-grade helium pumping the tires as much as a rock exhausting stage of PSI. For us regular of us in the true world, 30-40 miles of vary on throttle continues to be going to be a lot better than a number of the main gamers with half the battery of the EUY K6 Professional.
Even the 8-speed transmission provides some worth for me.

However then there’s that folding mechanism, and that is the place issues begin to get bizarre. It permits that attention-grabbing, uniquely chunky body design, but it surely additionally has a wierd technique of operation.
There’s a thumb screw-style clamp underneath the hinge on the middle of the bike. You crank that sucker open such as you’re about to carry out upkeep on some municipal plumbing. As soon as it’s open far sufficient, the enamel disengage, and all the entrance half of the bike is free to swing round to satisfy the again.
The bike is now half as lengthy and twice as vast because it was once. It’s smaller, in a means. However it’s not fairly as compact as I’m used to seeing with folding e-bikes that characteristic hinges in each the middle of the body and on the handlebars.
With the EUY K6 Professional, the hinge appears to alter the form of the bike, however not make it that a lot smaller. I’m undecided it would slot in a typical automotive trunk this fashion, although it will in all probability slide simpler in to the again of an SUV with its lowered size.

So whereas the folding setup doesn’t appear so as to add all that a lot to the bike, the remainder of the EUY K6 Professional continues to be pretty attention-grabbing to me.
It’s comfy to trip, particularly with that large butterfly of a saddle cradling my tuchus and the tall handlebars giving me a pleasant upright driving place.
The highly effective rear motor and Class 3 speeds give me loads of efficiency, and I even love that I’ve received a whole fender and rack set, one thing that’s usually left off of full-suspension e-bikes.
I’ll dock a number of factors for the tail mild being independently battery-powered as a substitute of working off of the principle e-bike battery, particularly since 1,200Wh means there’s loads of battery to go round. The very last thing I would like is to be fishing round my junk drawer for spare coin cell batteries. However all in all, the characteristic record and efficiency are pretty on level.

A worth of $1,900 isn’t overly costly for the bike, particularly with twice the battery capability of most of its competitors. However it’s additionally not a surprisingly low worth, both. For my part, you’re partly paying for a very difficult folding mechanism that simply isn’t that obligatory.
I just like the attention-grabbing design of the body because it’s a departure from the boring dime-a-dozen folding e-bikes on the market, but it surely’s additionally a bit pointless for my part.
So whereas the bike works nicely, a part of me needs they’d simply constructed an attention-grabbing body for an e-moped with out going all folder on me. However hey, that’s why the e-bike market is so nice: With a whole bunch of fashions on the market, if this one doesn’t converse to you, then you definitely’re sure to seek out one that can.
