SASIKEIBIKE Y7 Review: A Blue, Moto-Styled Fat Tire E-Bike With Plush Suspension (and a Few Quirks)

If you’ve been eyeing the SASIKEIBIKE Y7 because it looks like a stealthy little enduro e-bike (with fat tires), you’re not alone. In person, it’s even more aggressive than it looks online—especially in that loud, attention-grabbing blue.

This is one of those rides that *looks* like it should be way more expensive and way faster than it actually is. But the big question is: does it feel good to ride day-to-day, or is it all style?

First Look: Moto vibes, fat tires, and a steel-frame heft

The Y7 has a distinctive “mini electric motorcycle” silhouette—frame shape, fairing-style front, long seat, and a low-slung stance. It turns heads.

The tradeoff is weight. This bike uses a steel frame, and I noticed that it’s heavy (around 140 lb). That matters if you’re carrying it up steps, lifting it onto a rack, or trying to shuffle it around a tight garage.

Ride Feel: Plush suspension is the headline

The biggest real-world takeaway from the first ride is comfort. The suspension is described as super plush, soaking up rough pavement and potholes in a parking lot without feeling harsh.

Front suspension: preload and compression adjustments are mentioned.

Rear shock: basic, with no obvious adjustments, but it looks like something you could upgrade later.

On broken pavement, the Y7 comes off as more comfort-cruiser than razor-sharp handler—and honestly, that’s probably what most riders want from a fat tire, moto-styled e-bike.

Steering & handling: Stable, but fat tires steer slower

The Y7 rolls on 20x4" fat tires (the walkthrough mentions 20x4; the later recap mentions 20x4.5). Either way, it’s a wide tire setup with a dual-sport style tread that leans more street than dirt.

You feel that width in the steering. It’s not twitchy—more planted and a little slower to lean than narrower-tire e-bikes. That can be a good thing for cruising, but it won’t feel like a nimble MTB.

Power delivery: Pedal assist hits fast, throttle lags

This is where the Y7’s personality shows.

Pedal assist feels immediate—and in higher assist levels, the bike can surge hard enough that you’ll want both hands on the bars and your balance set before it kicks.

The throttle, though, has a noticeable delay. In the ride, it’s described as a “one, two… then it kicks in” kind of lag. That’s the opposite of what many riders prefer—most of us want the throttle to be the instant-response control.

It’s something you can probably adapt to, but if you ride in traffic or do a lot of stop-and-go, that delay is worth thinking about.

Braking & traffic-ready lighting

The Y7 comes with hydraulic disc brakes and a 203 mm rotor is specifically called out in the walkthrough (front is shown; rear is also hydraulic). Braking impressions in the test were positive—“brakes feel really good.”

Lighting is also a standout for this category:

A large integrated headlight

Tail light with brake light function

Integrated front and rear turn signals

That signal setup is a real quality-of-life win if you’re mixing with cars—even if local legality depends on where you live.

Seat & ergonomics: Comfortable saddle, tall feel for shorter riders

The seat is described as well-cushioned and comfortable, with a planted “pocket” feeling due to its shape.

Fit, however, depends on your height.

I (30" inseam) notes it feels tall and a bit big.

A taller rider (around 6 feet) says they fit it really well.

If you’re shorter, expect more of a “one foot down” stop style.

Speed test notes: Fast enough to be fun, but the speedometer seems off

In testing, the bike ran over 30 mph. The YouTube description also states a top speed of 28 mph, so expect real-world results to vary depending on conditions and how the bike is set up.

One consistent point: the display speed readout didn’t seem accurate during the ride. It appeared to read higher than actual speed based on GPS/Dragy comparisons.

Battery access: Not a quick-release situation

The battery is housed inside the frame, and my test suggests it’s not designed for quick removal—you’ll likely need to remove screws to access it.

If you live in a cold climate or you need to carry your battery inside for charging, that could get annoying fast.

What We Like

Unique, aggressive styling that stands out from typical moped e-bikes

Plush suspension that smooths out rough pavement and potholes

Integrated turn signals front and rear (rare at this price point)

Hydraulic brakes felt strong in testing

Comfortable, cushioned moto-style seat

Things To Consider

Throttle response has a noticeable delay; pedal assist is more instant

Battery doesn’t appear to be quick-release (screw-access design)

Speedometer/display readings didn’t seem well calibrated

Heavy steel-frame build (around 140 lb) affects transport and handling off the bike

The aggressive “motorcycle look” may attract attention depending on local enforcement

Final Thoughts

The SASIKEIBIKE Y7 is one of those e-bikes that sells the fantasy a little—enduro frame vibes, fat tires, and a full lighting package—without being an uncontrollable rocket. It rides like a comfort-focused cruiser with enough speed to keep it fun, and the suspension is the star of the show.

If the throttle delay and battery access don’t bother you (or you’re willing to live with the quirks for the price), the Y7 feels like a surprisingly compelling option for riders who want that mini-moto look with real everyday ride comfort.
