Description

EMPOWER YOUR RIDE

The Polygon Siskiu TE-N is your all-mountain companion, ready to elevate your e-MTB experience on any trail. From singletrack adventures to technical climbs and flowy descents, this bike's balanced design, with 140/150mm travel, delivers both agility and confidence. Experience the freedom to explore further, ride longer, and conquer challenging terrain with ease.

BOSCH!

Think of the TE-N as the T8E, upgrading to the super desirable BOSCH Performance Line CX motor, delivering 85 Nm of smooth, quiet assistance for conquering any climb. The integrated 625Wh Bosch PowerTube battery offers ample range for all-day adventures, making the Siskiu TE-N one of the most affordable, trail-ready eMTBs equipped with the premium Bosch system.

FLIP-CHIP

The Siskiu TE-N features a flip-chip for personalized geometry adjustments. In the high position, run a mullet setup (27.5" rear wheel and 29" front) for a playful and agile ride on tight trails. Switch to the low position for optimized 29er (front and rear) performance on high-speed, chunky sections.

A TRUSTED BRAND

Polygon boasts over 30 years of experience and is known for offering high-performance bikes at competitive prices. The Polygon Factory Racing Team features top-100 enduro athletes who have rigorously tested and developed the Polygon range of eMTBs, with the Siskiu TE featuring as their favourite training tool. Rest assured, the Siskiu TE is finely tuned for performance, durability, and pure riding enjoyment.

ROCKSHOX SUSPENSION

Experience a plush and controlled ride with the burly RockShox Lyrik Select fork and piggyback-equipped Super Deluxe Select+ rear shock providing fade-free performance on long descents.

ULTIMATE STOPPING POWER

Confidently tackle steep descents with the powerful Magura MT7 hydraulic disc brakes with 200mm rotors. Often regarded as the most powerful brakes on the market, the MT7 is the perfect choice for handling the extra weight of any e-MTB.

WIDE RANGE AND RELIABLE

Experience smooth and precise shifting with the SRAM Eagle 1x12 drivetrain, upgraded with a GX Eagle derailleur for enhanced performance. The wide-range 11-50T cassette ensures you have the right gear for any terrain, from steep climbs to fast descents.

SRAM UDH

The Siskiu TE-N is equipped with a SRAM Universal Derailleur Hanger (UDH), a standardized and readily available component. This means less downtime in the event of a crash and a hassle-free experience getting back on the trails.

Assembly

Your bike needs minor assembly before riding; use the tools and videos included.

As a guide, it'll take 10-40min depending on whether you're an experienced bike assembler or have little to no mechanical experience.

Side Note: Your cables will stretch during the initial bed-in period and must be adjusted by an experienced mechanic around 150km of riding.

Nice bike

I purchased this e-MTB for my gf so she can ride with me. I have an human powered MTB. The weight does not seem to be a problem and it’s playful in the mullet form. With 4 modes, you want easy, use more power. You want a workout, use less power. My legs still feel like jelly when I finish riding. I’m not fond of the magura brakes. I’ve always heard great things abt the brand, but I just cannot get them to grip very well. I have sram brakes on my 3 other bikes, YouTube was helpful. I have ridden it more than she. lol Go figure. It’s fast and fun. I can go 2-3x times further burning more calories and love flying up climbs. The suspension is excellent. I’ll be swapping out the transmission to AXS. Overall good fun bike.

Wow, this bike is AWESOME!

I've been riding a Polygon Siskiu T8 for several years and I love it. When I realized the Polygon Siskiu TE-N is basically the eBike version of my analog bike, I went for it! Riding eMTB is a totally different sport but it feels much more familiar on a bike with similar geo to what I'm used to riding. The shifting needed a little work out of the box, but otherwise the bike was in good shape for riding. I love Polygon bikes and their eBikes don't disappoint either. This bike rides amazing and the value for cost is unbeatable in my opinion. I highly recommend!
