2020 Polygon Siskiu D7 Dual Suspension Mountain Bike from BikesOnline 

Dang Kevin you just gave this bike the Kev central effect now everyone wants one

I'm so happy about this! Thank you!!! I've been eye balling these for some time!

While I've never heard of this brand, it is refreshing to see that making a budget-priced full-suspension bike that is actually viable is possible. Hopefully, some of the bigger brand companies take note, and follow suit.

The best bike reviews on RU-vid. Hits all the major points I'm interested in and just long enough.

The space on rear triangle is for 29 wheels, propably to keep the price low they use the same rear triangle for all wheel sizes.

“It started to sound like math so I zoned out”😂😂😂

I'm late on the polygon train but I just bought myself the 2021 polygon siskiu d7 dropper post edition 29er with large frame today. Its a pretty substantial upgrade for me since I have been riding my mongoose xr pro 29er for the last 6 years. Last year, I upgraded my xr pro as you did (albeit with a couple better components) but I absolutely love my mongoose now. Anyway, I'm a super huge fan of your channel so thank you for all the mongoose vids (and all of the other big box store builds you've done). It made me feel good to know I wasn't the only fan of the xr pro. I'm sure I will love my new polygon once it ships in October but I won't forget about my xr pro. Its been with me through thick and thin, and a couple of knarly accidents to boot. Again, thanks for the reviews and for being an advocate for all of us budget minded folks. Stay safe and God Bless.

that's my next budget banger ! just got the Axum yesterday !! Thnaks foe all your hard work Kev!!

I bought one of these thanks to this review. I can confirm that there is much less space between the medium frames I got and the tire since I went with the 29" tires. To add to his review... I have done a decent amount of drops and jumps with my bike, it has zero issues with anything I have thrown at it so far. Drops go from small rock drops to a 3-4 foot wooden drop to mostly flat. I've done a few jumps some landing to flat and some not. None of this has ever pushed the ring off the rear shock. I'm 195-200lbs. If you do get this bike and run it on any rocky terrain do yourself a favor and run the tires at 25psi max as I got 3 flats running at 30psi. Note: they did send me the bike with contaminated brake pads as they assemble and test the bike before sending it to you and no one told the tester to clean the shipping gunk off the discs first.

Incredible, I'd been searching your channel and several others for reviews on Polygon bikes. Just last night I ordered the D5, very basic specs on it but good for the money and looks great! Just hoping it rides as good as it looks. I'm a new subscriber to your channel and really appreciate all the info you bring to us that are new to biking!

Couldn’t believe my thoughts. I was expecting the 1 by Walmart bike instead of something so sweet like this one.

This is a very good bike review. Easy enough for beginners to understand and it goes into depth of a lot of things advanced riders may be looking for in a bike. 👍🏾

Great review Kev! Glad to see you back out on the trail!

Whoa I never clicked so fast, I bought this bike in December after shopping for months and even testing an Orbea hardtail for a week. This Bike is superb for the cost, I've only changed the grips and pedals. I'm really enjoying this bike, it is definitely an entry level full suspension, which is what I wanted but most bike shops here started at 2 grand or more. I think this bike is built for people who want to trail ride and hits the bumps and small jumps, I wouldn't go risking life or limb on it. Oh and thanks kevcentral, it was you that got me back into MTB, I took a hiatus when we had kids, now I'm old and on a budget, but mostly old.

I was just looking at this bike. I’m 50 and about to start riding. I think I’ll look at the 29 being I’m 6’2 and 225. Thanks for the review.

Finally I've been waiting for an actual review on this bike

Oh wow, i was thinking of buying this as my next bike and boom, kev makes a review for it. Perfect timing

Very cool bike. This is the first time I've heard of the brand, hopefully you'll cover more of them in the future. Looking forward to the next video. Keep up the good work.

Now I think you should review the D5. This was a fantastic well made video! I would love to another one with Siskiu D5.

I've been looking at this bike actually with the dropper seat. Glad to see others checking it out. Because of the spec and cost looks like a solid fit for a budget upgrade. I'm currently on a Gt Verb Elite. Not to say nothing bad about the GT other than it being very XC. I find myself wanting more slack in the front especially on the descents. My goal is to make a purchase for my birthday in April until then I'll continue to shop around. Enjoy your content and hope to see more like this! Keep up the great work!

As if I need any more pressure to buy one of these. They’ve been targeting me with ads on Facebook and Instagram. Heavily lol

I bought a polygon Xtrada 6 29er hardtail last month and I LOVE it!!! Great bike and company!

I'm out of the loop on bikes in general, however this bike looks way more advanced than anything I've ever ridden!😆 As always great review 👍

Another great review. Haven't heard of Polygon before but it's a nice looking bike and well specced for the price.

Great review! You are so thorough. Nicely done.

The D7 comes with 29” wheels on the Large and XL sizes. I was originally looking at this exact bike but for the slight price increase going to the T7 I think it’s a better buy and am planning to pick one up hopefully soon.

Been in my shopping cart for a while, almost pulled the trigger , but only medium size available. Need xl. Awesome review. Thankyou Kev

Never heard of this one but I’m vvveeeeerryyy curious. Thanks for the review.

Been on a Polygon T6 since Dec 2018. Got the bike through a rep of theirs so really didn't get warranty support which I could use but their US importer was going to go out of his way to help me if really wanted super good peeps. Over all I have upgraded my brakes TRP Trail SLs or Quadiems, Sped Precision carbon wheels, Eagle cassette, XTR 2x11 and Spank Vibrocore handle bars, Fox transfer with kashima dropper and soon going DVO shocks XTR cranks and this bike will keep me going for about another 5-8 years+ very good base to start on for people. I am a ex DH rider speaking of X Fusion I was their first USA DH racer in the 2000s and know their engineers respect riders feed back and have built what i feel is a top 3 MFG for shocks world wide since I have been around with them over 20 years. You pointed at the handle bars as a issue 780 are for people who are more aggressive and want to grind up and down. Someone who wants to blast downhill as fast as they can on a 120, 130, 140 like a 160-170 enduro bike. Longer chain stay also help with that factor and like my bike from 2017 mud clearance is a issue for me but not anymore on the 2020s. If you look at their sponsored riders many of there are playful type riders if you keep riding their bikes and find their limits you will see they all have that focus on the fast DH. My T6 with 2.5/2.4 Minion DH casing tires at 140mm front and back eats rock gardens up and have zero issues. I trust this bike 110% give it the respect and it gives it all back 10 fold. If it was easier to get in the USA I would probably get one again.

I know you have fun from bikes but is fun is getting home from work and watching your new vidoe.

I just picked up the Xtrada 8.0, should be delivered tomorrow. Polygon seems to be an amazing value. Awesome channel, btw!!!

I own one, bought last November 2019. Love it!

Most of us in our late 30s hailing from Southeast Asia will remember a time when Polygon was known for their cheap steel bikes. They have certainly come a long way.

Finally. Polygon bikes are super hard to come by outside of Australia, so I'm glad they're finally getting around and being reviewed

I've been watching this bike for months. Seems like the best buy for the price.

I love your ‘reviews’, on high end parts. To the point and from a bike lovers point of view. - I have an S-Works Epic to a beach cruiser my neighbor found in the dumpster. Not as much as you however. I think everyone that watches your channel is looking for more enlightenment and insight for they’re future cycling venture.

I recently started to look into bikes. One vid took me to the mongoose pro that led me to all of the reviews of it and then the Walmart brands and then here lol. So many more to go but now with the knowledge and the eye opener to what to look for in a bike I may say my pallete is slowly I creasing lol. Thank you for doing this. And this is a sweet bike for the price.

Yeah i own a Polygon Premier 5 2019 model and its working great for casual riding or commuting

“It started to sound like math so I zoned out”, best line of all time. Great video just bought this bike and hope to love it.

I agree with Alex, the ads are non stop lol I'm so glad you did a review on this bike, I actually think its a good looking bike. Add some gum wall tires and you have a looker. This review has me on the fence, I love 27.5 hard tails because they are nimble but I'm still intreagued by the price. Thanks Kev!

I own the Trid, just got it about a month ago. The X-fusion air shock is great and works well with big drops and jumps. The bike did come with a weirdly large front rotor for the brakes but other than that the bike is amazing! And bikes online was great with sending it all the way to Florida in just 4 days! Also love your channel keep it up! Maybe take a trip to central Florida for a different type of riding.

Thank you for the review. I'm a trek marlin owner and have wanted a full sus since about a month after I bought my marlin. Been looking at this bike from day one. But there are no proper north American reviews until today. I have a dropper on my marlin that I can put on this bike and shorten the bars to my 730mm preference. And I think I'd be set to ride my (not for bikes) flat ungroomed snowmobile trails in my local forests. Thanks again!

Love your reviews. Will check the bike out further. You should do voice over because you have an amazing, engaging vice

I've looked at their bikes online and the awesome thing is that you can return it within 14 days it's you don't like it. That's amazing. I think all the components on their are made by polygon to keep the costs low and the are made in Indonesia, which is different than most other companies. Thanks for reviewing! You should try framed bikes as well. Their online as well with great prices on their bikes. Keep up the awesome videos!

Great job as always Kev. I am most impressed with the way you pronounce the word “Entity”. This bike is impressive as well.

Polygon sponsors World Cup downhill racers including Tracey Hannah. It’s a legit bike co.

I ordered this bike with the dropper seat post today! Can’t wait to get it and try it out

Polygon is a brand of Insera Sena of Indonesia. They also own the Marin brand nowadays plus they are a big OEM supplier to many shop brands and larger brands. The Calibre Bossnut is a popular budget dual suspension bike in the UK made by Insera Sena. They also do some of the Halford's brand bikes in the UK. I believe they have done bikes for brands like Scott and Kona. If your bike has a made in indonesia sticker its probably Insera Sena as they are the major bike manufacturer in that country. I don't think there are any other major bike manufacturers there.

Hi Kev, as an Indonesian subscriber of yours, I would like to thank you for reviewing one of my country’s most popular brand in your channel. I wished you can review more because we have other brands as well and most high-end full suspension bikes starts at less than 1K. Maybe one day. Cheers

I bought this bike. Video helped me a lot. I am happy with my purchase.

I've heard many comments about the Polygon bikes and I'm impressed to the point that I'm planning to buy one.

Seems like good value. Like you I hadn't heard of the brand before but that's probably not that unusual given the number of bike manufacturers currently in the world. Good viddy, thanx!!! 🇨🇦

Great video I'll definitely check this out. I gotta wait a few more months to ride again it's 0 here now and snow on the trails

I like polygon bikes due to their good looking Frames and the Component that come with bikes. I have the Polygon siskiu D5 and I like it

It looks like a well thought out bike. The parts work with the design, and are not just a conglomeration of high end parts put together to impress everybody on the trail. I like it, but I'm not a full suspension rider. But if I was I'd consider it for sure.

Great review !! I like seeing you get into the mid price bikes ..

Hey kev love your channel ! I just got the polygon d5 a week ago and i must say its decent for the price wish i could have got the d7 but nice review!

Great video, a lot of the people I ride with have gone overseas and they've mentioned this Brand before. They stated that people swear by them as a great bike for the price.

I’ve never heard of the Polygon bike brand but that doesn’t surprise me. As you said it looks like a color scheme from mid-80’s Chevrolet and nice looking. Components look solid and a good value for the cost. Looks like a good buy for anyone in the market for a full suspension mountain bike.

Glad I came across this video... I'm giving serious thought to this bike as my first full suspension MTB.... for the price it seems like a solid choice

What a great review. Answered all the questions that I had. I had just given this bike and the t7 a serious look. I'm in the states in Michigan and I've heard of polygon though. I've never seen any in the wild. One of my favorite Racers Ride For polygon. Sam Reynolds I ended up spending a lot more money on a trek. That is arguably the same component wise except for a RockShox Deluxe rear shock. For $700 more that better be a damn good shock lol. That and you get the Trek. Frame, although my bike is 3 lbs heavier than that polygon

Nice review. I appreciate that you are not a jumper but still give at least some idea about hops.

I own a polygon hard tail and they’re excellent on product/price. The frame is really good and they’re great bikes.

I have the medium 29er version of the D7. Absolutely love it! The Trail Boss tires that are on it are wire bead. I replaced them after a ride or two with WTB Vigilante Tubeless compatible tires. They were a PAIN to get on the rims and setup tubeless. I’ve actually found the D7 to be quite nimble in turns. Not as nimble as my 27.5 Diamondback but that bike has a much shorter wheelbase than the D7 and steeper HT angle. The X-Fusion shock has become one of my favorites. Really enjoyed your review of this bike. I hope the more you ride it, the more you enjoy it!

I watched this video and found the extra space between the tires and frame a cool opportunity to plus size the tires. I like having that opportunity.

Not many reviews on this brand I was looking into the t7 ltd seems to be one of the best bang for the bucks budget full suspension bike and getting a 29er I have 27.5 plus wheel set on my current bike to switch back and forth seems to be legit thanks for the review

Thanks for the honest and transparent review Kev! If anyone has any questions about the bike or Bikes Online, don't hesitate to leave a comment :)

I have been riding this Siskiu d7 L size with 29” wheels since its release in 2019 and i ride it if i want a less aggressive ride along the trail . I only upgraded it with a dropper post and changed the pedals that came with it. And i have no complain whatsoever specially with the price I’ve paid. I’m giving it a thumbs up. Again, i only ride it if i wanna ride a LESS aggressive trail ride as i had my shares of crashes with it. I still ride my enduro bike (from another brand) if i wanna ride a more aggressive ride.

I just bought this bike. Coming from an old Schwinn rocket 88 stage 3. This thing is awesome and rides excellent at the price point. Yes there are better bikes but dollar for dollar its hard to beat

I've been thinking about a full suspension bike , and this Sam Reynolds inspired bike and the calilbre bossnut after buying that Raleigh tokul 1 .I loved it it's down in Tallahassee at a bike shop Its being sent back to me the tokul 1 showed me what bikes are actually capable of doing.it's so awesome you read my mind I swear when it comes to doing videos I've been looking at this bike for a couple of months now now the 2020s are out

Another awesome video, thanks!

I was recently looking at a haro flightline 2 but after seeing this spec list and geometry I’m most likely going to save my money and buy this bike thanks kev

This thing looks great. I think that plush feel would work well for my gf to go on longer XC rides with me. As a casual rider I would definitely like to try this out.

I've just watched this video again as I am saving for a new bike but dont have a lot of money I live in the uk I have £220 saved so far my last bike got stolen and havent been able to ride since I hope whoever stole my old norco hardtail has nothing but bad luck on it I live in the largest town in britain with a population of 77 thousand but you still sometimes come across your bike after it's been stole and sold or cath whoever stole it my norco was bright luminous green but I have never seen it I loved my norco it was old but it was loved I keep getting tempted to go buy a bike under two hundred but in the uk where I live especially I am very limited to my choice enough of my sad story lol I think this polygon bike I think is the one for me thanks kev without your videos lots of us would have went out and bought absolute rubbish so thanks again

if im ever gonna get a new bike this will be it! it suits my wallet and definitely an upgrade from my xc hardtail. thanks for the review, enjoyed it very much! (+this brand is cheaper in my country!)

I do own their RB and it’s a really decent value for the components they put into the complete bike. Definitely a great choice

Wow I'm glad you reviewed that bike because I've been looking at some polygon bikes but at the t7 so if you can maybe review that one as well go job Kevin, also Sam Reynolds rides for team polygon

I have a 2020 Polygon Cascade 4 HT And I love that thing

I'm proudly saying that this polygon bike brand were produced in my Country, Indonesia. Polygon's are very big bicycle company in Indonesia. They have many kind of product with many price range... Also we have " United Bicycle " brand which are Polygon brand heavy competitor. Nice review anyway...

That’s a really good value! I like it a lot 😊

Longer chainstays are good for high speed stability, having a similar role to the slacker head angles everybody is doing these days. And that gap is cool, it is always nice to have space for fatter tires. 2.8 anybody?

The mediums are available with the option of 27.5" or 29" wheels. It's good that the bars come a little wide so they can be cut to the preference of the individual rider. The current version comes with a TransX dropper and a Rockshox Deluxe shock. Still about the best bike you can get for the price point. I typically ride bike that cost more than double what this bike costs, but I had no complaints riding the D7. It climbs like a rocket, and is plush where it should be. I ended up buying one for my wife, who is a more casual rider. Honestly I have a blast hopping on it once in a while and showing her what it can do.

Yes I heard a polygon actually it was in my scope for my next bike. The # 9 has a pretty green color. Ibis it's on my mind right now

Have this exact bike. Been awesome so far. Mine is a 29" wheel. I think the wheel size differs with frame size. I believe you can get either 27.5 or 29.

Seen them on line and wondered if they were any good. Nice to know they are selling a competitively priced bike for the specs. Interested to see some more ride videos on it if you still have it to ride.

My wife and son both ride Polygon bikes. My daughter and I on heavily modded Schwinns. All of us love our trusty steeds.

The drop down menu choices on their site suggest it's a frame for 29, and you can choose 27.5 or 29 wheels if you order a medium.

Hey Kev! Great video as always! I work as a bike designer so thought you might be interested to know that Polygon is actually the "own brand" of the factory that produces a lot of other brand's bikes! Those entity branded parts look like Raleigh branded parts for a reason! They both buy them from someone else (likely Zoom) and put their names on it, looks like they both just picked the same bits! This is a very common practice though so I wouldn't hold it against either brand. Finally, are you aware of SRAM's "trailhead" app/website? You put your forks serial number in, give it your weight and it'll tell you how to set your fork up near perfectly! Can't wait for your next videos!

I just got my 2020 Polygon Siskiu T7 Sram SX Eagle LTD and i fn love it. Great value . Its legit.

I have only ever gotten cheapo bikes from Wal-mart. The best so far has been the Schwinn for around $200. This Polygon looks really, really good without breaking the bank. Gonna have to get one of their $500 models.

I like it... Its nice to see a midrange full suspension.

looks well equipped for the price. color isnt bad..hope you do more indepth riding and videos on this one..

Love that color scheme, sweet ride

Entity is Polygon's in-house brand. Also, even though the WTB tires don't say they're tubeless, you can run them as tubeless tires. I did have experience with them weeping after a time, so add more sealant than you think. Also, x-fusion does make some good stuff. It can take a beating and keep on ticking. There is a bit of advice for the rebound knob on the x-fusion shock, though... It does have clicks going in the other direction, but they're borderline not defined. If you rotate it slowly enough, you can feel the indentation of where the click is supposed to be.

What a deal. If I was in the market for a new dually, I'd be looking that these

I like it. As someone who rides a hardtail, this looks like a great first full sus!

Never heard of Polygon bikes but when you first was showing it, I was thinking this can't be a $150 bike. It looks more like a $1000-1500 dollar bike. And I kinda liked the color scheme.

This bike for what you get seems pretty good. The chainstay issue might have to do with larger sized bikes getting 29 wheels instead of 27.5. also I noticed there is a trail model with longer travel suspension. Cool bike, thanks for the review.

Kev! Looks like you were on the trails at Lost Mountain Park. It is nice to see some local flavor on the 'channel. I live in Cherokee county and work for the Cobb Police Dept. I am very familiar with the West Cobb area. Maybe see you out there at Allatoona Creek sometime. Great Review. I did look at a Siskiu a few years back, but I eventually settled on a Gorilla Gravity Smash.

After this video I loved the huge gap at the rear tire, probably I can go for a 2.6 or 2.8 Xc tire for smooth trailing
