I think converting to a 1x, upgrading suspension and brakes would do this bike wonders. But at that point, buying up to the next bike level might be a better option.
I got this bike after years of 26"-hardtail-riding. It is no relevation but at least a huge increase of performance to me. Having, lockout, 18 gears and a relatively light bike feels still like driving an XC-hardtail uphill - which is nice if you ride local trails. First I installed a dropper post and I am thinking of getting better brakes (the small rotors feel like hydraulic rim brakes - which is not so bad).
I have the same bike, just bought it used and perfect condition for $800. After market goodies too, I've mountain biked before for fun, I race dirrbikes and ride dirrbikes very frequently.. that being said, I love this bike I'm 155lbs and it's been very capable, I'll probably upgrade the shocks and handlebars and drive train but no complaints.
I used to have a 29er motobecane- was entry level and all stock but a few parts really loved it on beginner trails - as I am by no means anything but a novice at the moment- well I lost the bike a few years ago and I decided to get a new bike - was going to get another one when I came across this bike although it is now a 2024 version- I upgraded the front fork to an air ride - I’d suggest a tapered rock shx Judy silver in a tapered - it will smooth a lot on this bike- get a budget friendly dual chamber air shock for rear and enjoy this bike it’s a bike that can do way more and it’s proven itself with a good rider. That’s not me at moment I’m starting over so to speak but it’s a good bike for folks that will stick with you for a while on your mountain bike journey
I have this bike. I had no idea. It was a big dinner bike. It has helped me with a lot. I think that the traction the tires good could definitely be improved. But as far as a bicycle goes, it has about the best traction. I've ever seen on ice snow, mud, Sand seemed to be the only terrain that the bike hadn't issue on, when im in the city I roll over large curbs with little to no effort, The bike is very durable. I have ridden it a few times when I was drunk. I got into a few crashes and the bike came away with barely a scratch. My only complaint about this bike is hardly complaint. But it's not very fast and it seems hard to maintain speed with it. I'm not sure if that's common with mountain decks. As in the past, all the bikes I've ridden were very good at coasting. But this one is not very good at coasting on flat roads.
I have not had a chance to ride very much but from the little time I have on it I can't believe how light and easy it is to go up a grade with it. Looking forward to trying beginner bike trails with it.
I certainly am pushing my luck with my Giant Revel 29er hardtail. I'm 5'10" and feel that a 27.5" M would fit me better plus I'm ready for full suspension. So ready so stoked.
This video helps. I own one of these. For someone who converted from hardtail to full suspension, I really enjoys riding this bike for the last 5 months. Right now I am doing research for the suitable upgrade for the D5. If you could layout a video that would give a recommendation of what brand or parts (boost, non boost etc) should a rider go for if he or she decided to upgrade their D5. Thanks
I agree. Straight from the factory, you have a capable bike that could handle a lot more than the D5. Especially at the price point of the D7, it’s hard to argue that the D5 is a better value. HOWEVER, a lot of the components would still need to be upgraded to make a fully capable bike, which at that point, why pay the extra $700 for the D7 just to upgrade them? It all comes down to what your plans are with the bike.
@@TheShredShedMTB so should I get the d7 if I don’t upgrade at all? If I got the d5 I would most likely upgrade it that would add up to the price of the d7.
If you’re looking to upgrade right from the start to have a more capable route, that’s probably the route i would go. It really only makes sense to upgrade the D5 if you do it over a longer period of time, or as parts break
Will upgrading fork and shock make it ride smoother or just more tricks I'm interested in smoothest ride no tricks or jumps old man smooth drive which has to go in trail in order to get to next town
What I did I bought a cheaper bike but still a quality bike and as I got better I just upgraded it to match my riding skills as I get better and I have not had to buy a new bike since but I have been looking into a full suspension instead of my hard tail because as of now the hard tail is holding me back
I am looking to buy a new one of these today. It’s 2021 so clearance and at £575 I thought this wasn’t too bad for a bike of This spec, I am open to being told otherwise but I have been riding a Trek 26in hard tail for the past 15 years so looking to dip my toe in full suspension but not go all in
curious if you went this route? personally, I think this bike is more for beginners and think you might outgrow the specs pretty quickly if you've been riding for a while. that being said- you could upgrade every component on this bike too!
@@TheShredShedMTB as I have never had a full suspension bike before I took a chance on it at the price it was. I have only managed a couple of decent rides so far but it feels pretty good. Forks are my one downside, they will likely be upgraded
Hey man I am brand new to mountain biking, and I have been looking for good mountain bikes for the price and I was thinking about the polygon D5. I have a trek fx2 road bike with no suspension and if I did a jump with it when I land it would make tons of noise. And I was wondering if this polygon bike would do the same?
If you’re already jumping, I would say that your abilities are probably beyond an entry level bike. Personally, I would probably save up a bit more and get a bit more quality in the bike. This isn’t a bad bike at all, but it’s a very entry level bike. I personally wouldn’t do much jumping with this.
I have this bike and I love it ,I'm about to upgrade the front fork , I have a Rockshox recon but i need to know what bearing set i need. if anyone knows please let me know .I'm sure it's just a bearing kit but i'm just not sure.
Thanks for the video, you convinced me to stick with my 1996 hoo koo e koo.. a quality American steel hardtail really is gonna be a better bike than an entry level China bike
The parts are made of a lower quality, cheaper material. They are also less refine. And because they are inferior to modern components, demand is lower which makes the price cheaper.
Question. Does anybody know if the 2021 D5, D6 & D7 frames are the same exact product besides their paint jobs? I noticed that the upper linkage on the D5 seems a little bit different but everything else looks the same to my eyes. Any help would be greatly appreciated as I want to grab one of these and would almost rather get a D5 and do some upgrades. BUT at the same time a D7 is looking pretty sweet so it's a tough call without knowing what the real difference is when it comes down to the frame and linkage parts on their own.
I think they may be slightly different, and I only say that based on looking at the rear dropouts. The d5 is quick release while the d6 looks to be through axle
@@TheShredShedMTB Thanks man! I honestly don't know how I didn't notice the D5 had quick release. The more I look at these 3 D models I think the D7 is the clear choice if one can afford it.
Have the same bike and I’ve already begun to upgrade, the stock suspension on this bike is heavy and awful, I upgraded the front forks to rockshox judys and also upgraded the rear shock to a rockshox monarch. Both make the bike a lot more capable. Also I would recommend putting a set of maxis tires on it.
It made the bike very capable, I rode it hard for over a year and never let me down… I recently just bought a new specialized stunt jumper carbon pro and the polygon was just as fun.
Feel it meaning, like feel that it’s a lower end shock, if so, yes. It’s pretty noticeable that it doesn’t do a whole lot. But... it’s more cushion than a hard tail lol
I just bought a giant hardtail hoping to get into mountain bike my dad rode a mongoose rockadile till it seized he bought himself a nishiki pueblo, and the trails aren’t getting any easier should I save up and by him this?

This bike just isn’t designed for that. It has budget friendly (lower end) components built around an XC frame. Even with better components like brakes, suspension and wheels, the geometry just isn’t designed for rowdy descending.
@@TheShredShedMTB i feel kind of limited with the bike since i want to hit harder trials but the bikes not meant for the harder trials, but i can’t really be complaining since that was all i could afford lol
