First Look: All-New Bird Aeris 9

Aug 3, 2022

Readers outside of the UK may not be familiar with Bird bikes, and that's a shame because the British brand has earned a reputation for offering solid value and an innovative spin on the direct-sales approach. They ship internationally and are looking to set up demo partners outside the UK.

They started out in 2013 as a 27.5"-wheel-only bike company, but soon spread their wings to include bigger wheels. The Aeris was their first full-suspension bike in 2014, and now they're releasing the sixth bike to bear that name. Confusingly, it's called the Aeris 9, where the number relates to the 29" wheel size, not the design iteration.

Bird Aeris 9 Details
• Travel: 160 mm or 180 mm rear, 160-180 mm front
• Wheel size: 29"
• Adjustable geometry
• Customisable spec
• Internal or external cable routing
• Sizes: M, M/L, L, XL
• Reach: 457, 486, 515, 544 mm
• MSRP: From £1430 (frameset) or £2870 (full build)
www.bird.bike
Bird describe it simply as "an all-mountain machine with a bias towards gravity racing." That might be putting it mildly, though, because the bike pumps out 160 mm of rear wheel travel in standard form but can develop 180 mm with an optional linkage, can accommodate 160-180 mm forks and boasts adjustable geometry that can get pretty wild.

Cables can be run inside or outside the tubes, but alas, not through the headset.

Frame Details

The Aeris 9 frame may look similar to Bird's 150mm-travel AM9, but it's an all-new aluminum tube set designed to cope with the stresses of 180 mm forks. Among other differences, the Aeris 9 takes advantage of SRAM's Universal Derailleur Hanger.

One feature that's easy to miss is a flip chip in the chainstay (Horst) pivot which simultaneously changes the chainstay length, BB height and frame angles.

The top-tube mounted shock can fit a large bottle even with a piggyback reservoir. An optional shock link increases the travel from 160 mm to 180 mm while using the same 65 mm stroke shock. There's little information about the kinematics at this point, but it's offered with both coil and air shocks.

Geometry

Bird have gone big on sizing. With sizes going from Medium to XL, the Aeris 9 is aimed at riders on the taller part of the spectrum; keep in mind that Bird also offer 27.5"-wheeled bikes with Small sizes included. The Medium is recommended for riders around 168 cm (5'6"), while the XL is for those around the 194 cm (6'4") mark. With a 544 mm reach, the XL size might be best suited to those pushing two meters.

The above chart is for the bike with the short chainstay flip-chip setting and a 160 mm fork. In the alternate flip-chip setting, the chainstay length is 6 mm longer, the BB is 7 mm lower and the frame angles are 0.5-degrees slacker. Fitting a 180 mm fork will take about a further 0.8-degrees off the angles. In the short chainstay setting, the head angle goes from 64 degrees with a 160 mm fork to 63.2-degrees with 180 mm, but this could go to 62.7-degrees with the lower flip-chip setting. Simple, right?

In addition to all that complexity, the effective seat angle changes by size, from 77° in the Medium to 78.5° in the XL - that's in the steepest configuration of fork travel and chainstay setting.

Specs and Pricing

Bird take advantage of their direct-sales model to offer complete customisation of the parts and setup using their online configurator. Supply problems notwithstanding, you have a choice of almost all the components. The idea is you can get the bike you want from day one, without wasting time and money swapping parts to your tastes.

You can pick parts from RockShox, Fox, SRAM, Shimano, RaceFace, MRP, Hope, DT Swiss and Formula. You get a choice of Maxxis tires too.

bigquotesWant an XT shifter with your Deore drivetrain? No problem. Need to match the colors of your headset and hubs? We’ve got you covered. Need your bars cut to 764.2mm? Sure - we’ll do that for you.Bird

By today's standards, the pricing is relatively cheep ... I mean cheap. The Aeris 9 frameset starts at £1,430 and the entry-level build starts at £2,870. Bird recommends aiming a little higher up the pecking order, though, suggesting a build with a SRAM GX Eagle drivetrain, SRAM G2R Brakes, RockShox Lyrik Ultimate fork and Super Deluxe Ultimate Coil shock, Bird Factory wheels, Maxxis Assegai tires and Bird & RaceFace finishing kit - for around £3,875.

Bikes are available to order internationally now at www.bird.bike. Demos can be arranged in the UK at Bike Bothy’s stores in Pitfichie and Laggan, Glencoe Mountain and Bird's showroom in Eversley, Hampshire.

 My Aether 9c has been acceptable, but I'm tempted to change it for something some long legged, and this Aeris 9 looks a great option. Bird have proven helpful on warranty, with turnaround times about as good as you could hope for. Their dispatch arrangements were less good, where they twice shipped things to the wrong address.

 @BirdBikes: That's right in line with my current alloy enduro bike. I'm considering selling it because 29-inch wheels might work better for me in the chunk. My locale terrain in Washington State is very much like your Forest of Dean trails. Amid a very crowded field of enduro bikes on the market, the Aeris stands out on value and component choices.
  • 2 0
 @NWBasser: 34.8 lbs for my AM9 with DD tires, lyrics, SD ultimate air shock, hope alloy wheelset, guide re brakes including DH clipless pedals. Not that bike weight is any issue to me (I weigh 210lbs so barely notice a few grams here or there on a bike).

If only it were that simple! As Kimbers says, there are plenty of adults living with the consequences of something they couldn't vote for/against. The winning margin was very close and many people didn't/couldn't vote meaning there's hardly a majority of the UK that are pro Brexit. Add in the fact that we were simply asked to vote to either stay or leave the EU, there was nothing beyond that. We could have had a "soft" Brexit and stayed broadly aligned to the EU but the electorate were never consulted on the finer details.

 aren't they just! working in the industry for 12 years and have had all sorts of exotica, but the AM9 is BY FAR the best riding bike I've owned. its not even funny how much better it is in pure performance terms and when you take the cost side in it makes you wonder about the rest of the industry.

 For any y'all outside the uk worried about "brexit taxes" remember that in UK sales tax is included in consumer prices as standard, is 20%, and is not chargeable if the goods are going out of the UK. You can also ask the exporter for a price "DDP" where they take care of all the duties to remove any doubts.

 I love my AM9 and the way Bird does business. There needs to be more bike brand out there like them. I’ve had mine for 3 and half years, this new Aeris 9 is the first bike in that time I’ve seen that I would consider replacing mine with, but it’s so damn good, I’ll hold off for now. Keep up the fantastic work Bird.
  • 2 0
 Similar story here. Had my AM9 for over 4 years and I still love riding it so would certainly consider an Aeris 9 as a replacement. I think I’ll book a demo ride on one at Laggan to see if it feels different enough to warrant the change.

 @thingswelike: i dont know if its encouraging or not, but its worth noting that the am9 frame is one of the lighest full sus aluminium frames in this category. youre saving nearly 1kg by not having a commencal or transition.

also, i couldnt break mine, i went and cased the drop at the bottom of stile cop about 5 times just before my ankles had had enough (sorry bird) and the frame took it fine. they told me theyve never had a broken frame, I'm not sure i believe that, but i dont doubt their statistics are really good.

  • 1 0
 @thingswelike: i ruined my am9 with the coil shock... i got a DHX RC4 and converted it to metric length (if you get the 241x76 its pretty straight forward to do) but the tune was all wrong. not making that mistake again!

by mistake i mean shock with the wrong tune, not coil shock, or trying new things.

 @GumptionZA: Mine is the Super Deluxe Ultimate, but I had to swap the nice red spring for a 275lb nukeproof one to get more travel. I'm probably better off with an air shock in future.
Only problem I have is on continuous rough hits when not too steep, it seems to get slowed down. Thought the lighter tune would help, but it hasn't. More playing needed. Love it on the big stuff though and as I said on the trialsy stuff.

  • 1 0
 Height suggestions are just that; suggestions. I think Bird embraces the long reach thing more than other companies. I doubt this is a typo. Meanwhile you have a company like YT suggesting a reach of 487 for somebody up to 6'4" on their enduro bike, which many would say is way too short for that height. Just suggestions, pick what you prefer and slide your saddle to adjust for TTL.
  • 1 0
 @Gristle: Totally. And I am sure there are some very tall folks who will appreciate their size XL. But man, that has to be a very small demographic!

I'd have to think someone would reasonably need to be at least 6'6" to fit optimally on a 544 reach bike. That means XL's would be useful to roughly 0.04% of the population, or 1 out of every 2,500 men.
  • 1 1
 @KJP1230: I'm 5'10" and the 495mm reach on my bike is perfect for me!
  • 2 0
 @KJP1230: As an am9 XL owner 6'3'' with rather longer legs and shorter upper body, I can asure you, long reach is just fine. If it fits your riding preferences. These bikes don't flip around playfully but damn they hold the line you aim for ;-
Addionally the stack of the birds is quite low, so as a tall rider you will run some spacers, which shortens the reach. Me I go for a 40mm riser bar and even 50mm stem at 522mm reach and don't feel too streched at all.
But I also own a bird forge and set it up with dorpbars for gravel. As said, preference but definitely not extreme.
The wheelbase of the new aeris 9 though...whoohoo. Hold fast and enjoy the ride!
  • 1 0
 I'm 6'6" on 535mm of reach and a 1350WB and it's fine but I have to run a 50mm stem and the bike is quite long - proportional but long. 544mm of reach means I could get back to a 35, which would be nice. A bike with 544 reach and 1330 WB would be a nice balance for me.
  • 2 0
 @bishopsmike: Holy smokes! I am fully 4" taller (and with very long arms) and my 485mm reach bike feels borderline cumbersome - and that is for a full on enduro rig. Just goes to show - different people can have radically different preferences in terms of feel.

 I'm on an old (by today's standards!) XL Bird Aeris 145 with a reach of 528mm, I'm 6'5" and run a 50mm stem. The 544mm reach could fit me fine as I could reduce my stem length by the same 16mm increase in reach. It's definitely a long bike but it gives you options to downsize. I could ride an ML if I wanted something playful.

 I've had my Bird AM 9 for a couple of years now and I love it. The only thing is that I think the large is a little on the long side for my 185cm height, so keep that in mind. It's a lot of bike for the money these days!
  • 1 0
 I'm about the same height. Maybe a M/L is the way to go if I order one. How are the climbing habits of your bike?
  • 2 0
 @NWBasser: I don't really have too much to compare to. I had a first-gen Cotic Rocket Max beforehand so that's my main comparison and I would say it's good compared to that. Not the lightest bike, but its a bike that's not really about the climbing performance and it gets you to where you want to go.
I think I would go for an M/L if I were ordering it now as I'm more of an all-mountain rider than an all-out Enduro rider, but if your focus is going downhill fast and less on agility then you probably won't be disappointed with the L.

 I was so close getting an Aether 7 frame but after import duty, taxes and shipping it would end up costing the same as an alu Santa Cruz. Went for Privateer instead which is currently the best deal by far if you don't mind a bit of extra weight. That said I've been following Bird from the beginning and I really like their approach. My only complaint is that their latest frames don't cater for shorter riders.

 These guys, Revel, We are One, these are the companies ill be buying from in the future. Will NEVER own a Pivot, Santa Cruz or Yeti. Leave those brands to the golfers.

 Just imagine combining WA1 wheels with a Bird then.
I did that with my AM9 and the thing just go. A stupid strong frame with a superb geo and some strong lightish enduro carbon hoops. Combining DD/ebike tires, durable alloy parts that AM9 alloy frame in size L and the thing ends up at 32.6lb/14.8kg.

 @BirdBikes: what made you choose the boost standard over the superboost for such a serious bike, especially one that can be ridden as a full 29er? More and more brands go 157mm at the bike even on their enduros with less travel than the new Aeris. Smile
  • 7 0
 @hitarpotar: superboost for us is an unnecessary step. Realistically no-one is folding over wheels anymore so they don't need to become laterally stronger, and there's plenty of downsides to the wider rear end including heel rub, placing your mech further into harm's way, and being forced onto a wider q factor.

If we suddenly found people taco-ing wheels we'd consider it but until that happens were sticking with 148.

  • 7 1
 @lurch710: but functional. The bike itself is not the most streamlined bike out there, but is easy to work on in most cases. I prefer a functional bike that's easy to service. Internal routing does not fall in that category. It can die a slow, painful death for all I care.
  • 2 0
 @Primoz: yes it was functional but the cables were running too much on the sides if u know what i mean. visually it wasnt that pleasant and the cables may get rubbed/tangled during crashes. fyi, all my bikes are externally routed
  • 2 0
 @lurch710: that's something we had on earlier models but we updated that routing for our gen 3 models some while back. If you externally route the Aeris 9 you get that same clean and straight gen 3 routing on this one. It gives the straightest available run for hoses and outers. The internal run is almost as good but not quite so clean but still without harsh turns or awkward spots.
  • 1 0
 @lurch710: In the 4 years of running an AM9 I've only had a small nick on the Reverb hose near the BB area from a rock or something. The cables/hoses never tangled up in anything.

As a counter argument, running the cables and hoses more to the side of the downtube makes it easier to clamp the bike in a roof/tow-hitch rack directly onto the frame, not through the cables and hoses, which gives a sturdier fixation point.

 Aether 7 is ridiculously similar to my 2018 aluminum altitude in the details. Same HA, CS, even shock size. Major difference is 20mm less travel and a significantly different outlook on sizing. The FC:RC ratio in L and XL is wild.

 Looks great. Its nice to see a proper bike made of metal, sensible geometry, well specced, great price and no stupid Mullet set up. A proper bike for riders who appreciate mountain biking as it should be and not fads! Shame there isn't more of this around.

@threehats He's also droned on about how 29 was a conspiracy. Despite the fact that according to Gary Fisher, mountain bikes were originally designed for 29.
