My day job is in travel and January is always manic, so I decided to book 2 days off and ride bikes instead. Rather than ride mine, I thought I’d give the new Bird Aeris models a go and pop some first impressions up to help people that may be looking for a new bike.
Bird have redesigned their full suspension Aeris and now have 2 more curvy models based around metric shocks and boost spacing; the One20 and the One45.
I gave the guys at Bird a shout and before I knew it, I was picking up the new Aeris One20, Birds newly designed 130/120mm trail bike and was en-route to Swinley Forest, which I figured would make an excellent testing ground for a bike with this amount of travel. It was a damn cold but sunny day, sitting around minus one, so the ground was crisp with some damp spots on the more loamy sections. A perfect day to spend outside, rather than confined to an office. If you’ve not been to Swinley Forest yet, I’d highly recommend it for it’s all weather friendly trails and the laughs you’ll have at the hub with the team there.
The model I tested was a large, which at 6’1”, was spot on. Kitted out with 130mm RockShox Pikes, their new metric Deluxe RT3 rear shock, SRAM GX 11 speed drive and Guide RS brakes and DT Swiss E1900 wheels with Maxxis Minion DHF front, High Roller 2 rear both running low pressures of around 18psi. Keeping the muck away is the ever reliable Mudhugger shorty. It was a setup similar to my current bike, except the new models now sport bottle cage mounts, making them super enduro!
My initial thought was that the weight was very low for an aluminium bike. I didn’t weigh it with scales, but was impressed with both that and the sleek new curves and frame design in general. Heading through the high sided berms of the blue runs at Swinley, immediately I could feel the bike gripping in the cold, icy conditions too. At times, it felt like I could get practically horizontal and still go lower.
The bike is also long. Very long, with a top tube of 655mm on the large, offering a wheelbase of 1220mm! However, thanks to a steep seat tube, during the climbs it also felt compact which worked in my favour… it’s hard to explain, but it just works. You can check out the full measurements below:
What impressed me most however, is when I got to the red sections and off piste areas. I figured I’d hit a few drops that I’d not usually attempt on a short travel bike, but it ate them up with ease. It’s a bike that definitely punches above its weight in terms of gravity riding; I didn’t feel like I had 120mm travel, that’s for sure. As somebody that can’t jump for shit, it also inspires confidence and after a few attempts, I was clearing the table on Babymaker like a (not so) pro.
The metric shock may have something to do with this. It felt a lot smoother and more progressive than my Monarch RT3 Debonair. Technical data isn’t my strong point, but I’m sure the Bird guys would be happy to explain ramp up and linear feels! A few close ups for you:
Like a chainsaw or a scalpel, in the hands of the right person, this is one seriously fun piece of kit and I reckon it’s going to be a sure-fire hit. It’s a bike that is made for the likes of Swinley Forest, but I’m sure people with more talent than me will slay the black runs of Bike Park Wales on one of these! It’s already got a race winning pedigree too; Chris Doney rode one to victory in the Southern Enduro last year.
Its main competition in terms of UK brands will be the Whyte T-130 and the Cotic Flare, neither of which I’ve had the chance to try yet… I’ll look into that soon.
If you’re looking for a really fun trail bike at a great price, the Aeris One20 should definitely be on your demo list. There’s a huge amount of sizing, including a ‘medium long’, as well as a fully custom bike builder, so there will be one to suit you for sure. Prices start from an incredible £1681 and you can choose from Atomic Blue, Candy Orange or Tungsten Grey.

To sum it up, at the end of the day when dropping it off at Bird HQ, my legs were aching from pushing myself and climbing faster than ever before and I had a big smile from an epic day out on a stunning bike. It feels superb going up and descending and has a huge grin factor. I do think I’m personally more suited to a larger travel bike, having had a 160/140 Aeris for a while now, but the One20 is a bike that absolutely has its place in the market as a short travel trail destroyer.
However, although sad to give the One20 back, I was handed a One45 and had a date with the Surrey Hills the following day… you can read that review here.
Big thanks to the guys at Bird HQ for the demo bike and to Swinley Forest (and the ever awesome hubdudes) for the fantastic test ground.
Peace out for now,
