Those 2 wheeled things don't seem to be actual racks, but an accessory to let you wheel the bike around as mentioned and nothing more. I can see no way to use them to carry luggage or other items.

The four wheeled racks are just that. They serve a dual purpose, carrying cargo and letting you wheel the bike while folded. Not only do they act as a kickstand, you can also complete the fold without hoisting the bike.

Hello, can someone inform me whether the OLD for a cassette/derailleur Birdy is 130mm or 135mm?

Thanks!

marxmini

130mm in my classic but i don't know for the monocoque version.

jur

My Birdy with monocoque frame had 135mm OLD. But that was 7 years ago and they might have changed.

leoho5

Thanks for your replies marxmini & jur. I have a Monocoque 135mm with Nexus hub but was wondering if the Monocoques with cassettes are 130mm. Anyone know if Monocoques only come in 135mm?

Thanks

bhkyte

I believe they are all the same frame.

leoho5

Oops, I now see that your Monocoque was a cassette/derailleur Birdy so I think it's clear that it only comes in 135mm. Thanks for the help. Thanks also bhkyte.

bhkyte

It will still never be as good as a Brompton!! Untill it changes it's name to Brompton. Lol

I have heard it now folds a tad smaller? Any comparison photos?

bike.gang.uk

Ha, don't say that in Birdy thread

It is said to be 15% smaller, can easily fit in new reach luggage without removing the handlebar.

Default all disk brakes, hidden headset, build in PC chain tensioner, bigger cockpit ...

jmaher

Hard to believe all the changes. It all sounds very positive. Has anyone ridden one?

bhkyte

I am using the chain tensioner and a short cage mech on 2 of my bikes. Even at the high price to buy separately I would have it equipped another way. I try the LBS as they may have the new version.

Sir Coastalot

This evening on the way home I stopped by my dealer, who just a few days ago received the two new monocoque Birdies for the Japan market: "Sport Disc" and "Standard Disc". All in all, there aren't too many differences between them. The Sport Disc model has a 10-speed cassette (11~34T), while the Standard gets a 9 speed (11~32T). Both have mechanical disc brakes. Also, the Sport gets a sporty Sella Italia X1, while the Standard has a comfort saddle. Both the Sport and Standard have an offset stem that can be flipped between 21 degrees and 10 degrees.

Although the folded up size of the new monocoque is supposed to be 15% smaller, it's not readily apparent side by side with the old model. Even the dealer wasn't sure if it's any smaller.

I took the Standard for a spin around the block, and the lower BB height is noticeable. It's now 279mm vs 291mm of the old monocoque. For comparison, the BB height of the Classic is 290mm. The top-tube is also longer at 591.6mm compared to 586mm of the old monocoque (588mm in the Classic). I had no problem standing up on the pedals.

The first pic shows the Standard side-by-side with my Reach. Unfortunately, my stupid iPhone was in "square" mode so it's horizontally truncated, but on the left side you can just make out the right-hand grip of the Birdy is the same distance from the seat as the tops of my Reach's dropbar, although a few centimeters higher.

The second pic shows the Sport, which a chap purchased just as I arrived. He was kind enough to offer me a test ride, but I declined, afraid to put any scratches on it. The glossy black paint looks stunning.

marxmini

i want to have one please. :-)

Hi, my first time in this thread and read back to mid 2014 so not sure if you guys know of these.
I was out perusing bikes today in Bangkok and saw crazy pimped out Birdies? called Color Plus.
They had color shift paint, carbon rims, billet shocks and even billet kickstands.
Over $5000 here in Thailand.

Colorplus has made some very beautiful parts for Birdies, here is a cabon black version of new birdy, with full set of colorplus mod parts...

Hmmmm, so they are now sold as Birdy in Japan now, rather than BD-1? Still imported by Mizutani, or possibly brought in direct by the dealer?

Clownbike

Have done some upgrading/accessorizing on the BD-1. Added fenders, as I had a set on hand and like to use them anyway.

The silver classic I have had the adjustable handlepost with an ahead stem, so swapped the handleposts between the two bikes. All went swimmingly until the fold, the old style handlepost impacts the new frame, so reverted back to stock. Picked up one of those handlebar extenders and it made things much better. While at it added a carbon handlebar, carbon brake levers, and Biocork grips. Now has a very comfortable ride.

After swapping the handleposts, the shifter cable was too short and needed replacement. Had an SRAM X-9 derailleur and trigger shifter on hand so installed them along with an XTR Ti 9 speed cassette.

The ColorPlus pneumatic suspension works very well. No po-going, even standing on the pedals. And I like the wheeled rack, makes it easy to park and maneuver around.

Guess that's enough mucking about for now. The bike rides nice and there's not much left to do, other than a carbon crank set.

Sir Coastalot

From what I've read, it was renamed BD-1 for the Japan market a few years back because Suzuki owned the Birdy trademark (and used it for one of its 50cc scooters). Somehow, that issue was resolved between Pacific and Suzuki, so from this year on it will be sold under the Birdy name (and also directly by Pacific, not through Mizutani).

That said, looks like Europe will be getting monocoque models with more options than Japan (IGH, etc).

Hi everyone, just wanted to note that Urban Bike Fitters in Fremont, CA is now an authorized Birdy dealer. I test rode one today. Pretty sweet ride. I also tested a Nanoo. It wasn't for me, but it's a neat bike.

David Sands

I'm interested in buying a Birdy folding bike. I live in London but can travel. Does anyone know of a good dealership in London, or anywhere else that is good in the UK?
Thanks.

Hi I just gotten myself a 9 speed birdy and must say that it's really nice ride.
But I notice that when at lowest gear, the rear derailleur seems to rub against the tire.
Is there a way to fix this? It's basically stock configuration with 11-34T cassette and a 56T chain ring.
I am wondering if it's because of the long cage derailleur?

bhkyte

birdie is a tad flawed in design.
solutions i know of are fit narrow tyres, change to ihg .
else change to a short cage rear mech which also improves ground clearence. then the cage doesnt reach down to the tyre. if you do this you may want to fit a chain tensior,else chain falls off in folding, 70 pounds please. but then you can get rid of the chain catcher that gets stuck inthe rear cogs and breaks transmission parts as it locks up. it worth shelling out on the new chain tensior in the long run.

Winfried

This one from Pacific Cycles:


Cheaper alternative from Ridea:

I have got both set ups across my birdies. I payed a silly amount of money for a ccn bolt that replaces the chain catcher like the secound one. It does not work really well as regards stopping the chain coming off in the fold but its ok on a spare bike. At least it does not jam the rear cogs up by bending in to them.
For regular folding I prefer the new birdie chain catcher. Its standard issue on new birdies. I dont know if they are also fitting a shorter cage rear mech?

As you don't need a long low cage with it fitted.
