Thanks for sharing! I might be able to find a threaded hole near the rear wheel dropout area to secure the mount.

​​​​​​The bottle cage holder is secured by 2 adjustable rubber bands, (think of Apple Watch's rubber strap), and it can be rotated slightly to the right before folding. So no problems.

Could be paired with Bumm or SON lights which are very small and light:

These locations would be ideal for wheels. Would anyone know which wheel set would fit? I have found wheels with M6 or bigger bearings but nothing with that diameter. Am I missing something?
Also I have tried to improve my approach to folding the bike but I am a bit worried that I always end up scratching the mudguards a bit. Would there be a trick to ensure that the rear mudguard does not touch the ground when folding? I am worried I might be damaging the screw that attaches it to the frame and I am definitely scratching the plastic "bavette" at its end.

Any tips will be greatly appreciated.

Good night!!
Bump! If anyone has an idea it would really help. Happy to create a new thread if this is the way to go :-)

Hi there!

Before I installed the 2+2 rear rack, I used the bike with the Pacific cycles mudguards alone for a while.


Without the rear rack, the rear mudguard sits on the floor when folded, but the connecting plate that touches the floor is reinforced with a thick piece of plastic. Yes it might scratch if I push the bike, but it will not fall apart. I can only carry the bike around but no way to push it.

As for the front, you have to turn the handlebar slightly to the left before folding. You can check the above picture for reference.

There are wheel sets with big wheels which can be installed to roll the bike without rear rack. Sample picture found on the internet:

For me, the best solution to roll the bike folded is not the easy wheels foot like he Ridea that I have on my titanium Birdy but the Riese & MŁller folding rear rack as I have it on my Birdy 3 (unfortunately, this rack cannot be mounted on the titanium Birdy since there are no mounting points for it on the main frame).

I have installed Ezywheels on my white Birdy before, IMHO they make the bike more stable when the rear wheel is tucked in.


However, for pushing around, I found it easier to push with the back wheel alone. Iíve since sold the Ezwheels.

This doesn't work when a rear mudguard is installed.

Thank you for the suggestion. I wasn't sure I could do it as a newbie. Here are a few pictures. Basically the rack has two 4mm diameter to threads, one on either side. I cannot find M4 wheels...

Are you sure itís M4? Brompto and Birdy are M6 and there are lots of wheels available for them. You may try to accommodate one version or another of Easy Wheels for Brompton from, say Litepro. They have bearings so technically if you will secure them they should work. Maybe local Brompton shop/service center can give it a try.

Stainless steel tubes 6mm OD and 4mm ID are common. Basically you cut a piece and make sleeve around M4 bolt for the 6mm wheel to sit on. However the situation is going to be precarious as it may be too easy to bend an M4 bolt under the weight of the bike.

I think you need this. However it's out of stock.

https://www.birdybicycle.com/product...lley-wheel-set

Edit: Found out that mobicbikes.com sells them at $45. You can try ordering from them.

For me, this is not a good solution because when you mount these wheels on the rear folding rack you cannot use rear pannier anymore.

Its much better to mount slim easy wheels for Brompton that are compatible with rear pannier mounting.

Do you mean the remaining space (or length of the rack) becomes too short?




Iím using a 2+2 rack. Could mount the klickfix bag without problems.

He meant panniers, not the rack bag. I also removed spacers from my R&M Birdy Touring but used stock wheels. Have no issues with bags, tried panniers which were also no problem.

I have checked and the diameter is 4mm. The rack is the same as the one for gen 2 birdy I think - the then adventure rack but from the mid 2000's. Here are two pictures of the bike:

Unfolded bike

Folded bike.
I think that M4 bolts would work if short. I really cannot continue to carry it around like I am at the moment.

Birdy RM - Old with broken frame

I have an old Birdy RM and the frame broke at the seat clamp. I've had in sitting in my closet for several years and I want to get rid of it. Generally, is there any market for any of the parts, wheels, seat post, handle bar, crank, etc? I was thinking of tearing it down and sell what I can or just dump the whole works. Anyone have thoughts on this?

This is a Birdy 7


It's not allowing me to post a photo since I'm a brand new member or I don't know how to use this forum. I have not been in a forum in a long time.

Thank you.

It depends of the type of Birdy (1, 2, 3, monocoque or not...) and of its transmission (derailleur or IGH, number of speed, type of IGH...).

If sites like eBay are out of question maybe you can show pictures to local bike shops/service shops, maybe they would be willing to take it for parts.

I found the owners manual. It is a Birdy 7 with a Shimano STX-RC derailleur. 7 speed.

Ebay is not out of the question. I just sold a bunch of tools...their fees are so high, plus they tie shipping into them. I will check the shops and see if there is any interest. Thank you

Difference between Comfort and Sport stem?

I'm looking to buy a second hand Birdy Gen 3. I've test ridden one with a comfort stem and liked it. I've seen a second hand one with a sport stem. I know the difference in the number of degrees but could someone tell me how much further forward the sport stem is in cm/inches? I know this will be different depending on height of stem but any indication would be really helpful. Thanks.

Comfort stem is 10 degrees while sport is 21. I believe it would be possible for you to calculate the distance based on stem hight you would use.
