Good finding, I adjusted it to this angle so that some certain body parts will not feel uncomfortable. 😂

I‘m interested in that as well.
I left it open without thinking about it.
How is it on Birdys delivered without a lowrider?

Thank you!
This thread, or to be more precise, the mention of the H&H adapter made me reconsider a Birdy. So, in a way, this is my Birdy-home ;-)

The pump is a Crank Brothers Stirling mini pump that i quite like and that comes with a holder. I secured that holder to the rack with zip ties. As soon as i‘m allowed i‘ll post a picture.

Went for a ride today and noticed a noise in the front when I was increasing the speed. I didn’t bring the bike to my mechanic yet so I don’t know what can it be, brakes that need adjustment or hub?

There is probably a hole at the other end too, but I haven't checked. Dirt can get in and slowly accumulate too. For peace of mind and better looks you could use a short bolt and perhaps a small rubber o-ring to keep it sealed and keep the bolt from shaking loose.

I sometimes get a little rubbing noise from the front disk brake in hard turns, the fork flexes enough to cause rubbing. This is harmless. Don't know if it's the same noise you have...

I checked several adaptors and am thinking on buying Trigo which looks better to my eye. Since I have comfort stem lack of angle shouldn’t be a problem.

I’m about 100kgs and my R&M Birdy Touring came with red rear elastomer which seems to be a little too soft. Trying to order hard one but they don’t seem to be available all that wide. Found this one but its grey and it reads hard. As far as I know hard ones are green. Is there a difference for elastomers for Birdy 1, 2 or 3 or they fit all models?

I don't remember, but I think I got my green elastomer from here: https://www.mobicbikes.com/collectio...mer-green-hard
It says it fits all Birdy models.

They don’t ship intentional. Ordered from Migjty Velo. Thanks.

So I‘ll rephrase my reply since the original text was lost:
Please use Loctite with whatever adapter you buy. Both the H&H adapter and the Brompton luggage block came with Loctite blue.

Thanks, I always do, on all bolts that are not supposed to be unscrewed.

On Birdy without low rider, there is a bolt that close the threaded hole.

Did the same, put short ones in. There is a hole from the inside too, added washers to make sure bolts don’t touch each other inside the fork.

I recently changed the suspensions with harder ones from Ridea.

The adapters have tiny set screws that are used to lock in the top (tension) bolts by screwing them down on the threads of the tension bolts. I think that even if the set screws were to back out, that having used them, the threads of the tension bolts would be damaged and will resist being unscrewed. They also supply a loctite type liquid.

judging from the price these are made from solid chunk of gold. I looked at different options with sane prices for front suspension but they all are stiffer than stock and I think stock is fine for me for now. If not there are options to change the spring for a stiffer one.

I have Matumura Kohki Scrowave suspension on my Brompton and am very happy with it. Apparently there was a model available for Birdy but I’m not sure if it’s available any longer.

jackyharuhiko has a Pacific Cycle Birdy, most Pacific Cycle Birdy are factory equipped with the 10.5 turn softer front spring while Riese & Müller Birdy are factory equipped with the harder 8.5 turn spring.

For me, the original front suspension with the 8.5 turn spring is perfect ( I am around 80kg), the softer 10.5 that was factory mounted on my Ti Birdy was too soft especially with a loaded Brompton front bag.

I tried the Multi-S G5+ suspension set (that seems very good with a front spring+hydraulic damper and sophisticated rear multi-rubber system) and it was bad.

The rear is ultra hard, there is almost no suspension. I couldn't compress it by pushing on it, then I put it in a vice and even so, the max compression I could obtain is about 5mm.

The front is also harder with a shorter spring that results in a shorter travel than the original and the top ring for the hook has a rectangular groove that doesn't fit with the shape of the frame hook (which is designed to hook a spring = a round object) with as consequence a continuous rattling noise coming from the front suspension.

I also tried the Ridea PU 100 hard rear suspension and it works slightly better than the original but the M3 very long mounting bold was broken several times, I eventually glued the several parts of this PU block instead.

thank you very much Jipe!
This is the information about my front suspension and the rear suspension - a newer version released in early 2021.

Well, M6x80mm were too long and didn’t fit, original bolt is 78mm (wtf?). Didn’t want to use washers and ordered new ones 70mm.

Found this test comparing SON, SP and Shimano dyno hubs. Does it correspond to SP hub model used in R&M Birdy 3?

SP hub seems to be least efficient with highest drag.

I just checked B&M IQ-XS model which is 70lux (or 80lux acc to b&m site) like supernova E3 Pure and has almost identical dimensions, 50 x 40 mm vs 49 x 41 mm on Supernova E3 Pure 3. Difference is IQ-XS has a built in switch and light sensor which automatically switches it on/off, two side light strips for side visibility, aluminum casing. Also back light connection, so B&M rear light can be installed on the rack. Dis you consider this option before? I’m pretty sure IQ-XS will also have excellent optics and wide beam. Not sure how reliable it is though as there were few reviews on the Amazon saying it died after less than a year.

Yes, I noticed that one. I will consider it if/when the supernova fails. The supernova also works fine with the B&M tail light I'm using. And since I built my own on/off switch I have no need to replace it yet.

This looks interesting!
What would be the effort to switch? I assume the cable is fixed to the lamp, not attached via a plug, right?

Yes, for both lights. So if you want to do it, it looks like you would replace both the light and the whole cable from the light to the dynamo. Then connect the tail light cable to the cable stump which has flat blade connectors.

Good find!
On the R&M site it only says "Hub dynamo Shutter Precision" so no idea but I would not expect ours to be better.
The way I read the graph in the cylclingabout article under "Results: Dynamo Hub Drag and Output Power Using Different Lights" ist that until 20 km/h is reached the SP has the least drag. That would be fine by me.
I am surprised by the total amount of drag though: Nearly 9 Watts (and half of that even with the light off) at 25 km/h is quite a lot. My average performance over an hour is about 250 Watts so that's 3,6 %. Cyclists have gone to great lengths to pursue smaller gains in efficiency.
Between this, the weight of my luggage and the excess weight on my hips atm I wonder how fast I could be without all that ...

Ok, that puts it very much in the luxury category then: Expensive _and_ labor intensive.
I will handle it like you: If the Supernova light ever breaks I will replace it with this.

Yes, interesting! I would expect ours to be different because this seems to be a big wheel test and SP offers different dynamos for small wheels, optimised for higher rotation speeds. So different, but not necessarily better. Anyway, for the Birdy it is a moot point since the SP is afaik the only disk brake dynamo hub that will fit the Birdy, because of the custom disk spacing it uses.

However I have another small wheel bike, and there the SON is an interesting option, because of the very low drag with lights off (which is most of the time). Their folding specific hub won't fit as it is 74 mm and has no space for disks, but they claim the SONdelux is "for road bikes and smaller rims" so it's optimised for high rotation speeds.

I would also like to see a test of the Shimano 1.5W hubs. They are small, lightweight and deliver half the power, but with higher rotation speeds of small wheels it might be enough. They would be a bad option for USB charging, though.
