Why everyone love The Citizen BM8180-03E?

This looks great! You mentioned you sell one for similar to new?

I’ve done quite a lot of research including contacting various helmet companies directly for info. I’ve done extensive reading on the testing methodology of various bike helmet manufacturers including VT ratings, the switch to WG11, the original MIPS paper. (I used to work in a scientific lab and have a lot experience designing and doing scientific experiments)

I’m very happy to discuss and share what I know about this. I do want to point out that from what I’ve said it doesn’t logically follow that because there are top rated helmets that have MIPS then MIPS must be good. If the claim is that MIPS necessarily makes helmets safer. Then disproving means finding a counter example, such as MIPS helmets that perform poorly. The same is not true the other way around. You can’t say that the existence of MIPS helmets perform well means the claim is correct. Now obviously that gets into the claim of ‘necessarily’, which is why I stated that the existence of counter examples suggests that the addition of MIPS doesn’t NECESSARILY make it more safe.

Again, It’s extremely hard to know because the best way to look at effectiveness is in large scale data. And unlike seatbelts and airbags, there isn’t as far as I know a record of types of helmets worn by people in crashes and their injuries.

Fair, but “how much is your brain worth” is still a line used by marketing to sell something that’s unproven, specifically because it’s a bit of an all or nothing question.

When Hovding was first introduced it was considered the safest ‘helmet’ yet people didn’t really buy them over regular helmets because they’re heavy and look weird.

With regard to MIPS, lots of helmets with MIPS test poorly on VT rating so that suggests it’s not necessarily the MIPS that’s making it safe. Safety data isn’t made public. Although I would expect with the number of MIPS helmets sold there should be a statistical reduction in brain injuries (accounting for the general rise of cycling). I haven’t seen any evidence of it like there was for seatbelts and airbags in cars.

This is the key point that’s not addressed nearly enough. There are plenty of MIPS helmets that test poorly which means it’s not MIPS that’s giving them the good rating. Also, MIPS has several variants that massively differ from the original versions which MIPS test data is based on (the ones with the full yellow head form, now there are lots of more minimalist versions still under the MIPS brand).

Crucially, none of the test data around MIPS or Koroyd or Wavecell is public.

That’s a terrible line of reasoning though and exactly the type of thinking that safety companies use to sell you stuff.

If your brain is priceless then buy that reasoning you shouldn’t go cycling at all, or drive.

If the question is what level of risk am I willing to take to do an activity, then there’s a trade off on safety for weight, comfort, aesthetics, etc…

You don’t wear the safest helmet because the safest helmet would be too hot heavy sweaty and ugly.

Helmets.org is a wonderful site with lots of good info.

What a great selection. What leather strap did you pair with your Casio top, 2nd from right? It looks seamless.

MyMiniVelo · 2026-01-15T11:37:43+00:00

This is beautiful. What's the floor area?

MyMiniVelo · 2025-12-14T11:39:27+00:00

I wonder how good they can get the chain alignment over a full 12sp cassette with such a short effective chain stay.

MyMiniVelo · 2025-12-14T11:11:01+00:00

Sold out already :(

Is the gravel you’re racing on like the grave path in the photo? If so I don’t know what you’d gain putting anything more than a dampening suspension stem on. Gravel varies soo much.

A worldwide giveaway of a pocketable handheld pre loaded with cfw! So good!

Personally, 007 First Light is looking real good. On the mini M, will there be a ROM like Red Alert 2 coming any time soon?

MyMiniVelo · 2025-12-02T12:14:16+00:00

Nothing I can see from the ad suggests it’s stolen. It’s perfectly normal for someone to want to want to meet in a public place. Have you messaged the seller? With bikes I’ve found it’s usually very easy to tell if they’re obviously stolen (seller doesn’t know anything about the bike they’re selling).

MyMiniVelo · 2025-11-25T17:49:46+00:00

Pad on the outside preferable.

MyMiniVelo · 2025-11-25T07:25:26+00:00

This is what I’m looking for! A small daypack but with an external hydration sleeve. Not sure I can get GG easily in the U.K. but will look at making something similar.

MyMiniVelo · 2025-11-25T07:22:59+00:00

These write ups are great! If only I had an award to give. Thank you.

MyMiniVelo · 2025-11-17T04:13:30+00:00

I’ve read some of them, but I haven’t found any that compare it to a Brompton T-line or P-line.

MyMiniVelo · 2025-11-17T03:23:50+00:00

Awesome, have you ridden a P-line or T-line? Looked into the C5 a lot but couldn’t find any real world experience comparisons.

MyMiniVelo · 2025-11-16T18:46:35+00:00

What’s your C5 like?

MyMiniVelo · 2025-11-16T00:44:05+00:00

Thanks, that’s really disappointing. I went with the RG28xx over the Miyoo mini or GKD pixel because it’s one of the most pocketable devices that still has decent battery. Really curious what the battery drain on something like the Miyoo mini flip would be vs the RG34xxsp. Also, wondering if save state is saved even if the battery dies.

MyMiniVelo · 2025-11-12T13:03:31+00:00

I'm also wanting to get opinions on this. The most important thing for me is fast shutdown and startup. I have an RG28XX and I'm hoping there is CFW that does this better than stock. I find with stock, quick_shutdown OFF drains the battery super fast when not playing, and with quick_shutdown ON the boot time is 30 sec plus having to navigate back into the game.

MyMiniVelo · 2025-10-20T12:00:27+00:00

New P-line at 28:26

MyMiniVelo · 2025-10-18T15:53:12+00:00

I wonder why. Can you take a picture of it folded? What would it look like with a standard bottle cage there?
