Brompton rear mudguard installation and white trouser test

Brompton mudguards - its, autumn - we live in England and it rains!
So, its time to add mudguards to our Brompton
Previously we showed how to install the Brompton front mudguard - this time it's the rear one (on a Brompton with no rack)
Then to test how effective the mudguard was after rain - we donned a pair of white trousers and headed for some puddles!
The video is made of the following parts:
Installation of the Brompton rear mudguards
Testing the mudguards - with white trousers - at 8:06
Outtakes - where things went a bit wrong!
To be honest, we thought the trousers would be ruined - but we were amazed at how well the mudguards did,

Thanks for the very informative video, from this I found that my wife's Brompton did not have the right setup for her rear mudguard {as supplied by a Brompton dealer, who shall remain nameless} and was fouling on her rear tyre. Five minutes after watching your video the mudguard is in the right place and the wheel is spinning beautifully. Thank you very much, keep posting your brilliant videos.

Thanks so much for your videos it’s been a great guide for a Brompton newbie 👍

[@brilliantbikes]

Thank you so much for the kind comment - we really appreciate it We hope you have fun with your Brompton (we know we do)

Great video as usual! Helped me a lot. But I fitted rear guard to my B75 without removing the rear wheel. You need to fit the nut/bolt for the stays in the rear frame the other way around and deflation of the tyre is necessary to get the mudguard mount under the caliper. On the sprocket side tightening the nut and bolt for the stays is fiddly due to lack of space, but no more so than fitting the stays to the mudguard earlier. Other side is a doddle.

Thanks for watching and taking your time out to comment and leave the great tips Funnily we originally fitted (by mistake) the nuts and bolts the other way around - but wanted to make it as per the "Brompton setup"

How much all bits cost for putting mudguards please and any cheaper alternative for mudguards 🙏

[@christopherhood9241]

useful video - nice to see a dry bottom :

[@peterhill8374]

Your Brompton videos are really useful thanks

[@brilliantbikes]

Thank you so much for your kind comment - we hope you continue to enjoy watching them as much as we enjoy making them

I found your video was very helpful, thank you very much!

[@fernandojabalquinto1725]

Me gustan mucho tus videos, se nota que están muy trabajados y resultan muy prácticos. Gracias, y saludos desde Málaga(España)

[@brilliantbikes]

Gracias por mirar y por sus amables comentarios

Might be worth putting a piece of rubber or nylon/rubber washer between the stays and the frame to stop the paint coming away and rusting , great video btw.

[@brilliantbikes]

Good idea!

[@finncarlbomholtsrensen1188]

And (Don't mention it!) you are able to buy carbon anckor plates with small screws, from outside Brompton factories, of considerable less weight!!!

[@LordBillygoat]

Do you have a video to install the new rear mudguard and rack set? I've recently bought one for my A line but I'm too nervous to attempt it.

[@brilliantbikes]

Ah it’s on our list! Just not done yet!

[@roslee7]

7:04, whats the size of the allen key to remove or screw the wheel?

[@finncarlbomholtsrensen1188]

And being a "Rainy Dane" I would never use my bike without mudguards.

[@flogga123]

Very helpful video! Just wondering, do you know the bolt type and length of the bolts holding the mudguard stays in place? I've bought a 3rd party rack (similar to the H&H rack) and the bolts on my l-type mudguard will be too short to hold the rack in place too. I'll need to buy longer bolts, so any information would be really helpful!

[@alank1246]

Hi, your videos are great :) Just wondering - is the installation for the complete kit with the rack similar to this?

[@brilliantbikes]

Alan K thank you for watching and for your comment. It is similar, but different. It’s on our list to video.

[@tandago7281]

How is the "L-version" different from other mudguards? I am confused by this specification. Does it mean this doesn't fit with some bikes?

[@brilliantbikes]

Thanks for watching and the great question The ‘L’ means it has mudguards (but no tack) If it’s an R - it has mudguards and rack (the rack rear mudguard is different from the non-rack - L - version) The E version has no mudguards or rack Hope that makes sense

[@willyyawin]

Hi, at minute 2:10 can you tell me what is the size of the bolt and nut? Because my brompton was missing that. Thanks.

[@elverlands]

Is it possible to remove rear mudguard on M3L without removing the wheel?

[@gregmaciejowski4177]

Trying to fit the rear rack with mudguard on my SL2020 model. The mudguard seems to be very close to my wheel. The end points. No rubbing but very close. The clearance is about 2-3mm. Is that normal? Is there a trick to adjust it better?

[@brilliantbikes]

They are close on clearance - at the top of the wheel ... it helps keep the water away from you (occasionally you hear the grinding of a small stone as it passes through!) We have about 1cm of clearance where the end of the mudguard (flap) is

[@gregmaciejowski4177]

@@brilliantbikes Thanks you for your reply. I guess I could always bend the attachment points a little. Great videos by the way. Big fan!

[@buleminangmuarolabuah]

I’m gonna get my self a folding bike👍😀

[@brilliantbikes]

We would highly recommend them!

[@buleminangmuarolabuah]

@@brilliantbikes Thank you kindly and very much appreciated for you advice

[@Esqz33]

Definitely , you wouldn't believe how comfortable the riding position is on a Brompton.

[@CosgroveNotts]

Lol, this can't be serious. Comments on here do worry me that we won't get through the next generation for sure x

[@katecassidy6052]

Huh? What's weird about the comments here? It's just people talking about fiddly bike installations, not sure what part of that makes you despair for the next generation.
