Bike Hugger Buddy Flaps


by Byron on Nov 07, 2008 at 5:21 AM

Out of necessity, cyclists in rainy, wet climates use all sorts of inventive materials to create mud flaps for bike fenders. Old water bottles, duct tape, political signs, sump pump hose, and so on. Fender flaps are even a fashion statement. The purpose of the front flap is to protect your feet and in the back to protect your buddy from the spray, mud, and debris. On group rides, showing up without an adequate flap will result in a shunning to the back, strong comments, even getting yelled at because the spray from your rear wheel roostertails into the cyclist behind you.

Updated Update!

01/14/09 – We’ve got the flaps back in and they are en route to for fulfillment. We pulled a few aside to ship directly for those of you that have been waiting.

01/26/09 – the flaps are now available on

Flap Etiquette

It’s rude to not have a proper, functioning flap and the only excuse for not having one, is if it fell off while riding to meet the group. Even then, showing up without checking your equipment is cause for harrasment, but that’s another post.

Functional Flap

A functioning flap nearly touches the pavement, directs water down, and covers the fender’s width. It should have enough structure to not “flap” around or sway side to side. It should also have some style, like a custom logo flourish, truck driver mud flap woman, your alma matter, and so on.

Flaps were made by cyclists, because no one else was making them. Yes there were some fashion flaps, but none that worked in the driving rain until Buddy Flap started making their product.

Hugga Flaps

Last year Buddy Flap sent us a sample and after replacing my old sump pump tubing style flap, we ordered a batch with the Bike Hugger mark and a reflective strip (that’s the white in the photo and here’s a photo of the reflective strip lit up). Andrew posted on their arrival at Hugga HQ earlier today and I posted the photos on Flickr.


We’ve got a dozen of these and if you’d like to purchase one now, let me us know in the comments and we’ll invoice you directly. Cost is $15.00 + 2.50 shipping (tax where applicable). They’ll show up on our Amazon store in a week or so. We’ll need your email to invoice you – note we’re not spammers or email list sellers.

To install the flaps, drill a hole in your fender a few inches up from the bottom. The flap is shaped like a fender and flares out for max coverge. Install it inside of the fender and bolt it down tightly.


A true test of a flap is to survive a ride atop a car on a rack at highway spends. Many handbuilt flaps have failed this test and the reason I used sump pump tubing. Buddy Flaps could use more structural ridigity, but should survive a car trip.

Hope he’s using a better adhesive on the reflective strip than in the past. I got a set with reflective strips about three years ago and finally peeled off the remnants this spring. Problem is all the flexing the flap does lets water and dirt get under the strip, then that’s all she wrote…

Good tip, and 3 years sounds like a long time for a flap. I’ll report if I notice any strip failures. I did comment in my post about the flap needing more structural rigidity.

I’ll take a set.


Oh! Oh! Oh! Pick me! Pick MEEEE!!!

Yes please!

Portland, OR daily commuter seeks flaps to reduce spash-age on those that draft behind my portly frame.

I’m about to order a rain bike and would love to pick up a set. (already ordered long honjo fenders for the upcoming boke)


I think that’s our craigslist ad verbatim! Check your email for an invoice.


Rock—invoice sent. At this rate, maybe not even have to send these to

Hi DL,

Count me in as well!



Will do.

Love a set if you’ve got any left.


Invoice sent!


Wow! Shipped already, even! Thanks!

If you still have any, I’d like a set for winter commuting in Minneapolis.


Invoice sent—two flaps left in inventory.

Yeah, it’s starting to get nasty around here. I’d like a pair if you have any left.

PS - Are you invoicing via Paypal, or…???

Yes—paypal invoicing.

One flap set left!

I’ll take the last set.  Living in SoCal I might not get much use out of them, but they are cool, so I want a pair.


Invoice sent and awesome all sold.

Thank you.

Got my set on Friday.  They are awesome!

Any chance you will have more for holiday shopping?  I would love to get a set for my boyfriend!

Yes—we’ve got more on order and I’ll check now for a “rush.”

Rush order is on the way.

And we’ve got more hugga flaps in; unfortunately with the roads here in Seattle we didn’t get them in time for Xmas.

I’m waiting for the aero buddy flaps.

and all carbon with ti hardware.

would like a rear one, unsure front would work with long honjo fender

Jerome—sorry we just sell them as a package, but Matt one of our readers, reported that he installed them with Honjos.
