Hello. We are leaving for our vacation in a couple days. I am bringing my Brompton and we're going to bring my 4.5 yr old son's bike. We are going to the Washington Coast where the sand is hard packed enough you can drive your car along the beach. The plan is to take off my son's training wheels for the first time and let him loose on the hard sand. That means I am going to be biking after him.

What kind of post-ride maintenance do I have to do to the bikes after our rides along the beach? Just spray down with water to get the sand & salt water off the wheels and frame. Then let air dry? Anything else?

Do I need to be concerned about sand getting into my rear shifter (I have an H6L)? Or will a good spray down fix that?

Thanks in advance.

Nobody here has ridden their folder on hard packed/wet sand before? Guess I'll have to take a pic of my Brompton in action on the beach and post it in the "folders in the wild" thread since I'm going to be a "pioneer".

Sorry I had to go to work.. you realize not everybody reads this site 24/7?

I'd wash the grit away with detergent soap and water , then re lube the chain..

If you had a Tank type chain cleaner to put the chain through a solvent bath that would clean it better ..


Park makes one and quarts of the fluid to use in it.

Blow dry , air-compressor is good for that.. oil, and then wipe off the excess..




of course you could turn it over to the team mechanic to do it for you..

I ride the rider paths on the beach and avoid the sand as much as possible. I replaced everything that wasn't Stainless with stainless and I still have to rinse the bike off with fresh water after every ride. I have found that using a wet-condition lube before the ride gives me a chance to abate any corrosion before I can get to fresh water.

wow, driving cars on the beach... sand filled with brake fluid, coolant, oil.... idiocy...

might be a good idea to google the nearest self-serve car wash location- the kind with the power-washer wand thingy. as soon as you leave the beach head straight over and rinse your bikes off. sand and salt are your enemies, especially with that lacquer finish...

carefull with ihg and bb, they would be expensive to sort out whereas a chains and cheap peadals can be binned cheaply.
airline suggestion sounds good or soak in something, take a chain sproket brush with you and a detergent of some kind.

NO POWERWASHER ......!!!! you gonna blow the grease right out of the freewheel and other parts...
warm soapy water and than rinse, dry with towel ( or compressed air, being careful not to do the same as the powerwasher .... meaning stay a little away from bike... ) re lubricate chain..... less is better than too much ...

1st time without training wheels? how far do you think he's gonna get?

Soap, water, leaf blower or shop vac on blow to dry, then re-lube.

Try not to submerge the bike in the water...you don't want salt water in your hubs, brake lines, BB etc. If you do, soap, water, dry, re-pack.

If it's a rental bike, you can skip all of this and simply watch for sharks as you try and pedal in the surf. :-).

In a case like this avoidance is better than remedy. I'd ride that Brompton to the bike shop and check out a rental.

got several answers to this .... but I digress .... lol

actually.. you are 100% right. just get rental bikes for the day. saves hassle and wear and tear on the brompton.

Thor, I know what you're thinking but we're talking saltwater sand beaches. I wouldn't ride any of my bikes on em'...

Thanks for all the responses while I was on vacation. Turns out that beach was not driveable (out of season), so we didn't get to ride/drive on the beach. I was expecting Long Beach, WA to be like Ocean Shores, WA where I drove my car along the beach a few years ago and the sand was hard packed and definitely driveable. But this the wrong season. Driving on the beach in Long Beach, WA is only allowed between Sept and Apr. Anyway, there was a nice paved bike path set back from the beach that we rode on instead.

So no sand/saltwater exposure to either bikes and the training wheels stayed on. My son got to experience short/steep rolling hills instead.

Driving at Long Beach, WA for those interested: https://funbeach.com/activities/beach-driving/

Sunset beach OR is a drive on *.. before the New Deal there was no 101 Highway , the beach was used as the highway .

so historically it is state /Publicly Owned .. WA property lines divide up the beach ..


*You can always drive a boat, aground, into the Beach, the sea quickly makes it imbedded in the sand .

glad you had fun, but honestly, "beach driving" is one of the most brain-dead, reality-denying activities i've ever heard of. the website says the activity dates back to the "earliest days of the automobile". seems to me it should have stayed there.

Driving on the beach in Ocean Shores was quite fun, actually. No lane markers, driving somewhere you typically don't drive, the ocean right beside the car window, getting a pic of your car on the beach, the sand hard packed enough not to leave any tread-prints. I would not do it for hours on end, but that 30 minutes was fun.
