Folding Bikes

I would look for some used Dahon foldables. The price of new ones have gone thru the roof but they are nice quality bikes. Almost all bikes of any kind have gotten considerably more expensive since the pandemic shut down of factories.

I bought two folding electric bikes for the same reasons as you. One season of moving them in and out of our 5th wheel and it was over. The bikes now stay home.
I don't recommend buying bikes if you are planning on storing them inside your 5th wheel.

Not going to store them there, just transport them.

We have a couple from CW. Bought them on sale and they are decent bikes. Have them for about 5 years. Don't know about the ones they have now. Just used to ride around CG and short rides. Carry them in truck normally. Did carry them in the TT once but too many sharp edges. Afraid they would break free and do some serious damage.

We had the folding ones from Caming World, stored them in the basement. They ride and worked well. Just replaced them with recumbent trikes, otherwise we would still be riding them.

Dahon makes a very nice quality folding bike.

I'm like you. Why carry nice, expensive bikes on a rack attached to the back of your RV, where plenty of dirt, grime, and debris can wreak havoc on them? If that was my only option for carrying bikes, at least I'd have to fashion some type of enclosure/covering for them.

Why limit yourself to folding bikes? Take the front wheels off, take the pedals off, put down an old blanket on the bed and lay them down on there. 10 minute job to do that. Then you have your choice of what you want to ride instead of being limited to something that you think is more convenient but really isn't.

I have a Dahon as well and love it. It's only takes a second to fold or unfold and its well built and rides quite nicely. Prices have gone up lately, most likely due to the tariffs, but you can sometimes find them on Craigslist.

We had a couple of Dahon foldables for several years and liked them very much. Well made and not too uncomfortable to ride.

I have an old pair of Dahon with 3 speed in the hub which is nice because the chain is less of a mess. They fold much smaller than the CW and have the same 20” wheels. I will sell those since I have too many bikes.

I also have a pair of 6 speed CW bikes that do a better job if you have any hills. Quality is just OK. Be aware that CW is/was selling folding bikes with 22” tires that are next to impossible to find replacements.

Whatever you buy, be sure to get bags for them. I place the folded bike on a cheap HF furniture blanket then pick the blanket up and lower it into the bag, that gives extra protection to the bike, bag and vehicle.
