I'm sure this must have been asked many times before but my search did not get me very far ......

Does anyone know where I can get hold of some bags that would fit a folded up electric bike? The bikes have 20" wheels and fold up close to where the pedals are. The idea is to lash the bag to the guardrails.

We plan to use a spare halyard to hoist the bikes onboard so they need to have a strong handle (the bikes weigh c20kg) but the main requirement is that they need to be fully waterproof. There are plenty of suitable sized bags that claim to be waterproof on Amazon but these seem far too cheap to resist anything more than a shower never mind the occasional bit of solid green water. I assume they will need taped seams like waterproof clothing.

Thanks for any info or any tips from anyone who has got bikes themselves :)

The boat is a Westerly Conway with reasonably wide side decks and the bikes are Wisper 806 step through.
 
Dahon make an official bag for their bikes - it's a bit oversize and loose for the Vitesse, which I think has 20" wheels. It's like a honking great shopping bag, but quite strong. They're not cheap new, but periodically come up on eBay much cheaper.

EDIT: just seen that you want fully waterproof ones - the Dahon bag does not meet this requirement. It's maybe splash proof if the bike is in it in the dinghy. If you want a waterproof bag I expect you'll need to get a sailmaker to tailor you one. ? ? ?

With the Dahon bag, I carry the Vitesse over my shoulder fairly easily, although I find it's only 12kg. I can then step down to the bathing platform and into the dinghy.
 
I have a filldo M1 pro, could not find a bag to fit, the 20” wide wheels and folding handle bar made it too wide, ended up getting some waterproof canvas and made a slip on cover to fit, works well. All the bags I found were just the wrong size for the slightly eider frame that the battery slid inside
 
We have decent bike bags - but for protecting the woodwork and upholstery below.

Don't think I have seen any bike bags that would keep out serious water strapped to the guard rails. And electric bikes tend to be expensive pieces of kit.

agree, I suspect a tarp tied securely over the bike cover will be the most straight forward configuration
 
I think your bikes will quickly be ruined .
But google found this which might be of interest

Difficult to see from the pictures, but any bag with a conventional zip will let solid water in at the zip. Would need a drysuit or similar closure, which I have not personally seen in any bike bag.
And folding bikes have lots of sharp edges. We have bits of foam padding to put over the worst edges, but even with very occasional use the metal tends to abrade the bag material. This will soon remove/puncture any waterproofing layer at the wear points.
IMHO cheap bikes can travel (and rust) on deck. Expensive bikes need to be below decks (whether in a cockpit locker or storage cabin).
 
Having made the bag we actually found it’s easier and quicker to fold the peddles jd handle bars and bring it down below, it’s sits quite well along side saloon seat, long but narrow and does not really get in the way whilst sailing.

Just bought 2 bags for our folding bikes from "bags4everything" in Wakefield. Great bags, great price. They were for Dahon bikes.
 
I know this is an old thread but now there are plenty of roll top expedition style fully waterproof bags surely it would not be hard to make one for a 20 inch folding bike or ebike. Not just to stow on deck but I want to take my bike ashore in the dinghy. I currently use a cheap folding bike as I know one day I will "float test" it, and I dare not take the folding e-bike aboard.

I have not seen a waterproof/ dunkproof rolltop bag off-the-shelf big enough for a folding bike, not even for my Brompton. So yes, DIY. Good idea. Have you got a pvc seam welder? Otherwise maybe inflatable boat seam adhesive. Following with interest.

If all else fails, I have an hypalon SBS bag that can be carried upon one’s back like a rucksack, or via other handles, that is large enough to accommodate an average sized human being.

It can be made smaller by evacuating air via a two way valve.

Water proof, inflatable, tough as nails (or hypalon), black in colour, very large, not usually available to the public, designed to carry two small (3,3 hp outboard engines at a guess) or one larger one.

Would not be cheap however because it is specialised and pretty rare to find on civilian market ( but would do the job and last for many many years - tough as nails - galvanised nails- 12 inch galvanised nails !)
 
Our Bromptons have been on board for 20 years, stowed below but left ashore in port. They are now seriously rusty, all chromed and non-chromed bolts, fittings etc look pretty bad. Chains and cables all replaced, seriously corroded. I think they have received pretty average care but the marine environment will always take its toll.

We bought ours new on 2004. They had some rust after 15 years of use, but not too much. We always keep them on the boat down below. I refurbished them in 2020 during covid. Sandblasted the frames and powder coated. New bolts, handlebars, mudguards etc. They look like new. It cost about £300 per bike for a full refurbishment. There are lots of aftermarket parts on Ebay including titanium bolts. No rust.
We have waterproof bags for ours made by my wife. They are mainly for storage but we also use them to transport the bikes ashore using the dinghy. They bikes have zero rust in the last 5 years sinc the refurbishment, mainly due to the waterproof bags.

Just negligence. We had Dahons from 1988 and Di Blasis from 2001 and never had rust problems. We kept them on the boat in bags, cockpit locker mostly, and at the end of the season I gave them a pressure wash and wintered them with a generous dose of WD40 and lubrication where needed.

I have a 1988 Brompton, had been used by a previous owner onboard his boat and I have kept it on board my boat, all seasons, for the last 11 years. Still works and looks good. Appart from tyres and chain, all original. Gets an annual service and clean.
