I think there are different issues here.
The data that is sent via Bluetooth will have data-checking built in. In other words, if the signal is strong enough it will receive the data correctly, with no 'false' readings. If the signal isn't strong enough it won't record incorrect data.
So for example in a supermarket the fluorescent lights and other electronic equipment may make the Bluetooth signal too weak (or relatively weak), so it may not receive reliable data - in which case your HRM lrecord zero (or - better - 'not avaliable').
So with the HRM I think the problem is with the sensor itself - it is picking up tiny electrical signals from your skin and amplifying them enough to count your heatbeats. That's where the electronic buzz in the supermarket will be affecting things - nothing to do with Bluetooth.
OTOH I'm baffled why your cadence sensor went beserk in a supermarket - did you take the bike in?

Re: Flying bikes back from Tirana Airport
I think €20 for a box is OK. I have been charged €25 in the Canaries and €30 at Nice airport.
I did fly back from Tirana a few years ago, but that was part of a CTC tour (sadly now defunct). The tour organisers arranged boxes for us.

Re: Avenue Verte (French section)
I just took the charger with an adaptor for the campsite power points (ones used by caravans etc). I don't think any sites charged me to use the power points if I told them it was just for the bike charging. Sometiimes though I didn't ask . Sometimes I used a normal powerpoint in a washroom etc.

Thorn Mercury - 56/58cm - Option of added motor
I am re-listing this because I made a mistake with the frame size. I now know that it is a '58s' according to the Thorn guide (http://www.sjscycles.com/thornpdf/BUILD ... OHLOFF.pdf), so in theory should fit someone taller than me (I'm 175cm)
I added the motor because I was having problems with fully-loaded touring. Everything works (I rode Dieppe to Marseille and beyond with this setup 18 months ago) but I find the weight (nearly 22kg without luggage) just too unmanageable for maneovering etc. I'm only 58kg myself and over 70 years old now. I'm planning to use a lighter weight e-gravel bike instead.
I'm able to sell it in either its current mode (with battery and motor etc ) or in its more original state (I can remove all the electrical stuff ) but would prefer the former.
The Rohloff hub (which has recently had an oil-change) is controlled by a Giles Berthould rotary changer. As pictured, the front fork is steel and has an Avid mechanical disc brake (as per the back wheel) but I also have a carbon front fork with rim brake - if I sell the bike it will be supplied with both. If without the motor, the front wheel that I have will be rim-brake only.
I haven't cleaned or tidied it up for sale. If I can't get a reasonable offer then I'll probably keep it, but otherwise it's taking up space and will get used rarely.

Re: Avenue Verte (French section)
I did it in August 2022. Short ride the first day to a nice campsite next to the route at Neufchatel-en-Bray, Then a long day to the outskirts of Paris where I stayed in a cheap hotel.
I used a Rohloff touring bike with added e-motor.
Very easy ride, good surfaces, reasonable scenery.

Please maintain OpenStreetMap (easy to do). It is OUR map. It is used by many bike routing apps. It has places for opening times but no reviews - just facts. I never use Google Maps and do not have an account.

Re: Between Andulucia and Algarve
OP Postscript.
Today I took the ferry from Alcoutim (Portugal) across the river to Spain. So it does run in March (seemingly every half-hour) and it does take bikes. 2.50 euros.
I did a one-day round trip, crossing back into Portugal via Mertola. Only a small sample, but Spanish roads have better surfaces than Portuguese ones!

Re: Thorn Mercury - Rohloff - 54cm - electrified (or not)
Not really sure. I bought it for £1000 about 3 years ago. Since when I have aded a new fork and front disc, mudguards, new eccentric BB (the original one was jammed), new bar tape etc.
I have ridden about 6000 km on it, about a third of that with the motor kit.

Re: Thorn Mercury - Rohloff - 54cm - electrified (or not)
Thanks for asking.bikes4two wrote: ↑28 Feb 2024, 9:13pm I'm asking mainly out of curiosity really as the frame is not my size but potential buyers might interested to know what hub motor is in the front wheel (brand, power rating, voltage) and what voltage and Ah is the rack mounted battery please?
Also curious as to the item secured to the seat post?
Thanks.
The motor kit is from Woosh (https://wooshbikes.co.uk/?hubkits#xf07), with a rack battery (17Ah I think) . 36V .
The item on the seatpost is the display unit for the motor (King Meter) - it is of course supposed to be on the handlebars, but the bracket supplied will only fit on straight bars so I mounted it under the seat. It's only needed to check battery level and to change power levels. Since I always ride it with level 2 (out of 5) I never had to look at it much (or press any buttons, except when starting a ride).

Thorn Mercury - Rohloff - 54cm - electrified (or not)
Just wondering if there may be any interest in this, in either its current mode (with battery and motor etc ) or in its more original state (I can remove all the electrical stuff).
I added the motor because I was having problems with fully-loaded touring. Everything works (I rode Dieppe to Marseille and beyond with this setup 18 months ago) but I find the weight (nearly 22kg without luggage) just too unmanageable for maneovering etc. I'm only 58kg myself and over 70 years old now. I'm planning to use a lighter weight e-gravel bike instead.
The Rohloff hub (which has recently had an oil-change) is controlled by a Giles Berthould rotary changer. As pictured, the front fork is steel and has an Avid mechanical disc brake (as per the back wheel) but I also have a carbon front fork with rim brake - if I sell the bike it will be supplied with both.
I'm in no rush (in fact I'm away from 1st - 15th March), and haven't cleaned or tidied it up for sale. If I can't get a reasonable offer then I'll probably keep it, but otherwise it's taking up space and will get used rarely.
No, I don't know why the saddle is like that - it's not my usual riding position - wish I had noticed before taking the photo!

Re: North coast Spain west, Santiago, Braganca, Potes
What are you getting at here? I live in Cornwall and have used the Plymouth ferries loads of times (although more to France than to Spain, I am booked to Santander again at the end of March - first one of the year)!MrsHJ wrote: ↑22 Feb 2024, 7:40am
..... I think maybe people from Devon and Cornwall like to use the ferry from Plymouth and then the Cornish folks drop out as they’re too tight and hence we’re all from Devon and cycling in Northern Spain! I guess if I lived in east anglia the Harwich ferry would be more appealing.

Re: Should electric bikes go faster
One aspect which hasn't been mentioned yet. Although I wouldn't sign a petition for faster e-bikes, I sometimes wish that I had one! - I bought a light e-bike partly with the intention of being able to keep up with club rides as I get older. Fine, I can now keep up easily when it's hilly. But on a long stretch of flat, or slightly downhill, I get left far behind because the group is going at 20mph or more and I am left struggling - even though I've saved some energy on the previous hill(s)!

Re: touring wheels upgrade
I'm 60kg and often tour with 10-15kg luggage. I have toured on many different bikes, with many different types of wheels, some of them very lightweight (though not carbon). Apart from the occasonal puncture in the last 10 years I have only twice had a 'wheel' problem:
- once on a hire bike (a quite heavy 'touring' one) in Majorca - a broken spoke which then got tangled in the derailler (that was messy and I had to call the hire shop for a rescue);
- once on my 35-year-old Gawes Super Galaxy; a broken spoke in Holland.(The wheels weren't 35 years old but had been replaced with something similar to the original). The wheel still worked OK until I got to a bike shop who replaced the spoke in 5 minutes.

Re: Boost Conversions
I'd not heard of Boost conversions before but having looked at the website it seems pretty good. Yes the battery is small but not much different from systems like Fazua and Mahle. And the spare bateries are half the price of those.

Re: Flight-Free Holidays
I've seen this mentioned in so many places relating to green issues. As I understand it, it's because there's no tax on air fuel, unlike on deisel etc. But trains are also very heavily sibsidised. I have lost the links now, but a few months ago I looked up the state subsidy for rail travel in UK, Germany and France - in all cases the subsidy was equivalent to the amount taken in fares.
I'm not condoning air travel by mentioning this; I would just like to know the real reason why rail travel (for international routes) is so expensive compared to air.
Another related aspect - if all the people who currently fly to Spain / Portugal etc for holidays were somehow be persuaded to go by train, how many extra HS2-like railways would have to be built across Europe, at huge environmental cost, to accommodate them?
I conclude that the problem isn't really about flying per se, it's more about travelling at all.
