I spent a day in Arles mainly searching for my van that I had parked in an obscure car park. Prior to that I was admiring the fantastic Amphitheatre built in 60AD. According to Wikipedia it was built to hole 20,000 spectators and was the site for chariot racing and bloody hand-to-hand battles. I understand it currently hosts bull fights and concerts
This blog is the place to explore and comment on self-balancing wheelchairs in particular the Genny Mobility chair

Genny Mobility Factory
This visit was great - the team is young and keen and there is obviously vision and creativity for the future.
I was also delighted the headquarters are adjacent to another beautiful lake that proved to be clear, warm water and a great place to stay and to swim

From the surrounding countryside it looks like a citadel perched prominently in the river valley surrounded by mountains.

Zürich
I have been across the border into Switzerland on previous occasions but never stayed. After collecting my new batteries and on route to my next destination, I took the opportunity to visit Zürich and some of the beautiful lakes on my journey south

New batteries
Approaching 8,000 miles on my wheels I am conscious my batteries are nearing the end of their life. Genny's power unit is a Segway, complete with a pair of 72v 5.2Ah Lithium-ion batteries. Getting new batteries is complicated as they are consider dangerous goods. The movement of lithium batteries is subject to regulation by the International Air Transport Association. Segway going bust has added further complications to replacing my tired old batteries
After loads of research I have purchased a pair of ultra high capacity (UHC) batteries from a clever man who makes them in northern Switzerland. These are new batteries made with the same technology but a more modern build with higher capacity cells. To get these batteries I needed to drive across Europe and collect them in person
As I'm up for a road trip and COVID is starting to settle, and having been doubly vaccinated the world is opening again for me. Packing my VW van with mattress, cooker and of course my wheels, I set off for a grand tour and to collect my new batteries
These batteries are built into refurbished cases and there is a trade-in on the old batteries. They are made with a bespoke battery monitoring system that works in a slightly different way but still relies on the standard Segway charging interface. The usual charge indication shown on the Segway infokey reports it's level based on the use of the battery and measured by a built in shunt. The following image shows Genny having used 1/4 of its capacity
The new batteries don't have that same shunt monitoring system and are more variable in how they report their level of charge however they have considerably more capacity. This is of course dependent on many variables like terrain and weight of load. I understand these batteries have powered a Segway i2 for over 92km which is easily more than twice the usual capacity of the standard battery. What I can say is that in my experience, I have been able ride for much greater distance than my old batteries would have taken me. There will be more on this in subsequent posts where I try these batteries on the Comino de Santiago
This graph compares the normal 5.2Ah (yellow), a newer releassed 5.6Ah battery (orange) and the new Swiss UHC batteries (blue) and indicates an increase in capacity of well over 200%
Delighted as I am with my new batteries I will probably revert back to my old ones till they finally die on me

7000 on the clock
Today I made 7000 on the clock with my Genny. It's actually probably more like 8000 as I had a long time with another Segway base unit installed but using the same batteries whilst my gearboxes were being restored.
I'm definitely getting less miles per battery charge but that is to be expected. Its not a lot less but I have a target that I would always meet on a familiar route where the first bar on the battery indicator would go. Nowadays that indicator bar falls about 400m short

Having purchased a backup Segway I have a spare set of batteries, however they are older and less capable of holding a charge despite having minimal mileage. My plan is to get a new set of non- standard custom batteries when Europe is open for business again after Covid.

Segway Folds
What a sad end to this unique concept vehicle. First on the market in 2001 this vehicle has had such a mixed reception over the years for what is an amazing product. Apparently the total amount of sales since 2001 are a mere 140,000 units
How can such a cool device not be successful? Apparently Steve Jobs was quoted as saying it was "as big a deal as the PC" when it was introduced. In 2006 Segway discontinued all the earlier models and introduced the i2 and X2 models that used the leanstear as opposed to to a turning handlebar for steering. They upped the top speed to 12.5 mph and introduced regenerative braking
In 2015 the company was bought by Ninebot, a Chinese robotics company who were already producing a variety of personal transport systems including electric scooters. In 2014 they released a third generation of the Segway the i2 SE and X2 SE. These were principally the same as the i2 but with minor changes like lighting and a redesign of the frame and leansteer system
Apparently Segway sales only contributed 1.5% of the company profits and the high production cost, low sales and some bad publicity over the years are responsible for putting the iconic Segway to rest
Will this be the death of the various Segway powered wheelchairs like the Omeo, the add Seat, the Sui Gereris or the Going? I so hope not
Ninebot produce another 2 wheeled, self-balancing powerbase that is used as the core of other wheelchair systems, notable the Nino. This looks like a great chair and is well priced but doesn't have the charisma or style of the Genny

Built on the Ninebot power base, will this become the standard for the 2 wheeled wheelchairs of the future? - we can't even ask Steve Jobs any more

Gearboxes
I have found a company who specialise in all things Segway. The company is called PT Pro and they are based in Amburg Germany. They have been great at supplying various parts over the last year and I am starting to build a relationship with one of the engineers. Isn't it amazing that many Europeans speak fantastic English - puts us all to shame
PT Pro have a great website where they have many resources and are able to offer services that aren't available in the UK. Things cost a lot and postage from Germany seems to be expensive but they are quick to process your orders and parts arrive when they are due. There are many simple repairs and modifications that can be made by someone with very limited knowledge and simple tools. I have highlighted some modifications in my Genny Mods page
A small and easy modification I wish I had made 5000 miles back was to change the type of oil and add magnetic drain plugs to the gearboxes. These easy to change items have a small magnet that collects the tiny metal particles that get suspended in the Segway gearbox oil bath. These items are available through PT Pro and are likely to extend the life of your gearbox. The parts required are: magnetic drain plug and gearbox oil. You will need one magnetic drain plug and 70 - 80ml of oil for each gearbox of which there are two on your Genny
PT Pro have have great information about the care and repair of Segways particularly in relation to GEARBOXES and BATTERIES, They can also sell new wheels and tyres as well as being able to repair those delicate buttons on you Infokey
Here is a picture of the corrosion on my Segway driveshaft after being sandblasted to remove the rust. The pitting will stop any effective seal leading to a loss of oil which is not a good outcome for a metal gearbox.
Antigua 2020
The same familiar route enables me to leave home at 6:00 for a 7:05 flight morning flight. Collecting my wheels just inside the terminal I have time to shed some winter cloths, grab some hot porridge and a milky coffee before cruising to the departure gate. The usual discussions about lithium power cells and isolating batteries and I am boarded. The 8 hour flight arrives just in time to grab a quick swim before a fresh fish supper and several 'rum and Ting's'

Two and a half weeks swimming with colorful tropical fish and turtles in 27° water, fresh food and casual easy living is a great recipe for shortening the winter
I did a lot of small dingy sailing this holiday which was great fun. I first learned to sail aged 11 at school and have owned several dinghies over the years but have not sailed at all for at least the last 25 years. Getting back on the water under sail was a delight and Antigua, being one of the Windward Islands, was ideal. I was able to rent a small dingy from local National Academy of Sailing which was 4 doors down the road from where I stay. The Academy is based in Falmouth Harbour which is a a substantial area of enclosed shallow water ideal for sailing. Within 5 minutes I had capsized but was able to remember the drill and was upright again within minutes

Parts
As a backup I purchased a very low mileage second hand Segway at the end of last year (2019). It was a 2009 model and came with an 1 extra faulty battery. I was very cautious as that is old, particularly for the batteries, but I was reassured the see that it has less than 200 miles on the clock. It had had a very quiet previous life at a shortcut to the village pub
It was great to have a play on a stand-up Segway but my interest was mainly about it as parts. My mobility is now such that although I can get around in a limited way, I would be lost without my wheels
It turned out that this Segway was in fantastic condition apart from the batteries. I think at some point is had probably been left for a considerable period and that one of the batteries had dropped below a point it could be recovered. So this was why there were 3 batteries, one built in 2015 and the original 2 batteries that had been constructed in 2008 one of which didn't work
Although a shame about the batteries, the rest of the Segway was pristine so I changed the entire unit for my original and was cruising with less than 200 miles on the clock again. I had plans to rejuvenate my own unit and had another trip to Antigua lined up in February so needed something I could depend on
Another small modification I made was to change the cool looking tubeless tyre valve units for some proper inner tubes. Although less pretty to look at they have been fantastic and I haven't needed to check tyres since

chasing the tide
Jersey has one of the worlds biggest tidal ranges with over 12m on some spring tides between low and high water. The beach I normally cross is divided by a small rocky headland that is only navigable below half tide
If I miss the tidal slot I need to take the road which although generally quicker is not as scenic. I am forever chasing across the beach last minute trying to get past the middle rocks
Tidal flow is not linear and the fastest part of the tide is mid-range where the rocks divide the beach. Tearing across the sand I frequently end up crossing shallow water between waves from one side to the other
Dragging my wheels out of the soft sand through rising water is my worst nightmare
