Flying with your Genny

Genny is a great travel companion. It will get you places you may not have the energy to access without it and with such a great range on a battery charge it can replace a hire car to some extent. And what style, it will raise eyebrows and get you into many interesting situations and discussions  

We know however that going anywhere with a wheelchair may have additional considerations and getting your wheels into the air can be quite an ordeal. With a motorised chair the issue is more than likely to be about the batteries

Genny comes with 3 batteries. The first is a small 12 volt old school lead-gel battery like you would get in a small motorcycle. The other batteries drive the Segway and are a pair of 5.2 Ah, 73,6  volt Lithium-Ion batteries made with 92 cells each. Lithium batteries have proved unstable under certain conditions and there have been fires on planes because of them. As far as I am aware Segway batteries have proven safe

The movement of lithium by airplane is governed by the International Air Transport Association (IATA) regulations. If your wheelchair is powered by lithium batteries the details are covered in their "Battery Powered Wheelchair and Mobility Aid Guidance Document (updated 2021)" This document is definitely your friend. Print it out and always carry it with you when flying. I also keep a link on my phone just in case. Many times I have needed to resort to this document in discussions with ground operations representatives at the departure gate. I have also spoken to several pilots who have always supported my transportation when referencing the IATA regulations

The issue is that everybody and his mate has an understanding of what the regulations state. From the staff at check-in, the disability advisors on the phone, to the captain, all have their own interpretation and most of it is negative. The word Lithium is a red flag in aviation so have the IATA guidelines printed out and at hand

Once you get past the lithium issue there is another specific design floor with Genny that will also cause havoc. I have several "Acceptance for Travel Guidance" documents that are available on my RESOURCES page that give Genny flying instructions. The problem bit is with the small control panel that puts your legs down. After activation the lights on this unit stay on for up to 8 minutes. This is 8 minutes with the ground operations team twiddling their thumbs and waiting till the lights go off. It is also 8 minutes with you in your aircraft seat watching out the window as they all have a play trying to make the lights go out. Every time someone touches these switches, the 8 minute counter is reset and starts again

Legs down switch control panel

I have 2 solutions for this issue. The first is a small plastic food container that has been adapted to fit the control panel. The switches are then protected and beyond reach of impatient baggage handlers   

Switch protection using a modified food container

The second and much better option, is to fit an additional switch into the 12 volt battery lead that completely isolates the Genny power source. This is a fantastic modification that instantly puts Genny to sleep to the delight of the ground operations crew. This is obviously not an official Genny modification but will greatly assist in airport situations. I have this hidden under the seat and directly above the battery as shown below. Anyone with a simple understanding of electricity would be able to install something like this and it sure beats trying to convince people to wait the 8 mins till the lights go out by themselves. It also helps with children who just can't resist pushing buttons. If you want more details of this solution please leave me a message in the comments space below

Another very useful addition is some small wooden inserts I have fabricated. These fit into the side handles that you lower if using a sliding board or to put the legs down in emergencies. These are visible in the following photo and are held in place by 3 cable-ties. I use these just in case a loader accidentally operates these handles. With the legs down Genny is very difficult to move and every time it is lifted, the legs come out more, making it even harder to move. If you want the pattern for these please leave me a message in the comments space below. This would be a good item to get 3D printed

Segway Folds

So finally Segway is ending production on 15th July 2020

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

The Nino

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

Traveling across the beach on wet and salty sand inevitable leads to corrosion of metal parts. The most vulnerable bits on a Segway are the gearbox drive shafts. The shafts emerge from the aluminium gearbox case through rubber seals. Corrosion on the shafts make for leaking seals so with a replacement core Segway fitted to my Genny (see previous post) I have sent my old leaking gearboxes off for repair

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

How fantastic to be back in winter sunshine and warm water again. I love this island, it's another world and a home from home. Being my 4th visit and on such a noticeable vehicle I am now well known on the island. To see my other Antiguan posts follow these links: 2018, 2019

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

In the uncertain time when Genny Mobility was not in production I decided it was a good idea to get what parts I could together to keep my Genny running. My gearboxes were getting increasingly noisy and although I had changed the oil and various other components in the drive train, they were a worry

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
