“Behold,” boasted the electric vehicle (EV) company Nikola. “The 1,000 HP, zero-emission Nikola One semi-truck in motion.”
The claim was technically true. The lorry was indeed moving. But as the Arizona-based start-up admitted last week, it was moving because it had been towed up a hill and then left to roll.
“Nikola never stated its truck was driving under its own propulsion in the video,” a spokesman defiantly declared. “As Nikola pivoted to the next generation of trucks, it ultimately decided not to invest additional resources into completing the process to make the Nikola One drive on its own propulsion.”
After the admission forced Nikola’s chairman and founder Trevor Milton to resign, shares in the company plunged on Monday.
It’s almost over. Tonight’s (Aussie time) brings le Tour de France to its conclusion on the Champs-Élysées in gay Paris. The race for the yellow jersey is done and there are no more mountains. It will be a field day for the sprinters and a celebratory procession for the rest.
I have watched it on SBS with all the passion of the born again. The commentators Robbie McEwan, Matt Keenan and Bridie O’Donnell have done a splendid job although some coaching on their pronunciation would not go astray. To call a water bottle a bidon is in keeping with l’esprit de la course but to pronounce it “bidden” is a travesty, not to mention the gender and ending scrambling.
I am certain that the riders are pleased to be reaching the end after 3,483km but I’m wondering how I will fill the void it leaves behind.
And what a finish. Stage 20 was a time trial, a mere 36.2km long but ending with a brutal climb. Team Jumbo Visma had led their star rider Primoz Roglic to the very threshhold of victory. He’d worn the yellow jersey for 11 days. Breathing down his neck was another Slovenian Tadej Pogacar, a debutant in the tour and 22 years old tomorrow. It was Pogecar that rose to the occasion. He gets to take home the Yellow Jersey as overall winner, the White Jersey as the best young rider and the Polka dot Jersey as the King of the Mountains. All he needed to be happy was just to take part!
Meanwhile Richie Porte from Tasmania was in fourth place behind Miguel Lopez and breathing down Richie’s neck was Mikel Landa. He had to recover a minute and a half to overhaul Lopez and ride well enough to stay ahead of Landa in the process. He knocked it off at an average speed of 37.5kph.
Kudos, Richie, kudos. He will be just the second Australian to mount the TdF podium.
Stage 21 is for the sprinters. Can Caleb Ewan, the only other Aussie, add another stage win to his collection and repeat his achievement of last year?
Youth would be an ideal state if it came a little later in life.
For night riding the bike was equipped with an acetylene light mounted from the handlebars using a sprung trapezoidal frame. The light had a lower compartment to hold carbide and a water compartment above to allow a regulated drip through to the carbide which generated acetylene to be burnt in front of a reflector to supply light.
Kel bought his first bike in 1937 …
with money earned from delivering morning newspapers. This was the only time that I can recall my father being angry. He seized the new 24 inch wheel bike and later returned with a 28 inch bike that I would not grow out of. I rode this bike from Westgarth to Preston for school for three years. On wet days I used a waterproof cape which extended over the body and forward over the handlebars.
He joined the scouts …
In the early 1940’s, preparations were made in anticipation of Japanese air raids and the Air Raid Precaution Organization was formed. Various scenarios were practised, using scouts on bicycles as messengers to relay information between headquarters and “bomb sites”. In other scenarios, the scouts were used to play the part of injured civilians who needed first aid and to be transported to hospital. My family did not have a telephone at this time, so a person living in Regent was rung to pass a message to his neighbour (another scout messenger) that his services were required at Air Raid Precaution Headquarters. This scout would jump on his bike and collect me en route to Northcote Air Raid Precaution Control. The Scouts were allocated roles as messengers or the injured.
During these war years new tyres were not available so we learnt to retread our own tyres by spreading a rubber solution over the tyre and sprinkling the tyre with crumbed rubber. At night, the suburbs were blacked out to prevent any enemy aircraft from identifying the geography of the city. Even our car and bike lights conformed to blackout rules by having shields to cover the front light and thereby permitting only a glimmer of light to escape.
About this time, my paternal grandfather came to live with us and he took to riding my Dad’s bike. I was amazed! He was 81 years of age and still able to ride a bike!!
The bicycle is fun for kids but to most adults of Kel’s generation it was merely utilitarian. The motor car slowly took over. Eventually, though, Kel and his wife, Gwen were blessed with grandkids and they seem to have been a catalyst …
Many years later our young granddaughters were given small bikes, our daughter, Helen, received a new mountain bike for Mother’s Day and I was given a hybrid aluminium bicycle for painting their house. I joined a Bicycle Victoria event and along with my five and six year old granddaughters we rode from Carlton for the 50 km over the Westgate Bridge to Williamstown and back through Footscray to Carlton. Then when the girls were aged seven and eight and I was 77, we completed our first Great Victorian Bike Ride from Port Fairy to Geelong and never once walked nor required the sag wagon! I continued to participate in the Great Victorian Bike Rides for a further six years.
After six years on the hybrid, I changed to a Jamis, steel framed road bike, but changed the handlebars from flat to butterfly bars to give me a better hill climbing attitude.
By 2015, my wife, Gwen’s health deteriorated, necessitating her move to an aged care facility and I began riding my bike the 5 km from Eaglemont to Alphington every day to visit her. Looking for a new activity, I signed up with the Banyule Bicycle Users Group (BUG), made up of a group of retired men and women in their 60’s and 70’s. I was then 87. Banyule BUG ride two days of the week, travelling along bicycle paths, roads with bicycle lanes and some minor back streets over distances of 30 -95 km
Arriving home and feeling tired after the Banyule BUG ride, and still with another bike ride ahead of me to visit Gwen, I began to look for an electric bike. I chose a CUBE brand, step through frame with derailleur gears. I ride this bike in the evenings to visit my wife. It suits the hilly terrain when I have a heavy load and I am feeling tired. The ebike is heavy and ponderous and I find my road bike much more responsive so I prefer it for the weekly BUG rides.
At nearly 93 years of age, I enjoy my bike riding and look forward to active, safe riding for the next few years.
Amen to that and thank you Kel for taking the time to contribute this blog.
Ask a policeman.
When I was a lad in England this was a popular song often played on the wireless. My father, a policeman, would tell me that it was evidence of the trust we placed in the men in blue. If I were lost or just wanted to know the time I could safely approach a policeman.
In fact the song was written by Edward William Rogers in 1888 and was a monster hit in the Music Halls of the day for Mr James Fawn. In runs through five verses and choruses of innuendo that the audience of the day would have latched onto in a flash.
The first chorus sets the scene …
If you want to know the time, ask a policeman.
The proper Greenwich time, ask a policeman.
Every member of the force has a watch and chain, of course,
How he got it, from what source? ask a policeman.
The police were drawn mostly from the working classes and paid a meagre salary how could they afford a watch and chain, expensive items in those days?
If you didn’t click the link above do try it now and if you’d like to learn more of the song’s history and see the full lyrics there is an excellent site <HERE>.
But those days are long gone. So much has changed. In those days you could ride a bike without a helmet, a deristricted sign meant that there was no speed limit, the police couldn’t stop you without a reason, there was freedom of movement, freedom of speech and freedom of assembly.
One thing that hasn’t changed is the regard in which we hold the police. Christine Nixon, former Chief Commissioner of Victoria Police did her bit by lying to the public about the role of African gangs in Melbourne’s crime statistics, topped off by going out to tea with her phone switched off as Victoria burnt one Black Saturday. Simon Overland, former Chief Commissioner, was in charge of the Purana Taskforce during the period that Nicola Gobbo, lawyer to the stars, was informing on her clients. Graham Ashton, former Chief Commissioner, has just been excoriated by a royal commission for suggesting that such outrageous behaviour passed “the pub test” because it was all in a good cause.
The present Chief Commissioner, Shane Patton, has shown himself excellently well qualified to run a Police State. His force managed to subdue and handcuff a pregnant woman in front of her children in her own home for a facebook post. I understand that she may be facing a 15 year jail term. Well serves her right, she should have organised a Black Lives Matter rally or a union protest both of which are exempt.
Mr Patton has resurrected or borrowed or invented the offence of outraging public decency. He should be careful with a hairstyle that does just that.
Welcome to China, have a nice day. It must be part of the Belt and Road agreement.
I happened upon an interesting video which reminded me of an incident in my own illustrious career. First the video …
In the hope of a holiday in hospital for a change of scenery and routine prisoners will occasionally harm themselves … in a calculated way . When I was a resident a prisoner was admitted who on x-ray had knife, fork and spoon plus a couple of coins making their way through his alimentary canal. He was otherwise well and in no discomfort.
This being Australia a sweepstake was immediately commenced among the hospital staff. Our money went into the kitty. I drew a blank so no chance of winning. Those fortunate enough to draw an object waited to see what would emerge first.
To everyone’s surprise it was a toothbrush that hadn’t been picked up on x-ray. It was followed by the coins and cutlery. No active treatment was required.
It was a warm one yesterday. Late in the winter that can only mean one thing – a north wind, and to make sure we noticed it blew up a gale last evening. Not too much of a mess this time.
Today the weather is perfect, cool, sunny and just a light wind. Ideal for a ride with my very own Gayle at the end of which I checked in with Strava to find that I’d climbed 8,750 meters for the month. If I really was climbing Mt. Everest I’d be at the South Summit. That is very definitely in the death zone, no place to linger. So I got back on the bike and rode off to my favorite hill.
The Cornice Traverse is a knife-edge. On my left there is a drop of 2,400 m down the north-west face, to the right 3,050 m down the Kangshung Face. Getting the bike up the Hillary Step is a bugger of a job but …
It’s done, 8,848 m. It took me 21 rides over 27 days. The current record holder is Ronan McLaughlin. He did it in 1 ride of 7:04:41.
Early this month it looked like the state of Victoria was going to be sentenced to house arrest again. I quickly got in a long ride that I thought would be my last for a while.
There are only four reasons that we may leave home and whilst one of them is for exercise it seemed for a few days that we would all be restricted to one hour a day within five kilometers of home. That became the reality for the majority – those that live in the big smoke. Out in the sticks we were allowed greater freedom. We can exercise longer and go further.
The prospect of an hour a day got me thinking of how to avoid a crash in my fitness. I resolved to up the intensity making repeated use of a local hill. When all was clarified it still seemed a good time to chase the Strava Climbing Challenge of 7,500m in a month.
I wrote about the phenomenon of Everesting back in May. So this month has been a serial mini-Everesting. (In the interim the rest of the cycling world has moved on to Trenching – 11,034 meters, the depth of the Mariana Trench. Yes, in a day).
Since I wasn’t restricted to 5km I could make use of a better hill than the nearest one. There is a Strava segment not too far away called Devil’s Peak. It sounds more impressive than it is. The segment is on the south side. On the north side there is a steeper section 1.6km long and about 60m high. That section includes another Strava segment with the far less impressive name Dunolly-Avoca Road Climb. I prefer to think of it as The Devil’s Peak North Face. Real hills are a long way away.
So up and down I went. It took seven visits to nail the Strava Climbing Challenge and get my merit badge …
with efforts that looked like this …
As of yesterday 398,811 people had taken the challenge. My position was 82,002nd. The leader is Lukas Rathgeber who had been out 22 times and notched up 79,028m. He’s in Switzerland. He has real mountains and I suspect extremely strong legs.
A recent Strava innovation is an award for the person who has completed the most runs through a segment in the last 90 days. That makes you the local Legend and you get a set of laurels. Given the population density here in the Goldfields it can take as few as one ride through a segment to become a local legend. Modesty almost prevents me from boasting no fewer than 43 sets of laurels. I have completed the Dunolly-Avoca Road Climb 80 times in the last 90 days, most of them in the last 20 – I think I should get freehold title rather than laurels.
Of the dozens of comments that yesterday’s post elicited none make the point better than this one from Roy …
Yes, you must wear a helmet. In a recent bike accident when I hit the back of a 4WD I received a nasty gash around my left eye. My helmeted head put a significant dent in the metal above the tail light. The Emergency Dept staff put it simply. No helmet no Roy!!
The outside world is no place for your brain.
Readers outside Australia may also be wondering why we are attacked by Magpies when they never have that privilege. The answer to that is simple. Our Magpie isn’t really a Magpie at all.
The Australian Magpie (Gymnorhina tibicen) must have reminded the early settlers of their own Magpie which is not a close relative. It does seem a stretch but bear in mind they had been at sea for a long time.
This one is the original. It’s formal name in English is the Eurasian Magpie, scientifically Pica pica.
There are many other examples of birds that migrants have misnamed for similar looking species back home.
Personal protective equipment is big news presently.
Cyclists in Melbourne are presently restricted to an hour’s ride a day and no further than 5km from home. Traffic volumes are down but it seems that some drivers see this as an opportunity to drive faster than usual. Where I live cyclists are not quite so restricted but the roads I ride are open highway – all the traffic is going fast.
It’s worth remembering that Kreisfeld & Harrison 2019 examined the injuries sustained by cyclists and found that about half of those that died did so because of head injuries. So wear that helmet.
Hang on, is that an endorsement? The figures are for Australia. Helmets are compulsory in Australia and compliance is high. Helmets didn’t do a lot for those that died but hey …
there are other good reasons.
Helmets provide excellent protection from Magpie attack. The bird in the video staunchly defends its stretch of road. Where most Magpies are content to swoop without making contact this one routinely hits you in the back of the head. They always attack from behind. I have seen a fox running flat out to escape the attention of a pair of these feisty birds.

To recap very briefly … Old couch potato is enticed onto a bicycle and it reawakens something within that has been dormant for quite a few years and he likes it.
The regime goes something like this …
- cycle 5 days a week – average 250 km/week in recent weeks.
- weight training 2 days a week.
- Diet – low carb high fat (keto) ovo-lacto-vegetarian, lunch and evening meal nuts in between (usually no breakfast). Protein supplementation to reach ~1.5g/kg of ideal weight.
No calories have been counted.
Too many progress reports would become boring but not enough could give the impression that I was trying to conceal a failure.
Initially, as always, the weight simply fell off …I weighed myself the day I bought the first bike. The diet started three weeks later. The dots represent every Monday since. Somehow I always seem to weigh more on Mondays than on other days, how does that work? If I changed days would that phenomenon follow me?
About five weeks ago the weight loss ground to a halt. 13 kg of ugly weight gone – a guillotine could not have done better (average weight of a human head is only 5kg). Along with it went more than four inches from my waist.
A successful diet is one where an overweight person intentionally loses more than 10% of their body weight – 11kg of 93 = 12% – and keeps it off for more than a year. The foundational study by Stunkard and McLaren-Hume 1959 found that of 100 obese individuals only 2 were in fact successful.
So this is the time to ponder a few important questions.
- Why does weight loss stop?
- What can be done to prevent a big bouncing relapse?
It takes a certain amount of food to maintain a particular weight in the presence of a certain amount of exercise. That’s simple enough but how much varies from person to person and even for one person at different weights. So consider firstly the unlikely case of someone eating the same number of Calories and doing exactly the same amount of work every day. Let’s assume that at the outset Calories in is less than Calories out – the stage is set for weight loss.
There are two forms of energy store in the body glycogen and fat. Glycogen is stored in the liver and muscles. It is readily available energy, the first to go on a diet and it takes three times its weight of water with it. That’s the easy part. Once we get onto mobilising fat things slow down.
But progress goes on. As weight is lost the energy cost of the work done decreases and the size of the Calorie deficit decreases with it. Weight loss slows and will eventually stop.
In reality it stops well before the point that simple maths predicts for a number of reasons. Humans have not always existed in a world awash with food. We have evolved mechanisms that help us survive food shortages, endure periods of starvation. The recently emptied fat cells pump out lipoprotein lipase, which tells the brain “hey, we’re starving”. Leptin, the hormone that tells us we have eaten a sufficiency, diminishes. Ghrelin, the hormone that makes your tummy grumble, increases. Peptide tyrosine-tyrosine and cholecystokinine increase. These things conspire to increase your appetite.
Meanwhile the resting metabolic rate goes down in response to reduced thyroid hormone (T3) and reduced activity in the sympathetic nervous system. Levels of a group of proteins that uncouple metabolism from energy production (analogous to wasting petrol by revving the engine with the clutch disengaged) diminish. In the good times some excess energy was simply turned into heat now faced with a famine nothing is being wasted.
Yet more energy can be saved by reducing nonessential activity.
When the recently obese person is compared to a never obese person of the same weight and body composition their energy economy is quite different. All the differences are to the dieters’ disadvantage. Failure beckons and I’ve traveled that route before.
However, only 98% fail.
So far I’ve relied rather heavily on Exercise Physiology for Health, Fitness and Performance by Sharon Plowman and Denise Smith. The next section owes much to a paper by Wing and Phelan which can be found <HERE>.
They paint a picture that is less bleak, as many as 20% manage to keep the weight off, and they present some of the characteristics of those that do identifying six key strategies for long-term success at weight loss …
- engaging in high levels of physical activity;
- eating a diet that is low in calories and fat;
- eating breakfast;
- self-monitoring weight on a regular basis;
- maintaining a consistent eating pattern; and
- catching “slips” before they turn into larger regains.
In addition those who initiated weight loss because of a medical trigger such as a relative having a heart attack were more likely to succeed.
Holidays and weekends are dangerous moments and those that maintain the same regime through these periods as they do the rest of the time do best. Once relapse is underway prospects are poor. Depression bodes ill.
I can put a tick against items 1, 4 and 5. Item 6 is really what item 4 is all about and hasn’t yet been put to the test. My most obvious vulnerability is relying on satiety to determine portion size.
But, oh dear, a low fat diet and eating breakfast are not on the agenda.
I have no doubt that these are common practices in those that succeed in long term weight maintenance but my conjecture is that these have not contributed to their success. Clearly these are remarkably self disciplined people. The discipline they have imposed on themselves is a very orthodox one. Dr John Harvey Kellogg told the world that breakfast is the most important meal of the day to the certain benefit of the food producers but there is no evidence that it is to the benefit of the rest of us. On the other hand there is some evidence in favour of intermittent fasting. I tend not to eat after 9pm and defer breakfast until noon giving my pancreas a 15 hour rest on the majority of days.
Fear of fat is another well entrenched orthodoxy. I’ve lost weight on a high fat diet. It defies logic that I can’t maintain weight on a high fat diet.
These two points are examples of well-person confounders – baggage that is carried along with useful characteristics that really do contribute to health.
Or at least I hope that’s the case!
