With thoughts and efforts focused on the Argus Cycle Tour just 3 days away, it gets easy to forgot about everything else going about around us. The CounterBalance Trust has still been seeing the impact of the Freedom Revolution Unicycle Tour (come on, it’s too early to have forgotten what that was about! One of the organizations that felt inspired by the Tour was CAG.
The Community Action Group (CAG) of Herzlia Middle School in Cape Town does amazing and very diverse work with the goal of helping others. Some of the things they have been involved with include regularly visiting Children’s Homes, Homes for Seniors and Hospitals, arranging a weekly collection of sandwiches for Foodbank (an organization which distributes them to children in need). They also collect tsedekah (charity) for a nominated charity each term. This is where the CounterBalance Trust comes in.
For this school term, CAG has nominated the CounterBalance Trust as their charity to support! And not just by collecting money and handing it over. Margie Cook, in charge of CAG, has planned a barefoot Civvies Day with each pupil contributing R5,00 AND a pair of second hand shoes in good condition. WOW! Not only will this make a dent in our goal of collecting 2000 pairs of shoes for school children in South Africa, but I think Margie has found a way of really bringing the plight of shoeless children to life for the pupils or Herzlia. So easy is it to see pictures of poverty, to imagining the needs of others. But too in some way actually EXPERIENCE it adds a certain reality and remembrance to the issue.
I was invited to speak to the Herzlia Middle School staff and Pupils at their Friday morning assembly before the interhouse Swimming Gala. Armed with a few words and a lot of pictures from the Tour, I was pleasantly surprised at the interest that the learners had in not just the unicycle, but also the goal of the tour. The impact that this had is best conveyed by looking at how well the recent barefoot civvies day was received – almost 300 pairs of shoes were donated by the pupils. THREE HUNDRED PAIRS OF SHOES! That is thirty tens of pairs of shoes! 600 shoes! 6000 toes (give or take a few of course)!
So to Margie Cook and the Herzlia Middle School CAG, the CounterBalance Trust thanks you for your support, generosity, and creativity in spreading the word about our goal to donate 2000 pairs of shoes to your peers. The impact that a pair of shoes has on the lives of those that receive them is more than can be described, and I hope that you all realise what an influence your contribution of “just “ a pair of shoes is making to the growth of South Africa.
"Good advice and other fallacies"
Our wonderful mascot – 'The Shunicycle' was introduced months ago to you. He/she hasn't received proper recognition on our site. Although when out in the field, Shunicycle brought laughter and smiles to many, many faces. Shunicycle is an engineering masterpiece and a piece of art.
Shunicycle's creator, Julian Wills of Novatek is going to give you the low down…
When Alan mentioned that it would be great to somehow combine the Freedom Revolution Unicycle Tour and the school-shoes-for-charity theme, the compelling desire to build something entirely impractical was suddenly totally justifiable – in our minds at least.
The web has a few pictures of similar sneaker-shod unicycles, but little else. Not even a name for the contraption. Hence, the shunicycle was christened; nice to be able to participate in evolving the English language.
Alan sourced an old 26” Koxx frame, complete with hub, cranks and hidden cracks – it had lived life to the full. It arrived in a box together with 4 pairs of size 4 leather school shoes, with 2 weeks to get the job done and back to him before the start of the tour.
The tricky part was to fit the shoes in the frame in such a way that the whole assembly was roughly circular; shoes are actually fairly flat and need to be held in a more curved shape. Each shoe had to be angled slightly to fit between the frame arms and to look more natural (not that a shunicycle could ever look natural) with only a few mm to spare between the shoes and the frame. The layout and drawings were done using a 3d computer draughting system.
Each of the 8 shoes has a laser-cut insert onto which the shoe is attached with pop rivets; the insert was welded to a steel tube which in turn was welded to a new machined hub.
Small man-shaped figures were laser cut and added between the spokes to provide a better stress distribution – with style. It was an interesting exercise designing the shunicycle to be strong enough as cantilever beams (the spokes) are weak for their mass. Contrasting the result with a typical cycle wheel, it is a good reminder of just how effective the structural design of cycle wheels is in terms of maximising strength vs mass.
The shunicycle was painted black to match the frame and the man-shaped cutouts were painted in a fluorescent yellow – to look cool at night and to lessen the likeness to 2 superimposed swastikas. Finally, the shoes themselves were riveted to the sole plates with heels and toes touching.
The post assembly test run involved trying it out in the middle of the night with a bogroll as a seat (thank-you Alan for not sending us a proper seat); in brief, this is not a recommended arrangement.
When the shoes and frame originally arrived and we started making the Shuni, I could see that most employees thought I had lost the plot but remained very polite about it . Once it was complete and I showed them the end result, I could then see that they were no longer in any doubt. However, one has come over to the dark side and is now also a keen municylist.
In terms of ride comfort, handling, power to weight ratio, etc. the Shunicycle handles like…. well… a noisy, heavy octagon with rounded corners. But, what the heck, it is very exclusive and does attract a lot of attention. It also has some other unique features:
• Idling is an unnecessary skill as the Shuni can be kept balanced on any of it’s 8 shoes. It is in fact easier to stay stationary than to move forwards.
• Pumps, punctures and snakebite – forget them. Put a tin of Kiwi in your pack instead.
• A cycle computer is unnecessary; just count the bumps – each bump is 1 foot. You also do not need to be particularly numerate as you won’t be riding very far.
• The Shuni leaves a really mean set of tracks – like a big millipede.
• It makes a noise. You don’t need to put a card in your spokes with a clothes peg; do kids still do that by the way?
• You may ride it without socks.
Now, what if we tried suction cups instead of shoes?
