Fed Square this Saturday

Hi

This Saturday (December 11) I will be at Federation Square selling my bike books and cycling boardgame from 11 - 5. Last chance before Christmas to buy them, after Saturday I hang up my booksellers hat and start doing things appropriate for the season - finishing off the year at work and going surfing! A few of my friends are having a 50th birthday bash at Phillip Island and my family will be down there with bells on.

Anki Toner has listed my cycling boardgame on his cycling boardgames website, see http://www.cyclingboardgames.net/g_cycletour.htm

He likes the chance card "Schoolkids yell get a real bike, move back 1" but what about the shopping tokens "Kamahl's Greatest Hits, $0" or "The Adventures of Barry Mckenzie Movie on VHS Cassette, 50c." C'mon Anki, lift your game.

Ok, might see you Saturday

Best Wishes

An Inner Trailer

Hi


For a while now I've been mucking around with bike trailers and recently built one for carrying a large amount of shopping behind a folding bike. Unfortunately this trailer didn't fit on my recumbent and I wanted a trailer for my recumbent so you guessed it, the shopping trailer was due for the chop or rather "annihilation by jigsaw". And rather than building an ordinary trailer, how about one that trails from the front wheel of my bike? (My bike is well-qualified for this type of trailer, being long wheelbase, front wheel drive and having a really big space between the 2 wheels, more about it here:
http://www.modularbikes.com.au/bigatthefront.html)

So I began work. The trailer has a height limit - it will bang into the bike frame if its too high. Keeping this in mind, I mounted the trailer wheels on the back of the trailer box so the bottom of the trailer could be kept low allowing for reasonable depth. The box is made from unbraced plywood and is therefore a bit wonky and I will see about improvements at a later stage. The drawbar is a 28mm garden stake and it's attached diagonally on the base of the trailer.

Initially I thought I could just drill a hole in the drawbar and hang the trailer on a pin mounted on the front fork. I made the bracket on the bike, but when the trailer was hitched up it was too high and I couldn't pedal. Back to the drawing board.

Next step was to cut a small extra piece of garden stake and sandwich part of an old bike tyre between the drawbar and the new piece of wood. Apart from anything else, the extra bit of wood helps push the drawbar away from the wheel so the wheel doesn't bang into the drawbar during turns. The tyre was looped at the top and the loop was secured with a few screws, nuts and washers.

Then it was time for a few blockies to sort out any problems. The low ground clearance led to, you guessed it, scraping of the trailer base on the ground and I did a bit of work to fix that. My son Ewan took the main photo the next day when I was on my way to sell books at a book market. Trailer still way too low and lots of scraping, so en route I stopped and twisted the tyre which the front of the trailer hangs from to bring the drawbar up a bit. And this worked, I arrived, bike, self and cargo and trailer intact at the book market.

While at the bookmarket, I readjusted the loop at the front of the trailer and the whole thing worked very well on the way home.

Well what I have here is certainly exotic - an exotic trailer on an exotic bike. Here are some of the advantages and disadvantages of the design.

* Wheels on the trailer are at the back. When compare to a 2 wheel trailer with wheels in the centre, the trailer hitch bears weight and the drawbar must stand more bending force. The bike is front wheel drive so weight on the front wheel is a good thing - there was no wheel slippage when climbing hills.
* This bike plus trailer is much shorter than the standard trailer arrangement. As well, the trailer following behind is very low and would probably need a flag for it to be seen by drivers peering over car bonnets. With the trailer in the centre, a flag is not needed.
* Having the trailer in the middle restricts the height and length of the trailer. Extra volume can be achieved by having a wide trailer, but this starts to make getting on and off the bike difficult.
* Once in motion, the bike and trailer handled ok. But starting was a bit harder than normal, I had to sit on the bike and start pedalling from a standstill. Normally I can start walking or running, then leap onto the bike side saddle and get going that way.

* The current trailer hitch allows the trailer front to "pendulum" about the hitch on the front. There is little resistance to motion from the trailer wheels at the back, so the whole trailer can move back and forth relative to the bike during acceleration / braking creating a not unpleasant "trailer surge" phenomenon.

* Not for the shy and retiring!

* Here is the video!

Hi

Over the last few months, Jim Wilson from bikerodnkustom
http://bikerodnkustom4.homestead.com/cover9_03.html has been interviewing me by
email. It was a bit of a stop-start process and we rambled over a range of
topics. So here it is, the interview is sticking out like bits of a dogs
anatomy amidst all the chopper bikes.
http://bikerodnkustom4.homestead.com/nurse_interview.html .

As well as this I have 2 entries in the Melbourne bikefest design competition
http://www.melbournebikefest.com.au/better-by-bike
which will be judged shortly. The Rotovelo from Trisled is one of the other
entries. Another designer (Mark Watson who designed the Tote trailer) has
already been in touch with me.

Game Over

Hi

After about six weeks of after hours work I'm close to finishing the cycling boardgame I started talking about in this post: http://modularbikes.blogspot.com/2010_08_01_archive.html

The game has taken a radical departure from the original (series of races) idea. Hopefully that departure is all for the better. The game is not quite finished but is still very playable. The unfinished bit is that the player pieces are not fully coloured in. (I have almost finished doing 1 and even that took a long time!) But you can do the colouring in. To date I have played the game with my wife, my son and with my friend Tony and his 2 young kids. The game cards are based very loosely on items I have purchased or events that have happened while riding a bike. Hope you enjoy it. Hope you can understand the rules!

Today I updated the game, all the players are fully colored in now and I did some minor changes to the "shopping cards".

A Big Swell!

Hi

Although I've only written about bicycling - related stuff in this blog in the past, I have another
hobby - surfing - which I've been doing since I was about 15. As a Melbourne resident, going
surfing involves travelling at least 100k and often spending time away from my family: so I
don't do it that often. But occasionally I get motivated enough or sick of things enough to run away and go surfing for a day or two. Very fortunately I have access to a place to stay at Airey's
Inlet which is on the coast west of Melbourne. Even more more fortunately, some of the challenging surf breaks around Airey's are not overpopulated by surfers so as a not - very - competitive or aggressive older surfer, I can still go out surfing and enjoy myself.

Before the advent of the internet, knowing what sort of swell would occur on a given day in the future was a black art. You could make some educated guesses and work out what the wind direction would be from the weather maps but what sort of waves would arrive was unknown. Now, various websites predict the surf size around Australia and the world. The one I use most is www.swellnet.com.au backed up by the venerable bureau of meteorology, www.bom.gov.au.
Type "wave" into the bom website and you are a few clicks away from a map like the one shownsomewhere on this blog page. The red and purple bits of the map are areas of the ocean are areas of big waves and when they get somewhere near your bit of coastline there will be big waves. Simple huh? The fact that predictive maps (a few days in advance of now) are available means keen surfers can go to where the big waves will be, virtually anywhere in the world.

But just big waves ain't enough, to get good waves, other things like local winds need to be right.

So anyway, I'll cut the surf lesson short here. Early last week it looked like a ripper swell was developing so I put in for leave on Friday and headed off on Thursday night to see what surf I could find.

Well it was a big swell and on Friday I only surfed at the very sheltered Lorne Point. I didn't see anyone out at open ocean beaches although one guy had been out at Cathedral Rock. Today (Saturday) I went out at a local Airey's beach. 3 waves only, I was out by myself and respectful of the size of the surf. Hope you enjoy the photos.

Note on surfboard: It was a windsurfer in a previous life. It is a long (8"5" in the old currency), sleek, thick and well worn single fin. Very caveman. I love it. Shaped by Howard Hughes, see
http://www.surfcraft.com.au/ Now retired, Howard has been a friend for years and for ages I have ridden on his boards.

OzHpv Challenge: The Board Game

Hi

Well I won't start on the topic, rather just write a bit of a catch-up and then launch into it.

First of all I've been a bit busy! My wife Christine is recovering from an operation and I've been to and from dentists and endodontists this week dealing with an abcess on the gum. That doesn't mean I haven't done things related to bikes, its just I haven't written about them yet.

For a while I've been helping my workmate Brad Jarvis build a trike (donating materials and advice). He's finished now and posted a bit about it on his web blog at http://emotorcycle.blogspot.com/ . Brad has helped me a lot, dragging this website from a small collection of stuff that I've written to something a bit more focussed and impressive. Thanks again Brad!

Well, back to the board game. I read a few Human Powered Vehicle websites quite regularly, among them
Velovision: http://www.velovision.co.uk/
Bentrideronline: http://www.bentrideronline.com/ and more recently
The Recumbent Journal: http://www.recumbentjournal.com/

Velovision posted a link to this wonderful site about Cycling Board Games.
http://www.cyclingboardgames.net/index.htm . It's not a type of game that's known about let alone used in Australia but this website lists hundreds of them, mainly European I think.

I stumbled across one Australian game on the site: http://www.cyclingboardgames.net/g_national.htm

There is a page about making your own board game, and more trivia than you would care to imagine.

Anyway, this got me to thinking: how about a boardgame based on the Ozhpv Challenge? This set of races has been held over about 10 years at Canberra, Broadford, Werribee and more recently Albury. The website for the Challenge is here http://ozhpv.org.au/events/challenge.html

Anyway I've started a small spreadsheet which sets up a premise for a game based on the challenge. It's here http://modularbikes.com.au/game/Boardgame.xls.

Basically the game would have 6 races and six different vehicles, all familiar to Challenge Entrants
Road Race
Off Road
Shopping Race
Slalom
Hill Climb
Time Trial

Road Bike
Mountain Bike
Lowracer Recumbent
Recumbent Trike
LWB Recumbent
Velomobile

Riders would progress a token across a board based on a roll of the dice. There might be 40 squares to progress through in a race.

There's a table in the spreadsheet with something like the most likely outcomes for the races given riders of equal ability, and the idea of the game is to simulate that likely outcome in each race using a set of "rigged dice" (see http://en.wikipedia.org/wiki/Dice#Cheat_dice) The "average" roll of dice will lead to the expected result. Each vehicle has its good and bad races and it all averages out even in the end.

Of course nothing like this happens in the real version of the Challenge. The actual result in recent years has been:

* Someone comes along with a mountain bike and wins the Off Road (Tim Marquardt in recent years)

* Jamie Friday wins everything else and is once again crowned OzHpv Champion!

Some Folding Bikes

After a brief absence, we have a couple of folding bikes in the yard again. Two bikes came up in one lot on ebay, I put in a bid and there you go, a couple of days later I am driving down the Eastlink freeway after work to pick up the bikes in Carrum Downs. I didn't really know what I was getting but they were cheap enough and these types of bikes are easy enough to fix.

Anyway after unloading the bikes at home I got a chance to look at the bikes: I've got a 16 inch National folding bike with rusty wheels and a 3 speed hub and back pedal brake, and a 20 inch "Another Rob's bike from Blackburn" that was probably made in Eastern Europe.

Well I quite like old folding bikes! There is a great German website devoted to them, http://klapprad.de/ which has the philosophy (even if they don't say it!) "These bikes might be old, they might be simple, they might be crappy. But we love them!"

Klapprad is a German term for folding bikes which describes the sort of bikes I like. The German Wikepedia entry http://de.wikipedia.org/wiki/Faltrad mentions the term as follows:

"The need for the term "folding bike" instead of Klapprad came from the need for sellers of high value bikes to distance themselves from the 1960’s and 1970’s Klapprad bikes which were often bad to ride and unmanageable. In contrast, modern folding bikes can ride like full size touring- and sport- bikes."

So, back to my bikes. I did some work on them in the kitchen on Friday night and took the photos, then on Saturday morning worked on the 20" Rob's. This bike has alloy wheels, front brake and coaster brake, worn whitewall tyres.

Try pumping tyres (woods valves) 1 ok, the other has problems.

2nd tyre remove valve, clean valve, replace rubber tube around valve, pump up tyre, ok now.

Remove chain, replace with new one from shed, oil wheel bearings.

Tilt handlebars forward.

Replace front brake cable, oil front brake.

Bike is still rusty. The paint that's left is very faded.

Take bike to front of house, ride to op shop.

Old, possibly homeless guy outside op-shop says that the bike is very old, possibly an antique.

"Yeah, like me", I say, riding off.

Then I started on the 16" National. The wheel nuts are really rusty and I have to work hard to get the wheels off. The bike has a nice, 2 pronged stand and the aluminium mudguards and chainguard and frame are generally in good nick. Despite near frozenness due to lack of oil and rust, the rear hub is a 3 speed planetary gearbox and back pedal brake. Jamie Friday used one of these on his load trike, so its worth using on another bike if not on this one.

1 tyre holds air, the valve and tube is stuffed on the other one.

Removed wheels with difficulty.

Dug out a set of 16" wheels and a tube. These wheels are in reasonable condition, rear wheel has back pedal brake.

Move tyres and tubes to "new" wheels.

That's all sofar, I'll try to get it on the road tomorrow.

Sunday morning was spent getting the orange bike on the road.

Front forks bolt slots too narrow for new wheel. Used electric drill to make extra width.

Seat too low even with the seat post at the top, reverse clamp under seat to raise it slightly, might need to make a new seatpost.

Swap cog on new wheel, I put on a smaller one from the shed which raises the gear inches a bit, also swapping the side the dishing the cog was on made the chain allignment a bit better.

Ok, time for a blocky! Had to fight off my wife Christine and our 98 year old neighbour Edith, they were just itching to have a go on it as you can see from the photo.

The seat is still a bit low but it goes ok. The gear inches are a little bit low and I am pedalling quite fast to get a reasonable speed on a flat road. There is a nice, small organised ride tomorrow, I plan to take this orange bike and see how I go.

14/6/10

Late last night I brazed a couple of seatposts together to make one long seatpost and fitted it to the orange bike.

This morning I headed off on the bike and met Alan & Diane Ball and George Durbridge for the start of the "Bonus VicHpv ride". The little bike performed well all day but the very long seatpost puts my weight right to the back of the bike and there is a tendency for the bike to do wheelies when you don't really want it to. That can be countered: you just need to lean forward when going over small rises or up hills.

The ride itself was billed as follows:

"We will be touring most art on the "Docklands Art Journey" leaflet but in a better riding order, omitting some, and seeing some interesting extras. For some info, click on the Docklands Art Journey link on:http://www.vicurban.com/cs/Satellite?c=VPage&cid=1182927627029&pagename=Docklands%2FLayout Lunch at Docklands. After lunch we start back along the Yarra diverting briefly to view the controversial Yellow Peril now in a more appropriate setting."

The day went very well with Alan wearing his tour leader hat and reading from a printout of a website to describe the varoius artworks we visited. Doing this tour is well worth the effort if you get a chance. Seeing the "Vault" statue next to the Australian Centre for Contemporary Art was a highlight: a controversial statue and Melbourne icon next to a truly ugly building! Thanks Alan!

(See http://en.wikipedia.org/wiki/Vault_(sculpture) and http://en.wikipedia.org/wiki/Australian_Centre_for_Contemporary_Art

All for now and for this post
