Drew Buck did PBP on a bike which back pedalled for one of its two gears.

The 'Ladep Tallbike' (pronounced "Pedal-backwards Tallbike"  ::-)) was a pedal backwards bike:

https://www.youtube.com/watch?v=BHOGzk3Sgbs

(That is Arch's voice you can hear as it was she who filmed)

The one in the video ham posted seems to have an eccentric front wheel and, by the looks of it, reverse steering.  :o

I built an eccentric front wheel for our 'PoGoPed' that could be powered by bouncing up & down once you got the hang of it (a bit like learning to power a swing)...



...and we have built a reverse steer bike. I've only got video of me learning to ride it:

https://www.youtube.com/watch?v=FEHY4q4oPkY

I have mastered it now as those that have seen me on it at Mildenhall can testify.  :smug:

The one in the video would be very difficult to learn to ride, as is our 'Ekib' (pronounced "Backwards bike"  ::-)), which is I suppose a reverse pedalling bike of sorts.  :demon:



BTW, I'm going that-a-way on it ---------->

Groan...

It's ages since I made any progress on the Wobbly Workshop projects.  :facepalm:

I been having a big clear up at home and have just taken the useful bits off an old project bfore dumping the rest of it.  :(

So, I thought I'd repost the write-up I did on another forum when I built it - in the days when ACF ended and YACF started.

First installment:

Starting off with a scrap exercise bike...



... and welding in a bottom bracket shell and some forks



Then I made a mounting for a 12V electric motor. The motor has a knurled aluminium roller on it as it was used in a Robot Wars type thing, driving a wheel by friction.



The electric motor was then mounted so that it would rest on a wheel held in the forks





I now need to find a bottom bracket, chainset and chain from the pile of dead bikes.  ::-)



So what's it going to be?

1. An exercise bike for lazy people   ;D
2. A training aid for increasing the cadence of fixie riders for faster downhills   :demon:
3. Other - suggestions please

Generator?

Be a good teaching aid for kids if so.

Could be reversing the Obree process and building a washing machine using cycle bearings, I suppose.

Second Installment - Todays report will be brought to you via the medium of Lolcats:D

This may be something to do with yesterdays project.
First I need a bucket...



...and I need to drill some big holes in it.



A strong elastic band for it is cut from a car inner tube.



Now for the 'guts' of the thing, a computer fan is fixed to a base...



...and once a guard is fitted, this sits in the bucket.


Couldn't think of a caption for that one

Okay...

So what is it going to be?

Unfortunately the fan wasn't good enough to inflate the survival bag sized EvilChuffy/demon smiley we made:

A work collegue had been clearing out her garage. Her husband used to work in the computer industry.

"Can you make use of some 12V fans?" she asked.  ::-)

I now have a crate of brand new 5" fans to play with.   :thumbsup:

Do you think a box of a dozen will inflate the EvilChuffyFlate-abubble?   :demon:

Wellllllllllllll...

Generator couldn't produce enough current for the 12 fan two stage mega blower  :(

Plus a square box is not good for fixing the bag to.   :facepalm:

I'm going to try the bukit again with some more efficient fans:

65 watts of of fans in two stages have been replaced by 18 watts of centrifugal fans (in a bukit)



And the result...

Folk should be aware that Wobbly John was seen at Mildenhall with a couple of turbo trainers, a few other components, and the glint of inspiration in his eye.

FTFY.

He could be halfway around the world on a bicycle-powered zeppelin by now.

Two broken (the plastic fans were borked) turbo trainers for a fiver - just what I was looking for.  :demon:

You might also see the tandem stoker handlebars (like on Wowbagger's tandem), that I bought for a £5, on this thread too.  :smug:

...but I didn't manage to buy enough 'Space blankets' to make one of these:

Why do I keep imagining your neighbours peering from behind their bedroom curtains whispering, "What the **** is he doing now?"

Yeah, I know. Sorry, folks :(

My colleage in the workshop at work had major, open heart surgery about a month ago, so things have been rather busy at work (he's recovering well, but will be off for some time).  :-[

At home, my son has moved back in to 'Wobbly towers', so we have had to clear enough space for him, his dog, and the contents of his house.  :facepalm:   My daughter is due to move house in a weeks time, and it will be down to me to decorate inside and out over the winter & spring. (this will be the third house I have decorated for her in 6 years).  >:(

Hopefully 'normal' service will return. I'll probably post some minor projects (some 'work' ones) as I get the opportunity.
