Great idea on the seat cushion. I'm finding the cruzbike stock material a bit squishy and was wondering what else I could use. I was thinking about butchering an old camping mat i have

Ventisit.  I mean, closed-cell foam is lovely when it's  a) cold  and  b) pish[1], and it's easy to work with as a way of contouring the seat underneath the pad (I've got a bit of old camping mat doing just that), but the rest of the time something that allows a modicum of air circulation is so much better if you're going to be riding for more than a couple of hours.  Ventisit is also firmer and more breathable than the pond filter stuff.


[1] It's lovely when it's cold and dry too, until you get off the bike with your soaking wet back and promptly develop hypothermia.

I'm not so fussed about the wet back, more the compressibility of the stock foam combined with the width of the seat results in an edge right inside my shoulder blades at the top of the seat. Was thinking of a couple of layers of camping mat under the stock foam, which does seem to move the moisture away reasonably. 

I had a ventisit on my ICE B2 and was happy enough with it, and looking at pricescfor direct purchases they are not unreasonably priced, so I may try the camping mat first followed by the ventisif if unsuccessful.

Grandson sitting today, so unable to get much done.

I did a bit of flagmaking  (Mrs WJ sewed for me):



And some routing on the seat pad:



Made a bit of a mess of it in places - it only takes a little knock or slip to go off-line.  :-\

Hoping to go for a ride tomorrow...  ;)

The machined seat pad fits the seat better, and is more comfortable.



 15ish mile ride into Ely today, and the first person I bump into, at the coffee stall, is Hugh, who did the aluminium welding for me.  :D

I've been doing little bits at work, using a couple of old tent poles, and a couple of feet of aluminium extrusion from an old whiteboard frame - nothing worth taking photos of...

...and cutting another bit of scrap stainless steel...



...to make this mount:

One problem with the Windcheetah is carrying stuff - a few tools, tubes, phone, wallet, etc.

So, I've made myself a rack:



It's not as elegant as I would have liked...



...but holds the rack-pack in place.



I took a couple of house bricks for a ride around the block to test it out.  ;D



The Yellow bottle cage arrived too.  :thumbsup:

Love the colour-coordinated bottle cage.   :thumbsup:

Put the rack bag on the other way round, though, that wedge shape looks aerodynamically embarrassing.   :hand:

I'm impressed (and slightly mystified!) by the lack of twist in that rack when it's loaded.  An impressively neat and simple solution!  :thumbsup:

And +1 on the bottle cage.

Brilliant!  I assume those are temporary cable ties, until the yellow ones arrive?  ;)

I have yellow ones somewhere - just can't find them in the workshop.  :P

So when do you re-start Speedy production using 3d printed lugs? I know the man who used to machine the castings for the last guy...

Before that last picture finished loading, I said to myself 'I bet he's 3D printed that'.
Nobody other than Fisher Price, injection moulds anything in that colour  ;)

Do you need a barrier between bag and wheel Wobbly?

Redshift OTP used to use something similar. When the pack started to sag and occasionally catch the tyre she did surgery on the LH pocket - a radical pocketectomy.

TBH, I'd say the whole back wheel needs enclosing.  Mr Burrows would probably suggest a haircut.

Must be this brower (Puffin).  It's done the photo-substitution thing again, so what shows up as a yellow bottle cage elsewhere is appearing as author Marshall Karp standing on a New York street corner ???

Grandson James now has a recumbent trike too!

This evening we tried fixing up the old, ex-Cyclemagic KMX Kart that has been in the workshop for 5 years waiting for him to grow big enough to ride it.



He had a few rides up & down the road, but then one of the chain tubes came loose.  >:(
One of the tyres is tearing as well, and the chainring discs are loose, so I have a bit of work before he can have another go.  ::-)


He tried the Wincheetah for size  - a long way to grow, yet.  ;D
Younger brother Elliott will fit the KMX sooner:

Yeah.  Less scope for putting your shoulders on the bum-end of the seat and arching your back over the steering pivot to reach the pedals[1] with a tiller.


[1] Technique successfully (if somewhat improbably) employed by EldestCub[2] a few years ago to pedal my Streetmachine a good 100m or so when he was still blatantly too small for it[3].
[2] Not to be outdone, SmallestCub photobombed a local BBC TV news interview using a similar technique on barakta's ICE trike.
[3] "You can't reach the pedals, but I'll push you up to speed and we can see if you can balance it."

How old, and what are those things like to ride? My 8yo has been casting envious looks at my trike (though she might be big enough to ride it by the time I finish it!).

The KMX Kart suits from about 7 year old until they are tooo tall (small adults) They aren't the best, quality wise, but good for their intended use of having fun on and off-road. Of course, they do tend to get more abuse than other recumbent trikes.

I've seen them sold for around £100 new, and that's about what they often make secondhand too.

The one I have was used at Cyclemagic tryout roadshows etc, and was sold off when they disbanded.
