Is it possible to convert an 8 speed 11-32T to 10-32T?

the joy of small wheels and a mid -drive

I'm now glad that I couldn't source a 20" hub drive at the time I had to buy a kit pre-Brexit - there's no way that a legal hub could do what my bike is being used for at the moment. The bbs01b really is quite brilliant. Even at just 15A. And quite literally a joy to ride, although of course limited in unassisted top speed by the bike's gearing.

...the box could be made pretty darn tall, capable of carrying very heavy cargo. I recall you found the weight limit of your Carry Freedom Large Y trailer some months ago, while too many carying compost bags, but can't remember at what point your CF's axles worried you.

One reason why opted to replace the bed with longer one to carry boxes in tandem, too tall and trailer stability was potentially an issue over uneven terrain or even pot holes.

1m sides would be too high, if fully loaded with heavy weight all the way to the brim. This box could be as wide as the platform, depending on how cargo was distributed, the center of gravity could be lower. 2X 43cm high 25kg water bottles doesn't make the Homcom feel too unbalanced, but then there are 22 X 2.26kg plastic milk bottles filled with water with a low center of gravity, around them. I'm a trailer newbie, you've got more experience - about 60cm? That could allow space at the top for light items like duvets for the newly homeless etc, should one feel generous toward those poor souls who can't afford their mortgages, rent, energy bills or food this winter. Or sleeping bags and loaves of bread topping off stacks of bake bean tins, camping stove, gas bottles etc. for bike trailer camping holidays in Bulgaria. Or compressible padding to keep honey jars from bumbling about in transit, or something.

Yes, the max I carry is approx. 60cm above the trailer bed with heavy loads.
Low CofG is as you say best for stability.

When I first bought the CF I tried with a single stack of approx. 1m high and though no accidents, realised it was not going to be very stable for my use. One reason why I modded the base for a tandem layout.

CofG isn't a difficult calculation (especially for boxes). The proposed built box would be wider and longer, and if carrying the same weight distributed evenly, it's CofG would be lower... therefore the built box could be made a little higher than 60cm, to match the currently manageable CofG of your existing boxes? If we know the dimensions of your boxes you normally use, we could work it out.

My boxes are 462mm square and either 152mm or 225mm high.
Six of the smaller ones are about the most I carry with combs fully filled with honey as it equates to some 240lbs in weight, each box weighing some 40 odd lbs.
The larger boxes are about 65lbs each if filled.

 

[guerney]

The max load bed size/proposed box base size according to CF is L 900 x W 640 mm - so compartments within the box then for your combs? Two small boxes with bases arranged lengthways W 462mm X L 462mm = 952mm, too long for the load bed. What length, width and height are your combs?

I've forgotten the dimensions of the larger platform you made for your CF. Do you have two box configurations: one with six boxes which fits the platform in one layer, and a second configuration comprised of a layer of six of the larger boxes? If both configurations fit as single layers, a custom bee box isn't actually needed.

If you made a custom bee box to fit your bespoke platform exactly, could you fit more combs into it as one layer, if you used rails (or something) to hold the combs? Mind you, you'd have to remove the combs from the one big bee box, once you got them to their destination, and you wouldn't be able to lift them all out at once - you'd need them in custom sub-boxes to make that process manageable (which is the solution you have now of course). And carrying many more combs at once might be too heavy? How much does a comb weigh? Must say I know nothing about how combs are held in place witin hives.

 

[Nealh]

I don't need any custom storage or tranportation needs, the boxes I use are ideal and a UK std size for the hive footprint I use and the CF bed I made is ideal for my boxes in tandem.

The Homcom's cargo cage sides are overengineered. Nothing short of a 50kg cannon ball rolling around is likely to damage it. The plastic platform material would fail carrying cannon balls far lighter than that (ie too much weight iin a small area). I might build a big box for the CF sometime.

The large chain ring and 11t on the back increases the chain load, if you try and apply full power in the 11t from a lower speed it can snap the chain .
