I had a friend who got one of the cheaper three wheelers on the market, apparently the thing was very unstable going into corners (and hence VERY slow) - worthwhile considering. I also knew someone with a Christiana - and I regularly see one in Parkside, and those things look absolutely bomb-proof (hence the price I guess!!)
I have one of these http://www.cargocycles.com.au/ it is on semi-permanent loan to a friend currently though I have people test ride it. I sold probably the majority of these in Adelaide in conjunction with Clarks Cycles on Magill Road. Unfortunately the quality control on these Chinese manufactured bicycles is a bit disappointing. That said, they are not a Bakfiets http://www.bakfiets.nl/eng/ , merely a good, cheap, copy!
That said, I really love mine, it is fast, stable, good gears and will haul a HUGE load - also the stand is a 4-point platform and works really well - there are a few issues, but nothing that can not be fixed - again- quality control....
The Cabby that was at Bernie Jones Cycles was on consignment and is now on display at Clarks along with other Gazelle bikes - I took a few photos of theme here
Are you saying the cargocycles.com.au ones are unstable, or was it another brand?
I'm a little concerned about the quality of manufacture, but I'm pretty handy with a welder should anything fail. The downside I see is that it is only a three-speed. I'm happy with my single-speed bike when it's just me and my boy on the back, but if I'm going to haul around 50kg, I think a few gears could be handy. :)
Not sure, I think that it was one of these http://www.cargobikes.com.au/ but honestly I am not sure so I will reserve any judgment! The two wheeler that I have comes with an 8 speed hub - this seems quite adequate!
Oh. Sorry - getting my bikes and cycles confused. CargoBikes.com.au have released a new model, so I'm hoping they have sorted out the stability. I'll give one a test-ride first...will take it through some corners. :)
I've had no luck at all with cargobikes.com.au. I spoke to them on the phone a couple of times but didn't get back to me about checking one out here in Adelaide (apparently there's one in Stirling that you can test-ride). I've given up and it's, unfortunately, dropped down the list of priorities.
Am going to speak to a couple of friends in Sweden to see if they can't ship me a Christiania Bike.
Three wheeler will be more stable when stopped and when moving at very low speeds (walking pace).
But if you want to commute on the thing, I would seriously consider a good two wheeler (like an Xtracycle similar to what Jeremy and I have) with a really serious kick stand. I don't think that you'd miss low-speed or stationary stability that much. But lifting your three wheeler over the eighty-fifth curb because you can't hop it will annoy you.
