Cass - A hearty welcome to Trike Talk! You will not regret your decision to trike your bike. I know that Australia has weight limits for trikes and I think that may be a factor on choosing a kit. I am sure some of our Australian members will chime in on this. The towing capacity of a bike that is triked is still the same as before, plus you have to add the weight of the kit. There are people here a lot more knowledgeable than I that will help. Keep us posted on your progress.
