[trikes] hubless wheel trike

[Philip Donahue]

Well, my Trice XL and Explorer only have ground clearances of 8.2cm and 17.8cm respectively, so I imagine 20cm puddles could get uncomfortable.

As we know from our low trikes the chain down close to the ground is not that big a deal, just not that close.  Nothing says you have to use rimless on the back if you have them on the front.
