Any plans to sell a spare parts kit? While transporting mine and my wife's trikes last night, the bolt that attaches the seat riser to the frame must have vibrated loose on her Rover. Fortunately I had a zip tie in the car that I was able to use as a temporary replacement. The whole ordeal has me thinking about putting together a small parts toolbox with extra nuts, bolts, seat pins... It would be great if the terratrike folks sold such a thing instead of me having to try to find each piece and paying non-bulk rates for them. Just a suggestion.
