Don't see why not.
I had a Catrike Expedition for a little over three years, fully fitted with a full set of panniers, fantastic in all weathers, done about 22000 miles with a mixture of commuting, actual bike rides and pottering about. In that time (apart from tyres) the only thing that needed replacing was the chain, cassette and a frayed brake cable. Don't know if I'd want one now living in London as I don't think it would suit the commute but if I was out in the sticks I'd give it some thought.
