I have a long wheel base recumbant with a Robin Subaru 1.6 hp engine. If you need to cover a longer distance it can't be beat. It will surely put miles behind you much faster than a electric. The range is much longer also. I don't get a very relazing ride with it. The vibration and noise deminish the enjoyment signaficantly. This coming spring I am going to build a Rans Stratus with electric. I believe for shorter rides the electric will fix the rattled effect I get from the gas engine.
