Magic gears and half links will work. If you have the money, buy one of these-
It's a tandem eccentric for bottom brackets on tandem bikes. It uses a euro BB so higher quality, better parts can be used too. It has an offset in it. It fits into any American bottom bracket shell. Say goodbye to one piece and BMX cranks!
So you tension your engine chain with the wheel, then tension your pedal chain with the bottom bracket eccentric. The eccentrics are held in place using a wedge system similar to a stem. The eccentric costs about $35 give or take.
(I don't know if this is a known part, but most of the people I know with gas bikes have no idea this even exists)
