Sorry but your bike has some very significant differences. The front wheel is much further back. This makes the wheelbase too short, and puts too much load on that small front wheel. If you get a chance, ride a modern medium wheelbase bike like the Bachetta, RANS, Volae, etc. You will be amazed at the difference.
Warren, the numbers do not support your contention. On the Bachetta Giro 20, the wheelbase is 47", per:

The precisely measured wheelbase, axle-to-axle, on my Bachetta clone is 46.5".
Below is a photo of the Bachetta Giro 20 I pulled off Google:
The image of the bike from the Bachetta website even shows the same brand of brakes, wheels and tires. The only differences I can see are in the seat and seat stays, driveline components and the handlebar assembly and the fact that the boom on my bike is adjustable, while on the Bachetta, it is not. My bike is over 5 years old and I'm comparing it to an image off the Bachetta website of a 2012 Giro 20. (In the image I have in this posting, that bike has disc brakes. The stock Giro 20 has V-brakes that are identical to mine.)
I do not mean to diminish the quality and value of the Bachetta Giro 20, which is off topic of this forum post. This thread is, if nothing, a tribute to the comfort and capability of the design. The most important point I'm making in this thread that my research has (sadly) revealed: a SWB recumbent with a 20" front wheel is too dangerous to mod into an ebike that runs at 30mph. I do not recommend this be done by anyone else in these forums and I plan to remove the components from this bicycle and put them on something else. I am in mourning about this and trying to get used to the idea of giving up this bike for commuting, because this recumbent is a thing of beauty: I biked 31 miles on it in jeans and street clothes in complete and absolute comfort. But I just can't recommend anyone else do this ebike conversion for safety reasons.
