Yep. I've done an L2e, and some day I will manage an L7e. :)

Interference testing was not needed. The motor wattage and motor controller wattage labels were examined. I could have dropped in more power in a mood for forgery, but I was in an honest mood. :)

Oh wow very nice, congrats!

I want to build a tadpole recumbent / cargo bike for shopping, then maybe a quadricycle and a velomobile with motor for pedelec. I wish they'd allow pedelec up to 50km/h instead of 25 without needed certification and insurance. That'd be a huge boost for the environment. But even the L1e with 45km/h seems purposefully gimped for city traffic to protect car manufacturers.

But a proper "recumbent motorcycle" that can go 100km/h with 3 or 4 wheels and is ultra lightweight would be awesome too.

Myself, I went for 45 km/h officially (unoffially, on a flat road, I could reach 53 km/h). While turning, for safety reasons, I limited myself to far lower speeds (25 km/h).

Designing a car suspension system for reasonably high speed seems hard, I have never tried, instead choosing the robust and crude solutions to get a reasonable assurance of strength.

Motorcycles seem easier. Especially since most of factory-made motorcycles use a sprocket and chain - a very flexible system for dropping in other power sources. I imagine that with enough know-how to get through type certification, a lot of combustion bikes could become e-bikes with excellent riding characteristics. :)
