George, I wasn't aware that all Federal land (BLM?) in Utah was verboten for e bikes? I know there is a list of popular MTB trails around Moab that was discussed last year, including the SlickRock trail which was developed by motorcycles. There is plenty of Federal land that allows motorized use and there should be no problem accessing that, but perhaps I missed something?

The big problem across the pond is that they are stuck with the 250w/25kmh statutes. The extra 4 mph we are allowed here is minor compared to the 750w (1000w) legal status we currently have here. For me the top speed of 20 is not all that restrictive for what I see the need for on an e bike. But the extra wattage and the ability to get to that speed either as quickly as possible or while carrying a heavy load or a combination of the two is huge and a big bonus for us here.
I would never jump through the speed pedelec hoops they describe above but instead just get a moped which would cost a lot less either here or across the pond. Sure they are not great at pedaling or pedal able at all but the concept has been around for ages. Still cheap transport in the end and readily available and understood.
