"One that looked interesting is a Giant Roam E+ GTS ... I have no idea what the difference is between them..."
For the Giant Roam E+ GTS the only difference between these two models is just the frames: the one with the higher top tube has what is called a “step over” frame, the frame with the lower sloped top tube is called “step thru.”
Everything else for both of these two is the same. Both are Class 1, 20mph assist cutoff and without a throttle. Both with aluminum frames, Yamaha motor with Garvin controller, moderate Shimano Altus/Alivio 1x9 shifting, good Tektro hydraulic brakes. The Energypak battery is Giant proprietary China-made orTaiwanese – a spare would be about as expensive as Yamaha or Bosch batteries. Hopefully the Suntour fork has travel lock-out, 63mm is not enough suspension travel to help out. Neither has headlight, tailight or horn.
Keep in mind that for a throttle-less ebike all you have to do is keep spinning the crank to keep the motor engaged – you don’t have to work a lot at pedaling. As said, your wife should test ride an ebike before buying.
Downside with a lot of ebikes, like these two, is a flat black or satin black paint job – black doesn’t help with conspicuity.
