Good insights given the updated state of things shown in the linked product info.
Back about 12 years ago when I bought my LA Bicycle e-bike, the best option was 24" wheels, 24V and 250 watt motor, and a step through (girl's) frame. It was well designed and well built and I was very pleased with it. But it's not the configuration I'd choose today. (I'd like 27.5 or 29" wheels, 500 watts and a stiffer MTB frame.)
If that was still the state of things, I'd be looking for a kit (and someone to do the hard work) Looks like I can get exactly what I want now at BKKBike, though I'm still commuting monthly and have no place to store it between trips. When I am ready to pull the trigger, I'll also look at the current LA Bicycle offerings because they made a good product for that period.
Thank you both for the great info!
