My wife & I have been cycling together since we met back in 2003.
Regular bicycles at first, then recumbents, then road bikes, nowadays ebike & etrike.
Wife is 4' 11", not particularly easy to find bikes that can fit her and make her feel secure enough to operate with confidence.
For ebikes, wife started with something small & easy to handle, 16" wheels, 6-speed, 350w motor, 15 mph top speed, 35 lb. micro ebike.
Wife wanted something even smaller, so we try a 12" wheel, shaft-drive ebike/escoter, no gears, pedal/cranks just act as a crank generator to charge the large (25Ah) battery.
Once she got a few hundred miles on it, she felt good enough to try something bigger, Lectric 2.0 StepThru;
but somehow didn't like the way it rides.
I bought a Fiido T1 for myself back in 2021, I ride it few times a week carrying large volume of items between places.
Wife sees how much I abuse the Fiido T1 and thinks she wants to try it; sure enough the original T1 was recalled for frame failure/weakspot.
Fiido did good on the recall and sent out a replacement T1 with frame improvements.
I modified the improved T1 for the wife to try out, shorter crankarms, sweepback handlebar, short stubby stem, and off she goes with it.
Next to the 12" wheel e-scooter, which uses the same battery as the Fiido T1,
She likes the extra stability of the fat tires on the Fiido T1, I try not to give her too much to think about, just let her try things on her own, let her decide what she wants to ride:
Back in FEB this year, I ordered the Lectrik XP Trike for my in-laws.
FIL in his mid 80's used to ride his fat tire ebike to his fav fishing spot (2 mile from their house in Queen, NY) prior to the pandemic.
Both in-laws have diminished their outdoor activities since their neighborhood was one of the hardest hit by COVID, the new TV footage that showed hospital with semi-trailer full of dead bodies, that was the hospital that my wife was born in.
The in-laws used to enjoy outdoor activities, now they have very low stamina, poor balance, poor flexibility and generally weak physically.
Their neighborhood have plenty of room on the streets, besides, their operation of the trike will likely be very limited and heavily supervised.
The XP Trike is just an activity to get them out of the house, I don't think they will use it more than a handful of times in a year.
Wife hopped onto the trike last weekend for a few miles, she wanted to continue riding the trike because she enjoyed it so much, I was a little tired after a full day of yard work. Here's a picture of size comparison of her micro ebike vs her Fiido T1.
