My wife and I purchased Step Thru E Bikes from Rad Power Bikes. They only sell on line. They are located in Seattle. The bikes are between $1299 and 1499. They have foldable, off road fat tires and ones like ours that are for the road. 5PAS, 5 gears on a number of models. There are deals now, in some Costco stores they do have coupons to purchase for $1299 which includes a couple of the usual Costco extras. Or you order direct and they are shipped free.
Two things we did before buying was finding a location to ride them, which we found about 25 miles from our home. The other was whether there is a bike shop nearby that will service them. My bike shop highly recommended them, and he sells Trek ebikes and a couple of other brands, though he doesn't stock them. He has assembled quite a few.
When they come there is some easy assembly, which we did, then took to bike shop and had him put on he pedals, make sure everything we did was right, etc.
Because we ordered 2 we were able to take $200 off, so they ended up being $1399 each.
They have other discounts, veterans, referral (will refer you if you want, $50 off.)
Some bike shops won't work on any ebikes, but they are exploding, the biggest area of growth in the biking industry. Good Luck. they are fun, and I continue to ride my regular bike as well.
