I bought a Radcity 5 ebike from Rad Power Bikes (
https://www.radpowerbikes.com/) in March 2022. I've been pretty happy with it. I commuted to and from work (~7 miles each way) about 3 days per week from May through August. I believe it is considered a "class 2" bike, which means it has both pedal assist (power proportional to your pedaling) and a throttle (speed control without pedaling). Further, "Class 2" bikes have a top speed of 20 mph, above that, the power cuts out. There is a way to remove the 20mph limitation, but the speed still tops out around 23-24 mph.
When new my bike would get about 40 miles per charge, but by now it gets closer to 25 miles on a charge, which is the "rated" range. The battery charger just plugs into a regular outlet. It takes about 7 hrs to completely charge.
As for the ride, it is pretty much like a regular bicycle. It is quite heavy, weighing in at around 65 lbs, but the motor more than makes up for that. You can adjust the level of "pedal assist" from 0 to 5. At 5, the bike really moves you and you should be able to reach speeds around 20mph with only moderate effort. Hills are essentially erased, as far as the effort needed to climb them, although the bike may slow down to 10-13 mph on steep hills. Still, it is very easy to ride this bike to work without working up too much of a sweat, even on hot days. I would highly recommend it.
The bike comes with a pretty good rack for hauling a backpack or groceries. I can fit about 3 reusable grocery bags, so long as I strap them down good with bungie cords. It can easily handle a routine grocery run, but probably wouldn't be my choice for a major shopping trip.
One comment, the radpower bikes are not particularly cheap, even though these are on the more affordable end of the ebike spectrum. Considering my relatively short commute, I doubt the fuel savings will ever cover the purchase price. Nevertheless, I love getting about 25 minutes of fresh air and exercise each way and it is certainly much cheaper than a car. In the long run, I think its the health benefits that tip the scales in the favor of the ebike. I have a conventional bike, but I never rode it to work because I didn't want to arrive all sweaty. The ebike remedies this situation, since I can ride to work in the morning mostly under the bike's power. For the ride home, I can reduce the power assist and get quite a good workout.
There are a lot of technical decisions that can bog you down in your purchase decision. If you do your research, you will hear about hub-drive vs. mid-drive motors, cadence vs. torque sensors for the power assist, and many other features. In my opinion, the most important things to consider are the battery size (and range), and the motor size. If those are adequate, you will likely have a good experience, even with the cheaper hub-drive motors and cadence sensors. If you have any questions, let me know. Good luck!
