Ive ridden my BIL's fat tire ebike (Rad Power Bike) and it was great for the most part. Good suspension, brakes, handling. 5 levels of assist, top speed of 20 mph- a bit more if its down hill and you peddle hard.
I didn't like the way it tries to accelerate when you are trying to slow down for a stop. I always downshift and peddle slow... that's deeply ingrained in how I ride after decades on derailleur bikes. When you do that with this one it thinks you are accelerating rather than slowing and jumps forward.
Here it is now prior to my son abusing it for fun.
If I was to buy one, I'd like this one or the off road version from CAKE
