It all depends on your needs. What I found is that once you get used to riding it, you will be happy that you got. But trust me, 28mph is very fast on a bicycle, and it can be fun, but most of the time you won’t be going that fast.
More importantly than that is to first find out from your state if class 3 bikes are allowed. Some states restrict them and I have read in the past that they were not allowed in New York. Bike shops and manufacturers will sell you what you want and if you find out it’s not allowed and you get caught, they can confiscate your bike. I don’t want to belabor everything that I’m telling you, but you need to have the answers first. I promise to get back to you with any advice when you first the the bike law answers of your state. This e bike evolution is getting so big, that the government will be getting involved, because there is money for them to be had, ;registration,license,inspection, etc, etc.
