Pros:
- Ebikes help people punch above their weight class, allowing them to bike farther and faster
- Going uphill is much easier
- Ebikes encourage people to be more adventurous and discover local scenic routes
Cons:
- Good ebikes cost as much as my 2007 toyota
- If you drive a hub motor and you get a flat (and you will eventually), it's harder to fix it up
- They tend to be rather heavy (harder to drive without assistance), and lighter ones cost a lot of $$$
- I am worried my bike may get stolen a little more
For those interested in getting an entry level ebike and living in US, I recommend REI's gen 1.1 and 1.2 ebikes. They're 40% off(!) right now, which seems to be a rare discount for ebikes.
