Ebike range and speed

I forgot to add: The bike pushes me to a little over 30mph (I'm a big guy) on flat ground. With no help peddling, I can cruise a little under 20 miles at or around 20mph. If you gun-it for long...

One bad thing about the Rockshox is there are no decent fender options. You can find one on the frame, but you still get hosed with water and road debris. I bought a cheap plastic kit...

An issue that I have address very soon is the lower mounting bar for my rear rack. It has bent and I'll have to replace it with something stronger. Dropping off of curbs has done this damage.
