First off, thank you Mitchell and Phil at SHRED support hotline and email, both very helpful, all questions answered and extra hints added in.
So, out of the box, this machine is very well setup, a real pleasure to look at the craftsmanship and style. The only thing I had to tweak was the disc brake pads, centering to the rotors, an easy job after watching a Youtube tutorial.
Before the 1st ride, I pulled a Suntour NCX suspension seat post, Cloud 9 commuter seat and wide palm handlebar grips from my 2 year old 1st Ebike and installed to the SHRED. The 1st ride revealed the cushioning effect of the 2.8" mid-fat tires, a very nice experience over the 2.1" tires that I was used to. The Bafang motor has plenty of pep and runs smooth via the cadence sensor. The 1st full battery (20AH) charge lasted 70 miles with 4% still on the meter, granted, the last 10 miles showed the slower speed effect from a lower battery state. The large LCD screen is easy on less than perfect vision too.
For sizing, I am 5'11", I find this M\L frame to be a perfect fit, very balanced and comfortable.
I experienced a dropped chain on the 2d ride out so I swapped the stock 38T chain ring for A Deckas 38T narrow-wide tooth ring, so far no drops. Pics are from a 23 mile ride around a gravel perimeter road surrounding part of the everglades just west of Markam park. Thanks SHRED team, kudos for sending a great bike my way!
