Thank you so much for your concern, Changing to an adjustable bike stem did help to relieve stress in my shoulders. If it could rake up just a little bit more it would be perfect for me. I changed stems on both of my bikes, My Zebra step Through and Cobra, This change made for a better ride with both bikes. For the Zebra I trust the adjustable stem should be a standard stock part in the future.
By the way I am on my 13th e-bike for over the past 20+years. I must say, I love your bikes. I tried your Step 2020 Through Cruiser as #11 and it topped most of my e-bikes of the past. I really got into that bike an dialed it into what I needed. And when Himiway advertised the Zebra and The Cobra I had to have both #12 and #13 and now I am really enjoying my retirement as of July 2022. Thank you very much for a wonderful product.
