Last 2 things I can say that work before I return the rush/cty speed
SR Suntour SP12 NCX Suspension Seat Post with Protective Cover 27.2X350mm - no shim needed
ROCK BROS Bike Bag Waterproof Top Tube Phone Bag Front Frame Mountain Bicycle Touch Screen Cell Phone Holder Pouch Compatible with iPhone X, 8 Plus 7 - I don't use the phone pouch as I have the quad lock mount already. This wraps around the top tube perfectly and the strap next to it fits the frame perfectly. The last strap closest to you is just kinda there. Recommend a wrap around the plastic bits so they do not scratch the frame.
Returning the bike as I got what Serial 1 recommends on the site. Got the medium. Stand over height is great, but the lean to the handlebars suck. After about 6 miles of riding, hands started to go numb. Another rider same size as me had the same issues. More of an upright rider.
It is a fun bike. I just want something I can customize a tad bit more than this bikes allows. Plus, i got to ride a mid drive, with an automatic 'geared' bike. Restock fee in this situation is just a rental fee. It is helping me with my next purchase.
