I received my Limited model last week and through Velotooler as Ride1UP recommended to check assembly and make adjustments. I actually paid them to assemble the bike and make all adjustments. I will go into important detail in another thread. Although I found the bike to be quite fast, I am reaching out to anyone who can "break the code" to program more speed for that occasional adrenaline rush or bragging rights in my neighborhood filled with several e-bikes.
