I had been trying to get higher sustained speeds on the bike course I use, but at speeds faster than 14 mph in a hard pedal, the bike bag is floppy and throws off my rhythm.
I got a larger bike bag with two shoulder straps and two cross straps. This bag is big enough to hold the smaller bike bag, so I won't loose any utility. besides, I need all it contains, and its additional weight.
Its been raining here, so no testing for a few days.
I know that if I can maintain my balance, the bike is stable to faster than 18 mph. I do expect to be able to maintain a 13 mph cruise.
