The Bosch motor housing doesn't have mounting point for a double, center kickstand but the stock kickstand itself is sufficient IMO.
With Big Ben tires, rack and fenders, it can be turned into a wonderful commuter as well.
I got a Pedego kick stand for my Evo Jet. Works great. Single leg but very sturdy. The Evo jet factory kick stand was flimsy and slight touch to the bike and down it went.
