You want to be able to go 90km (55 miles)? That is really pushing it unless you go with a pretty large bike. However, I see your management system is for a lithium battery pack. This should allow you to pack enough batteries to get the range you desire. I would estimate that the motorcycle will use 250Wh/mile. Since you want to go 55 miles, you need at least a 14 kWh pack, preferably a 28 kWh pack to keep your depth of discharge up and extend battery life.

Since you are going with such a large pack, I'd go with as high of a voltage as you can to keep the amperage down.
