For that example, if you do a pretty full discharge (daily?), then you will need about 48v x 11.6 ah = 557 Watts to recharge.
If you get a little 50W panel, then it will take 10+ hours of peak power charging to recharge. But, expect to only get a few hours of peak charging a day. So, it would take several days to recharge.
Say you get a 250W panel, then it should recharge your bike with about 2 or 3 hours of noontime sunshine.
What are your goals?
Recharge while at work?
Recharge at night while at home?
