30a current is small right? For lik 1500 up to 2000 is 45amp? Normal current
Whether that's small or big, depends on your requirements, as MadRhino stated.
30A gives you just over 1500W continuous @ 52V. 60A peak gives you 3000W peak @ 52V.
Based on the simulator, you get the same speed, but have more torque for acceleration up to top speed, which looks to be about 40% quicker. At full speed, you're using around 1300W on flat ground.

If you play with the simulator, you can determine what will work for your first, then you can ask a more targeted question about what controller would meet the requirements, instead of adding more details as you go along as folks attempt to help you. Things like budget should be part of your original question, not information added after people invest their time in responding (this type of guidance is included in the stickies, in order for you to get your answers efficiently).
