If your motor is with 1500W or 2000W, then the Taiwan Molicel INR18650 P26A would be suitable for you because it has a high discharging rate; If you leave in a cold country and will use the bike in winter, then the Taiwan Molicel INR18650 P26A is also suitable for you because it can work under -40 degree. If you prefer the Samsung or Panasonic cells for your high power motorcycle, please choose higher AH for the battery, small AH with larger discharging current is not good for battery lifespam. 

We can build the batteries with your demand dimensions. You can have a rough size calculation according to single cell dimension: 18*65mm(Diameter * Height), 13S4P layout means 13*4=52pcs cells, 13S5P=65pcs cells etc. Leave some extra space for the cell holders and BMS(normally 80x60x12mm for small current, and 100 x 140x 15mm with larger current.).
