Batteries and electronics don't like to bend. For that reason, we recommend choosing a skate deck with little to no flex. This is especially important if you intend on going at high speeds (>35km/h). This is why we designed the Raptor 2 with a rigid deck, optimised for high-speed e-skating.
Choosing a deck without a drop can also be beneficial, as it gives your motor mount more clearance, and keeps your electronics higher off the ground.
All in all, the deck is in the end your choice- you can make a dropdeck or high flex deck work, it will just take more ingenuity to keep the electronics from bending or brushing the ground. It has successfully been done before by our customers!
