All the parts on premium eBikes are the same as normal bikes, so any shop can change them, custom build you one, or sell you a frame / motor combo. We have to build over 1000 bikes a day, so there is no chance to offer custom factory builds when you are a brand at KTM's scale. The changes have to be made at the dealer level. But its totally possible.you need a self build option or at least let you pick the parts to make it ur own.
