Crystalyte Controller Upgrade?

[Bone]

I've got an eBike that has a 72 volt battery and a Crystalyte 5304 Series Direct Drive Rear Hub Motor. Both the battery and the hub are good, but the controller and cycle aynalist are bad. Is there an alternative controller and cycle aynalist (display) that can be used to get the bike back up and running again? Thanks,

Oh yea, the model number of the Crystalyte controller is X-CT7240F 72V 40A 3305 7240F.
