For insurance purposes my old Specialized ebike requires a model name; even though it's not valuable. Does anybody recognise it? I got it secondhand and with help from the forum have repaired and modernised. Converted to direct hub motor from old independent motor with thin drive chain to hub, and also changed from unbelievably heavy lead acid batteries to lighter modern type. Thanks Chris. P.S. Any idea where the serial number might be stamped? I've looked on the underside of the main frame without luck. Thanks.
