Thanks thats brilliant any idea on prices pleaseDo you mean an e-genius 920 ?.
If so then yes. I've the same bike and theres provision for it on the up tube bosses- theres a wee plastic bit between them. I think thats removable and you feed the wire into the tube that way.
You need the additional battery but also an interface bit you bolt on first, then mount the battery to that. It recognizes both batteries are interlinked. I think it a case of you must have this part fitted. Then just a case of picking the Bosch battery size you want(300/400/500) and iftting that. From there i imaging you need it all set up by the shop to enable the dual system
