Manufacturers tech support frequently has the answers if they are any good.
Remember that a bottle dynamo is driven by a roller rotating against the tire sidewall and the more power you pull from it the more resistance to rotation there is. Bottle dynamos are best used with tires that have a dynamo drive track moulded into the sidewall such as Schwalbe city and touring tires do to prevent sidewall wear. Also the bottle dynamo can slip in wet weather if that is a concern to you. I recently bought the Dymotec 6 and installed it but have used it minimally so far. I have it feeding the Light On! Dymolight headlight and taillight and have Schwalbe Marathon Plus tires on the bike.
I had to make my own mounting bracket as nothing in the way of commercial dynamo brackets would fit my Swobo Dixon aluminum frame or fork. I am a hobbyist machinist so it was a interesting project. The bracket I made mounts the dynamo ahead of the fork on the right hand side.
