Our first official review of the Joule HG Dynamo Wheel/Trelock Light Kit will be in Bicycle Times, Issue #24.
Adam Newman, Bicycle Times Tech Editor, reviewed - and subsequently bought - the dynamo wheel & light kits and had some good things to say about them in an email, on May 8, 2013: "... I'm super happy with this wheel and hub!...It's perfect for the kind of riding I do (on this bike anyway)."
He installed them on his nifty touring bike, shown below (click image to get a closer look at the Joule HG Dynamo Wheel and the Trelock LS875)
Here's the review. Enjoy!
