This the best one i have of the drivetrain, sorry I dont have one with the fenders off. If you zoom in you can see the idler sprocket going to the front wheel. Its really nothing special just the kit wheel and sprocket. Thanks to Jesse Sprague for the awesome paintjob. The battery sits right on top of the motors–it was the only place we had left for it. The little arm with the 1559 on it clamps down on it to keep it in place. Pretty nifty.
