I've been checking out the vintage motorbikes by Ridley. They use the felt cruisers as a base, and they are beautiful! The cool thing about them, is that the "tank" bar is actually a tank. On these bikes, the tank-shaped top tube is completely sealed, so at Ridley they tap a cap onto the top, and a petcock on the bottom, and no need for your ugly tank. Also, check out the sweet custom, billet aluminum frame mounts. They have a rubber insert that the motor mounts onto, so very little vibration...I called and asked if they would sell the mounts to me, as I plan to build up one of those same Felts, and "**** no" was the response...the price of the Ridleys are $1500, but considering the quality of the bike used, the bullet proof mounts, and they outfit the motors with noise deadening clutch,gear, and generator covers (black), it's not a bad deal...way, WAY nicer than those pile of crap Dehringers that are selling for $3500! Has anyone built up a Felt yet? Gimme some knowledge on what to look out for. I know I'm gonna need one of Andy's top-hat spacers to get the chain clear of the 3" wide rear tires, but the geometry of these frames is definitely unique...it's as if Felt designed them for motors...there's a lotta space between down tube and head-set.
