This will make it's first public appearance tomorrow.

I can't decide if I should use black tires or stick with the white.

Dave, I've been following your blog/progress..great work! And I love the white tires!

Love it, putting that picture on the wall in my living room! I would say go with the black tires, black and yellow is a classic combo. Here, put them side by side...

Dave, Best Wishes on your debut, keep me posted.

Checked out the latest post on your blog, Nice score on the neck decal, I've never seen one before.

I'm only repeating myself,.....The bike looks great!

Thanks guys. It was a hit and was invited to be brought up "under the tent". Started on it's own all three times(only a 3.3 amp battery) and ran great. Huge attention getter as people were rushing to get out their cameras as it went by.
At the end I did a neighborhood lap on the way back to the truck. Fortunately, I was away from the crowd when the rear freewheel spun the threads right off the rear hub. Fair warning to those building anything with any power - you need a cush drive of some sort - the aluminum hub cannot take any power. God forbid the sprocket was mounted to the spokes! I will have to mount a sprocket carrier directly to the hub but will have to come up with a way to soft mount it too. Cush drives have been discussed as necessary since 191x. You have been warned.
Lot's of fun!!

Great job! I followed your blog also. Just too cool.

Thanks for the warning about cush drives, and nice power plant by the way, but anything the can break the rear tire scares me a little. Can't wait to see what you come up with to fix it.

Me too! Honestly the real problem for singles and clunky twins is the uneven power output causing a push/pull effect on the rear wheel. My issue is only under hard power as the belt on the primary reduction dampens the motor's compression strokes from the drive train and rear wheel during cruising. Secondary reduction is chain only. I might mount a sprocket carrier directly to the hub with as large a bolt pattern as I can and just remember "thrust is not the goal."

Here's a walkaround I did the day before the show. I wasn't zooming in on the motor, I was pushing the brake pedal to stop the rear wheel for a sec.
