Hey there!! names Keiff and im kinda new to the motor bike thing. Im familiar with little 49cc engines and scooters then stumbled upon a Derringer and fell in love. Figured I had all the parts myself why not make one. So I did, was great for the first hour and then fell apart.. I trashed the scooter motor and bought an engine kit off craigslist for 50 bucks!!!! had some complications with my cruiser coaster brake so i strapped it to an old french racer i had and will soon turn it into a Touring Boardtracker of some sort. if there are any seattlites out there lets get in contact and ride out!
