Custom Motored Bicycles

Specialty parts for bicycles and motorized bicycles designed and manufactured in the USA! Due to high gas prices in fall of 2007, I started to make motorized bicycles. A basic motored assisted bicycle complete and ready to ride is $950.00 much more practical than a moped and with more functions, you can chose to pedal or not, on the fly. I have always enjoyed the past time of repairing and maintaining my bike, so I made my own scooter bike. Motorized Bicycles get 120+ miles to the gallon and go 30 miles per hour, legal to ride on the street with no special license, plate, or registration. The 2 cycle motor adds only 18lbs to the weight of the bike, smaller than a moped, 60LBS total weight and more compact for easy parking and commuting. All of the bikes pictured on this website have been personally hand built by myself Lynn. The bikes can be pedaled at anytime as a normal bike, more versatile than a moped. I hope you enjoy this sport as much as I do!

Harley and Davidson thought it would be easier if their bicycles had motors on them,from 1901 to about 1916 their motored bikes still had pedals. Have We come full circle? 120+MPG and speeds up to 35+MPH you can pedal along with the motor or without it. The 2 cycle motor adds only 18LBS to the weight of the bike smaller than a moped, more versatile, easy parking and commuting. Mechanically simple for less maintenance. The bike has a twist throttle on the right grip and a clutch on the left that you release slowly to start. Parts and motor are available for you to do it yourself for $220.00 with local installation assistance. Great green project! Call for a demonstration appointment anytime! Lynn 414-732-0017

                                      It must be a mens bike for the gas tank to go on the top tube. I hope you got to look at my website it has lots of pictures.  It is a motor assisted bicycle so you can register it as a bicycle if you would like,you do not need a moped license plate.The motor is a new 2 cycle motor that uses a mix of oil and gas 20:1. These motors are known for low weight and high power output, used on boats, weedeaters, light mopeds,freestyle motocross motorcycles, chainsaws and snowblowers.The result is very similar to an old motor cycle that you can still pedal and parts are easy to get because it is a bicycle, very economical.Obey bicycle laws and respect people and there pets and children. The motor can be turned off with a push of a button in very heavy traffic, bicycle parking is free.Thanks
