Started as a 24" boys mountain bike.
It has 20" rims now with a six speed setup.
Engine is 33cc Japanese 'Zenoah' two stroke made by Komatsu.
Has a new carburetor with a choke so it starts fine in cold weather.
Super lightweight and easy to store, being a two stroke.
Top speed is low, 20 to 25 for a 160 pounder.
Centrifugal clutch and front and rear brakes.
Tame enough for a ten year old, I would say.
I only have email, but i can conform to your schedule if you let me know a few days in advance when you want to see it. Thanks.
