It will be my first in frame motorized bicycle. I've rode electric and friction and now I'm ready to ride with the big dogs. I'm not a mechanic and though a 2 stroke china girl could be in my future once I learn more, I want to go with a 4 stroke. Are all the kits the same? Sure looks that way. Who should I buy from? What issues should I look out for?

I know china girls are cheaper, quicker and look better but I feel a 4 stroke will be a better fit.
If this has been covered I apologize

I have a EZM kit and I love it. I bought a mounting plate for it from Bicycle-Engines dot com though as I preferred the construction of it over the EZM one. EZM may have changed it by now, I don't know for sure.
The EZM kit is bulletproof and I highly recommend it. It costs more but is very, very well worth it.

Bicycle-Engines dot com also sell a great kit called the 4G T Belt Drive.
I have learned through the experiences of others that the 100 tooth kit with the solid pulley is preferred.

GasBike dot com also sells a variant of the 4G T kit that has a slightly different engine and clutch configuration that has been touted to be a stronger assembly, however folks recently have been receiving poor customer service from them. Caveat Emptor.

What ever you choose do not get a kit with the Grubee SkyHawk stage III chain box.
They have proven themselves poorly made and have a short life span.

Research this forum and learn the tips and tricks for whatever kit you choose before purchasing it. That way you will have a better understanding of what to expect during it's lifespan which can last 10,000 miles or more.
