Re: Hi All..glad to be here and to meet you all
Welcome to the forum! Nice to see another member from my hometown!
For your first build, I humbly recommend you do as much research here as you can. I can't help you with your mount question, as I'm an in-frame kinda guy, and I think a 212cc on a rear-mount would be a disaster. In my humble opinion, It's a lot of motor for a first motor-assisted bicycle build, and it's a heckuva lot of motor to be mounting up high on a bicycle in rackmount configuration!
