Here is a new way to do Dax's set-up.

YouTube - scooter guy motorized mountain bike 50cc titan from dax.com pedal option i"ve never seen this.

Interesting build , but that chain looks like an accident waiting to happen and also the motor mounted like that makes the bike look lopsided to me. But I really like his choice of motors and it sounded very quiet. I think my next build will have to be a 4 stroke due to there being so quiet

I Would Put The Motor In The Back, Before I'd Stick It On The Side Like That...but If It Works...whatever .its Gotta Be Heavy On That Side. I Would Like To Get A Four Stroke.they Sound Sweet.

yea same here Death, it just looks odd on the side like that

It's just another lesson in going beyond the spectrum. It's absolutely brilliant! But I would secure that engine a bit better. Looking at the video it seems it's only supported by the gearbox bolts? Are the motor mount bolts just hanging?
He does do away with the jack-shaft. But that chain looks like it needs a guard. And maybe add a storage box on the right so it looks more even.
But bravo! Gears! yay!
