Not mine but I am planning to use the same 4 stroke 4 speed clone but 110cc vs his 90cc engine to build 1 slightly similar on the same frame. I intend to use the left side as you said for the engine drive side run off either an French Atom hub with a free wheel on the right bike side or this on your typical sized 1.5" coaster/disc brake. I am not running a belt drive or sheathe due to clearances on the motor, the fact there is No Clutch & with that Nirve Switchblade frame there's literally No Room for Error motoring 1 on a 24 or 26x3" tire as just the bike chain line is already so close with little room to spare. I will be modifying a once $600+ frame to make this happen, change the looks to more my liking, and to then make it look Vintage running Monark Super Deep fenders, cheese grater rack, Super Deluxe chain guard & my own little personal bicycle touches with what will essentially be a legit built motorcycle with a bicycle core. Should average somewhere between 50-100 mpg & top speed hopefully of 55+ mph.
