Need advise on what frame will work

[ArtPayne]

I have a specialized rock hopper 29r tht I use to trail ride & I'm 275lbs ! This is a great bike tht i really am reluctant about motorizing. I've been researching & found that Micargi makes very nice cruiser frames so my question is that if I purchased one of their frames which one would be able to accept a rear 80mm rim & tire! Has anyone built a wide rim motorized cruiser with a four stroke tht propels heavy guys like me around ? let your inner child ride

Try venice motor bikes they have alot of wide tire bicycles with the inframe 4 stroke

Welcome any of the motor kits will pull you around just have to gear them lower and pedal to help them out. Hope you have some deep pockets to buy the wider then 2.25 tires http://www.niagaracycle.com/index.php?cPath=8_81_8108_810803&sort=2a&page=2
