I'm brand new to motor bicycling. I have a sixthreezero evryjourney bike (https://www.sixthreezero.com/products/evryjourney-mens-touring-hybrid-matte-black), I want to install a 49cc or less kit. I've been looking at KMB, BikeBerry, and most recently, Golden Eagle. I'm trying to compare a kit, similar to this, from KMB (GHOST RACER 7G T-BELT DRIVE V-MOUNT KIT SPECIAL EDITION WITH HUASHENG 49CC 4-STR - https://www.kingsmotorbikes.com/col...al-edition-with-huasheng-49cc-4-stroke-engine, versus the rear mount from Eagle (THE X38 GOLDEN EAGLE KIT – 38CC 4 STROKE ENGINE – 36 SPOKE - https://www.bikeengines.com/shop/4-stroke-bicycle-engine/ I know there is $270 difference, but ultimately, I would rather spend the difference upfront, IF, it's worth the initial cost (easier install, maintain, adjust, etc). I'm "handy", but not a mechanic, by any means. Just looking for some sound advise on first build, to be satisfied with my first ride!
