I'm building a motorized bike. specifically i'm putting a 80cc motor on a beach cruiser but i was going to also attach one of these as well http://www.electricbikefactory.com/index.php
I planned on having a big basket in the back and putting a deep cycle marine battery in it to replace the little battery it comes with and having one of these charge it. http://www.harborfreight.com/45-wat...e=pe&ctype=2&gclid=CKrA8tiatqgCFQl_5Qod4S-RCA
i just got a ezip trailz bike from a friend but he didn't have the charger or battery. I see it has a welded on slot on the frame where the motor attaches and was thinking of adding this motor and its freewheel as well to my motorized bike that i'm building. I would have to get that attachment cut off and welded on to my bicycles frame but i'm already planning to have welding done on my bicycle so i can use my bicycles frame as and exhaust pipe and possibly welding on a back rack. viewing the side of the ezip bikes motor i remember it saying 48volts. the information on the electric motor that mounts on the front wheel says its a 12 volt motor and the battery that comes with it says its a 12 volt 18 amp battery. can i hook them up directly to the marine battery or do i need some type of voltage regulator or resistor or fuse or something? Is it worth the hassle you think to hook them both up? I only thought to do so because one battery for the ezip is 120 bucks and the charger is another 25 at least. both of the motors seem to say they do about 17 to 20 miles an hour. just listening to this after i've written it i've decided not to do it but i spent so much time writing this i might as well post it. happy easter
