I can't believe no one else is posting about this! I had a honda express, 1978 (nc50) and I put a small wheelchair battery (10 amp hours @ 12v) and a car stereo with two brackett speakers. The moped was only 6v so I had to bring a battery-- It died (the NC50 not the stereo) so I broke down and bought a new Tomas Bullet. It's in the mail now,
I put the battery and stereo in a pannier pack which fit nicely on the express.
I don't want to overload the Tomas Bullet's system by running a 12v stereo off it. Has anyone else put a stereo on their moped??
I also have air horns which I plan on installing on the new ped.
