Very easy motor fitment, straight in. Juts had to file the BB center down as some material was catching. Plenty of room for any battery on down tube.

This awesome little polygon zeta 2 makes an excellent electric bike conversion. Super fun and stable to ride, and the BBS02 motor kit and 36v battery means that this little bike has plenty of commuting and hill climbing power.
