thank you once again, the drop offs measure 12mm,however after doing a battery mock up it appears the battery will not fit and thats taking the dimensions of the hailong 2 found here http://www.topbikekit.com/hailong12-battery-48v16ah-panasonic-bd18650-liion-battery-pack-for-ebike-p-756.html I guess I will need a bigger bike or a smaller capacity battery or an ebike?
