I have had two GEBE machines and but for the first one being stolen I have no complaints about either of them. On balance I think I actually prefer the Zenaoh engine - its a little more forgiving on starting and I think if anything a little stronger and gives more torque, although that could have been because it was on a MTB frame.
I have nothing but praise for GEBE
. I am curious now as to getting hold of a Chengine so if anyone has one going second hand for fairly cheap (money much I dont have) then let me know
