Put this up on the FB page and then realized this was probably a better place to ask: the $1699 Duo Mid offering on Indiegogo fits my budget right now. I love all the spec especially the 52 V battery at that price, but am concerned about the cadence sensor for anything more challenging than gravel riding. Have any of you used a cadence sensor'd Juggernaut for singletrack or steeper trails? Has anyone tweaked the programming of the BBS02 motor or did the stock programmig work for you?
