This is the CYC X1 Stealth e-bike conversion kit. (with the updated gen 3 controller) and 52 volt battery. cost $3200 just over a year ago. it's a seriously powerful motor (rated at 1500watt peak output). it's about twice the power out put of your average high end e-mountain bike. the kit includes; the motor and control unit. freehub drive assembly. cranks and bottom bracket with torque sensor. 52v 17500mAH lithium battery handle bar remote and screen that shows speed etc. basically everything you need to convert your existing bike to electric. with the proprietary app you can fine tune the settings to suit your own preferences and riding style. i had this fitted to my Cotic Rocket (also listed on trade me) and it was amazing. i could fly up the hills and then use the bit of extra power for some boost down hill too.

if anybody is interested in the cotic rocket with e-bike conversion as a combo please let me know. please see my other listings. Cheers
