HPC 2500W Extreme Mid Drive Bicycle Conversion System Complete Kit

All new for 2019 is our 2500W high performance mid drive system.  This is for the power junkies who want the most power they can squeeze out of a mid drive system while keeping it whisper quiet.  This is our most powerful integrated mid drive system to date at 2500+ watts heart pulsing power.  Compared to the standard 1500W system, this system features an upgraded USA made 48V 17.5ah battery system for even more range and performance.  Offering a massive torque output of 165+ ft lbs, this is your best choice for climbing steep hills and hauling heavy cargo.  With the proper gearing and tires, there is not a more capable system on the market!   Sizing: This kit is for bottom bracket sizes of the most common sizes 68mm-73mm, 100mm and 120mm (fat bike). Other BB sizes can be made to fit with custom spacers. Make sure to measure your bottom bracket and know the size to put in the order notes.  HPC 2500W Extreme Performance Mid Drive System Custom Single Speed 30T sprocket Throttle Only
