Great Metalman
Your odometer reading of over 8000 miles tells a lot about durability of Eplus bikes.
I never opened motor but opened front hub battery many times and must say it is pleasure to see how well is it constructed with high quality of materials like sealed Japanese bearings, precision aluminium casts and electronics which doesn't look like amatourish rudimentary assembly seen on cheap kits.
Very well designed in USA by STG Electric Motor Design. Now I regret I didn't buy another Eplus.
