I read mixed reviews from utilizing front hub ebikes. The main concern appears to come from making turns with a front hub ebike while the engine is locked in. Are the worries substantial or is it misrepresented? I have a rear hub bicycle and am considering adding a front hub iMotor to assist me with my slopes (5 degree for more than 4 miles with 12 degrees at a few points). Having the extra 250 watt will truly help and I anticipate using it principally on straight areas.
