I think it is either/or:Thanks for the reply Neal but iv taken the battery off and tried to ride it and its defo mechanical drag from the hub.if I get up to say 15mph without battery it freewheels fine.but as soon as I start to pedal it feels like the brakes are on.it really is that bad..
- a psychological effect
- motor needs running in for about 100 km
- clutch stuck in engaged position (you would hear the noise)
Your bike will freewheel fine because it is heavy and we have all (hub motor riders) been through the learning stage where we have felt to lesser or greater degree what you are feeling. Motor drag is about 3-5%, extra weight increases rolling resistance when you start to pedal.
