Just received a brand new straight out the box Rad City 5 plus.  Fixed it all together, all the leads are connected and the battery is fully charged.  It will switch on and the lights work and you can adjust the power up to level 5.  The brake light works on both levers.

However when you turn the crank absolutely no power is going to the motor.  Even tried it on the road but it's completely dead to the motor.  This is brand new out the box.  I haven't contacted Rad support yet.

Any suggestions?  I have checked and triple checked all connections
