mine was cutting out so just replaced it with my spear one and it sorted it are gen3 just had a TCU and mode controller put on but that was throwing up a code but again I had spear parts
My what I call my spear motor has 2000 miles and is very loud it’s in my bike now my other motor has been sent back to ebike motor Centre it started to squeal like a pig
Good bikes but let down by the motor reliability in the last 4 months two different bikes two motor failures both with around 1000 miles probably getting near double digits on motor replacements
