I just got my Juggernaut FS....and it also makes the sound you described. I only notice it when I stop pedaling and the chain ring on crank is slowing down...maybe it has to do with the one way bearing?
I just bought the Biktrix Ultra FS with the new Bafang Ultra motor...they said they ship it at full power.....can I hook a computer up to it and through software adjust parameters and possibly more power?
I would think the Ultra motor (1500W) with the added benefit of the bikes gears would be crazy strong....160nM of power! I'm glad to hear it's still running!!!
Awesome suggestions! I just purchased the Juggernaut FS and would like to get the rear shock and bash guard you mentioned. Any model #'s would be greatly appreciated!
