I purchased two new I zip zumas. I live in corpus christi and there doesn t appear to be any dealer s nearby. I ve tried the Currie customer service line but can t get thru. One of the bikes makes a click from the rear hub when pedaling forward or backwards. it is silent during electric only operation. It is not a derailur or chain noise. It is not the ratchet in the cassette. It is deeper inside the electric hub and quite loud. The noise went away when I took the wheel off. The noise came back when the axle nutt was tightened back up. If the axle nutt is left very loose there is no noise. My guess is there is an internal freewheel that gets pulled out of alignment when the axle is tightened but I m hoping to hear from an expert. The noise is a loud slow click.....click....click . I thank you in advance for any help or perhaps a phone number that currie will answer.

Most likely it's the hub's bearings. This can happen even on a brand new bike from poor lubrication or improper torque when installed. Also you should always torque the axle nuts to spec with a torque wrench.

Thank you for the response. I suspect it may have been over torqued during assembly...The axle washer was stuck to the axle on that side. My local bike shop also pointed out the poor lacing on the spokes.....several stripped nipples and very tight. Is there a torque spec for this model. I have a very nice torque wrench.

Checkout page 63. Make sure this is for your model first, models listed on page 1.

I want to thank Shell Mitchel at Currie for following up with the tech department so my question didn t get lost in the shuffle. It was immediately and correctly diagnosed as a spacer issue behind the free hub. Chawn and Christina were very helpful in sending me a pdf document that outlined the very simple task of removing this little spacer from behind the free wheel. Took less than 30 minutes to fix. Now both my Zumas are silky smooth. The only clicks I hear are the ones from my bad knee! lol Thank you Currie and the good people at EBR for the guidance.
