Loud clicking noise from Enviolo (2022 Turbo Vado 5.0 IGH)

[Nonlinear]

Hey all,

I've had my 2022 Turbo Vado 5.0 IGH for about 2.5 years. Six months ago or so, I noticed a loud clicking noise that seemed to come from the back wheel area. It occurred while biking up a steep hill just a minute or so after starting up the bike (coming out of an underground parking garage). The noise only happened for about 5 seconds, and I didn't notice it for a long time after that, so I didn't really pay any attention to it.

However, it's happened a handful of times since then, and seems to be getting more frequent. (Unfortunately I don't have good data on it, since it's so infrequent, and of such short duration.) Today I seemed to notice it may be comign from the Enviolo hub.

Has anyone had a similar experience, or know what might be causing it?

Thanks!

Which version of the hub is it exactly? My first impression (I would need to hear the noise to be sure) would be that the freehub needs attention https://support.enviolo.com/hc/nl/a...ean-the-freewheel-on-a-hub#video-instructions

If you ride along with a freehub which does not catch the hubshel teeth it could end up in replacing the entire hub because the aluminium of the hubshel will be eaten away byt the freehub teeth.

Thanks! This is the Enviolo Automaitq hub... beyond that, how can I tell what hub it is? The Eviolo app indicates product AHI 3.0, part number 6782-2100-0200, and hub model SP. The app also reports "no error" for the error status.

This only happens very sporadically - perhaps 5-10 times in total (though it seems to be of increasing frequency).

Ok, an automatic Sports hub, forget the automatic part. In most cases it would be the freehub part. It could also be the belt skipping or the sprocket on the freehub. When was the belt tension measured for the last time? Does the belt show signs of wear (belt no longer has even curved "teeth" but more pointy and loose hanging threads)? And can you check if the sprecket on the rear hub has excessive play?

Might be wise to see if you could let your bike checked at the LBS for tension (I do not think you have a belt tension measuring tool at hand?) so they can check the belt, sprocket and freehub. 2.5 years would also be a logically point in time for a service checkup on the bike (dont know when the last service has been and what the milages would be)
