My Cube Reaction race 500 has developed a tick whilst riding it...

[Ianh]

I’ve covered 380 miles in a few weeks on my lovely ebike and it’s developed a ticking sound when I’m riding it..... I’ve returned it now twice to Evans cycles, and they’ve test driven it...and 3 different mechanics have puzzled over it,they’ve tightened up the cassette and all the nuts and bolts, the speed of the ticking noise seems to be at the same as the revolution of the wheel...and They’ve been unable to rectify it....
Anyone else had the same problem?
Uber annoying both to me and whoever I’m riding with...

If it is every revolution when you are peddeling it could be a slack bottom bracket.

It’s clickin when I’m free wheeling... I’ll try and tighten the bottom bracket, thanks

Thanks!

I’ve tightened everything.... and it’s still clicking in time to each wheel revolution

Might sound silly but have you checked the tyre for a stone or some other object stuck in it. Steve.

Loose spoke ?

Brake rotor ?

 

[Ianh]

Thanks, I’ll try all those things....

Front or rear?
Does it click when spinning the wheels with bike lifted off the ground?

 

[Ianh]

Problem solved!!
It was a bearing in the rear wheel... bearings changed and repacked with grease!!!
Silence!! ...... well just the whir of motor and chain doing their thing!
Thanks for all your suggestions!!

Well done, can't beat a bit of grease -
