Oxygen MTB annoying rattle – fix.

[JPGiant]

After weeks of gentle riding over gnarly bridle paths, pot-hole ridden tarmac and searching, checking and testing every component for an annoying rattle – it came down to a small amount of rotational play of the battery when fitted to the frame.

It was only about 0.007” each way and the battery never cut-out or brought up a fault on the LCD, so the connection pins must be a good fit.

The fix – four small pieces of rubber draught excluder, two at the top and two at the bottom of the frame pocket where the battery locates.



As part of the testing I removed the bike-stand, this certainly eliminated a big part of the overall rattling from the bike – although on good surfaces it’s as quiet as our other bike, a FS Giant Anthem.

Next on the list is to stop chain slap despite having a protector fitted.

JP there is a way to actually tighten the battery. Dale at SYEB showed me how to do it. If you give him a call he may be able to help you and explain better than I could.

That's interesting to know, I'll follow it up - unless someone else out there can elaborate.

Even on 2020 mk11 it’s happening

Tried sound deadening foam and hasn’t cured it

As I mentioned in my first post it only needs a very small gap between the frame & battery to create a rattle over uneven surfaces - either radially or vertically, tighten a Velcro strap round them both then go for a ride to prove/disprove the battery.

Along with the bike stand (which I removed), the other areas of 'rattle/clicking' I've found are:
Chain slap on the chain stay (which I sorted by changing the RD to a Shimano Shadow clutch version).
Slightly loose headset bearings.
Two loose spokes.
Dry front forks sticking.
Dry pedals clicking.
Dry chain link.

The list could be as varied as the complex bikes we buy and in no-way is it a downer on Oxygen bikes.
In most cases a little time and effort spent in tracing issues on the bikes helps us to understand their inner workings so we can pass the results on to others, hence the forum.
Thankfully, with a Mechanical/Electrical background, problems are a challenge I enjoy sorting.

The rattles definitely from the battery everything else is fine il do a video at weekend as the md at oxygen has asked for one and il post it up

The nut on the battery itself hasnt worked itself a bit loose has it? I would imagine that could make a difference
