How much does a standard battery weigh? I wouldn't have thought it was anywhere near 4.4kg  :187:

Blow 2K on a pair of carbon wheels.
That'd be the best weight saving you ever do, it's like someone halved the weight of the bike.

My battery is a Yuasa 16 5.170 k not a 14 so have saved 4.4k I'd love a pair of mag wheels, one of the reasons I did not go for a xc was the weight of the wheels,

So it sounds like the replacement battery did not accept charging. I hope you haven't affected the rest of the electrical system.

On the plus side having reduced the bikes overall weight, it must be easier to push the bike around  :492:
