Hi

Thanks for the reply.

Although the specified tyre is tubeless, the tyre needs a tube because the hub motor isn't like an ordinary rear wheel, but has a removable rim, which means a tubeless tyre won't work. But also, all standard inner tubes of that size have the valve in the centre, which won't fit, because the centre of the wheel is directly into the motor, so the valve hole in the rim is offset by about 45 degrees - hence a non-standard tube is required.

I'm hoping the manufacturer still makes or stocks these items,

Thanks for any help
