Changing a tyre on chainless bicycle

The canvas was starting to show through on the rear tyre on my Bollwell S7, changing it turned out to be much simpler than I had expected.

First undo the thumbscrew on the SRAM gear assembly and remove it.


Next remove the plastic gear cover by taking out the two philips-head screws .
Undo the wheel nuts, the wheel is located in the correct position by special washers. Remove the wheel .
A view into the gear housing .
The gears still look to be in good nick, they appear to be attached with grub screws if they did need changing (I expect it to be quite a few more years before that needs doing.)
Change the tyre as per usual and reverse the process to reassemble. On the whole, less messy than the same job on a chain drive bike.
