pictures to illustrate earlier remarks about using clear wheels as a rear light diffuser.
sorry cant find a good photo of my older brommie with ,actually, 130mm scooter wheels.

I have a picture of my current brommie with 130mm , brfore i removed them and the rear rack. picture 1 and 2
The larger 1300mm clear wheels look speculator in the dark , but i dont have a picture. The ones I used are red cored ,clear wheeled scooter wheels look the coolist due to the red rear lcd lights.
I did also fit them on my mezzo but again not photos photos of current 76mm clear to show diffuser effect improving side lighting.

130mm is a tad too big as the wheels catch the front wheel when pushing half folded making it difficult to wheel. This happened on mezzo and brommie afaicr.

Honestly if you run a rear light they must be clear or transluant red, whatever size you get

the way to fit a rollerblade wheel re heel catch is to remove the inner bearing and epoxy resin the bearing to the wheel to keep it secure on the bearing. every thing else is standard afaicr.
