Yeah it can be a bumpy ride. It really annoys me that you can’t change the wheels.

They do come off and you may have a slim chance at replacements off eBay. But the wheels themselves can’t come off to be replaced with something that has more shock absorption or traction. The double set of wheels are riveted together onto rectangular metal sleeves that click onto the legs of the frame.

At least they’re solid wheels so you can’t get a flat. 😔

I have considered stretching larger tyres over them as if they were inner tubes but that would require guesswork to buy tyres online that might not fit well.

I’m not a car or bike person but I’d think you’d have to consider both diameter and width.

And because it’s mostly welded in one piece you can’t even do anything with shock absorbers or an axel.

I could remove the rivets by damaging them and re-rivet some different wheels in but that’s a last resort repair. Don’t have the energy for all that.

I basically just put extra padding in the capsule to help cushion the cat and went carefully.
