I've tried the Kamoya Turn and the standard roller on an L-type fender, but so far none of them has shown any where close to the same stability and ease as a rack.

Does anyone know of other alternatives that can compare to the rack? I'm tempted to just go back to it.

Yeah that wasn't the problem. I think they're so brilliant so I've bought one for each Bromptons (got one then ordered another a few weeks later).

Guess I was warned against removing the rack but my mistake was believing the Kamoya Turn could resolve all the maneuvering problems of the single wheel.

I removed my rack and I was ok with it but it was a tad unstable. I sold the bike before toying with it further.
Have you considered using the front wheel as a stabiliser. I thought the bike could be wheeled possibly with a bit of thought using the wheels.

I don't see the point to remove fender then add Kamoya Turn...

We are thinking about this type of mudguard wheel mod. do you think it is feasible.??

I tried that and it didn't work because the angle of the vertical pin wasn't right. I had a castor like that but instead of the pin, it had a flange. I screwed the flange to the mudguard and that's when I saw that the swivel axis must be vertical when the castor wheel touches the floor. With mine which had the flange, that wasn't feasible. So I abandoned the idea. If you can find a nice elegant way of making the swivel axis vertical, then I think it might work.

Ha, so this have been done before.

the picture is just an idea, two bearings (one at the base and the other on the wheel) might solve this issue. How to fit them on the fender properly? we have to figure it out.

I guess I'm too spoiled by the stability of the rack to accept anything less.

With the Kamoya Turn it rolls with a pronounced curve, and would tip over from a light breeze. I'm too technically ignorant to investigate anything that requires metalworking, so I guess it's back to the rack for me, or this, which is currently out of my price range:

Someone there makes that? what else does SinG make for Bromptons.. what's SG$ to U$D rate.. .8:1 today ..

I just use the road wheels & unfold it..


looks like the Titanium hardware substitutes at www.bike48.com, for Bromptons

will keep Keyven's Charge Card busy for months to come ..

5-6 of those those caster ball wheels would be good under the chair I'm sitting on.

Well, in Singapore I have to carry/roll the bike almost as much as I ride it. I don't have hundreds of miles of rural roadways here, and pretty much constant 90+F daytime temperatures and over 80% humidity year round. Also, rain is common in our equatorial climate. There is almost never any reprieve from traffic flying past and zero designated bike lanes - cyclists basically have to share the bus lanes with even bigger vehicles.

That means multi-modal transport plays a decidedly sizable role when I'm commuting. Hence, why good practical rollers is so important in my situation.
