Roll stability and comfort with turnable rollers that are further apart

[Zephyr]

Hi,

I’m using my brompton a lot for travel with a rather heavy and large T bag. The bag is also attached to the bike in folding mode, so I can roll on the EZ wheels attached to the rack. I have two problems though:

(1) the folded bike isn’t stable with the bag attached. The bag is not centered, and even if it was, the top weight would make the bike fall anyway with slight movement. I think this could be solved if one of the wheel pairs would have a larger axis, making the wheels stand further apart. Since I shouldn’t be touching the wheels while biking, that should be the wheels on the back of the rack. Ideally you could move them out.

(2) rolling the bike, even without bag on top, isn’t that easy in my opinion, because all four wheels have a fixed angle. For making turns, I have to lift the bike. In the end, I end up lifting the bike every few seconds to adjust my path. It seems it would be much easier if one of the two wheels pairs would be able to turn.

I’ve looked around but couldn’t find any ready made solutions. Any suggestions?

How much are you willing to pay?

Sounds like you need a GoRack...https://mygorack.com/

Failing that, this doesn't havewheels that turn, but there are extendable wheels.

Thanks for the link. Half-baked, especially important in the context of price, but there are some ideas there.

I use larger ez wheels, 80 mm, which allow a greater angle, when rolling the bike folded, so that the suspension block does not contact the ground or rolling surface.

It looks like it evolved from the sidewinder of a few years back - maybe that failed and they bought the patents or this is the same people, but there's been no mention of the sidewinder for a few years.

I think there was some problem with adapting SideWinder to the update of the Brompton rack. Maybe it was just not worth it - it is hard to make money on such a product. In any case, as I corresponded with the designer in the past, when I needed an additional set, I emailed him and he posted a set for me on Ebay.
