Rolls like a dream im sure, but a downside to those is weight. 8 sealed bearings will be heavy.

NB: rear rack wheels are mounted on a 5mm bolt, the 2 on the frame rear section ,
part of the bike rather than the rack. are a 6mm bolt.

so your wheels bearing ID should reflect that,

Hmmm, if you have guards and a rear rack on a Brompton you are hardly going to be bothered by a little extra weight

I on the other hand have the titanium S-type with no guards or rack and every gram matters to me I never wheel my folded Brompton ...... because it is light enough to carry

Nope, ridden every day to work, all year round and in all weathers. If it is raining really hard I'll put on some water proof trousers.
I run with Kojak slicks so maybe they don't pick up water like treaded tyres? I certainly don't suffer from wet / muddy streaks up my back.

Titanium is a sure way to make your pockets lighter. ;-)

I think the weight penalty must be severe. The Brompton ezy wheels are very light being the width of a single bearing; I don't have one handy to weigh but I think they're something like 30g each. I was originally going to put 100mm skate wheels on my brompton but they'd weigh LOTS. What, 120g each? With a rack and 4 fat wheels you're probably at near to a 13kg bike.

If there were a simple DIY method to cut a skate wheel in half and keep a single bearing firmly lodged inside, that might be useful. Loctite perhaps.

Do some inline skate wheels have plastic cores? The ones I've seen selling dirt cheap are metal and I guess they'd have to withstand huge forces for their intended purpose.
A single bearing is only around 10 grams so perhaps some skate wheels are fairly light?

ezy wheels work just fine, eight bearings and four inline wheels are a bit redundant/dead weight, unless you are Tony Hawk going 20mph in shopping mode....then bearings make more sense

My bike arrived with ezy wheels and no rack/fenders. I installed 80mm inline wheels but they where too wide and interfered with pedaling so i went back to the original ezy wheels.

It would be nice to have larger wheels that are not wider than the ezy wheels. Will provide more clearance from ground for the elastomer when pulling the bike using the handlebar.

Easy Wheels sold on this site are nice. They are also not as thick/wide as inline skate wheels which means less chances of your shoes hitting them as you pedal along.

Interesting. The spec says 49mm. Is it the same diameter as the stock easy wheels? It would be nice to have in the 70-80mm range.

there is benefit in a wider track of those wheels..
the folded bike is less likely to tip over.
while parked..

Eazy wheels are around 60mm. There's a couple of reasons why I might prefer slightly larger wheels as a result of my own imperfect mods. Plus under load with bike as shopping cart Eazy wheels can shimmy a bit. . . dual bearing wheels would be more stable. The ease of shopping cart use will have a lot to do with whether I keep the Brompton.

I really like those hinge clamps. Has anyone ordered from these guys?
