ok... that chain business.... one could lay the bike on the non drive side right ? and therefore eliminate that perceived problem....

To the original poster... The 16 inch presto lite is a good cool 16 inch bike, with very similar folding size than the Curve, if the Presto ia one of the lite versions its also very very light ....
10 lbs less than a Brommy ? or is that just a little to subjective ? Our Brommy friends will chime in that weight doesnt matter ... same as I say that the chain on one side doesnt matter ...
right ?

if you can find a Presto lite .. and are not 6.3 tall... or dont want to spend thousands ... go for it
