We have a Giant Halfway (mine) and a Dawes Kingpin (my wife Ann's). We chose these because we
both prefer the ride of 20 inch wheels, and they are good compromise between price and quality.
The Giant has a great ride, and has proved very corrosion free (important on a boat). However,
it came with stupidly low gearing. I've made it acceptable by fitting a bigger front cog - 48
teeth - and fitting a Shimano MegaRange (13-34) on the rear. Ann prefers the ride of the Dawes,
which also folds more neatly. But many of the fastenings are corroding. I've fitted a Shimano
MegaRange to the Dawes as well, so that Ann can get up the same hills as me. Actually, the
limit on hill climbing is about 15% (1 in 6), before the front wheels lift completely.
