Hello any small Giant Lafree owners, I'm 5ft and need to know if I would feel comfortable riding the 'small' Giant Lafree, which I understand has a frame size of 44cms (17 ins?). I'd need to know the measurement from ground to top of seat. Around 30ins -31ins would suit my height. Also, does this model come with a suspension seat post which can be removed and replaced with an ordinary one (like the Powacyle Windsor) thus reducing the seat height by a couple of inches? I ask this because I am considering buying a second hand one that I won't be able to test ride personally. I have ridden a Powabyke and also a Powacyle Windsor. The former I found too heavy to handle (but great throttle power) and the latter was good, except I didnt find it had all that much power up hills - which is counter productive living, as I do, in Devon. Many thanks in advance for any enlightenment on these points.
