I am 6'5" and about 106 kg. I have a leg brace because of a fused ankle on my right foot and have thuis lost the use of muscles (for pedalling) below the right knee.
No matter, the bike performs well, and the wheels are incredibly strong: 4X lacing, 48 spokes and PW hubs. I am teasing myself with a Perth-Sydney proposed trip next June-August, but am starting to think about using my Greenspeed GTO on the 4200 km route simply because I can do more km with the GTO and also won't need the robust strength of the Arvon. Self-supported (again) I can only afford 42 days on the road - less would be preferable. Hence the GTO leanings..
Arvon sent me a diagram for my missing front racks and "shelf" and asked me to wait until the fall to send pics because of computer problems. If you carry the copies on a flash they will be fine. Send me a pm with a (I think) telus.net address and I can send 2 mb high resolution copies.
