Total gears rate is 6,8 and one circle of pedaling moves the bike in 3256 mm travel lengh. With this pedaling rate I feel no any resistance from pedals (on flat terrain profile). Therefore, I think, the optimal gears rate must be not less then 9,0-9,5 for 6'' wheels. Sure, length of cranks should be increased up to the standad size.
I haven't heard anything on the gear of Mk-II, but i suspect the gear ratio will stay the same. I did quastion the A-bike designer about the gear ratio, and her said that it was intentional to make the gear ratio as light as it is now.
I think this decision was made in order to avoid stress (from pedaling) on the structure as much as possible. With heavier gear, A-bike would do just fine with flat road, but something like climing a small hill become more difficult and IF
a user try pedaling the A-bike in standing position (+ maybe twisting as well) could destroy the A-bike into pieces...
I know this sounds silly, but I guess A-bike team cannot really take chances as manufacturer --- their A-bike is not full-metal bike in the end of the day, you know.
Personally I'd love to have heavier gear on my A-bike, but I haven't really got time to work on the 15T gear project right now.
so my bet is that Mk-II will be structurely enhanced, but not functionaly.
