Ok I took it out for my first ride today.. 26km all up the last 3 were full pedal - no electric assist. which is ok, it's good to know I can do it
it was about 50/50 split between road, and hill trails, and the ground was very soupy / sticky from a couple of days of solid rain so the bike was working pretty hard I think. In all I am absolutely thrilled with the end result.. it will cruise at 40 - 45 km/h with no pedal assist. my gear ratio doesn't allow much useful input at anything above roughly 37-38 km/h, powering up hills at 35+ is awesome.
On the trails, up inclines at 30+ in the bush adds a whole new dimension to off road MTB trail riding. The factory supplied rear tyre is a bit average for bush use but wasn't too bad overall. It's nice to be able to enjoy the trails without tearing them up like a motorcycle would (even a small pit bike would damage the trails).
Ok so the battery box is next on the cards as well as a Cycle Analyst so I can keep track of things.
The camera angle was bad, everything actually does fit inside the battery box outline with a few mm everywhere for box material thickness and rubber protection
There is also a Youtube of my mate taking it for a test ride, doing a section of a medium grade climb.. with very little pedal effort (slacker), perhaps that can wait for another day.
