Ok well after much stuffing around and a move interstate, some meaningful stats.
On country roads, up 450m and down 450m then back again I can report that the battery and leafbike motor can go
65k at an average speed of 30kph using pedal assist number 2 and sometimes 3.
The gearing is 52/11 biopace and probably need 54 to really get it going.
If I sit on 25kph pedal assist 2 I get 80k
I am adding another battery 48/13 to give me further range and I reckon one in each pannier will balance the weight better.
I am hoping for a good 100k range then, in lazy mode. My max commute to the shops is 75k so with a load will need extra grunt.
THe current LCD03 is not very accurate as far as the bars go so I have an LCD07 to fit and see how that goes.
Next upgrade is a new goose neck trailer for $150 and see how we go shopping with that.
Also no movement so far re torque on the axle. I didnt bother with the torque arms in the end.
I tried a few outback roads west of Mt Bryan but the corrugations are horrendous, not much fun. As you know we can dodge potholes and rocks but corrugations covered in bull dust, yuk.
I am glad I put some thought into the build as I have confidence nothing will break, touch wood. If it does, theres plenty of Road Trains here that would strap me to the bull bar no worries. Been there done that. Truckies are great they know their winds so move all the way over so much so its overkill but I love their support., idiots in shoe box cars are a worry.
I ride with eyes in the back of my head and if theres more than one, I just pull over, wait then crank it up to 60 and wonder what they are thinking when I emerge in the side view mirror pronto!
