Today I did my 1000 mile maintenance.
I took the wheels off & re torqued the axel nuts.
I took off the battery rack & cleaned the frame, I unwrapped the wires & cables then restrapped them all with new cable ties after cleaning the mount & the cables.
Inspections revealed no damage to any cables & no slipage at the torque support on the motor.
I changed the transmission oil in my internally geared hub, ran clean oil through it twice to get it as clean as possible for it's 1st service call.
The motor will take this type of safety inspection every 500 miles from now on & the transmission every 3000 miles (or 2 years).
Rode 20 miles today & burned 2 cents worth of electricity, the cost per mile for the bike has now dipped below $5. At 5000 miles the bike's cost per mile will be a little over $1 per mile By 10,000 miles it should be down to less than 51 cents a mile. The battery is rated to 28-35,000 miles depending on how much assistance I use over all. My goal is to get about 7500 miles or more a year on the bike, so in 4-5 years I expect to buy another $400-$600 battery.
