Maintenance

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.

    Excellent!

      it seems that at the current rate of 11 cents per Kwh that I’m looking at about $77 a battery for the electricity to recharge it 700 times which is it’s suggested lifespan.
      .
      I’m beginning to look into light weight solar to recharge two batteries & all my other gear in a span of 7 hours of midday Sun. Then I can ride out a battery in the afternoon/evening & another in the morning. That should get me about 100 miles a day across level land & 40 miles a day in some of the most rugged terrain.

        You’ve got it all figured out. Yet the mileage seems a little low to be usable. When I used to ride (pure human powered 10 speed) we did the 60 mile run to Sea Isle City in about 3.5 hours. We had planned to go cross country eventually but at 100 miles/day we’d have added weeks or more to the trip. It turned into a pipe dream anyway. Harry went to jail and I got married.

          That’s with current battery tech, & the 40 miles on two batteries is a dismal estimate that I hope I never see. I could get more than 100 miles on flat land but, I will be loaded heavy & have to consider that I may lose 1/3 of the range I currently enjoy to the weight of luggage.

            Anyway I spoke out of turn. We had figured on 150 to 180 miles per day depending on the terrain but the 240 mile run to Pittsburgh took us just over 3 days. The mountains made all the difference. And your way you’re not killing yourself. Besides I like your approach.

              I’m hoping for an average 100 mile or better day. I may change my mind in favor of lower mileage days with more meeting new people.

              Yeah. That’s the way to do it.

              That’s part of the purpose of the trip, to help me take a big breath & slow the eFF down.

        oops sorry that should be about $42 for 700 charges & up to 35,000 miles. It’s not a Kwh per charge but, there is a loss of energy I will pay for, about 80% of the energy that I buy gets into the battery.

    Oh, crap, are you talking about a motorcycle? If so, you did all that…………mechanic stuff……….yourself? If so, hats off, you go! What? I’m a girl who drives a minivan, but, I grew up surrounded by men doing the shit I now pay horrendous amounts of money to have done to my vehicle. In my defense, I know what an idiot light is.

      It’s not a “motor” cycle, it’s an eBike. Legally it’s a bicycle, in Virginia I can ride as fast as the speed limit as long as I am pedaling. It has no throttle, it responds to pressure on the crank. Not only did I do all the maintenance myself I built the bike from a list of parts that I compiled myself. The motor kit came as one unit from the manufacturer (battery, motor, controller, wire harness, display & controls (includes the bottom bracket which the cranks attach to because that’s the part that activates the motor), the frame came as a frame & fork without a headset (bearings & a set of cups to hold them that fit between frame & fork), I chose parts based 1st on quality, then nation of origin. I don’t like the guy who makes Surly frames (he’s named his company well) but, he’s built some of if not the toughest frames available at production prices instead of some custom $$$ frame set. This is a prototype & I was mostly concerned with keeping costs under control while building something I can take to Electric Vehicle shows & bicycle trade shows as well as ride hard, that it is a little heavier than it needs to be just means my mileage estimates are that much more conservative.

    We should use less energy as we are in short of money and we have less resources as well that is why we should be careful and that is also explained in custom research papers that we need to know it better the condition I which our countries in and how much they are suffering.
