Notes by ride:
11 Apr '09
My bicycle will turn one year old in a of couple weeks, and today's ride demonstrates that it's as healthy as ever. It even had the power to tow another cyclist three miles to the nearest bike shop so he could repair his broken chain. I'm impressed - two weeks ago, I was getting less than 10 miles per charge. (More on that here)
- The ride begin following a complete overnight charge.
- Start and finish location were the same.
- I unplugged the charger at 11:30 a.m. and reconnected it in at 2:45 p.m. (3 hours 15 minutes later). Green light on charger appeared 4 hours later, and I believe this occurs at roughly 80% charged
- 4 miles involved carrying 15-20 lbs of groceries
- 3 miles involved towing a 160 lb rider on his mountain bike.
- One WideLoader was attached to Xtracycle.
- Road in upright, mountain bike position [ 90% of time] and sitting on Xtracycle Deck and holding onto the seat (slightly more aerodynamic) [10% of time].
