Both battery packs measure about 27.5V * after charging and then sitting for about 3 hours before testing.

The E-Zip's rack has a tendency to bend in shipping so be prepared to do a little body work with a two foot board placed diagonally through the rack to bend it so the packs fit snug, but not too tight. Each pack needs a periodic (every week at least) examination of the electrical contacts and cleaning them with your fingernail generally suffices. Also, the bottom bracket has a tendency to loosen and it should be checked about every couple of weeks and tightened as necessary to protect the bearings. BTW, the bearings are well packed with grease from the manufacturer and with care an owner shouldn't need to worry about them for the first year of operation.

* On average, the bike has probably been ridden about every other day for about 7-8 miles over the past 6 months.

Also, the bike will probably be ridden daily throughout the summer so we're hoping that the original batteries last through September, but I doubt it. Maybe, I'll post another update around September on the condition of the bike and their batteries.
