This Friday turns out to be no good for me making it into the city, but hopefully next time. Still have yet to come across another ebiker out here in the western suburbs.

Been pretty happy with the Michelin Pilot Spot 2.3" tires. My rear one is almost bald after 1,600 miles, but I like the performance and looks. Only 1 slow leaking flat in that time despite riding through plenty of broken glass that accumulates on the under-used bike paths around here...

I might be able to do next Friday. Out in the Tysons Area for work, but I could take a field trip into the city.

Putting the wraps on version 2.0 Based on an older Kona Kikapu 26" FS frame that will hopefully handle the rough bike trails around here that were tough on my hardtail. Also reconfigured the Ping battery & mount so that the whole thing setup is only 4" at it's widest point, down from 6", so...

Getting from Dulles to the W&OD is definitely going to be your biggest challenge, that area has mostly non-existent shoulders and fast heavy traffic. Might be worth finding alternative transportation to get closer to the bike trail and save the stress. Other than that it sounds like a great...

Correct, all 16 groups get above 3.65v and the BMS brings all the higher ones back down to around 3.6v. Before I made the modification last week it was a very balanced pack with about 70 cycles. My concern is that the cells are briefly getting up to 3.95v-4.0v which I believe is too high for...

So the procedure initially seemed like a success, but a problem has cropped up now after charging,balancing,lightly discharging the pack. The 4p cell groups (4&5) on either side of the split are charging faster than the rest of the pack, hitting 3.8-3.9v before the charger shuts down. The BMS...

Thanks for the tip about removing some solder, I didn't think there was a tab folded over in the middle of the board but after looking more closely it looks like there is one or more there. Was able to melt and remove a little of the solder last night, but I don't think my 40w iron is up to the...

Thinking of taking the plunge and attempting to split one of my Ping batteries in half for v2.0 of my ebike. I want to keep the battery almost entirely in the front-triangle, but this time keep it narrow enough (4" instead of 6") that I can pedal comfortably and the only way to do that is going...

Nice looking bike, too bad it slipped through my DC Craigslist filter and you got it instead of me :)

Rebuilt the rear wheel with 13/14g spokes w/ washers and an Alex Supra-D welded downhill rim. Hopefully it proves to be stronger than the stock one. Also made a frame mounted battery holder to move the 22lb battery from the rear rack to the front triangle. Riveted & epoxied together...

Data from the first 33 cycles of my Ping battery. Pleased to see wh/mile averaging only 29.7 vs the ebike.ca simulator which put it over 40.

Looks like it's not a good week for spokes in DC. I had just watched your video earlier today and then get home to find 3 broken spokes. http://endless-sphere.com/forums/viewtopic.php?f=6&t=39854#p582438

Rolled over 700 miles today and started hearing a new sound coming from the rear wheel. Didn't see anything wrong at first, and just assumed it was the rear brake rotor making more noise that usual. 30 miles later I make it home and take a closer look to find 3 broken spokes. Each one spaced...

Had to up the gearing so I could pedal at 30+mph. Couldn't find a suitable 4 bolt chainring or 5 bolt crankset that was both compatible with my bottom bracket and/or would clear the wide mountain bike chainstays. So I went with this accident waiting to happen. It's held up for 200 miles so...
