    MAC 6T Suddenly has Regen??!

    Well, all of a sudden my MAC 6T has regen. I had the bike on the stand and noticed it wasn't freewheeling properly. Then when spinning the cranks to check out the freewheel...I noticed the CA lighting up with no battery connected. I'm guessing this is the clutch. I'll open it up soon...

    Kona Coilair Supreme - MAC 6T Build

    Another Hubmotor Commuter Build (yawn): Well I managed to run my first build for about 6 months before starting on number two. I’ll start by saying there was absolutely nothing wrong with the first build (link). I was getting a solid 25 Wh/mile, at an average speed of 25 mph for an 18 mile...

    Opinions on weak LiPo cell?

    I've got a new Hobby King Turnigy 20c 6s 5000mah LiPo pack that has a cell (#5) that slowly self discharges. I've cycled about 10 times: 3 on the charger, the rest testing on the bike. After discharge and recharge, the cell might show 20-30mv out of balance with the rest. I'll balance it on...

    New Power Connector on CA

    Not sure if anyone's mentioned the extra power connector on the new Cycle Analyst yet. I just got another CA from eBikes.ca: a large screen DP with speedo. But, this one has an extra power connector on it. I looked in the manuals and saw no mention of it, and the one I bought last year...

    Question on LiPo Cell Failure Mechanisms

    So I've have a couple of HK Turnigy Lipo 6s 3Ah packs fail. But the method of failure has me guessing as to what has happened. In one case, the pack arrived with a missing cell (ERR on the CellLog, 19.25 volts on a 6S pack)...I sent it back to HK. In the second case, the pack tested fine...

    eBike Crash: Wet wooden bridge...

    A few minutes into my commute...a wet wooden boardwalk gave me a little wake up call! The bridge goes through a park called 'Alligator Alley': there's a ton of alligators hanging around because people feed them from the Hampton Inn breakfast buffet across the street. Gators love those shitty...

    New HK Turnigy LiPo Pack Problem: Missing a Cell?

    I've got a problem with a Turnigy 6s 3000mah pack I ordered from Hobby King's US warehouse. I ordered 16 packs..and just finished checking all the cell voltages with a CellLog. One pack reported an error when I hooked up the CellLog. I checked the main pack voltage with a DVM and it read 19.1...
