    Strava for E-bikes?

    Its an old thread but I have same question really. I've hunted through the menus on Strava and can see that a ride can be changed to an e-bike ride but cannot see how to default future uploads (from Cyclemeter) to e-bike rides. You can set up your equipment but I can't see how you can set it to...

    Where is a great place to find quality 18650 cells cheap?

    No, brand new unused cells direct from the Polish factory ... they make for Samsung and Panasonic and Sanyo the brands he is able to get from this factory vary. Tumich has sold a lot to Endless Sphere friends - the freight from Poland takes a while but air-freight of batteries is becoming more...

    Kiwis, step in and discuss your eBike experiences in NZ

    I know solder is NOT the way to go ... but that's what I did (I have no access to a spot welder). I first built a battery from used/old laptop batteries... but had massive sag and soldering was imperfect so I started again with new cells - I saw on here that others had some success with solder...

    Kiwis, step in and discuss your eBike experiences in NZ

    I live in Upper Hutt and Kapiti. I did buy a volto bike $1800 off trade me ... it was a rear hub 350 watt 35km/hr machine and was great on the flat ... but in Wellington area we have hills... LOTS of hills and without a real sweat up going over 400 metre high Moonshine Hill was a stretch ...

    Im not going to bother with a BMS

    1) The BMS gives you no visibility as to where the individual cells are at - you need the 1-8 cell LEDs to give you voltages otherwise the battery is a black box. 2) There is no balancing going on with a BMS if the pack is not fully charged - we don't want to fully charge to maximise the life...

    Daily commute vid with new BBSHD

    I am also commuting on a BBSHD - on nice sunny days only... chased a rabbit the other day! https://www.youtube.com/watch?v=_L-g-3q41Qc I got a BBS02 first but it failed after only a couple of rides < 100 km - happily I was refunded and purchased a BBSHD - it has not missed a beat :-)

    Bafang BBS02 Vendor & Reliability Poll

    Paul at EM3EV stood by me with a full refund and even return shipping for my failed BBS02. He was grizzly - he wanted me to pull it apart and mess with it given the cost of shipping ... but the motor had only been a few kms and really not even stressed, it was even a despec'd 18amp controller...

    Which display do you prefer to use with BBSHD?

    I've had a 965 the DC-10 and now the colour one ... I do like the voltage display for 52v pack and the power output reading. What would be spectacular would be a trip power meter... how many watt hours for that trip?.... Sadly I still have to have a watt meter in my pack to figure that out -...

    Do you use a helmet mirror?

    Further experimentation ... the helmet mirror was small and there was some wobble too so I tried the mirrors that stick out the end of the handlebars - more firmly attached. The best yet for me http://www.ebay.com.au/itm/281891766382?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT...

    New Bafang Crank-Drives

    Don't believe so ... but the new colour display will display voltage if you choose custom battery (or the analogue bars for those with 48v) - so at least you know where it is at. Getting below 3.2v x 14s ~ 45v is BAD!

    BMS mystery - how does it actually work?

    Curious about this part too... most I suspect will now be charging to 80% with BMS - so, does this mean we are no longer balancing our cells as they are never charged to 100% so the BMS is never having a crack at discharging the over voltage cells?

    How To Wire a 12V Brake Light and Turn Signals

    I can't see how I can connect any of the wires incorrectly as each plug has a locator to ensure it is the correct way around. However, I am wondering with only one brake sensor connected perhaps this causes this anomaly. With one of the sensor plugs disconnected completely and the other...

    How To Wire a 12V Brake Light and Turn Signals

    and the other give away was when I got on it to ride it the motor doesn't go until I brake :-) I have obviously connected something incorrectly when reassembling after my crash!!

    How To Wire a 12V Brake Light and Turn Signals

    I have weird one ... I had a crash and one of the brake levers and the brake sensor was a casualty. I have only one sensor now as a result until a replacement turns up. I've disconnected the remnants of the bust sensor - so just one connected. However, now when I turn on the controller the...

    How To Wire a 12V Brake Light and Turn Signals

    Mission accomplished - I need to tidy the mounting as I have the relay in a GT power meter box with the power meter removed.... lots of cable ties and cables too... but it works!!! Thanks for making this possible for me :-) I used the opto-coupler in this post...

    How To Wire a 12V Brake Light and Turn Signals

    I want the brake light to work off either brake, I guess I could feed from both brake sensors to the opto-coupler relay ... I am using the reed switches with hydraulic disk brakes connected to each of the brake sensor cables. I am thinking that I could avoid separate connections from each ebrake...

    Bafang BBSHD, 1000W, 68mm-120mm BB

    I am amazed at how efficient this is ... I have a GT Power meter on a 14S pack charged to 57 volts - my commute is 30.6kms I am looking at 4.58 AmpHrs - 5.7Amp Hours worst case. OR between 235 Watt Hours and 293 Watt Hours. That is 9.6 Watt hours per km or 15.3 per mile. I am on a lightish...

    Yeah I saw that one too where he finally got it going .. using the same BBS02 wiring harness wire colours for the 8 pin connector. Kepler is another very clever man!

    How To Wire a 12V Brake Light and Turn Signals

    OK - checking local suppliers... what about http://www.surplustronics.co.nz/products/7593-1-channel-12v-relay-module-coupling-optocoupler I am a bit confused about the voltages - we have a 5 volt supply from the brake cut-off reed switch and we wish to drive 12 volt light. So don't we need a 5...

    Or this one ? http://www.ebay.com.au/itm/12V-1-Channel-Relay-Module-with-Optocoupler-H-L-High-Level-Triger-f-Arduino-New-/261452317454?hash=item3cdfc5c30e looks like it has a jumper to set to LOW trigger - but doesn't have the same connections as your diagram!
