    Old tricycle build. Looking for advice. Mac motor?

    I'm looking to turn this old granny trike into an etrike. 24 inch wheels. Got it for cheap and it has nice steel 100mm front forks to work with so I figured it would be an easy project. (bright don't kill me yellow) Most of my driving around town is flat, but I still want good pulling power...

    Skin vs Pavement?

    Pavement wins. Took a bad angle into a corner at the same time an oncoming speeding SUV was dead smack in the middle of the road. So I forcibly dumped myself into the corner vs taking a wide turn into the grill of the SUV. I was in shorts and a T-shirt. I skid for a good distance and I...

    Can I still use Regen with batteries in series?

    2 Pings: 48-15 and 1 24-15 connected in series directly (no diodes) Independent BMS on each battery. Can regen braking still be used? Or will current be dumped into just 1 battery? Btw , bike works again, thanks for the help on troubleshooting the BMS. Joined the 38.9 mph club (so...

    Great bag for Ping V2.5 24v 15ah battery

    http://www.walmart.com/ip/Plano-Small-Tackle-Bag-Waistpack/16351070 Plano 3380, enough room for the BMS to breath on top and for some padding to fit between the bag and battery. Plenty of options for wiring and mounting. Fits into a smaller triangle and isn't wide enough to impede peddling...

    Battery click sound, now showing far too low of voltage.

    Today I received a brand new 24volt battery from ping, got it hooked up in series along with 2 diodes 48v ping with less than 100 cycles on it. Everything worked great. Reading 81 volts on the CA. Right where it should based on the measurements before hooking everything up. Let the wheel...

    Candy is dandy but liquor is quicker. Upgrading to 35mph

    I'm currently waiting for my new spokes from Jhr, and this idle time takes my mind to a faster place. My commuter has done fantastic in its initial season, aside from my constant mishaps, melted connections, flat tires, busted rim. Meh. Nothing I can't handle (says the man about to lace his...

    Dishing Wheels, Drilling Rims, and Picking Vendors oh my!

    I hit a pot hole(more like sink hole) which bent my stock rear 9C 26'' rim. Also blew up my tire and tube, but that is another issue entirely. I have the newer 9C with the flat faces. Non-disc, with a 7 speed freewheel. I have been looking at the Alex DM24 , 36 hole rim in 26" , only...

    2806, almost no power, horrible grinding sound, with video

    ob15i0NhtkE Took the bike out for work this morning and made it about 100 yards before this started happening. That scratching/grinding sound is constant when I sit on the bike and additionally, I am getting "almost" no power from the motor now. Also, in this video, I had to kick start the...

    58.82 amp spike on a 15ah ping

    YIKES :shock: I had 22 amps set at max in CA, and normally I get spikes of 23-24 accelerating. However, a potentially BMS triggering spike of this magnitude certainly isn't expected or wanted. It was just a quick spike, a few times, and strangely it was with 0 throttle. I'm not sure if...

    Anderson Power Poles Melted together.

    48v15ah Ping Ebikes 25amp controller set up matched to a 9c I had been experiencing some problems with short out the past couple weeks, prime suspect was at the discharge wires, the metal contacts looked corroded. I figured I'd just deal with it because anderson crimpers are pricey. Well...

    Freedom ThickSlick tires.

    http://shop.freedombicycle.com/thickslick.html I have the 26 in 2.0 tire. Unexpectedly, the spokes on my 9c were lose , all of them. I was running the stock knob tire on my diamondback and decided that while I had the wheel off to tighten spokes I should switch to a highly durable road...

    Regenerative Braking and Ping 48v 15ah concerns

    File this under things I didn't give enough initial consideration. PingBattery.com lists the max charging current as Charging Current: <5 Amps I have been using regenerative braking with my ebike for the past 2 days. Never after a full charge, but after a mile into most of my trips. I looked...

    I just got my ping battery, no lights from the bms.

    I have the two wires connected coming out of the BMS. No lights When I plug the XLR connector into the charger for 30 seconds No lights When I plug the discharge wires into the bike motor. The motor runs Cycle Analyst shows 54 volts (and negative amps?) (calibration?) No lights. 48v 15ah...

    9C 2806 vs MAC 8T

    :Newb: 50v20ah Rear Mac 8T Build.

    The previous build was a 9CRDD 1965 schwinn typhoon, unfortunately due to the brake being linked to the hub, I had no way of stopping without welding something to the frame, which I didn't want to do. Or I had to go FDD, which I really don't want to do. Different bike means new priorities...
