    Triangle battery advice

    I have an ibera triangle bag but it's just not big enough. It's great for tools and stuff but not that big battery. I would think it'd be tough to find a bag tough enough to have 22 lbs. hanging from it and stay connected for long. I was also considering a box, maybe some sort of pelican-like...

    Triangle battery advice

    Hi guys, I was hit a few months ago by an older lady crossing a bike path in a hurry to go shopping. :? Luckily I wasn't that hurt but the bike was totaled. As I work it out with the insurance company (who knows when that will end) I'm thinking I may go ahead and purchase a candidate for my...

    Calculating calories

    Hi guys, I'm sure this has been talked about but my search wasn't yielding what I was after so a link or something would be great if we already have a thread on here. Otherwise I'm looking for a good way to accurately measure the amount of calories I burn to and from work on my e-bike. I have a...

    Getting HOT

    Thanks guys. From the battery the wire is thicker AWG (not sure exactly what size) and short, probably only 3-4 in. and it doesn't seem to be a problem. The wire from the connection to the plug (that the controller plugs into) is thinner and longer, probably a size down AWG from the batt cable...

    Getting HOT

    Great thanks for the info, I'll definitely lose the fuse. The wire harness also has a fuse and it's easier to get to (winds up in the side pocket of my battery bag) so even if I lose this one I'll still have one in addition to the BMS like you said, so I should be covered. I'll let you know how...

    Getting HOT

    Sure I can solder them together. Will that help with my heat issue? When I read what you wrote it made me wonder if I had a bad solder job and that's why it was overheating (in addition to it being over insulated by the foam). If there's any truth to that then it should get a bit better when I...

    Getting HOT

    Hi guys, I have a wire harness that's getting very hot. Today on the ride in to work I smelled something burning and zipped open my battery bag and saw that it had started melting a bit of the foam I keep around the sides. Obviously the harness was getting insulated and trapping the heat so I'm...

    Fuel gauge for LiFePO4 batts

    I'm sure this has been answered already but was having trouble finding a thread. I'd like to make some sort of rudimentary fuel gauge for my LiFePO4. To start I'd just like to check it when I get to work in the mornings or get home in the evenings and just using a multimeter would be a fine...

    Hub motor grinding sound

    Yeah your problem definitely sounds worse than mine, I feel a bit of resistance when I stop and just rotate the wheel, but I don't notice it much riding. I ride on the streets exclusively nowadays and nearly always am going 25+. I purchased mine through mega also. Let us know how your...

    Hub motor grinding sound

    The thread you referenced was mine and you indeed captured the noise a lot better than I ever could. It's the same motor and same exact sound, I suspect our issues are probably the same (I have a front hub motor if that's interesting). I also had the same experience, it would begin rubbing 15-20...

    E-bike Haters - Why do so many people miss the point?

    The blogger seems like an idiot, I read some of his other posts. Blogs I prefer tell a story or offer information or insight, this guy just likes to bitch and cry. I remember some dude on a bike (he was with a buddy, they are always with a buddy when they're dicks) yelling something but had my...

    How can I build a 30mph e-bike?

    I have a yescom (or equivalent) front wheel motor 1000W with 48v 20ah battery. I go 12.5 miles @ 25-35 mph give or take to work one way and charge at work and come back home. I had to come back home without charging one day (not fun :roll:) and estimate I got about 6-7 or so miles before the bms...

    1000w yesusa hub motor and have questions

    Yeah, wow. Before I had my extra chargers my one and only charger had a problem and left me pedaling home with 40+ lbs. extra weight. My clothes were drenched in sweat when I got home. I so appreciate that kickass power, especially when it's taken away from me. :cry:

    E-Bike Pricing question?

    I had very little knowledge when I built my bike and you really don't need much. I have the 48v / 1000W front wheel DD hub yescom kit. I didn't use the rack, grips and the hand brakes from the kit as I had my own alternatives, but everything else from the kit I'm still currently using. I've been...

    36v 30ah vs 48v 20ah for range

    When I was first shopping for my components I ran some figures in my head on how much range I could squeeze out if I took it easy and went a certain speed during certain conditions. Yeah, that all went out the window when I rode it for the first time. Now the faster the better. I can't lie...

    GREAT Commute This AM!

    I have a Gary Fisher too, an old hard-tail Tassajara. It's a pretty light mtb that I converted and it's been pretty awesome, granted it's my first so I have nothing to compare it to ebike-wise. Actually it's my first bike I've had since out of the parent's home, it's about 20 years so I'd guess...

    Fat noob wants advice.

    Awesome to read your story, glad it worked out! Not that you need it anymore but I was going to add that I'm around 220 and ride 25 miles roundtrip to work every day I can. I use a 48v 20ah battery, it's not technically a ping (I don't think) but it's pretty much the same. The range is good. I...

    N00b, second ebike build, want to get it right this time

    I agree, I've been checking out craigslist in my area and lots of good bikes for sale for relatively cheap

    need a quicker startup procedure...

    2 pairs of socks ... And I agree, some sort of wool socks would be better than cotton. I'm sporting the basket pedals that came with my bike and some sort of booties / shoe covers might alleviate the wool / multiple sock business altogether. If I really want to go redneck I could cut out and...

    EBike Apparel: Jackets Trousers Gloves etc.

    Yeah I can relate to that. I was thinking about twisting my throttle up some so when at full throttle my thumb would be behind the bar. Barring that I may add some sort of custom extra thumb protection, maybe get a cheapo knit pair of gloves and cut the thumb out or something. Haven't decided

    need a quicker startup procedure...

    I'm a newb still and only have experience with LiFePO4 so far. My controller's bolted on to where the vertical water bottle would go with some padding in between it and the frame to minimize vibrations. The battery is just on the rear rack, I can undo the bungees and bring the battery inside if...

    N00b, second ebike build, want to get it right this time

    Only thing I would add is recommending 48v 20ah. I've heeded the threads on here stating that it's better to get more than you think you'll need and I'm glad I did. This goes double if you plan on riding a lot in the winter. The weight diff between 15 and 20ah probably isn't going to be...

    48v 20ah LiFePO4 charger advice

    I popped another fuse or two after discovering that the fuses were the only problem to my chargers (the ping's fuses were still good though, something else must've happened to that one). I'm wondering if the order in which I'm plugging in my charger is what's popping the fuses? I always plug the...

    48v 20ah LiFePO4 charger advice

    I'm not sure why I keep blowing fuses but that does seem to be the consistent problem. I plug the charger into the wall first, then the charger into the battery. I've blown them both at home as well as at work. I do plug them into power strips / extension cords if that's interesting. I made a...
