    My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

    Justin - this is so awesome! Thanks for providing a continual source of inspiration :) Like you I was skeptical on solar panels with ebikes. However, as you're proving, the efficiency now seems high enough that ebike + solar is a viable possibility. Also, kudos for the human aspect to this...

    Beta tests sold as products

    Hey Joey, Your thoughts echo my own. I have been mulling around what I can do in this regard. I was thinking that E+ also is US made, though their website doesn't actually say that... so maybe not. But I do hope that more of the production moves back here... we need the jobs ... and the...

    Beta tests sold as products

    Hey OneWay, The issue with the eZee is that the mfg specified that this controller is capable of dual volt usage 36v/48v. ALL standard LiFePO4 batteries (16-cell) charge up to 58V then discharge down to ~46-48V during use. So if you go out and buy a "48V LiFePO4" and hook it up to your 36v/48v...

    Hey, It's great that you've had a good experience and become an enthusiast! It is true that some people are lucky out of the gate and have virtually no problems. I'd say about 60% of the time that is the case, though less so with brand new products. The trouble is the other 40% (not a precise...

    I'm glad to see I'm not alone in being concerned about this. I have a few thoughts: - regarding software and beta testing, I see where you're coming from amberwolf. In my day job, I run a group of 12 software developers who are building next generation tools for analysis of biological data...

    Wow, thanks for the heads up. I don't have time these days to read much of the forums, but I'm glad you pointed out this one about GoldenMotors out to me. I will be exercising some significant caution and diligence.

    Hi ecowheelz, It is great to see some others out there who value customer service. I agree that it is critical to interact with a smile and just keep trying to fix problems as they arise. That has worked for many of our customers, who ended up being happy despite hiccups along the way. But...

    Thank you for the nice words. Just yesterday, we ordered a new GoldenMotor "Magic Pie" for initial testing. We'll be testing it for months before we consider selling them. The marketing hype looks great... but what will the reality be? An integrated controller sounds great, until you have to...

    Hey ES people: I popped in here the other day and started reading the BMC 1000W thread, though I didn't get far because something else came up. But I got far enough to confirm what I already thought... that it is a BETA product. Just like many other products that have been pushed out before...

    Yes, when I wrote the thing about testing, I almost deleted it for this reason. But here's the thing - those manufacturers don't seem to have effectively communicated to the DOT and others about the differences with these cells. And to my knowledge, they don't post their test results on...

    There are a few other things we can do as a community. 1. Join the light electric vehicle association. I have an email from them today, indicating they are going to take this issue on. Individual membership is $25, and I believe that will be money very well spent by representing us and...

    I have also done further reading since posting. I think there is confusion stemming from the fact that there are multiple rulings with distinct dates. The2007 ruling seems to be in full effect, and in that ruling, a "large" battery must be shipped as Class 9 Hazmat, and have UN 38.3 testing...

    GTA, you're conflating the other thread with this one. In the other thread, we are talking about risks to passengers on planes. In this thread, we are talking about shipping batteries from seller to buyer, which can be done (and is often done) by ground transport. Please cool it with the...

    Yes, this hits the nail on the head... while there is a subset of the population with the skills and time to assemble packs from tool batteries, this e-bike and EV technology will not ever become more widespread if it requires skills that only 1% or less of the population have. And as of yet...

    I do wish Dave were to be right. But the fact that I know someone who is being fined over this tells me he may not be. The DOT seem serious about enforcing it, at least as far as any air transport goes (into or out of US). I haven't yet heard of any enforcement related to ground shipping...

    What are rules for international flight + Ebike Lifepo4

    The person who is on the receiving end of this incident does not want it made public, and I agreed not to divulge it. Plus I had thought you had read the $50,000 fine thread, where it was mentioned. My apologies for making that assumption and causing confusion. The only thing I'll repeat...

    What are rules for international flight + Ebike Lifepo4

    I don't often take the tone of my last few posts except when the matter is quite serious. This one is. While you can probably get away with this using the suggestions the other posters made, I am trying to simply inform you of the consequences if you do not escape notice. There are $50k fines...

    What are rules for international flight + Ebike Lifepo4

    Just above you said the limit was 300wh, and I clarified exactly what that limit came from and how it is technically defined. The limit is not actually 300wh, as I stated before (but for most purposes, it is close to that). 3.7V is not the voltage of LiFePO4. It would apply, however, to...

    Opinions on Nicads and NIMH.......

    Hi Matt, If you are reconfiguring NiMH or NiCd packs for shiping, those shouldn't be a problem. But if you are reconfiguring Lithium packs, I understand why... :( Regarding the subject of this thread, we also distribute the same NiCd packs that ebikes.ca has, and they have held up well for...

    Hi, The intended tone was of panic because that original letter was written to a group of other e-bike dealers and battery sellers I know. They tend to be an individualistic lot who don't like working together towards any common goal. But tackling the issue is going to take concerted effort...

    Saying things like: Is picking a fight. Now, as to the actual facts: If you read the actual letter of the DOT ruling on the matter, it says 25g is DEFINED AS 0.3g per Ah of cells, or "about 300wh". In actual fact, the letter of the ruling is 25g, which is less than 9 cells and more than 8...

    What are rules for international flight + Ebike Lifepo4

    I don't know why you're trying to pick a fight by saying things like "You don't get it." From the same government link you posted, it states 25 grams ELC is equal to a 10Ah 24V battery (8 cells of 10Ah) maximum, as I posted in the other thread. Why are you trying to pick a fight, when you...

    What are rules for international flight + Ebike Lifepo4

    Hi Based on what I've read about the rules, I wouldn't try it. The rules are very specific about Li-Ion batteries of any type, you cannot bring more than a total of "25 grams" worth of rechargable lithium battery on an airplane, period (even carry on). The fines are stiff if you're found in...

    Hi Thanks for clarifying. Yes, I had thought of this idea - packaging and shipping smaller batteries separately, that can be chained together series or parallel. However, this would present many logistical difficulties for both sellers and end-consumers, particularly if things don't work...

    Lithium Batteries Shipping Rules Discussions

    John, This is a great idea, but unfortunately I think it is DOA. There are two issues: 1) If you fully discharge a brand new LiFEPO4 cell, it is likely to shorten its lifespan 2) The concerns over lithium batteries are based on runaway lithium fires, which are particularly bad in the...
