    A2B Metro - www.ultramotor.com - Video Page4

    Can you provide any info on the wiring configuration for the rear battery? I want to replace my 4 year old battery that is down to 60% capacity with a new pack from ElectricRider, but I don't know how to wire it once I cut the cannon connector.. Haven't disassembled the battery pack since I...

    osnpower battery 48v 20ah review

    Lan, The battery suppliers with the best reputations are the ones who deliver reliable products and provide excellent customer support. Price is not the primary mover, believe it or not. Your manufacturing manager should review your ads for accuracy on a periodic basis.. He would know better...

    Don't waste another minute with those Kendas.. they are chard magnets. Many of us have bought these Shinko moped tires and thorn resistant tubes.. So they are 16" motorcycle tires (based on rim size, not 20" bicycle tires based on tire OD)... They seem very durable... 3 months no problems...

    osnpower battery 48v 20ah review

    The OSN ad clearly states "Geniune Made in the USA short tab cells." This is a draw for those who know the USA cells have a better reputation. If they are going to substitute batteries they should at least advise the customer, or just pull their bogus ad...

    osnpower battery 48v 20ah review

    Read this entire thread and admire your patience.... Like every international sale it doesn't matter if you're right and have a point, the onus and the cost falls on you, the customer... Materially misleading the customer is a concern for me.. Even though, as April alleges, the Korean...

    If you're still riding those 3x20" kendas good luck! Shinkos were a huge improvement. Will be interested in what you find for a rear shock replacement.. If you search ES, you'll find some guys went wih a pricey fox air shock which they like....

    Any experience / opinion on Li-NMC packs from HiPowercycles

    LOL... Well you cannot be that crude if you've been able to work those batteries for that long.... There must be a certain amount of attention to detail with these Turnigy's.

    Any experience / opinion on Li-NMC packs from HiPowercycles

    Hobby Lipos are kind of crude.. Cant figure out how to charge the entire 60v pack at once.. If you make a mistake goodbye pack.. And they only last maybe 300 cycles? And the failure rate of new ones seems pretty high...good for racing or playing a round i guess but i want a reliable fast e...

    Thinking about running stock A2B metro 36v with an Allcell

    Guess you could parallel the frame battery and the Allcell to run 40a.. they both are rated 2c http://www.allcelltech.com/images/act/ebike/allcell_36v_ebike.pdf

    Any experience / opinion on Li-NMC packs from HiPowercycles

    Fair enough... Ping is out.. Allcell is about the same price as high power but is a domestic supplier with a 2 year warranty, but no 60v pack. Will checkout cellman thanks

    Thinking about running stock A2B metro 36v with an Allcell

    I have that bike and running the frame battery over 2c doesn't seem like a good idea at all... 20a should be the limit imo. When my 09 A2B motor finally cooks I was thinking about using a MP3.. probably get 25 mph w/36v.. same problem though since the integrated controller is 35a.

    Any experience / opinion on Li-NMC packs from HiPowercycles

    http://www.hi-powercycles.com/product.sc?productId=29&categoryId=5 Expensive $1000 delivered for a 63v 12.5ah LINMC battery pack w/charger. Only weighs 10.6 lbs.. Can fit in a frame easily. They say 700+ cycles... Are there better choices, consider size, cycle life and cost?

    A2B Metro battery

    I received a quote from Alibaba for 150 cells for $560 delivered to USA... That is enough for my primary and secondary battery packs. Has anyone disassembled the in frame pack? Someone told me these batteries were spot welded... What is needed to spot weld these buggers besides the tabs?

    Resurrecting an Ultra Motor A2B Metro with 20S power

    What a great writeup! When my A2B finally quits will definitely keep this in mind. Do you have the wiring diagram on how you had the motor rewired after the internal controller was removed?

    Anyone else getting ebike elbow ???

    If you're doing 35 mph the death grip is understandable... Also sphincter grip! I use Ergo grips from Germany and they relieved wrist and forearm stress.... Concave or Convex depending on how you flip them. There are many different sizes and types... here's one...

    having an electric bike is like being an alien

    That's kind of funny... I get questioned all the time, and let people ride my UltraMotor A2B if they want. Some people accuse me of cheating? Others think it's a great idea esp in the summer heat. I try to tell the naysayers that China has over 100 Million E bikes on the road. They don't relate.
