Jim I already have a rear pack with the stock batteries in it. But if you want to sell your old one I will take it. That way i can build the lipo pack and not be down while doing it. PM or email me the details alton.keel@gmail.com thx, Alton

Same here. I use 30-32 wh/mi based on the cycle analyst. I put a rock shox air shock on mine and now the rear doesn't hop as much. The steep rake angle makes it handle quick. Many have complained but I like it. It is a lot like my trials bike. You definitely have to pay attention. The up side...

I'm getting 33 mph on a flat surface @ 31 amps with the stock primary and secondary in series with my crytsalyte motor and a 72v 40a controller. Looking forward to switching to lipo poly batteries.

I replaced the pos rear shock with a 6.5 inch rock shox air shock and that made the rear suspension really work well. It made the unloaded ride high a bit taller and I had to extend the stand but when loaded with me sitting on it the ride height is about the same.

Actually if i can get two in the tube and four in the second rear pack that will give me 33 amp hours :mrgreen:

Great Idea, I'll think I'll give that a try. Right now I'm using the original batteries in the frame tube and the aux pack wired in series for 72 volts. As soon as they wear out or I get impatient I'm going to replace them with the zippy packs. I have to current limit to around 30 amps now to...

I have done a motor and controller upgrade on my a2b and was wondering if these are the batteries that you used in the rear battery case? ZIPPY Compact 5800mAh 10S 25C Long Lipo Pack I am going to be ordering a set soon.

Ok the conversion is done and i've figured out how to display pictures. Before: After: Every thing went well with one exception. I assumed that the phase wire connector was configured for the motor as i got them from the same vendor. But alas no .., I twisted the throttle and a few poles...

I have a question and excuse me if it's somewhere i haven't found . Is the reason that the high current controllers are going to more fets that they are reaching the thermal limits of the fet package or of the heat sinks that they are putting on them. I know that the parallel fets drop the...

I was planning to current limit the controller to about 25 amps till I have a battery replacement worked out. But at 72v thats twice the power. I have a tidal power project planned for those other two motors but that's a different forum. On the battery front I plan to have full HVS and LVS cell...

I'm sure it was the controller, The first one lost a phase then died, but I was in the middle of a 47cc two stroke kmx trike at the time and just wanted my ride back. I'm in a hotel in College Park, MD now and i don't have the machine tools to play with the stock motors here but I will have two...

Hello all, I am new to this forum and this is my first electric bicycle project. I've built many internal combustion trikes, racing karts, etc but this is my first electric project. I bought this Metro to use around town and have left it mostly stock up to this point. I'm on motor number three...
