    Rize Liberty – What a mess for a $15.00 design oversight.

    All suggestions look good and merit looking into somewhat. I will need to do some research through the fall to see the efforts needed behind the different options out there. I will need to pay particular to the electrical and how to connect / retrofit to the existing connections if I don't go...

    Rize Liberty – What a mess for a $15.00 design oversight.

    Why limit your self to a Reention Dorado 48V 21ah Battery? There are plenty of other options out there. :D :bolt: Guess I was just showing my ignorance to this technology. Make and model is not important to me. I'm more interested in the plug and play function rather than retrofitting...

    Rize Liberty – What a mess for a $15.00 design oversight.

    I don’t think I will need to worry about “configuring” a new battery. The Reention Dorado 48V 21ah Battery seems to be rather common as far as replacement batteries. Easily found on eBay for something like $1200. On Amazon it’s a good $850 plus. Keep in mind these are Canadian dollars. That...

    Rize Liberty – What a mess for a $15.00 design oversight.

    Managed to bring up the lower cell pack to 4.0 V . Reconnected the BMS harness and charged the battery for 24 hrs. First row of figures is freshly off the charger. The second row was after a 12.1 km ride. Mainly pedal assist. Black & Green = 4.16 V = 3.84 V Green & yellow = 4.15 V = 3.84 V...

    Rize Liberty – What a mess for a $15.00 design oversight.

    I will likely go the way of buying a battery but I need to make absolutely sure my shutdown issue is the battery. I'm still not sure it is not something else at this point. As I'm typing, I have a 5V charger (with a 100W light bulb) charging the 3.4V cell pack. I want to bring it up to 4.0 V...

    Rize Liberty – What a mess for a $15.00 design oversight.

    Thanks ebuilder, appreciate the suggestion and probably would have went that route 30 years ago…heck even 10. Would have loved one of these back then to push the limits a little and have enough power left over to bring me back. I’ve always enjoyed new projects , challenges and lost causes...

    Rize Liberty – What a mess for a $15.00 design oversight.

    In for a penny, in for a pound I guess. Opened it up. It was easy enough to slide out. Harness pins are way too small to charge 4.0V with anything I have in house. So I will see if I can charge it on the pack somewhere by chasing the wires. Guess I'll take the winter to slowly see if I can...

    Rize Liberty – What a mess for a $15.00 design oversight.

    Boy you guys are way ahead me on diagnostics, cause vs. symptoms but I believe I get the gist of it. Well at least I hope I do. Was opting for charging just the group of 3.6V but the point of why that group is at 3.6V to begin with and will likely degrade again , somehow makes sense to me. SO I...

    Rize Liberty – What a mess for a $15.00 design oversight.

    The harness not seated well was me. I was trying the BMS reset thing I read about. I had just placed it lightly back for the picture. It’s snap in good now. Not sure if I understood the direction properly but this is what I got. (Polarity was the same all the way through. Starting from the...

    Rize Liberty – What a mess for a $15.00 design oversight.

    I believe 53.4 - 53.6 Volt is as high as it's gone with an overnight charge. I can try leaving the charger for longer if that would help? I didn't think that one volt short of 54.6 meant a big deal for a 2-3 year old battery. Regardless, below is the pic asked for. Well i believe this is what...

    Rize Liberty – What a mess for a $15.00 design oversight.

    Thanks again for the detailed guidance. It is definitely a good reference for me. I have a little experience with ebikes as I have done it once before. As they say, I know enough to be dangerous. My issue here was the symptom of shutting down. I have no experience on what this could...

    Wow, thanks for all the input everyone, really appreciate it. I will get to the pics requested in due time. Unfortunately life is getting in the way of FUN right now. Older parents to take care of and stuff. As to the term “MacGyver-ing”, I was just dating myself for lack of a better word...

    Rize Liberty – What a mess for a $15.00 design oversight.

    Opened up the battery easy enough, 4 screws. Tried the reset thing by disconnect the harness but not much changed. Actually no….. This time the power still cuts off but the display remains on. So the system still has power but the throttle and PAS has no affect until I shut it off and on...

    Rize Liberty – What a mess for a $15.00 design oversight.

    I think your old saying hits the “nail” right on the head , pardon the pun :D . In my experience this is called a single point critical failure and is usually avoided like a plague in all designs? Would we design electrical systems without fuses? Not sure if Rize realizes what kind of a hit a...

    Rize Liberty – What a mess for a $15.00 design oversight.

    *** PICS AT THE END *** Picked up a 2020 Rize liberty bike a month ago from one of our local “for sale” sites. It was advertized with a damaged motor harness. Turns out the damage was much more extensive and all, in my opinion, could have been avoided with a $10-$15 Torque arm. I have little...

    Looking for Bafang motor cable.

    Thank you very much. Really appreciate it. Waiting on anther source but I believe I will end up getting this one after all. Two questions if I may. 1 - was it tight to pull through the shaft? Any major issues? 2 - in your pic, it looks like the small green and yellow wires are reverse from...

    Looking for Bafang motor cable.

    Hi, I recently got a good deal a Rize Liberty e-bike with a 48v bafang G062. 750 watt hub motor that needs the cable replaced because it's ripped. Not sure why but I cannot seem to find where to buy the motor cable. Found the following but it’s to short for me. https://ebikes.ca/l1019-m.html...

    A2B problem

    Sorry for the delay in responding, was away for a few days Thanks for the suggestions, I will look into them as soon I get a chance. Hoping it’s a brake cut off switch, it’ll make my $350 (CDN) investment worthwhile. I was under the impression that the controller was inside the main frame as...

    A2B problem

    Hey everyone. Picked up an A2B gen 2 from a bike shop. It was their floor show model for 2 years since the owner purchased the shop. He doesn’t know how long the previous owner had it for. If anyone knows how to determine the year of the bike, I would appreciate it. The bike is “new” but they...

    A2B battery help needed

    If you tell me how to measure the capacity I can give it a try. All I can say is that it seems to last rather long under no load. In order to have access to the battery while it’s connect to the bike and draining, I have the bike upside down with the throttle locked to the ½ position and the...

    A2B battery help needed

    It official, the main A battery is ALIVE. Not sure for how long but it definitely held its charge (41.5 volts) overnight and throughout the day today. I began charging through the BMS once it went over 30 volts and the smart charger took over until the light went green. All cell packs are at...

    A2B battery help needed

    Main frame battery: For the main frame battery, i switched to the bikes 36V charger and placed a few bulbs in series giving me around 110ma. Much faster rate of charge. About 1 volt for every 20-30 mins or so. Doesn’t seem to hold at the voltage that I stop at when I need to leave the house for...

    A2B battery help needed

    Will take a look at the strips kdog but I would think that if this is the case for me, the motor would not work as well when bypassing the BMS as I did using the terminals on Pic B Battery BMS 2: Regardless, will use your advise as a preventative measure and see what I can do to secure them...
