    Charger Recommendations for 48V Lithium Battery (~20Ah)

    I got my bike and charger out and charged it up. I went to charge the battery last night and couldn't find the charger. I also realized I no longer have a spare. I loaned it out and the person moved. I think I put it someplace safe and out of harms way. I still have some capacity left, but I...

    Used EV Car Batteries for E bikes, Trikes and Such???

    I've been wondering if old batteries for electric cars, which run at much higher voltages, might at the end of their automotive life have enough power in them to use for some smaller EV. Maybe not a bike because the car batteries are bigger and too bulky for a bike. I was reading about Leaf...

    Low Profile Cable Glands/Cable Entry

    I need to build a thin battery case to mount to a spot on a frame. There is plenty of room in some places, pretty tight others. The place where the wires come out the the pack are in a pretty tight area. The pretty common cable glands, especially for a larger cable like coming from the battery...

    3D Printed Battery Case & XT90F Panel Mount

    I'm going to be building a new bike in a few months and have found an stl file for a triangular battery case. I'll probably have to adapt it some, but is is a start. I also use XT90 connectors and would like to continue to do so. I have found some commercially available female XT60 panel mount...

    Custom Triangle Bag Makers

    I know there used to be individuals or small businesses that would make custom triangle bags for battery packs for the frame you have. Triangle packs and bags were much less common then though. There are many manufactured ones that are pretty adaptable now. However, I will be mounting a...

    Single Motor Hall Sensor Wire as Speed Signal

    I have seen some mentions of this in other posts about Hall sensors, but I haven't found a post just about this. Some of the other comments make sense and others don't so I thought I'd do a post just on this subject. I am setting up an older ebike that has a good motor with a new controller...

    Oval Rubber Grommets

    Have an older out of business ebike frame where the wires were run partially through the frame. They entered and exited through some oval rubber grommets. The dimensions of the opening in the frame are about: 4.5-5.0mm (~0.18") x 31.2mm (1-1/4") x 19.9mm (3/4"). The frame is from and e-moto...

    Step Through Conversion

    I'd like to look into converting a step through crank forward like a Townie to electric. I have an electric now and probably most of those parts could be used. I'd prefer to mount a battery pack in the lower down tube, but I don't know if how much space there is between that and the other tube...

    Sources for E-bike Frames

    I currently have a Bafang mid-drive with the batteries in the triangle pack. It works good. At the moment however it is very hard for me to get on and off it. I have both back and knee problems that need to get taken care of. However, I will continue to get older, my battery pack will need to...

    5V Out on BBSHD Board

    I can't find the thread or the part I'm looking for, but some time ago I asked if there was a 5V pinout somewhere on the Bafang BBSHD controller board somewhere. Somebody posted a picture of it with the potting removed and an arrow marking where there was 5V, but very low amperage available. I...

    Folding Solar Charger

    I searched and didn't find anything like this, but, it seems like someone would have already looked into this. I was wondering if some sort of folding solar charger would be something that is available or something you could make. I'm thinking of it as something you would stow away and have as...

    Electrical and Lighting Question - Specific to EV Global?

    I have a 36 volt EVG ebike. I bought it new. Not too long after I got it I modified the headlight housing so I could use an MR16 LED array to replace the halogen that came with it. Everything seemed to work fine. I noticed last year that when I had my headlight on it would start flashing...

    DIY SLA Battery Pack?

    I have an old 36V EV Global ebike. After EV Global went out of business, the manufacturer of the batteries ceased production of them. I remember reading about how 2D printing could really change the way you would go about replacing an obsolete part in the future. The example I read about was...

    Brake Levers with Switches

    I have a Crystalyte controller that has a brake inhibit pigtail. It has a red lead (+5V) a black lead and a green lead. I see that the Crystalyte brake levers seem to have hall effect sensors as each has three leads coming from each lever. It is my understanding that you can also make this...

    Fuses

    I'm getting ready to assemble a new ebike. I will be using a 48V 20 AH Ping Battery with a Crystalyte 40 A controller and Phoenix motor. I'd like to add a fuse to the circuit but am not sure what size to use. I have read elsewhere to use one rated 1.5 times the controller's rating. That...

    Crystalyte Controllers and Brake Levers

    I thought I heard that C-lyte controllers can work with brake levers that either have a conventional switch of a Hall effect switch. Is this true. I seem to have the Hall effect kind and would like to use some with a conventional switch so I can trip a relay to have a brake light. Can I do...
