    Better than the Stark Varg? 76v 90Ah 35kw Dirtbike Build

    I would have to agree with this. I have that setup too. Cable throttle with the TPS sensor thing. It does feel good. I even have an extra throttle box in case it fails. Keep it in my backpack with my emergency tools. Hadda layer down once because of the clibbins and the throttle still worked...

    Better than the Stark Varg? 76v 90Ah 35kw Dirtbike Build

    I'm using a QS10 with 4 gauge. 450A peak. I've never noticed any heat in the cables or the plug. There are very large Anderson connectors like the ones electric forklifts use. Depending on whether or not you plan to remove the battery often, you could put ring terminal lugs directly on the...

    Better than the Stark Varg? 76v 90Ah 35kw Dirtbike Build

    Don't get me wrong my controller does heat up. It's rated for 800 amps though. I'm only using half that and for short bursts. The ND721800 is a giant controller. It has a large aluminum block on the bottom which is in thermal contact with the MOSFETs. It gets hot but not to the point of...

    Better than the Stark Varg? 76v 90Ah 35kw Dirtbike Build

    I have the phase amp setting at 1800. I can't pin the throttle from a dead stop because it has too much torque. It will just wheelie. I feather the throttle so that the front wheel is just about to lift up off the ground and it will pull like that to about 40mph or so before the torque starts to...

    Better than the Stark Varg? 76v 90Ah 35kw Dirtbike Build

    My bike has the qs138 90h water cooled, a 20s10p P42a pack, and the fardriver ND721800. I have the Line amps at 450. I don't get much heat from my battery. Granted it only sees the full 450 under hard acceleration. I get about 8v of sag when I pull the full 450. I used the copper nickel sandwich...

    Joe's E-bike build

    I've never seen anyone play one of those. That's awesome and I loved the song he played at the end! Thanks for putting that link in here it made my day better. That is exactly the method I used. Some of the spokes on the new front wheel were very loose. I tightened them all to what I felt was...

    Joe's E-bike build

    Haven't updated this thread in awhile. The bike still isn't 100% done. It's starting to cool down here and winter will be here soon. I've decided that it's probably best not to try and ride this in the snow. I'll probably put her away for the snowy months. Updates: Made a stronger motor mount...

    Joe's E-bike build

    I put a fardriver nd721800 on the bike. I initially set the line amp setting to 400 amps. The belt stripped and broke when I gave it half throttle. It tore the teeth off. So I replaced the belt and set the tension extremely tight. It was still doing the same thing so I switched to a chain The...

    Joe's E-bike build

    A couple videos of the bike from my backpack strap mounted GoPro. I'm not real good with it yet. The angle kind of sucks at certain points. I kept it around 30mph In the second one because that's as fast as the motorized bicycle(aka the brapsicle) goes. For the record, I don't typically ride...

    Joe's E-bike build

    No video yet. Planning on ordering a GoPro this week. I have the cooling system set up now. The water pump is 12v and runs off a buck converter along with the lights. There's no reservoir although I may end up adding one in the future. It seems to work well this way. The square thing with the...

    Joe's E-bike build

    I started making a cover for the controller. It's made from the drivers side front fender of an 03' LeSabre. Still haven't painted the bike yet. I put a DNM rear shock on it because the other ones were just too soft. The old ones had 250# springs and the new single shock has a 1000# spring. It's...

    Joe's E-bike build

    I got the disc brake on the front Sunday. I test rode it again and it's pretty fast. It's quieter than I expected with the 530 chain. Not loud at all. Got the belt aligned properly. I had an issue with the rear sprocket. I think I forgot to torque down all the bolts because it developed a wobble...

    Joe's E-bike build

    I finished the battery box earlier. Almost. It still needs to be sealed up and I have to modify the cover a little bit so it fits right but it's on the bike now. I made a track so that it sort of slides in from the side and then I latch it in with the two toggle latches. The wire exit isn't...

    Joe's E-bike build

    Got the rest of the battery done this week. The two packs are separated by two layers of heat resistant foam padding with a sheet of fiberglass sandwiched between them. The ends of the packs which will be in contact with the steel housing are covered by 5mm thick silicone sheeting. I have some...
