I have a couple friends that got to Race this Hare Scrambles in an All Electric Class. I was not there, so this is just a collection of the info I got, so please correct things that I may have in error, but I am so proud of the DIY riders for there showing and excited in the fact that we, all...

What are the dimensions of your battery, and what bike are you putting this in?

Dave, I told you that Amorge can make almost any size, but there are some limitations. The width of 6.10" is maybe doable, send it off to Amorge, and they will let you know if the can and will give you a price. Usually they stack 2 rows of cells in that direction, so that is why I think why...

You should be able to find newer YZ donor bikes, I have heard that the motors like to scatter themselves a little too often, and it isn't cheap to rebuild a motor that scatters. But Suzuki and Kawasaki provide a great base to build on, I just don't have any experience with them. Amorge can...

Hey Eric, welcome to the Forum. I'll give you my 2 cents worth, and you may find other opinions. My two favorite bikes to build are the 2014-2018 YZF250F and YZ450F. This has plenty of space for the battery, and the suspension can be really refined. My second choice is a 2018-2022 KTM...

"The X-Pro class will feature a series of two heats leading to a final Kicker Audio Clash event, where the top riders on both ICE and electric bikes will go head-to-head."...

I posted this voltage converter, and did not dive deep enough into it at first. If you go to Amazon and search 120VAC to 240VAC Voltage converters, you will find a real variety. Price for 5000W for $96 to $189. They all seem to be the same basic unit. (You can determine by the weight the...

Yes building the battery is tough. You make mockups and it all fits, and the final product is always a little too tight. I am finding that Amorge can build to very exact specs for the outside dimensions of the battery box. They can tell you how many cells will fit, and they make a nice...

Theo, The resistor is in parallel with the master on/off Switch. I use the switch instead of a relay. So when you plug in the battery to the bike with the switch off, the 1K resistor will fill the Capacitors in the controller, with no arc, in a few seconds. So from then on there are no arcs...

Dave, this was a 2023 Honda CRF, and it came with a Titanium tank, and I just couldn't bare to cut it up. So I found this Carbon Fiber tank cover. You can see the battery comes all the way up The power switch on this one is for Dual battery system, but you can get both single and Dual battery...

Dave, I tried some battery combinations in the Honda bike I have here. Just some test fittings. If you go back above, and look at IMG6656, the side view of the Honda. you can see the space below the battery in front of the motor, I can fit a 6 cell by 8 cell pack in there. Then I made another...

Dave, A couple of ideas. The shape of the battery you proposed will be difficult to fit. Bob Casper in his CRF 250 build built 2 separate batteries. 20S6P x 2 for multiple reasons. One to fit in the CRF frame, two for the battery heat, and three for faster charging. Now there could be space...

Dave, Bayodome has some valid comments, and some good ideas. I agree with not weakening the frames whenever possible. I think these cuts are minimal. But they do compromise the frames strength. But since you have a clean slate, lets look at his choices. On his YZ250F ebike, he is using the...

I have a 6.25x8.25x13" Amorge in a 2005 450CRF frame with only slight mods. I heard that the 250 frame is narrower

Yes you can ask for it and they will do both. I just received a battery from them, with Open discharge, but i did not spec 40A Discharge, so it only has 20A charge. Here are a couple of pictures of the KTM battery I just got. This is a 20S12P Molicel P42A cells, Open Discharge, and Charge...

I don't want to bad mouth Eon Lithium , but we have bought a few batteries from them, and have not been real happy. Bob knows Raymond there at EON Lithium real well, and has one of his batteries, and I put one in one of my customers bikes, and were not real keen on them. The battery you are...

No I’m not. I wanted to go but cannot. Austin at Electro and company are going to be there. It should be very interesting

I have just finished a 2005 CRF450 and I used 1/4" (6mm) 6061 aluminum. Lithium-King .com drew them up and had them waterjetted for me. But There is a offset needed for certain frames. Here is a picture (PDF) of the mounts superimposed on a Honda frame. Use all the mounts on the motor...

I believe the throttle used on the Stark is the same one used on the ALTA, it is the Hirschman Throttle. You could use it, but is has a large diameter and it makes it hard to actuate the front brake on the smaller bikes, and a lot of front brake master cylinders. There are ways around it and...
