Ah, cool, wish I knew they made a 24x2.6, I just bought a 24 x 2.35 pickup. For cargobike with the a DM01 mid drive (Now stopped working). That’s cool if you think you can run smaller wheels on a 29er full sus, I though pedal struck and bottom bracket clearance might be an issue, but prob not too bad with fatter tiresIF I had it to do over again, I'd go with a Leaf 4T motor in a 24" rim and I'd run a Schwalbe Pick-Up 24x2.6" tire. This is a link to the tire: Schwalbe Pick-Up | Super Defense | Black-Reflex | 26x2.15 | Addix E | 11159144 You have to scroll down a little bit because the 24x2.6" size is not shown in the list at the top right of the page. I know they make them because I have one. As for other 24" tires...the Maxxis Hookworm 24x2.5" is a pretty good option.
With disc brakes, you can use any size wheel you want. Using a frame that came with 29" wheels is going to keep me in the disc brake camp as opposed to rim brakes because I do not know of an easy way to run rim brakes when I install a 24" or a 26" wheel in the frame that came with 29" wheels. My current bike is a Schwinn Axum 29er and I am currently running 26" wheels. I'll eventually lace my motor in a 24" rim and run it in the rear. I did switch to shorter crank arms (92mm) so I won't have pedal strikes every time I turn...with 92mm crank arms, I don't pedal much
The 24" wheel will work in a frame that came with 26", 27.5", or 29" wheels but there are a few things you'll need to watch out for:
I would go with a 52v/14s battery if it is legal in your area. 52v/14s is 58.8v when fully charged and will give you a little more speed, a little more capacity/range, and more power with less heat than a lower voltage.
I’m back to planning an ebike build for my wife. I’m not sure whether she’ll like it or will stick to it, but I’m also building it with the possibility that I may ride it if she loses interest; so easy to modify for higher performance later. So far I’m set on 60v and 20” rear hub, on a 24” Specialized Hot Rock frame, with front and rear hydraulic brakes (to help with arthritis) and have been scoping out Craigslist.
My question is, is the 2000W 60v motor sold by Leaf the same as the 1500W? I noticed that the performance graph they use in the description is for the 1500w motor. I’ve been assuming that for modeling in the Grin simulator, for the (wife’s) low power mode (20A) and a high power mode (60A) adjusting kv for a 4T wind, but want to make sure that’s a safe assumption.

I’m too lazy to lace, so I plan on ordering the 20” wide rim, and likely run one thing like Super Moto X tires.
Most likely. I think they just have two or three stator widths they relabel for view count/size listing. I just picked up the "2kw 60v" (see pictures reposted earlier) and it's the same internal configuration as the thread's original 1500w motor. Apparently they've just refined their winding process a bit over the years.
.My wife is shorter and growing shorter, so the lower the better. I’m going the lazy route with the wheel already radially laced. I was originally going to go with a BMX frame, but there’s more room to spread out on the small mtb frame, in case I end up riding it.
Thanks. I read your build thread. It does look like the same motor. Nice to know that they have an extra conductor for a heat sensor, even without ordering the option. My 1500w had a temp sensor, but not compatible with the CA so I swapped it out.
Were those 3/8" (9.52mm) or 10mm drop outs?
"shorter and growing shorter", I can relate...I have lost about 1.5" in the past 10 years.
.I'm looking at certain model years of the 24" Specialized Hot Rock and Rip Rock, converted to 20", before bikes started hydroforming the tubes making them all swoopy and hard to mount stuff on. Both come with short travel suspension forks and rear disc brake mounts. I'm going to see if I can fit a LG 21700 16S4P pack under the downtube that should be good for 35A, if going to 20" provides sufficient clearance. Looking at the simulator, it looks like running at 20A would provide good power but still tame (wife mode). 40A+ and it becomes a beast. I'm planning on mounted the controller under a rear rack, and probably some saddle bags to semi-hide the motor. I have to see the bike to find out how big a front chainring I can mount, but on the rear I've scoped out either a 6 speed freewheel (13T), or a single speed (12T). I'll probably go with the latter and get rid of all the derailleur stuff. For the beast mode, I'll parallel two 5Ah 8S 65C lipos and limit to around 60A for fun. I'll use a CA to manage things and have an simple dial to turn power up or down."shorter and growing shorter", I can relate...I have lost about 1.5" in the past 10 years.
Do you have a donor bike yet? I was looking at the Walmart web site for bikes that came with 24" wheels and the biggest issue is whether my 14s6p triangle shaped battery will fit in the frame. The 24" Schwinn Axum appeared to be a reasonable option but I need to find the frame sizes for all the bikes I am considering since they should give me a good idea whether my battery will fit

I'll verify next time I have the motor off, but fairly certain it's a bog-standard HG Spline M at 35mm. It has an HG31 8speed 11-34t on it, and don't recall having to use any spacers on it.
