Electric kick scooter build

[EmAre]

I have a 26”x2” wheel with motor which I intend to use on the scooter in the attached photo. In my research I could find no good reason to not have the large wheel on the back. The scooter doesn’t have to be portable or light which seem to be the primary reasons for small wheels on scooters.
I have a 40 volt battery that will fit in the water bottle clip on the front post.
Would appreciate any first hand knowlege on the idea. Thanks

I haven’t done this type of modification. The first hurdle, I see, will be to figure out to safely extend the rear “arms” to accommodate the larger wheel size. But maybe you already have planned for that?

Those aren't the only reasons. Small wheels are much more nimble and in case of a hub drive, accelerate much quicker than larger ones. They also allow for shorter wheelbases which is again a desirable trait. They also don't go fast enough to reap the benefits the larger wheels bring.

If you want a vehicle that's not portable or light, with large wheels, that can go faster - why not build a moped/motorcycle instead?

slaphappy, I plan to modify the rear triangle of a standard bike since it has the seat post which will give me the option of adding a seat if needed.

You almost need a ridiculously large wheel with a hub if you are only using 40v. You won’t get much RPM from voltage that low. Can def work if you’re not wanting stellar performance. I’d suggest the “mini” Kelly controllers with a frame that small. They work really well. Might as well buy a 72v controller. Then you can bump voltage up later if you want. RC lipos work really well for small builds. Can handle alot more amps than what you are planning to run.
