Have you ever created something yourself, then critically analyzed it and thought, “It’s not bad, but I’ll change A, B, and C about it next time” right afterward? It doesn’t even have to be mechanical; In fact, this kind of thinking can apply to anyone who makes things themselves.

Anyway, if that’s you, you’ll especially appreciate the work that went into this build 3C Mini Works Out of Ohio. The guy is having a lot of fun doing EV conversions on the smallest Hondas, from Rukus to Grom; And wouldn’t you know it, every time he makes something new, he learns something new for the next time.

to get ready for this year Smoky Mountain Small Bore RallyHe had to do some extra special preparation with all the things he learned along the way. Friends, this is an EV Honda Grom, but it is no EV-swapped Honda Grom. Oh no. Instead, it’s an EV-swapped Honda Grom with an extremely powerful hub-mounted motor, and we know it because they put it on the dyno and Wow. callback again from a christmas story “You’ll take your eye out, kid!” Not there. Absolutely Correct here. But does this somehow seem spiritually accurate? IDEK, and I digress.

To be perfectly clear, what you see in this video is a condensed time-lapse of the months and months of work that 3C did to bring this project to life. This is an overview of the total project as it came together, from laser-etching the Steady Garage-sourced powder-coated plate on the rear hub, to 3D printing a bunch of parts he wanted to make himself. To that end, there are even some really cool little spindle adapters they have 3D printed to make it easier to use your Pit Bull rear stand to securely hold the bike in place for transport. Really, it’s the little things that make all the difference.

If you want to see any part of this build in more depth, visit 3C Mini Works’ YouTube channel and Peep dedicated playlists. You’ll get more detailed information about each part, including how 3C strengthened the suspension and built a steel battery box to handle the extra weight of the heckin’ chunker of long-range batteries. The strong, fully adjustable suspension, Brembo brakes, and a motor that produces 63 horsepower and over 400 pound-feet of torque at the rear wheel (dyno tested, there’s even a whole video on it in that playlist) are the epitome of wild work.

There’s even a test-ride video, so you can see and hear what this thing is like on the road. Although it makes some very jetson-As noisy as it is on the table and on the dyno, it’s incredibly quiet on the road thanks to that hub-mounted motor. Hub motor means there is no drivetrain and no chain; All the wires leading to the controller, which is located above the battery just ahead of the seat, are neatly hidden inside the swingarm.

Man, this thing looks fun. Would you try it if you could? I know I would, but what about you? Tell us about it in the comments!
