A homebuilt machine that converts the small Honda Grom to electric power and produces unbelievable output via a hub motor is generating buzz. Despite its low-slung, close-to-the-ground stance, the output is on another level entirely, and RideApart describes it as 'a love letter to garage ingenuity.' It's a machine where an individual builder pushed a balance that no production bike would dare attempt.

An electrified Grom pulling insane power out of a hub motor — this is interesting precisely because it comes out of a garage build. A hub motor simplifies the drivetrain but carries the drawback of increased unsprung weight. This is a machine built with full awareness of that trade-off. A work where passion outweighs the data. I want to root for experiments like this.

This is probably a bike built entirely for the hobbyist thrill rather than practicality, so you're unlikely to see it on public roads.

A balance that production bikes don't touch probably means some safety margin's been thrown out too.

A low-slung body with off-the-charts output—the balance between center of gravity and gyroscopic effect seems genuinely dangerous.

With a hub motor, the heavy mass concentrates right at the wheel, so the gyroscopic effect itself should be quite strong.

Being a hub-motor setup means it's built directly into the wheel rather than chain-driven.

Calling it a love letter to garage ingenuity is way too tasteful a way to put it.

An individual's garage build getting picked up by media is proof it's been recognized as genuine craftsmanship.
