[GRMNT] decided to bring his grandpa’s beautiful road bike into the future by making a sleeper e-bike conversion.

Going into the project, [GRMNT] didn’t really know what he was working with, but it turned out grandpa had good taste and was rocking a Bianchi. No stovepipe bike boom stuff here, only high quality Tange steel. After cleaning off the years of grime, it was time to rebuild a second-hand Bafang mid-drive electric motor for the electric boost for the ride.

We really like the custom solenoid-powered display that [GRMNT] built into the handlebars for an excellent electromechanical readout of the battery charge. Coupled with the hand-built battery pack inside a leather case and hidden motor actuation button, this build looks slick without screaming e-bike.

We’ve covered some other conversions in the past including this one using an electric skateboard motor or this plug-and-play kit. If you’d rather power things with your bike, you’ll like this hack that can make everything bike powered.

Asus unveiled a compact e-bike conversion kit called Oxiis E250G1, a lightweight device that clamps onto your seatpost and adds electric assist to almost any regular bike.
