• BMX bikes are a unique frame geometry, essentially forgoing all travel efficiency for maneuverability and sturdiness. • For how much abuse these bikes are designed to take, these are all good tradeoffs. • But it turns out that these bikes also have an exceptionally low center of gravity, which could make them useful for drag racing,provided they’re given a suitably large electric motor and a few minor frame modifications. • The project began as a fun weekend project for friends [Sam Barker] and [Tom Stanton]. • They had a 20″ BMX wheel with a massive integrated hub motor that seemed to be begging to be put onto a BMX bike that they had on hand. • After hooking up a 72V, 20Ah battery to it they were quickly zipping around the driveway, but the short wheelbase on the bike was bottlenecking its maximum performace because the bike would wheelie under high throttle.

  • A pair of friends, Sam Barker and Tom Stanton, converted a BMX bike into a low‑gravity drag racer by mounting a 20‑inch wheel with a large integrated hub motor and a 72 V, 20 Ah battery. The original short wheelbase caused frequent wheelies, so they welded an extended frame that also provided space for the battery and reduced over‑steer. To add stopping power, they fitted a caliper from a penny‑farthing. The result is a street‑illegal, high‑performance electric BMX that can be used for drag racing. The project highlights DIY electric‑bike modifications and the growing trend of YouTube creators turning hobby builds into content.
