In this instructional video, Warren Harper reveals a DIY method to hack and derestrict Shimano-powered electric bikes, effectively removing the standard 18 miles per hour motor assistance limitation. The technique involves repositioning the speed sensor from the wheel to the chainstay and attaching a small magnet to the crank arm, which tricks the bike’s computer into believing the rider is moving slower than actual speed. Using a Commencal Meta Power e-mountain bike as an example, Harper demonstrates how to perform the modification with minimal tools – including electrical tape, an Allen wrench, and a specialized magnet. The hack is presented as a non-destructive method that can be easily reversed, potentially allowing riders to maintain motor assistance at higher speeds. While the video provides a step-by-step guide, it also emphasizes the importance of understanding local regulations and potential legal implications of modifying an e-bike’s speed restrictions.
