Yedoo Scooter project Dual motor long Range

This was my first dual-motor project—huge thanks to the Grin team for answering all my questions! I built these two e-scooters with high fun, portability (bike rack compatible), and long-range capabilities in mind. With dual 21700 battery packs, I achieved a tested range of about 90 km on steep hills roads, even at 2°C.

They’re also prepped for the solar trailer I’ve been designing! Each scooter will be equipped with a detachable 200-watt solar trailer, extending the range to approximately 150 km during 5–6 hours of sunny riding. This could be even more on flatter terrain.

The front motor is a Grin All-Axle Slow Wind, powered by a Phaserunner V6, while the rear motor is an SAW20 with a 74mm axle width, capped at 500 watts for that extra push on the many steep hills in Quebec's northern regions. As shown in the picture, I can pull my kid in the Thule full-suspension trailer (about 50 pounds total) while maintaining a solid 22 km/h up an 8% grade hill.

More details to come as I fine-tune things—stay tuned! Cheers!
