Building my motorized bike was both challenging and incredibly rewarding. I started by picking out a sturdy mountain bike frame, knowing it would need to handle the power and weight of a 69cc 2-stroke engine. After securing the engine to the frame, I carefully aligned the chain and checked each mounting point to ensure everything was tight and vibration-resistant. When I finished, I took it for a test ride, and the results were even better than I’d hoped—it easily hit speeds over 40 km/h, and the torque was strong enough to carry two riders. Fine-tuning each component was worth the effort, and the thrill of riding something I built myself was unmatched.
