Frequently Asked Questions

What is the adjustable handlebar feature on the MotoTec Demon?
The Demon's handlebars can be repositioned forward or backward on the stem without tools. This accommodates riders as they grow taller over multiple seasons — rather than buying a new bike when a child outgrows the reach, you reposition the bars to a longer reach. It also allows different body positions for different riding styles: forward for more aggressive trail riding, back for a more upright comfortable position.
What colours does the MotoTec Demon come in?
The Demon is available in five colours: Blue, Green, Orange, Purple, and White. All colours use the same specifications — the choice is purely aesthetic. At 53 lbs and 14-mile range from the 36V 8Ah lithium battery, the Demon is sized for riders aged 13 and above up to 150 lbs.
How does the key-selectable speed lock work on the MotoTec Demon?
The Demon has three key-selectable speed modes: 5 mph, 10 mph, and 16 mph. The physical key controls the maximum available speed — the child cannot exceed the ceiling you set without the key. As the rider demonstrates competence and safety awareness, you can progress them to a higher ceiling. The variable twist-grip throttle gives full control within each mode.
