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.
