Voltaic Flying Fox 20″ 48V Youth Electric Dirt Bike Overview
The Voltaic Flying Fox 20-inch 48V is the top-of-the-range youth electric dirt bike in Voltaic’s lineup, built for experienced young riders aged 10 to 15 who are ready for genuine performance. A 750W motor powered by a 48V battery delivers a 26 mph top speed – the highest in the Voltaic range. Adjustable front forks with 80mm of travel, an adjustable hydraulic rear shock with lockout, two-piston hydraulic disc brakes, and three power modes create a full-specification off-road bike that takes young riders seriously. Available in Black and Blue.
Who Is This Bike For?
The Flying Fox 20-inch 48V is for experienced young riders who have progressed through smaller bikes and are ready for the top-tier youth performance that the 48V platform provides. Recommended for ages 10 to 15 with a maximum rider weight of 155 lbs, this is the bike for a teenager who has mastered the fundamentals and wants a genuinely challenging, rewarding off-road experience rather than a starter bike with limited ceiling.

48V vs 36V: Why Voltage Matters
The Flying Fox 20-inch is available in both 36V and 48V configurations, and the voltage difference has a real impact on performance. Higher voltage delivers more electrical energy per unit of current, which means the 48V motor receives more power than a 36V motor of the same wattage rating under identical conditions. In practice this translates to better acceleration, more consistent performance at higher speeds, better hill climbing under load, and a more stable power delivery across the full charge cycle as the battery depletes. For experienced riders who push the bike hard on varied off-road terrain, the 48V platform delivers a noticeably more capable experience than the 36V alternative.
Hydraulic Disc Brakes: Why They Matter on a Youth Bike
The choice to equip the Flying Fox with two-piston hydraulic disc brakes rather than mechanical disc or drum alternatives is a deliberate safety investment. Hydraulic disc brakes provide more consistent, progressive stopping power than mechanical alternatives because they do not require cable tension adjustment as cables stretch with use. The hydraulic system maintains consistent feel and performance throughout the service life of the brake pads, and provides the rider with a more intuitive braking response – applying more force produces proportionally more stopping power in a way that mechanical systems can struggle to deliver. For a bike capable of 26 mph in the hands of a young rider, brake quality is not a place to economise.
Kids Electric Dirt Bike Safety
Electric dirt bikes for children and youth require appropriate safety equipment and supervision on every outing. A properly fitted, certified helmet is absolutely non-negotiable – no child should ride any two-wheeled vehicle without one. Full-face helmets provide more protection than open-face alternatives and are the appropriate choice for any dirt bike riding where falls are a possibility. Knee pads, elbow pads, and wrist guards provide meaningful protection for the types of falls young riders experience during the learning process. Chest and back protectors are advisable for older riders on higher-powered models like the Flying Fox series.
Supervision is essential for new riders and strongly recommended for all children under 10 regardless of experience level. Adults should be present during early sessions to provide guidance on throttle control, braking technique, and hazard awareness. Young riders should start in enclosed, level areas where the full risk environment can be controlled before progressing to open fields, trails, and more varied terrain.
Speed modes are a critical safety tool on Voltaic’s three-mode bikes. Always start new riders in the lowest speed mode and allow them to develop genuine confidence and control before advancing to higher modes. The urge to give a child access to maximum performance too quickly is one of the most common errors parents make with powered ride-on vehicles. The progression from low to medium to high mode should be measured in sessions and skill development, not hours.
Check local regulations regarding electric dirt bike use in your area. Many trails, parks, and recreational areas have specific rules about motorised vehicles. Private land with appropriate space and surface is often the ideal environment for younger riders. Always ensure your child understands and follows the rules of whichever environment they are riding in.
Choosing the Right Voltaic Bike for Your Child
The Voltaic lineup is structured as a deliberate progression path. The 12-inch Cub is the entry point for very young riders or children with no prior balance bike experience – the non-powered mode allows skill development before electric power is introduced. The 16-inch Lion is the next step for riders who have outgrown the Cub or come to their first bike with some balance bike experience and a larger frame. The Lion Pro upgrades the 16-inch platform with higher-output motor and suspension for more capable riders who have mastered the basics and want more challenge.
The Flying Fox series addresses the youth and teenage market with genuine off-road performance. The 16-inch 36V model covers ages 6 to 9 at up to 19 mph. The 18-inch 36V model covers ages 8 to 12 at 19 mph with a larger wheel for more confident handling. The 20-inch 36V model covers ages 8 to 15 at 22 mph with the largest wheel size for the most stable, capable ride. And the 20-inch 48V model is the top of the range at 26 mph with higher voltage for more power and range, suited for experienced riders aged 10 to 15.
When in doubt about sizing, err on the side of the smaller model. A child can always grow into a larger bike more safely than they can compensate for a bike that is too large and powerful for their current skills.

About Voltaic
Voltaic is a kids and youth electric dirt bike brand built around a simple mission: give young riders a genuine, properly engineered electric dirt bike that progresses alongside their skills and confidence. Their lineup spans the entry-level 12-inch Cub for the youngest beginners through to the 20-inch Flying Fox 48V for experienced teenage riders who want genuine performance. Every bike in the range is built with age-appropriate speed limits, hydraulic brakes, and proper suspension that reflect Voltaic’s understanding that a kids bike is not a scaled-down adult bike – it needs to be right-sized in every specification for the rider using it.
Voltaic’s Flying Fox series uses hydraulic disc brakes, adjustable front forks with 80mm of travel, and adjustable hydraulic rear shocks with lockout – the kind of component quality typically found on adult mountain bikes, applied to youth sizes where it matters most for safety and riding confidence. Their Lion series and Cub are designed as a progression path that develops skills sequentially, building the balance, braking, and throttle control that young riders need before advancing to larger platforms.
The Voltaic Progression Path
Voltaic designs their lineup as a deliberate skill development progression that takes young riders from their first powered experience through to genuine off-road performance. Understanding this path helps parents make the right initial choice and plan the natural next steps as their child grows.
The Cub at 12 inches is the starting point for very young or completely inexperienced riders. Its non-powered mode means a child’s first experience on the bike can be completely without motor power, developing balance and braking skills before any speed is involved. When the child has developed basic confidence, the electric mode introduces a gentle, manageable first experience of powered riding.
The Lion at 16 inches is for riders with some experience who have outgrown the Cub’s size or who come to the hobby with balance bike experience already. The 18-inch inseam minimum ensures proper fit for safe control. The Lion Pro upgrades the 16-inch platform with more powerful motor and suspension for riders who have mastered the Lion and want more challenge without yet being sized for a larger wheel.
The Flying Fox series covers the youth performance segment across three wheel sizes: 16 inches for ages 6 to 9, 18 inches for ages 8 to 12, and 20 inches for ages 8 to 15. The 20-inch platform is available in both 36V (22 mph) and 48V (26 mph) specifications, with the 48V recommended for experienced riders aged 10 to 15 who are ready for the top-tier performance the Voltaic range offers.
When choosing between these platforms, rider size and skill level matter more than age alone. Some 8-year-olds are physically and developmentally ready for the Flying Fox 18-inch; others are better matched to the Lion. The best indicator is watching the child ride their current bike: if they can consistently maintain control at full speed, stop smoothly from speed, and navigate mild terrain obstacles with confidence, they are ready to progress. If they are still developing these fundamentals, advancing to a more powerful platform is premature regardless of age.
Electric Dirt Bike Maintenance for Parents
Kids electric dirt bikes require light but consistent maintenance to stay reliable and safe. Before each riding session, check tyre pressure and inspect the bike visually for loose bolts, worn brake pads, or any damage from previous sessions. Check that the brakes engage properly and provide firm resistance – spongy or weak hydraulic brakes may need bleeding and should be inspected by someone with bicycle mechanical experience before the session continues.
After each session, wipe the bike clean of dirt and mud, paying particular attention to the brake rotors, suspension components, and battery contacts. Dirt and grit that accumulates in these areas accelerates wear and can affect performance over time. Periodically check that suspension pivot bolts are tight and that the handlebars, stem, and seat are secure at their correct adjustments.
Battery care follows the standard lithium battery principles: charge after each session rather than waiting for full depletion, store at 60 to 80 percent charge for periods of non-use, and avoid storing the bike in extreme heat or cold. Electric Bikes Paradise is available to advise on any specific maintenance questions for Voltaic bikes.
