Frequently Asked Questions

Why is a chain-driven motor better for a kids' dirt bike than a hub motor?

Hub motors are excellent for flat pavement, but they can struggle to provide enough torque when climbing grassy inclines or tracking through soft dirt paths. The MX125 utilizes an 100-watt high-torque motor paired with a traditional mechanical chain drive. This reduction-gear setup multiplies the rotational torque delivered to the rear tire, allowing younger riders to tackle backyard terrain and dirt trails with much greater power and ease.

How does the speed control switch work, and where is it located?

The MX125 features a hidden parent-controlled high/low speed toggle switch. For riders who are just learning to balance, parents can lock the bike into Low Speed Mode, which limits the motor's output to a safe 5 MPH. Once your child masters steering and braking, flipping the switch over to High Speed Mode unbinds the controller to achieve the default 8 MPH top velocity.

What are the benefits of a sealed lead-acid (SLA) battery for this age group?

Sealed lead-acid battery technology is incredibly durable, highly stable, and exceptionally safe for younger riders. Unlike delicate lithium cells, SLA batteries are highly resilient against the bumps, impacts, and vibrations that come with off-road learning. Additionally, they provide a smooth, steady current that allows for an impressive run time of up to 80 minutes in Low Speed Mode.

Does the MX125 require any maintenance out of the box?

The MX125 arrives mostly assembled with the complex electrical wiring, fairings, and braking lines fully completed at the factory. You will simply need to attach the handlebars, fully inflate the 12” pneumatic tires to their proper riding pressure, and connect the included charger to top off the 12V battery system before your child's first ride.
