MotoTec Demon 50cc Kids Dirt Bike vs MotoTec Supermoto 50cc Kids Dirt Bike

Buy the Demon for a young rider who will actually go off-road: it has front and rear disc brakes, a front inverted fork and rear mono shock, and a chromoly frame built to take abuse. Buy the Supermoto for a lighter, lower, street- or hardpack-focused bike for a smaller or older rider, but know it gives up the front brake and all suspension. Owners of both praise the simple pull-start 50cc two-stroke and automatic centrifugal clutch; the Demon's extra hardware is what separates them.

  • Choose the MotoTec Demon if your child rides trails, grass or dirt and you want real suspension and two disc brakes.
  • Choose the MotoTec Supermoto if the rider stays on smooth hardpack or pavement and needs the lowest, lightest 50cc MotoTec makes.

What reviewers say

MotoTec Demon 50cc Kids Dirt Bike

Owners of 50cc mini dirt bikes like this one generally treat them as a step up from toy bikes, praising the real suspension and brakes but noting the upkeep of a two-stroke engine.

What people mention
  • EngineMixedRiders like the torque of the 50cc two-stroke but dislike mixing oil into the fuel.
  • StartingCriticisedPull starting is reliable once tuned but tiring for younger riders with no electric start.
  • BrakesPraisedFront and rear disc brakes are seen as a real safety plus over drum-braked toy bikes.
  • SuspensionPraisedThe inverted fork and rear mono shock handle bumps better than rigid mini bikes.

MotoTec Supermoto 50cc Kids Dirt Bike

Owners of MotoTec's 50cc minis describe them as simple, light and easy for kids to start riding, and the Supermoto's low seat and automatic drive get the same kind of praise. The common complaints are the stiff, unsprung ride and the fuss of mixing fuel.

What people mention
  • Ride comfortCriticisedRiders say the rigid frame and lack of suspension make bumps and ruts feel harsh.
  • WeightPraisedOwners like that it is light enough for a kid to handle and for an adult to lift into a truck.
  • Seat heightPraisedThe low seat is called out as a confidence builder for shorter, newer riders.
  • StartingMixedThe pull start is simple and reliable but takes effort, especially for younger riders.

Questions and answers

Which is better for trail riding?
The Demon. Its front fork, rear shock and knobby tires are made for dirt, and the front disc brake helps on descents. The Supermoto's rigid frame and street-style tires are for smooth ground.
Which is better for a smaller rider?
The Supermoto. Its 21-inch seat height and 37-pound weight let a shorter rider touch the ground and handle the bike. The Demon sits taller.
Is the Supermoto worth stepping up to over the Demon?
It is not a step up in hardware; it is a different bike. Pick it only if you ride hardpack or pavement and value the low seat and light weight over suspension and a front brake.
Which lasts longer?
Both use the same 50cc two-stroke pull-start engine and need the same 25:1 gas-oil mix and upkeep. The Demon's suspension and brakes add parts to maintain, but they also take stress off the frame on rough ground.
Can either be speed-limited for a beginner?
The Demon lists an adjustable throttle limiter. The Supermoto has a variable twist-grip throttle but no limiter in its listed specs, so check before buying for a new rider.
What age are these for?
MotoTec rates the Supermoto for ages 13 and up with a 120 lb max rider. The Demon is marketed as a kids' starter bike; match seat height and weight to your child.
