Thumpstar TSE 12-C

Dealer Price $699 CAD

The TSK141-E has received a complete overhaul for Version 5 adding the much-awaited ELECTRIC START and compression adjustble front forks.

Gone are the days of facing struggles of dealing with issues which are common on many other mini bikes. We have gone back to the drawing board and scratch built a New Frame, Airbox, Linkage Suspension, Hubs and Rims, and much more. This has not only allowed our bikes to become much more strong and reliable, but also gives the rider peace of mind knowing that, no detail has been left untouched.

Our design team has produced a piece of engineering art, the frames are a new Quad Bar which has made them stronger than ever. Along with the frame developments we made space and rigged them with mounts to accommodate our new caged airboxes, this allows a better air filtration system while increasing airflow into the carburetor and in turn more horsepower. A first on pit bikes and minibikes alike, we have scaled down the linkage from the likes of a full size race bike, and fitted it to these smaller sized 140s. The linkage provides a much smoother ride than traditional PDS style suspension which allows for faster cornering, high and low speed adjustments, and increased rider comfort. We have redesigned our hubs and created space for a much heavier duty 20mm rear axle, coupled with stainless spokes and alloy rims, which provide our strongest wheels to date. Check out our description video and the following spec lists to see these upgrades!


TSE 12-C
Sale Type
  • This bike includes Thumpstar's KICK START feature for added safety, which prevents sudden, unexpected starts. (The rider must start the bike in motion or "push off" before the motor activates.) As the rider gains experience and skill, the KICK START feature can be disabled by opening the bottom cover and unplugging the clearly labeled "KICK START" wire.
  • 3-Speed Switch on the bottom of the bike conveniently allows your child to start slow and increase speeds as they gain skill and experience.
  • The Speed Limiter can be disconnected by removing the bottom cover and disconnecting the easily identifiable "Speed Limiter" wire. (Be sure to set the above mentioned Speed Switch on the bottom of the bike back to the SLOW setting until your child is ready for maximum performance!)
  • The Torque Switch can be disconnected by removing the bottom cover and disconnecting the easily identifiable "Torque Switch" wire for maximum starting and hill-climbing power.
  • An Aluminum Frame with Steel Forks makes this bike lightweight but still very durable.
  • The adjustable seat (15" to 18") allows for the perfect fit (your child should be able to place both feet on the ground simultaneously while seated).
  • 6 speed settings (3 in "Limited" mode plus 3 more in "full power" mode).
