Bright 48V LED Headlight

The Luminus Flux headlight has an output of 1100 Lumens and an effective range up to 80 meters. Rain or shine this powerful and bright headlight will keep the road illuminated and make you visible to approaching traffic, cyclists and pedestrians. 




Hydraulic Brakes

In tough terrain and fast speeds, you need to be able to trust the braking ability of your bike. That is why the Pioneer is fitted with powerful 180mm hydraulic disc brakes. These provide exceptional precision and stopping power.

    Well Designed! Works Well!

    This is a fun easy to use ebike. Nothing but hills where we live both large and small, we can now enjoy riding with the help of the battery. We love our bikes, they are well built and we feel safe riding them.
