Additional FeaturesThis concept motorbike was designed to be very light but with
great suspension and good brakes.

An additional goal was to make a breakthrough in seat height
adjustment for a trail bike (29 inches to over 37 inches with the
motorcycle type seat.

Bicycle seats on a standard seat post have a great range of seat
heights and seat type options plus allow for the use of many
bicycle rack and saddlebag/basket options.

The ground clearance is adjusted with fork tube in triple clamp
positions and multiple shock mounting positions.

Foot pegs have multiple mounting hole positions forward and aft
including a very aft position for trials riding.


Slick has been registered in Colorado as a 30 MPH scooter/moped and
can navigate city traffic with speed and agility.

Slick has also proved its capability on very knarley trails because
of its power and very light weight.

Slick is looking forward to being ridden and tuned for motorcycle
trials competition. Slick weighs less than any other gas or electric
full-sized trials motorcycle.

The ability to quickly change seats and saddle bags on seats, and
seat height allows a high degree of flexibility for each ride and
different riders
