As a gold level dealer and having been an authorized dealer since 2003, we have trained many new riders on every Trikke offering to date. 

We believe the 8.5 Convertible is the most versatile Trikke to date.  The 8.5 Convertible can be fitted with the original solid poly wheel... fast and smooth... as well as the versatile air filled tire.  The challenge is the rear wheel change out requires moving the brake.  That is a solid 30 minute hassel.   HOWEVER... If you swap the front air for a solid poly wheel, you get almost all the benefit ot the poly.  So... Buy the 8.5 Air... get an extra solid poly for the front and you can retool in minutes for either smooth (poly) or rough (sir) surfaces.

Placement of a poly wheel on the front of the T8.5 Air is an excellent option a new rided or an individual that wants the speed of the poly.
