Silicone foam grip installed on Catrike recumbent trike

Conventional foam grips on recumbent trikes split over time and degrade from elements and time. We have sourced durable silicone grips with better durability properties. By replacing stock OEM grips on a Catrike recumbent trike (or Greenspeed, or most brands that come with bar-end shifters) with these thick, closed-foam silicone grip pairs, we can prevent costly maintenance in the future.

We have just finished putting together an HP Velotechnik Gekko FX26 folding trike outfitted with a Neodrive 250W electric-assist system.

This is a very nice system and hard to find. The first test drive in front of the shop was on level ground, but the system seemed quite powerful.

We will have an HP Velotechnik Gekko FX26 folding trike outfitted with a Bionx 350W electric-assist system in the shop and available for test-riding on 27 August 2015.

This is a very nice system and hard to find.

The new Gekko FXS designed for children and adults up to 5'-11" will make its debut appearance at AlphaBENT's Northern California shop in Sacramento.
