The Trident Chameleon is the top Tandem Trike that we stock. It features independent pedaling as standard equipment, and it adds a third disc brake on the rear wheel. Additionally, it sports a Sram Dual Drive rear hub that multiplies the shifting system to a whopping 81 speeds in order to be able to pedal slowly up the hills and speed faster than most on the flat and down the hills. It converts to a single Trike if you want to ride without your partner. For full specs, click HERE.
