I gave this guy a card . Trike powered by a 1200cc BMW bike motor . Quite fast( not gona be left behind by many cars or bikes) has a ramp in the rear that allows the wheel chair to drive in and lock . Has 2 jump seats behind it for pass. Can be driven by a person using an seat that fits where the wheel chair would go .That way a non handicap person can have fun too. $$$$ 56,000 not that bad for what it is . Tail gate is remote control electric. All hand controls.
