It has been a bit more than 6 months since I bought the Spyder and I thought I would put a brief description of it here. It rides a bit different than a 2 wheel cycle and I put a few miles on it before I felt comfortable riding it to work in San Antonio traffic. Things like no hand brake, only a foot brake (so it can be registered as a car in Europe - one machine for world wide distribution), and you don't have to put your feet down when you stop. That said, it is a great ride and still gets a lot of lookers and comments. It is longer and wider to a 2 wheeler so it is also more obvious.
I have put saddle bags and a tail trunk on it, but it has a large trunk in front that holds just about anything I need for it to. I only need the others when I go to the grocery store. I also added more lights in the form of brake lights by the license plate and turn indicators on the bags. In addition I put fog light on front and I feel being seen requires being seen and lights catch your eyes.
For ride comfort put on a larger CeeBailey windscreen and added a radio. I also added a Gerbing heatroller for my jacket and eventually added stereo speakers in my helmet. A lambskin helps control tempurature a bit better on what has otherwise proven to be a comfortable seat.
The Rotax 990 appears to be a dependable and peppy engine with if you drop it a gear it zips past the slow movers.
I am a bit disappointed in the gas mileage but it is pushing a lot of air and 3 good sized tires.
All in all I am enjoying it, and if you family has urged you to stop riding 2 wheels, this makes a great compromise.
