We've had endless discussions about types of clipless pedals. I prefer Look style pedals as they have a large platform and I can, if need be, ride with my running shoes. I also have what they call "moveable cleats". Try the bike on a trainer with shoes clipped in and see if you can clip out. It should not be hard to do that.

Check in the open topic area for opinions about pedals. They abound!

Sounds exciting that you are getting a bike! It's like trying on shoes, don't compromise. Make sure it feels right to you. Also, make sure they give you the correct size handlebars. They should only be as long as the distance between your shoulderblades.

I'd suggest a steel frame over an aluminum one if you can afford it. Aluminum is a much harder ride as it doesn't cushion you as well on the road. My 1st bike was steel. I still ride it and love the feel!

Good luck and let us know the outcome!
