Hi David Thanks for showing interest in the bike .Well first of all the brakes are shimano roller brakes which work very well but you must keep them lubricated with a special greese they make . Then theres the chainguard which is very high quality plastic and a very precise fit, not to easy to take off and put back at first,but you get used to it.Another interesting thing is the torque sensor which is located in the rear dropout, yet easy to ajust when you know how.All in all a great bike very comfortable, lots of good practical features like when it goes dark the lights come on.You have got to admire the Dutch they know what they are doing
