I have these units on my daughter's Fatboy. She tore her ACL and I did not want her riding clipless but wanted a grippy platform for her. These fit the bill at the right price. The studs are just long and sharp enough to hold onto her shoe without feeling dangerous. She did suffer some shin bang at first but got used to them and has had very few issues since. The pedals look sweet and provide a wide and long enough surface area while being open enough to shed mud. She's not ridden them in the winter yet but I presume they'll shed snow similarly well. After an MTB season, with plenty of mud and water, the bearings still spin smoothly and there are no worries about strength for her 150 lbs. You can't go wrong with these if you wanna go flat.
