My buddies older heavy steel 66cc cruiser has the 90mm front drum and coaster rear, he weighs 220 at least and it stops him as fast as my young son on his mnt bike with disks on pavement, when I rode the bike I could almost lock up the front drum and I weigh 190, so it might be worth putting one on. It is what is going on my Cruiser build for certain.
