Who here can say what brakes work best for motoriized bicycling application. I have just purchased and using a 70mm drum front hub brake that seems to work ok. Maybe was expecting more but it still is new so most likely needs to get hot a few times and try it in city traffic and keep the cable adjustment tight for faster braking. Only have one brake on the bike at the moment. The front wheel brake hub. Still getting used to the hub brake using cable adjustments, removing all the slack makes it work much better as for stopping power.
